text: Thugs of Hindostan

text: Premise

text: The film tells a historical fiction story set in 1795, when the Indian subcontinent was known as Hindustan or Hindostan, where Indian bandits known as Thugs (from the Hindustani word "thug") posed a serious challenge to the expanding British East India Company which had seized control of large parts of India.[4] The film follows a band of Thugs led by Khudabaksh Azaad (Amitabh Bachchan), who poses a grave threat to the British East India Company as he aspires to free the country from the British. Alarmed, John Clive (Lloyd Owen), a British commander, sends Firangi Mallah (Aamir Khan), a small-time Thug from Awadh, to infiltrate and counter the threat.[3]

text: Development

text: In September 2016, Yash Raj Films' next project titled Thugs of Hindostan was announced, and would feature Aamir Khan and Amitabh Bachchan. The lead actress was not yet finalized at the time.[8] The film was initially titled only Thug; it was set for a release on Diwali in 2018.[9] Hrithik Roshan, who was initially approached with the film's leading role, suggested some changes to the script. The film producer Aditya Chopra agreed; meanwhile, Acharya approached Khan with the script, who agreed to do the film with no changes to the storyline.[10] Later, in November 2016, Khan also requested that the script be reworked, particularly the character of the leading actress, and put the project on hold.[11] Meanwhile, he grew his hair and beard for his look in the film.[12]

text: By February 2017, Khan had prepared his look for the film.[13] In the same month, Shraddha Kapoor gave a costume look test and audition for the film.[14] In March 2017, it was reported that Khan suggested Fatima Sana Shaikh's name for a role in the film; while denying rumours of casting, Sheikh expressed her eagerness to work in the project.[15] In May 2017, Shaikh was confirmed to play a role in the film, with her audition look being revealed.[16] She replaced Kapoor.[17] Kaif was confirmed to star in the film on Yash Raj Films' official website.[17] Khan, Bachchan and Acharya met during the month of May to discuss script changes.[18] Contrary to initial reports, the film is not based on Philip Meadows Taylor's 1839 novel Confessions of a Thug (which was about Indian thugs) ; the film tells a fictional story based on historical events. Acharya links the misunderstanding to the word thug appearing in both works.[19] Khan also denied rumours of Thugs of Hindostan being inspired by Pirates of the Caribbean, stating in May 2017 that they are both simply action-adventure productions, among many others in the action-adventure film genre, such as the Indiana Jones series.[20]

text: Thugs of Hindostan is Khan's second time collaborating with Vijay Krishna Acharya and Katrina Kaif, after Dhoom 3 (2013).[21] It also marked the first collaboration between Khan and Bachchan.[22] Bachchan and Khan were supposed to star together in the Indra Kumar-directorial Rishta, planned during the late 1990s, but the project was shelved.[19] Besides Roshan, Jackie Shroff, Alia Bhatt, and Deepika Padukone were to be a part of the film, but turned down the role.[23][6] For his look, Khan also underwent permanent ear and nose piercing.[24]

text: In making Thugs of Hindostan, Acharya wanted to give a twist to period drama films and thus made what he considered "an irreverent film which has a chapter that is not very noble".[19] He made the film a visual "spectacle", considering the difficulty in bringing audiences to theatres.[19] Khan said his character was someone "who cannot be trusted at all – [so it's the] very opposite of Dangal … He's a very slippery character. He has no scruples at all – for money he can sell his mother out. He's like that."[25] Kaif said that she does not have much action to do in the film, compared to her previous action roles, in particular Tiger Zinda Hai (2017).[26] Bachchan wore iron armour for playing his character, the second time he did so after his 1988 film Shahenshah.[27] In addition, he also wore a pagri, grew long hair and learned sword-fighting.[19] Most of Bachchan's action sequences were situated in rainy settings.[19]

text: Principal photography

text: Thugs of Hindostan's estimated production budget is ₹3 billion (US$42 million), making it the most expensive Bollywood film.[2] It was initially planned to be produced on a budget of ₹900 million, but the budget was overrun while filming.[28] Filming commenced on 5 June 2017 in Malta.[22] Two ships were constructed in Malta for the purpose of filming; shooting was heavily guarded to prevent leaks from sets.[29] The ships were built by over 1000 people working together and weighed 200,000 kg each.[30] By 28 June 2017, Bachchan finished filming his first schedule in Malta.[31] In middle July, Khan took a break from filming and went on a vacation to Italy.[32]

text: Chopra, who was not impressed with the film's action sequences filmed in Malta, had them filmed again in Yash Raj Films' studio.[33] It was reported that busy with filming for Thugs of Hindostan, Khan would be unable to promote his film Secret Superstar (2017) properly.[34] However, in October 2017, Khan took a break from filming to promote his film.[35] In August 2017, Bachchan fractured his rib cage while shooting, but had to continue filming since the schedule was tight.[35] The film's dance sequence, which featured Bachchan, among others, and choreographed by Prabhu Deva was filmed in October 2017.[36] When filming was not taking place, the cast, along with the crew, wore face masks to avoid contracting common cold.[37] In September 2017, photographers of the Filmfare magazine captured Khan while filming, and leaked his look.[38] An upset Khan increased security surveillance on film sets.[39] The same month, Bachchan's look was also leaked online.[40] Khan stated that "this shouldn't have happened" and it foiled plans for later look releases.[41]

text: Filming also took place in Thailand, from 6 December 2017.[42] The schedule was wrapped up on 26 December 2017.[43] Some sequences were also shot in Mehrangarh Fort, Jodhpur.[44] After Bachchan experienced discomfort on set, a team of doctors visited him in Jodhpur. His wife, Jaya Bachchan stated that his heavy costumes hurt his back and neck.[45] The stunts aggravated his pre-existing neck and shoulder pain, which was a result of past injuries from stunts he did for filming in the 1970-80s.[46] Bachchan stated that he was back to normal.[47] The film's shooting was put on a short hiatus as a result of his injury.[48] He resumed filming on 13 March 2018.[49][50] The film's climax sequence was filmed in Jodhpur, Rajasthan in late March 2018.[51][52]

The following day, a motion poster of Khudabaksh, the commanding thug played by Bachchan, was released.[56] This was the first of a systematic marketing campaign that introduced the film's characters to the general public consistently throughout the week, using motion posters. On 19 September, the second character to be revealed was the archer Zafira, played by Shaikh.[57] John Clive, played by Owen, a ruthless British leader, was revealed on 20th September.[58] Suraiyya, a dancer played by Kaif, was displayed on 21 September.[59] 3 days later, the poster of Firangi, played by Khan, who was an eccentric-looking, donkey-riding thug, was revealed.[60]

text: On 26 September, Khan and Bachchan released a promotional video which featured them speaking in Telugu and Tamil, urging native audiences to watch the film.[6] On 27 September, Yash Raj Films' founder Yash Chopra's 86th birthday, the film's trailer was released on YouTube.[61] The trailer launch was held in Carnival Cinemas, Wadala, Mumbai, on India’s biggest IMAX screen, along with the presence of the film's cast.[62] The trailer crossed 30 million views on YouTube on the first day,[3] and crossed 32 million views across digital social media platforms in 24 hours.[63] Dubbed versions were also launched in Tamil by Kamal Haasan and in Telugu by S. S. Rajamouli.[64] It is set to be released in India during the week of the Diwali[a] festival, on 8 November 2018.[65][3] They also planned to release the film in China, where Khan's previous films were successful, including 3 Idiots (2009), PK (2014), Dangal (2016) and Secret Superstar (2017).[66]

text: On 8 October, a five minute behind-the-scenes video which details the film's ship-construction process in Malta, titled "Chapter 1: Building the Ships," was posted on Yash Raj Films' YouTube channel.[67] The following day, another making video was released, which mentioned the process that went into filming on the constructed ships, titled "Chapter 2: Shooting on the Ships".[68] On 10 October 2018, a third making video titled "Chapter 3: Destroying the Ship" was released, when one of the constructed ships had to be destroyed for a one-take shot.[69] The film’s second still poster was released on 13 October.[70] On 15 October, a still from the song "Vashmalle", which was directed by Prabhu Deva and features Khan and Bachchan dancing, was released. Acharya revealed that the song would feature Khan and Bachchan's characters getting drunk and dancing.[71] Meanwhile, Chinese distributors refused to release the film in China on the same day as India.[72]

text: On 17 October, YRF released a one-minute long clip of the song "Vashmalle" from the film, featuring a dance montage featuring Bachchan and Khan, on their Youtube channel.[73] A fourth making video was released on 19 October 2018, titled "Chapter 4: Training For Action", which revealed the schedule undergone by the cast for preparing the part of their character.[74] On 23 October, Yash Raj Films released a full four-minute lyrical video for the song "Vashmalle."[75]  The following day, 24 October, a still from the song "Suraiyya" was released by the makers.[76] Later that day, a teaser of the song was released on YouTube.[77]  On 25 October, a behind-the-scenes video for the "Suraiyya" song, detailing its conception and rehearsals, was released.[78]  On 29 October, YRF released a "Costume of the Thugs" video, revealing the concept art and design elements that went into constructing the characters' outfits.[79]

root

text: Tom Haverford

text: Background[edit]

text: Thomas Montgomery Haverford is an Indian American,[1] who changed his name from Darwish Sabir Ismael Gani to be more appealing in politics.[2] He is often assumed to be an immigrant by much of the Parks and Recreation staff (Leslie often assuming him to be Libyan), though, as he frequently reminds them, he hails from South Carolina, as does Ansari (although he does not have a Southern accent). He works as Leslie Knope's immediate subordinate at the Pawnee parks and recreation department, often serving as her right-hand man.[3] Tom displays an extremely sarcastic, mischievous and cocky attitude,[3][4] and frequently attempts to secure favors from local contractors. Tom has demonstrated his talent and passion for entrepreneurship in many occasions, including Entertainment 720, Rent-A-Swag, and Tom's Bistro.

tag: p

text: He takes his appearance very seriously, often donning office-casual polo shirts, as well as fitted suits with boat shoes.[3] He also buys clothing from the boys' collection at Brooks Brothers ("Telethon"). In "Go Big or Go Home," Tom also boasted about ladies' sneakers he bought from his workplace during Pawnee's government shutdown. Though it is not explicitly said, it's assumed Tom worked at Lady Foot Locker, where his best friend Jean-Ralphio Saperstein has a job too ("Woman of the Year"). He later opens up his own luxurious clothing-rental store for growing teens, Rent-A-Swag, and employs Jean-Ralphio's sister Mona Lisa Saperstein. Tom married his Canadian-born college friend Wendy to secure her U.S. citizenship (a green card marriage). Despite the marriage, Tom aggressively flirts with other women, which has prompted confusion from people unfamiliar with his arrangement with Wendy.[4][5] He is constantly pursuing women even during his marriage, as far as going to strip clubs, hitting on Ann Perkins, distributing copies of his house keys to beautiful women, and judging at the Miss Pawnee pageant.

text: Tom has complete authority over the Pawnee tennis court reservation system, which has brought him into close contact with many attractive female tennis enthusiasts.[6] Tom’s heroes include Tiger Woods, Vin Diesel, Michael Bolton, Flo Rida, Patrick Jane, Paul Walker, and Jamie Foxx.[6] He has a very high image of himself and brags that people view him as a "Brown Superman with a Beard" and has also asked to be introduced as "The Brown Gosling". He is very appreciative of pop culture and the idea of 'swag', very often expressed in his vernacular (e.g. SSerts instead of desserts in "Soulmates"). Tom often teams with April Ludgate and sometimes Donna Meagle to prank and harass Jerry Gergich. He also finds Ben Wyatt an easy target of tease.

text: Storyline[edit]

text: Season one[edit]

text: Tom appears lackadaisical about his work at the parks department and regularly undermines Leslie. He plays online Scrabble against his superior, Ron Swanson, during work time and loses on purpose in order to further his career. Ron, who believes in as little government interference as possible, approvingly states of Tom, "He doesn’t do a lot of work around here. He shows zero initiative. He’s not a team player. He never wants to go that extra mile. Tom is exactly what I’m looking for in a government employee."[7] Tom is often chosen to go on field projects with Leslie. He is also known for abusing his small amount of public power for self-benefit. Tom studies the culture of pickup artists and engages in a practice he calls "peacocking", which involves finding a visual element that makes him stand out in public like a peacock. In one such date, he wears a woman's orange hat, which others find ridiculous.[8]

text: Season two[edit]

text: Ron discovers Tom's green card marriage with Wendy, but agrees to keep it secret, especially after Tom discovers Ron secretly moonlights as a nightclub jazz musician.[9] Tom and Wendy get a divorce shortly after she gets her citizenship. Although he initially appears fine, Tom realizes he did in fact harbor feelings for Wendy and regrets the parting. At the end of Season 2, Tom meets Lucy, a bartender at the Snake Hole Lounge. As of the finale, the two are dating.[10]

text: Season three[edit]

text: At the beginning of Season 3, Tom is seen working at an apparel store as a sales associate while the government is on furlough. Lucy eventually breaks up with him, and reveals that their relationship ended because Tom spent too much time talking about his ex-wife's relationship with Ron Swanson. As an attempt to exact revenge on Ron, Tom brings Ron's ex-wife Tammy as a date to an event organized by the Parks department. The night ends in chaos with Ron and Tammy being arrested and getting married. It is later revealed in the episode "Indianapolis" that Tom has created his own cologne scent called "Tommy Fresh". In the season finale, Tom quits his job at the Parks Department to work at Entertainment 720 with Jean-Ralphio.

text: Season four[edit]

text: Tom begins working at Entertainment 720 and offers the shoeshinist at city hall, Andy Dwyer, a job, which Andy turns down. Entertainment 720 goes bankrupt due to their massive overspending and no business model and Tom decides to throw one last party which Lucy attends and he confesses to her that he is broke and jobless. Ron tries to persuade Tom to take his old job back, departing from Tom's early storyline by saying he does his job well and keeps the bosses off Ron's back, but doesn't overachieve to the point where the Parks department is tasked to do extra assignments. Tom initially refuses but eventually agrees. After his joking style made Ann Perkins smile at a Valentine's Day party, she decides to meet him for a date which his antics immediately made her regret. However, after several fits and starts, Tom has convinced Ann to keep seeing him, even though he's oblivious to (or ignoring) her disgust at allowing herself to do so.

text: Season five[edit]

text: Tom finally begins what appears to be a reputable business, based off an idea he came up with during a fundraiser for Jerry in "Halloween Surprise". The idea, aptly titled "Rent-a-Swag" is to rent his own high-end clothing to middle school boys whose mothers don't want to constantly be buying them new articles of clothing through puberty that they will grow out of quickly.

text: Season six[edit]

text: Tom learns that Jean-Ralphio's dad, Dr. Saperstein, is his business competitor, and struggles to keep Rent-a-Swag afloat, before finally giving in and selling Rent-a-Swag. He tries to focus on his job, helping Leslie get fluoride added to the water in Pawnee, and helping to set up the unity concert. While assisting Nadia Stasky, a beautiful and humorous doctor, at the Parks and Recreation office, Tom attempts to woo her and she later agrees to go out with him. The two pursue a relationship, and before leaving on a business trip to Rwanda, Nadia agrees to call him when she returns. During a meeting, Tom meets a man who likes his ideas and helps him jump-start his idea for a restaurant, Tom's Bistro.

text: Season seven[edit]

text: Now in 2017, Tom's Bistro has become very successful. After reuniting with his ex-girlfriend Lucy, he convinces her to move from Chicago to Pawnee and work at the Bistro. Shortly thereafter, they begin dating and he eventually proposes to her, which she accepts. In a series of flash-forwards in the finale, it is shown that Tom loses a great amount of money after unsuccessfully attempting to franchise Tom's Bistro. However, he later becomes a success again by writing a book about his many failures and how others may be able to achieve success.

text: Critical reception[edit]

text: Aziz Ansari, who was particularly acclaimed during the first season for his role as Tom Haverford,[1][3][11] received similar praise in the second season as well.[3][12] Alan Sepinwall, television columnist with The Star-Ledger, described Tom as the funniest of the characters during the first season,[11] and Jonah Weiner of Slate.com, who was critical of the first season, said Tom was "the brightest spot."[3] Paste ranked him No. 10 in their list of the 20 Best Characters of 2011.[13]

text: The Boy in the Striped Pyjamas is a 2006[1] Holocaust novel by Irish novelist John Boyne. Unlike the months of planning Boyne devoted to his other books, he said that he wrote the entire first draft of  The Boy in the Striped Pyjamas in two and a half days, barely sleeping until he got to the end.[1] (He did, however, commit to nearly 20 years of research, reading and researching about the Holocaust as a teenager before the idea for the novel even came to him.) As of March 2010, the novel had sold more than five million copies around the world.[2]  In both 2007 and 2008, it was the best selling book of the year in Spain, and it has also reached number one on the New York Times bestseller list,[3] as well as in the UK, Ireland, and Australia.[not verified in body] The book was adapted in 2008 as a film of the same name.

text: Plot[edit]

text: Bruno is a 9-year-old boy growing up during World War II in Berlin. He lives with his parents, his 12-year-old sister Gretel and maids, one of whom is called Maria. After a visit by Adolf Hitler, Bruno's father is promoted to Commandant, and the family has to move to "Out-With" because of the orders of "The Fury" (Bruno's naïve interpretation of the word "Führer"). Bruno is initially upset about moving to Out-With (in actuality, Auschwitz)[4] and leaving his friends, Daniel, Karl and Martin. From the house at Out-With, Bruno sees a camp in which the prisoners wear striped pyjamas. One day, Bruno decides to explore the strange wire fence. As he walks along the fence, he meets a Jewish boy named Shmuel, who he learns shares his birthday. Shmuel says that his father, grandfather, and brother are with him on this side of the fence, but he is separated from his mother. Bruno and Shmuel talk and become very good friends, although Bruno still does not understand very much about Shmuel and his side of the fence. Nearly every day, unless it's raining, Bruno goes to see Shmuel and sneaks him food. As the meetings go on, and Shmuel gets more and more skinny, Bruno's naïveté is proved, as he never realizes he is living beside a concentration camp.

text: When lice eggs are discovered in Bruno's hair he is forced to get all of his hair shaved off. Bruno comments that he looks like Shmuel, and Shmuel agrees, except that Bruno is fatter. Bruno's mother eventually persuades his father to take them back to Berlin and stay at Out-With without them.

text: The next day Bruno concocts a plan with Shmuel to sneak into the camp to look for Shmuel's father. Shmuel brings a set of prison clothes (which look to Bruno like striped pyjamas), and Bruno leaves his own clothes outside the fence. As they search the camp, both children are rounded up along with a group of prisoners on a "march". They are forced to remove their clothing and are led into a gas chamber. In the gas chamber, Bruno apologizes to Shmuel for not finding his father and tells Shmuel that he is Bruno's best friend for life. It's unknown if Shmuel answers him, because as soon as the door is closed, the lights go out and all is chaos. However, Bruno is determined that even in chaos, he will never let go of Shmuel's hand.

text: Critics' reviews[edit]

text: Kathryn Hughes, writing in The Guardian, calls the novel "a small wonder of a book". While she comments on "the oddness of Auschwitz security being so lax that a child prisoner could make a weekly date with the commandant's son without anyone noticing", she describes the novel as "something that borders on fable", arguing that "Bruno's innocence comes to stand for the willful refusal of all adult Germans to see what was going on under their noses".[5]

text: Nicholas Tucker, writing in The Independent, calls the novel "a fine addition to a once taboo area of history, at least where children's literature is concerned. It provides an account of a dreadful episode short on actual horror but packed with overtones that remain in the imagination. Plainly and sometimes archly written, it stays just ahead of its readers before delivering its killer punch in the final pages."[6]

text: Ed Wright, writing in The Age of Melbourne, calls the novel "a touching tale of an odd friendship between two boys in horrendous circumstances and a reminder of man's capacity for inhumanity". He felt that "Bruno's friendship with Shmuel is rendered with neat awareness of the paradoxes between children's naïve egocentricity, their innate concept of fairness, familial loyalty and obliviousness to the social conventions of discrimination". He concludes by observing that "The Boy in the Striped Pyjamas is subtitled A Fable and, as in other modern fables such as Antoine de St.-Exupéry's The Little Prince, Boyne uses Bruno to reveal the flaws in an adult world".[7]

text: A. O. Scott, writing in The New York Times, questioned the author and publisher's choice to intentionally keep the Holocaust setting of the book vague in both the dust jacket summary and the early portion of the novel, writing: "Boyne's reluctance to say as much can certainly be defended, not least on the grounds that the characters in a story about the Holocaust are themselves most likely unaware of the scale and historical importance of their experiences. To recreate those experiences faithfully might require undoing some of the readers' preconceptions". However Scott felt this undermined the work, saying: "A young reader who knows little or nothing about the mass murder of European Jews by the Nazis will not know much more after reading The Boy in the Striped Pajamas, while one who has read other books on the topic — Jerry Spinelli's Milkweed, say, or Anne Frank's diary — may be irritated by the book’s evasions and euphemisms. There is something awkward about the way Boyne manages to disguise, and then to disclose, the historical context". Scott concludes that "[T]o mold the Holocaust into an allegory, as Boyne does here with perfectly benign intent, is to step away from its reality".[8]

text: Rabbi Benjamin Blech offered a historical criticism, contending that the premise of the book and subsequent film – that there could be a child of Shmuel's age in Auschwitz – was impossible, writing of the book: "Note to the reader: there were no 9-year-old Jewish boys in Auschwitz – the Nazis immediately gassed those not old enough to work."[9] Rabbi Blech affirmed the opinion of a Holocaust survivor friend that the book is "not just a lie and not just a fairytale, but a profanation". Blech acknowledges the objection that a "fable" need not be factually accurate; he counters that the book trivializes the conditions in and around the death camps and perpetuates the "myth that those [...] not directly involved can claim innocence", and thus undermines its moral authority.  Students who read it, he warns, may believe the camps "weren't that bad" if a boy could conduct a clandestine friendship with a Jewish captive of the same age, unaware of "the constant presence of death".[10]

text: Holocaust scholar Henry Gonashk rebuts Blech's historical contention in his book Hollywood and the Holocaust, writing that "[T]he rabbi found implausible Shmuel's very existence in the camp", but stating that "Blech is factually incorrect. In fact, there were male (though apparently not female) children at Auschwitz. In 1944, for example, according to the Nazis' meticulous records, there were 619 male children at the camp, ranging in age from one month to fourteen years old. Some of the boys were employed by the Nazis as camp messengers, while others were simply kept around as mascots and curiosities. Probably some of these children were sexually abused by the guards. Of course, thousands of other children at Auschwitz (including all the girls who arrived at the camp) were gassed".[11]


document_title: Stimulus (physiology)

question_text: which of the following refers to the change from a physical stimulus to a neural impulse

text: Stimulus (physiology)

text: Types[edit]

text: Internal[edit]

text: Homeostatic imbalances[edit]

text: Homeostatic imbalances are the main driving force for changes in the body. These stimuli are monitored closely by receptors and sensors in different parts of the body. These sensors are mechanoreceptors, chemoreceptors and thermoreceptors that, respectively, respond to pressure or stretching, chemical changes, or temperature changes. Examples of mechanoreceptors include baroreceptors which detect changes in blood pressure, Merkel's discs which detect sustained touch and pressure, and hair cells which detect sound stimuli. Homeostatic imbalances that can serve as internal stimuli include nutrient and ion levels in the blood, oxygen levels, and water levels. Deviations from the homeostatic ideal may generate a homeostatic emotion, such as pain, thirst or fatigue, that motivates behavior that will restore the body to stasis (such as withdrawal, drinking or resting).[1]

text: Blood pressure[edit]

text: Blood pressure, heart rate, and cardiac output are measured by stretch receptors found in the carotid arteries. Nerves embed themselves within these receptors and when they detect stretching, they are stimulated and fire action potentials to the central nervous system. These impulses inhibit the constriction of blood vessels and lower the heart rate. If these nerves do not detect stretching, the body determines perceives low blood pressure as a dangerous stimulus and signals are not sent, preventing the inhibition CNS action; blood vessels constrict and the heart rate increases, causing an increase in blood pressure in the body.[2]

text: External[edit]

text: Touch and pain[edit]

text: Sensory feelings, especially pain, are stimuli that can elicit a large response and cause neurological changes in the body. Pain also causes a behavioral change in the body, which is proportional to the intensity of the pain. The feeling is recorded by sensory receptors on the skin and travels to the central nervous system, where it is integrated and a decision on how to respond is made; if it is decided that a response must be made, a signal is sent back down to a muscle, which acts appropriately according to the stimulus.[1] The postcentral gyrus is the location of the primary somatosensory area, the main sensory receptive area for the sense of touch.[3]

text: Pain receptors are known as nociceptors. Two main types of nociceptors exist, A-fiber nociceptors and C-fiber nociceptors. A-fiber receptors are myelinated and conduct currents rapidly. They are mainly used to conduct fast and sharp types of pain. Conversely, C-fiber receptors are unmyelinated and slowly transmit. These receptors conduct slow, burning, diffuse pain.[4]

text: The absolute threshold for touch is the minimum amount of sensation needed to elicit a response from touch receptors. This amount of sensation has a definable value and is often considered to be the force exerted by dropping the wing of a bee onto your cheek from a distance of one centimeter. This value will change based on the body part being touched.[5]

text: Vision[edit]

text: Vision provides opportunity for the brain to perceive and respond to changes occurring around the body. Information, or stimuli, in the form of light enters the retina, where it excites a special type of neuron called a photoreceptor cell. A local graded potential begins in the photoreceptor, where it excites the cell enough for the impulse to be passed along through a track of neurons to the central nervous system. As the signal travels from photoreceptors to larger neurons, action potentials must be created for the signal to have enough strength to reach the CNS.[2] If the stimulus does not warrant a strong enough response, it is said to not reach absolute threshold, and the body does not react. However, if the stimulus is strong enough to create an action potential in neurons away from the photoreceptor, the body will integrate the information and react appropriately. Visual information is processed in the occipital lobe of the CNS, specifically in the primary visual cortex.[2]

text: The absolute threshold for vision is the minimum amount of sensation needed to elicit a response from photoreceptors in the eye. This amount of sensation has a definable value and is often considered to be the amount of light present from someone holding up a single candle 30 miles away, if one's eyes were adjusted to the dark.[5]

text: Smell[edit]

text: Smell allows the body to recognize chemical molecules in the air through inhalation. Olfactory organs located on either side of the nasal septum consist of olfactory epithelium and lamina propria. The olfactory epithelium, which contains olfactory receptor cells, covers the inferior surface of the cribiform plate, the superior portion of the perpendicular plate, the superior nasal concha. Only roughly two percent of airborne compounds inhaled are carried to olfactory organs as a small sample of the air being inhaled. Olfactory receptors extend past the epithelial surface providing a base for many cilia that lie in the surrounding mucus. Odorant-binding proteins interact with these cilia stimulating the receptors. Odorants are generally small organic molecules. Greater water and lipid solubility is related directly to stronger smelling odorants. Odorant binding to G protein coupled receptors activates adenylate cyclase, which converts ATP to camp. cAMP, in turn, promotes the opening of sodium channels resulting in a localized potential.[6]

text: The absolute threshold for smell is the minimum amount of sensation needed to elicit a response from receptors in the nose. This amount of sensation has a definable value and is often considered to be a single drop of perfume in a six-room house. This value will change depending on what substance is being smelled.[5]

text: Taste[edit]

text: Taste records flavoring of food and other materials that pass across the tongue and through the mouth. Gustatory cells are located on the surface of the tongue and adjacent portions of the pharynx and larynx. Gustatory cells form on taste buds, specialized epithelial cells, and are generally turned over every ten days. From each cell, protrudes microvilli, sometimes called taste hairs, through also the taste pore and into the oral cavity. Dissolved chemicals interact with these receptor cells; different tastes bind to specific receptors. Salt and sour receptors are chemically gated ion channels, which depolarize the cell. Sweet, bitter, and umami receptors are called gustducins, specialized G protein coupled receptors. Both divisions of receptor cells release neurotransmitters to afferent fibers causing action potential firing.[6]

text: The absolute threshold for taste is the minimum amount of sensation needed to elicit a response from receptors in the mouth. This amount of sensation has a definable value and is often considered to be a single drop of quinine sulfate in 250 gallons of water.[5]

text: Sound[edit]

text: Changes in pressure caused by sound reaching the external ear resonate in the tympanic membrane, which articulates with the auditory ossicles, or the bones of the middle ear. These tiny bones multiply these pressure fluctuations as they pass the disturbance into the cochlea, a spiral-shaped bony structure within the inner ear. Hair cells in the cochlear duct, specifically the organ of Corti, are deflected as waves of fluid and membrane motion travel through the chambers of the cochlea. Bipolar sensory neurons located in the center of the cochlea monitor the information from these receptor cells and pass it on to the brainstem via the cochlear branch of cranial nerve VIII. Sound information is processed in the temporal lobe of the CNS, specifically in the primary auditory cortex.[6]

text: The absolute threshold for sound is the minimum amount of sensation needed to elicit a response from receptors in the ears. This amount of sensation has a definable value and is often considered to be a watch ticking in an otherwise soundless environment 20 feet away.[5]

text: Equilibrium[edit]

text: Semi circular ducts, which are connected directly to the cochlea, can interpret and convey to the brain information about equilibrium by a similar method as the one used for hearing. Hair cells in these parts of the ear protrude kinocilia and stereocilia into a gelatinous material that lines the ducts of this canal. In parts of these semi circular canals, specifically the maculae, calcium carbonate crystals known as statoconia rest on the surface of this gelatinous material. When tilting the head or when the body undergoes linear acceleration, these crystals move disturbing the cilia of the hair cells and, consequently, affecting the release of neurotransmitter to be taken up by surrounding sensory nerves. In other areas of the semi circular canal, specifically the ampulla, a structure known as the cupula—analogous to the gelatinous material in the maculae—distorts hair cells in a similar fashion when the fluid medium that surrounds it causes the cupula itself to move. The ampulla communicates to the brain information about the head’s horizontal rotation. Neurons of the adjacent vestibular ganglia monitor the hair cells in these ducts. These sensory fibers form the vestibular branch of the cranial nerve VIII.[6]

text: Cellular response[edit]

text: In general, cellular response to stimuli is defined as a change in state or activity of a cell in terms of movement, secretion, enzyme production, or gene expression.[7] Receptors on cell surfaces are sensing components that monitor stimuli and respond to changes in the environment by relaying the signal to a control center for further processing and response. Stimuli are always converted into electrical signals via transduction. This electrical signal, or receptor potential, takes a specific pathway through the nervous system to initiate a systematic response. Each type of receptor is specialized to respond preferentially to only one kind of stimulus energy, called the adequate stimulus. Sensory receptors have a well-defined range of stimuli to which they respond, and each is tuned to the particular needs of the organism. Stimuli are relayed throughout the body by mechanotransduction or chemotransduction, depending on the nature of the stimulus.[2]

text: Mechanical[edit]

text: In response to a mechanical stimulus, cellular sensors of force are proposed to be extracellular matrix molecules, cytoskeleton, transmembrane proteins, proteins at the membrane-phospholipid interface, elements of the nuclear matrix, chromatin, and the lipid bilayer. Response can be twofold: the extracellular matrix, for example, is a conductor of mechanical forces but its structure and composition is also influenced by the cellular responses to those same applied or endogenously generated forces.[8] Mechanosensitive ion channels are found in many cell types and it has been shown that the permeability of these channels to cations is affected by stretch receptors and mechanical stimuli.[9] This permeability of ion channels is the basis for the conversion of the mechanical stimulus into an electrical signal..

text: Chemical[edit]

text: Chemical stimuli, such as odorants, are received by cellular receptors that are often coupled to ion channels responsible for chemotransduction. Such is the case in olfactory cells.[10] Depolarization in these cells result from opening of non-selective cation channels upon binding of the odorant to the specific receptor. G protein-coupled receptors in the plasma membrane of these cells can initiate second messenger pathways that cause cation channels to open.

text: In response to stimuli, the sensory receptor initiates sensory transduction by creating graded potentials or action potentials in the same cell or in an adjacent one. Sensitivity to stimuli is obtained by chemical amplification through second messenger pathways in which enzymatic cascades produce large numbers of intermediate products, increasing the effect of one receptor molecule.[2]

text: Systematic response[edit]

text: Nervous-system response[edit]

text: Though receptors and stimuli are varied, most extrinsic stimuli first generate localized graded potentials in the neurons associated with the specific sensory organ or tissue.[6] In the nervous system, internal and external stimuli can elicit two different categories of responses: an excitatory response, normally in the form of an action potential, and an inhibitory response.[11] When a neuron is stimulated by an excitatory impulse, neuronal dendrites are bound by neurotransmitters which cause the cell to become permeable to a specific type of ion; the type of neurotransmitter determines to which ion the neurotransmitter will become permeable. In excitatory postsynaptic potentials, an excitatory response is generated. This is caused by an excitatory neurotransmitter, normally glutamate binding to a neuron's dendrites, causing an influx of sodium ions through channels located near the binding site.

text: This change in membrane permeability in the dendrites is known as a local graded potential and causes the membrane voltage to change from a negative resting potential to a more positive voltage, a process known as depolarization. The opening of sodium channels allows nearby sodium channels to open, allowing the change in permeability to spread from the dendrites to the cell body. If a graded potential is strong enough, or if several graded potentials occur in a fast enough frequency, the depolarization is able to spread across the cell body to the axon hillock. From the axon hillock, an action potential can be generated and propagated down the neuron's axon, causing sodium ion channels in the axon to open as the impulse travels. Once the signal begins to travel down the axon, the membrane potential has already passed threshold, which means that it cannot be stopped. This phenomenon is known as an all-or-nothing response. Groups of sodium channels opened by the change in membrane potential strengthen the signal as it travels away from the axon hillock, allowing it to move the length of the axon. As the depolarization reaches the end of the axon, or the axon terminal, the end of the neuron becomes permeable to calcium ions, which enters the cell via calcium ion channels. Calcium causes the release of neurotransmitters stored in synaptic vesicles, which enter the synapse between two neurons known as the presynaptic and postsynaptic neurons; if the signal from the presynaptic neuron is excitatory, it will cause the release of an excitatory neurotransmitter, causing a similar response in the postsynaptic neuron.[2] These neurons may communicate with thousands of other receptors and target cells through extensive, complex dendritic networks. Communication between receptors in this fashion enables discrimination and the more explicit interpretation of external stimuli. Effectively, these localized graded potentials trigger action potentials that communicate, in their frequency, along nerve axons eventually arriving in specific cortexes of the brain. In these also highly specialized parts of the brain, these signals are coordinated with others to possibly trigger a new response.[6]

text: If a signal from the presynaptic neuron is inhibitory, inhibitory neurotransmitters, normally GABA will be released into the synapse.[2] This neurotransmitter causes an inhibitory postsynaptic potential in the postsynaptic neuron. This response will cause the postsynaptic neuron to become permeable to chloride ions, making the membrane potential of the cell negative; a negative membrane potential makes it more difficult for the cell to fire an action potential and prevents any signal from being passed on through the neuron. Depending on the type of stimulus, a neuron can be either excitatory or inhibitory.[12]

text: Muscular-system response[edit]

text: Nerves in the peripheral nervous system spread out to various parts of the body, including muscle fibers. A muscle fiber and the motor neuron to which it is connected.[13] The spot at which the motor neuron attaches to the muscle fiber is known as the neuromuscular junction. When muscles receive information from internal or external stimuli, muscle fibers are stimulated by their respective motor neuron. Impulses are passed from the central nervous system down neurons until they reach the motor neuron, which releases the neurotransmitter acetylcholine (ACh) into the neuromuscular junction. ACh binds to nicotinic acetylcholine receptors on the surface of the muscle cell and opens ion channels, allowing sodium ions to flow into the cell and potassium ions to flow out; this ion movement causes a depolarization, which allows for the release of calcium ions within the cell. Calcium ions bind to proteins within the muscle cell to allow for muscle contraction; the ultimate consequence of a stimulus.[2]

text: Endocrine-system response[edit]

text: Vasopressin[edit]

text: The endocrine system is affected largely by many internal and external stimuli. One internal stimulus that causes hormone release is blood pressure. Hypotension, or low blood pressure, is a large driving force for the release of vasopressin, a hormone which causes the retention of water in the kidneys. This process also increases an individuals thirst. By fluid retention or by consuming fluids, if an individual's blood pressure returns to normal, vasopressin release slows and less fluid is retained by the kidneys. Hypovolemia, or low fluid levels in the body, can also act as a stimulus to cause this response.[14]

text: Epinephrine[edit]

text: Epinephrine, also known as adrenaline, is also used commonly to respond to both internal and external changes. One common cause of the release of this hormone is the Fight-or-flight response. When the body encounters an external stimulus that is potentially dangerous, epinephrine is released from the adrenal glands. Epinephrine causes physiological changes in the body, such as constriction of blood vessels, dilation of pupils, increased heart and respiratory rate, and the metabolism of glucose. All of these responses to a single stimuli aid in protecting the individual, whether the decision is made to stay and fight, or run away and avoid danger.[15][16]

text: Digestive-system response[edit]

text: Cephalic phase[edit]

text: The digestive system can respond to external stimuli, such as the sight or smell of food, and cause physiological changes before the food ever enters the body. This reflex is known as the cephalic phase of digestion. The sight and smell of food are strong enough stimuli to cause salivation, gastric and pancreatic enzyme secretion, and endocrine secretion in preparation for the incoming nutrients; by starting the digestive process before food reaches the stomach, the body is able to more effectively and efficiently metabolize food into necessary nutrients.[17] Once food hits the mouth, taste and information from receptors in the mouth add to the digestive response. Chemoreceptors and mechanorceptors, activated by chewing and swallowing, further increase the enzyme release in the stomach and intestine.[18]

text: Enteric nervous system[edit]

text: The digestive system is also able to respond to internal stimuli. The digestive tract, or enteric nervous system alone contains millions of neurons. These neurons act as sensory receptors that can detect changes, such as food entering the small intestine, in the digestive tract. Depending on what these sensory receptors detect, certain enzymes and digestive juices from the pancreas and liver can be secreted to aid in metabolism and breakdown of food.[2]

text: Methods and techniques[edit]

text: Clamping techniques[edit]

text: Intracellular measurements of electrical potential across the membrane can be obtained by microelectrode recording. Patch clamp techniques allow for the manipulation of the intracellular or extracellular ionic or lipid concentration while still recording potential. In this way, the effect of various conditions on threshold and propagation can be assessed.[2]

text: Noninvasive neuronal scanning[edit]

text: Positron emission tomography (PET) and magnetic resonance imaging (MRI) permit the noninvasive visualization of activated regions of the brain while the test subject is exposed to different stimuli. Activity is monitored in relation to blood flow to a particular region of the brain.[2]

text: Hindlimb withdrawal time[edit]

text: Sorin Barac et al. in a recent paper published in the Journal of Reconstructive Microsurgery monitored the response of test rats to pain stimuli by inducing an acute, external heat stimulus and measuring hindlimb withdrawal times (HLWT).[19]

text: World total primary energy supply (TPES), or "primary energy" differs from the world final energy consumption because much of the energy that is acquired by humans is lost as other forms of energy during the process of its refinement into usable forms of energy and its transport from its initial place of supply to consumers. For instance, when oil is extracted from the ground it must be refined into gasoline, so that it can be used in a car, and transported over long distances to gas stations where it can be used by consumers. World final energy consumption refers to the fraction of the world's primary energy that is used in its final form by humanity.

text: In 2014, world primary energy supply amounted to 155,481 terawatt-hour (TWh) or 13,541 Mtoe, while the world final energy consumption was 109,613 TWh or about 29.5% less than the total supply.[9] World final energy consumption includes products as lubricants, asphalt and petrochemicals which have chemical energy content but are not used as fuel. This non-energy use amounted to 9,404 TWh (809 Mtoe) in 2012.[11]

text: By the end of 2014, the total installed global power generating capacity is nearly 6.142 TW (million MW) which does not include the DG sets not connected to local electricity grids.[12] In 2014, world energy consumption for electricity generation was coal 40.8%, natural gas 21.6%, nuclear 10.6%, hydro 16.4%, 'others' (solar, wind, geothermal, biomass, etc.) 6.3% and oil 4.3%. Coal and natural gas were the most popular energy fuels for generating electricity. The world's electricity consumption was 18,608 TWh[citation needed] in 2012. This figure is about 18% smaller than the generated electricity, due to grid losses, storage losses, and self-consumption from power plants (gross generation). Cogeneration (CHP) power stations use some of the energy that is otherwise wasted for heating buildings or in industrial processes.

text: 2014 World electricity generation (23,816 TWh) by source (IEA, 2016)[13]

text: The United States Energy Information Administration regularly publishes a report on world consumption for most types of primary energy resources. For 2013, estimated world energy consumption was 5.67 × 1020 joules, or 157,481 TWh. According to the IEA the total world energy consumption was 143,851 TWh in 2008, 133,602 TWh in 2005, 117,687 TWh in 2000, and 102,569 TWh in 1990. Total world electricity consumption was 19,504 TWh in 2013, 16,503 TWh in 2008, 15,105 TWh in 2005, and 12,116 TWh in 2000.[2] In 2012 approximately 22% of world energy was consumed in North America, 5% was consumed South and Central America, 23% was consumed in Europe and Eurasia, 3% was consumed in Africa, and 40% was consumed in the Asia Pacific region.[1]

text: Recently there has been a large increase in international agreements and national Energy Action Plans, such as the EU 2009 Renewable Energy Directive, to increase the use of renewable energy due to the growing concerns about pollution from energy sources that come from fossil fuels such as oil, coal, and natural gas.[3][14] One such initiative was the United Nations Development Programme's World Energy Assessment in 2000 that highlighted many challenges humanity would have to overcome in order to shift from fossil fuels to renewable energy sources.[3] From 2000–2012 renewable energy grew at a rate higher than any other point in history, with a consumption increase of 176.5 million tonnes of oil. During this period, oil, coal, and natural gas continued to grow and had increases that were much higher than the increase in renewable energy. The following figures illustrate the growth in consumption of fossil fuels such as oil, coal, and natural gas as well as renewable sources of energy during this period.[1]

text: Trends[edit]

text: The energy consumption growth in the G20 slowed down to 2% in 2011, after the strong increase of 2010. The economic crisis is largely responsible for this slow growth. For several years now, the world energy demand is characterized by the bullish Chinese and Indian markets, while developed countries struggle with stagnant economies, high oil prices, resulting in stable or decreasing energy consumption.[18]

text: According to IEA data from 1990 to 2008, the average energy use per person increased 10% while world population increased 27%. Regional energy use also grew from 1990 to 2008: the Middle East increased by 170%, China by 146%, India by 91%, Africa by 70%, Latin America by 66%, the USA by 20%, the EU-27 block by 7%, and world overall grew by 39%.

text: In 2008, total worldwide primary energy consumption was 132,000 terawatt-hours (TWh) or 474 exajoules (EJ).[19] In 2012, primary energy demand increased to 158,000 TWh (567 EJ).[20]

text: Energy consumption in the G20 increased by more than 5% in 2010 after a slight decline of 2009. In 2009, world energy consumption decreased for the first time in 30 years by 1.1%, or about 130 million tonnes of oil equivalent (Mtoe), as a result of the financial and economic crisis, which reduced world GDP by 0.6% in 2009.[21]

text: This evolution is the result of two contrasting trends: Energy consumption growth remained vigorous in several developing countries, specifically in Asia (+4%). Conversely, in OECD, consumption was severely cut by 4.7% in 2009 and was thus almost down to its 2000 levels. In North America, Europe and the CIS, consumptions shrank by 4.5%, 5% and 8.5% respectively due to the slowdown in economic activity. China became the world's largest energy consumer (18% of the total) since its consumption surged by 8% during 2009 (up from 4% in 2008). Oil remained the largest energy source (33%) despite the fact that its share has been decreasing over time. Coal posted a growing role in the world's energy consumption: in 2009, it accounted for 27% of the total.

text: Most energy is used in the country of origin, since it is cheaper to transport final products than raw materials. In 2008, the share export of the total energy production by fuel was: oil 50% (1,952/3,941 Mt), gas 25% (800/3,149 bcm) and hard coal 14% (793/5,845 Mt).[22]

text: Most of the world's high energy resources are from the conversion of the sun's rays to other energy forms after being incident upon the planet. Some of that energy has been preserved as fossil energy, some is directly or indirectly usable; for example, via solar PV/thermal, wind, hydro- or wave power. The total solar irradiance is measured by satellite to be roughly 1361 watts per square meter (see solar constant), though it fluctuates by about 6.9% during the year due to the Earth's varying distance from the sun. This value, after multiplication by the cross-sectional area intercepted by the Earth, is the total rate of solar energy received by the planet; about half, 89,000 TW, reaches the Earth's surface.[23]

text: The estimates of remaining non-renewable worldwide energy resources vary, with the remaining fossil fuels totaling an estimated 0.4  yottajoule (YJ) or 4 × 1023 joules, and the available nuclear fuel such as uranium exceeding 2.5 YJ. Fossil fuels range from 0.6 to 3 YJ if estimates of reserves of methane clathrates are accurate and become technically extractable. The total power flux from the sun intercepting the Earth is 5.5 YJ per year, though not all of this is available for human consumption. The IEA estimates for the world to meet global energy demand for the two decades from 2015 to 2035 it will require investment of $48 trillion and "credible policy frameworks."[24]

text: According to IEA (2012) the goal of limiting warming to 2 °C is becoming more difficult and costly with each year that passes. If action is not taken before 2017, CO2 emissions would be locked-in by energy infrastructure existing in 2017. Fossil fuels are dominant in the global energy mix, supported by $523 billion subsidies in 2011, up almost 30% on 2010 and six times more than subsidies to renewables.[25]

text: Emissions[edit]

text: Global warming emissions resulting from energy production are an environmental problem. Efforts to resolve this include the Kyoto Protocol, which is a UN agreement aiming to reduce harmful climate impacts, which a number of nations have signed. Limiting global temperature increase to 2 degrees Celsius, thought to be a risk by the SEI, is now doubtful.

text: To limit global temperature to a hypothetical 2 degrees Celsius rise would demand a 75% decline in carbon emissions in industrial countries by 2050, if the population is 10 billion in 2050.[28] Across 40 years, this averages to a 2% decrease every year. In 2011, the emissions of energy production continued rising regardless of the consensus of the basic problem. Hypothetically, according to Robert Engelman (Worldwatch institute), in order to prevent collapse, human civilization would have to stop increasing emissions within a decade regardless of the economy or population (2009).[29]

text: Greenhouse gases are not the only emissions of energy production and consumption. Large amounts of pollutants such as sulphurous oxides (SOx), nitrous oxides (NOx), and particulate matter (PM) are produced from the combustion of fossil fuels and biomass; the World Health Organisation estimates that 7 million premature deaths are caused each year by air pollution.[30] Biomass combustion is a major contributor.[30][31][32] In addition to producing air pollution like fossil fuel combustion, most biomass has high CO2 emissions.[33]

text: Fossil fuels[edit]

text: The twentieth century saw a rapid twenty-fold increase in the use of fossil fuels. Between 1980 and 2006, the worldwide annual growth rate was 2%.[19] According to the US Energy Information Administration's 2006 estimate, the estimated 471.8 EJ total consumption in 2004, was divided as given in the table above, with fossil fuels supplying 86% of the world's energy:

text: Coal[edit]

text: In 2000, China accounted for 28% of world coal consumption, other Asia consumed 19%, North America 25% and the EU 14%. The single greatest coal-consuming country is China. Its share of the world coal production was 28% in 2000 and rose to 48% in 2009. In contrast to China's ~70% increase in coal consumption, world coal use increased 48% from 2000 to 2009. In practice, the majority of this growth occurred in China and the rest in other Asia.[34] China's energy consumption is mostly driven by the industry sector, the majority of which comes from coal consumption.[35]

text: World annual coal production increased 1,905 Mt or 32% in 6 years in 2011 compared to 2005, of which over 70% was in China and 8% in India. Coal production was in 2011 7,783 Mt, and 2009 6,903 Mt, equal to 12.7% production increase in two years.[36]

text: If production and consumption of coal continue at the rate as in 2008, proven and economically recoverable world reserves of coal would last for about 150 years. This is much more than needed for an irreversible climate catastrophe. Coal is the largest source of carbon dioxide emissions in the world. According to James Hansen the single most important action needed to tackle the climate crisis is to reduce CO2 emissions from coal.[37] Indonesia and Australia exported together 57.1% of the world coal export in 2011. China, Japan, South Korea, India and Taiwan had 65% share of all the world coal import in 2011.[38]

text: Oil[edit]

text: Coal fueled the industrial revolution in the 18th and 19th century. With the advent of the automobile, aeroplanes and the spreading use of electricity, oil became the dominant fuel during the twentieth century. The growth of oil as the largest fossil fuel was further enabled by steadily dropping prices from 1920 until 1973. After the oil shocks of 1973 and 1979, during which the price of oil increased from 5 to 45 US dollars per barrel, there was a shift away from oil.[41] Coal, natural gas, and nuclear became the fuels of choice for electricity generation and conservation measures increased energy efficiency. In the U.S. the average car more than doubled the number of miles per gallon. Japan, which bore the brunt of the oil shocks, made spectacular improvements and now has the highest energy efficiency in the world.[42] From 1965 to 2008, the use of fossil fuels has continued to grow and their share of the energy supply has increased. From 2003 to 2008, coal was the fastest growing fossil fuel.[43]

text: It is estimated that between 100 and 135 billion tonnes of oil has been consumed between 1850 and the present.[44]

text: Natural Gas[edit]

text: In 2009, the world use of natural gas grew 31% compared to 2000. 66% of this growth was outside EU, North America, Latin America, and Russia. Others include the Middle East, Asia, and Africa. The gas supply increased also in the previous regions: 8.6% in the EU and 16% in the North America 2000–2009.[45]

text: Nuclear power[edit]

text: As of 1 July 2016, the world had 444 operable grid-electric nuclear power reactors with 62 others under construction.[46] Since commercial nuclear energy began in the mid 1950s, 2008 was the first year that no new nuclear power plant was connected to the grid, although two were connected in 2009.[47][48]

text: Annual generation of nuclear power has been on a slight downward trend since 2007, decreasing 1.8% in 2009 to 2558 TWh, and another 1.6% in 2011 to 2518 TWh, despite increases in production from most countries worldwide, because those increases were more than offset by decreases in Germany and Japan. Nuclear power met 11.7% of the world's electricity demand in 2011. Source: IEA/OECD[6]

text: Renewable energy[edit]

text: Renewable energy is generally defined as energy that comes from resources that are not significantly depleted by their use, such as sunlight, wind, rain, tides, waves and geothermal heat.[50] Renewable energy is gradually replacing conventional fuels in four distinct areas: electricity generation, hot water/space heating, motor fuels, and rural (off-grid) energy services.[51]

text: Based on REN21's 2014 report, renewables contributed 19 percent to our energy consumption and 22 percent to our electricity generation in 2012 and 2013, respectively. This energy consumption is divided as 9% coming from traditional biomass, 4.2% as heat energy (non-biomass), 3.8% hydro electricity and 2% electricity from wind, solar, geothermal, and biomass. Worldwide investments in renewable technologies amounted to more than US$214 billion in 2013, with countries like China and the United States heavily investing in wind, hydro, solar and biofuels.[52] Renewable energy resources exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries. Rapid deployment of renewable energy and energy efficiency is resulting in significant energy security, climate change mitigation, and economic benefits.[53] In international public opinion surveys there is strong support for promoting renewable sources such as solar power and wind power.[54] At the national level, at least 30 nations around the world already have renewable energy contributing more than 20 percent of energy supply. National renewable energy markets are projected to continue to grow strongly in the coming decade and beyond.[55]

text: The following table shows increasing nameplate capacity, and has capacity factors that range from 11% for solar, to 40% for hydropower.[56]

text: From 2000 to 2013 the total renewable energy use has increased 6,450 TWh and total energy use 40,500 TWh.

text: Hydro[edit]

text: Hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the kinetic energy of falling or flowing water. In 2015 hydropower generated 16.6% of the world's total electricity and 70% of all renewable electricity,[64] which continues the rapid rate of increase experienced between 2003 and 2009.[65] Hydropower is produced in 150 countries, with the Asia-Pacific region generating 32 percent of global hydropower in 2010. China is the largest hydroelectricity producer, with 2,600 PJ (721 TWh) of production in 2010, representing around 17% of domestic electricity use. There are now three hydroelectricity plants larger than 10 GW: the Three Gorges Dam in China, Itaipu Dam in Brazil, and Guri Dam in Venezuela.[65] Nine of the worlds top 10 renewable electricity producers are primarily hydroelectric, one is wind.

text: Marine energy[edit]

text: Marine energy, also known as ocean energy and marine and hydrokinetic energy (MHK) includes tidal and wave power and is a relatively new sector of renewable energy, with most projects still in the pilot phase, but the theoretical potential is equivalent to 4–18 million tonne of oil equivalent (toe). MHK development in U.S. and international waters includes projects using devices such as, wave energy converters in open coastal areas with significant waves, tidal turbines placed in coastal and estuarine areas, in-stream turbines in fast-moving rivers, ocean current turbines in areas of strong marine currents, and ocean thermal energy converters in deep tropical waters.[66]

text: Wind[edit]

text: Wind power is growing at the rate of 17% annually, with a worldwide installed capacity of 432,883 megawatts (MW) at the end of 2015,[67][68][69] and is widely used in Europe, Asia, and the United States.[70][71] Several countries have achieved relatively high levels of wind power penetration, such as 21% of stationary electricity production in Denmark,[72] 18% in Portugal,[72] 16% in Spain,[72] 14% in Ireland[73] and 9% in Germany in 2010.[72][74] As of 2011, 83 countries around the world are using wind power on a commercial basis.[74] Continuing strong growth, by 2016 wind generated 3% of global power annually.[75]

text: Solar[edit]

text: Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating, solar photovoltaics, concentrated solar power and solar architecture, which can make considerable contributions to solving some of the most urgent problems the world now faces. The International Energy Agency projected that solar power could provide "a third of the global final energy demand after 2060, while CO2 emissions would be reduced to very low levels."[76] Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic systems and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air. From 2012 to 2016 solar capacity tripled and now provides 1.3% of global energy.[77]

text: Geothermal[edit]

text: Geothermal energy is used commercially in over 70 countries.[78] In 2004, 200 petajoules (56 TWh) of electricity was generated from geothermal resources, and an additional 270 petajoules (75 TWh) of geothermal energy was used directly, mostly for space heating. In 2007, the world had a global capacity for 7010100000000000000♠10 GW of electricity generation and an additional 7010280000000000000♠28 GW of direct heating, including extraction by geothermal heat pumps.[79][80] Heat pumps are small and widely distributed, so estimates of their total capacity are uncertain and range up to 7011100000000000000♠100 GW.[78]

text: Bio energy[edit]

text: Until the beginning of the nineteenth century biomass was the predominant fuel, today it has only a small share of the overall energy supply. Electricity produced from biomass sources was estimated at 44 GW for 2005. Biomass electricity generation increased by over 100% in Germany, Hungary, the Netherlands, Poland, and Spain. A further 220 GW was used for heating (in 2004), bringing the total energy consumed from biomass to around 264 GW. The use of biomass fires for cooking is excluded.[79] World production of bioethanol increased by 8% in 2005 to reach 33 gigalitres (8.7×109 US gal), with most of the increase in the United States, bringing it level to the levels of consumption in Brazil.[79] Biodiesel increased by 85% to 3.9 gigalitres (1.0×109 US gal), making it the fastest growing renewable energy source in 2005. Over 50% is produced in Germany.[79]

text: By country[edit]

text: World total final consumption of 13,699 Mtoe by region in 2014 (IEA, 2016)[13]

text: Energy consumption is loosely correlated with gross national product and climate, but there is a large difference even between the most highly developed countries, such as Japan and Germany with an energy consumption rate of 6 kW per person and the United States with an energy consumption rate of 11.4 kW per person. In developing countries, particularly those that are sub-tropical or tropical such as India, the per person energy use rate is closer to 0.7 kW. Bangladesh has the lowest consumption rate with 0.2 kW per person.

text: The US consumes 25% of the world's energy with a share of global GDP at 22% and a share of the world population at 4.59%.[81] The most significant growth of energy consumption is currently taking place in China, which has been growing at 5.5% per year over the last 25 years. Its population of 1.3 billion people (19.6% of the world population[81]) is consuming energy at a rate of 1.6 kW per person.

text: One measurement of efficiency is energy intensity. This is a measure of the amount of energy it takes a country to produce a dollar of gross domestic product.

text: Oil[edit]

text: Saudi Arabia, Russia and the United States accounted for 34% of oil production in 2011. Saudi Arabia, Russia and Nigeria accounted for 36% of oil export in 2011.

text: The table to the right shows the amounts of energy consumed worldwide in 2012 by four sectors, according to the Energy Information Administration of the US Department of Energy:

text:
Residential (heating, lighting, and appliances)
Commercial (lighting, heating and cooling of commercial buildings, and provision of water and sewer services)
Industrial users (agriculture, mining, manufacturing, and construction)
Transportation (passenger, freight, and pipeline)

text: Of the total 120 PWh (7020432000000000000♠120×1015 Wh) consumed, 19.4 were in the form of electricity, but this electricity required 61.7 PWh to produce. Thus the total energy consumption was around 160 PWh (ca 7020580280718941000♠550×1015 Btu).[86] The efficiency of a typical existing power plant is around 38%.[87] The new generation of gas-fired plants reaches a substantially higher efficiency of 55%. Coal is the most common fuel for the world's electricity plants.[88]

text: Another report gives different values for the sectors, apparently due to different definitions. According to this, total world energy use per sector in 2008 was industry 28%, transport 27% and residential and service 36%. Division was about the same in the year 2000.[89]

text: European Union[edit]

text: The European Environmental Agency (EEA) measures final energy consumption (does not include energy used in production and lost in transportation) and finds that the transport sector is responsible for 31.8% of final energy consumption, households 26.2%, industry 25.6%, services 13.5% and agriculture 2.9% in 2012.[90] The use of energy is responsible for the majority of greenhouse gas emissions (79%), with the energy sector representing 31%, transport 19%, industry 13%, households 9% and others 7%.[91]

text: While efficient energy use and resource efficiency are growing as public policy issues, more than 70% of coal plants in the European Union are more than 20 years old and operate at an efficiency level of between 32–40%.[92] Technological developments in the 1990s have allowed efficiencies in the range of 40–45% at newer plants.[92] However, according to an impact assessment by the European Commission, this is still below the best available technological (BAT) efficiency levels of 46–49%.[92] With gas-fired power plants the average efficiency is 52% compared to 58–59% with best available technology (BAT), and gas and oil boiler plants operate at average 36% efficiency (BAT delivers 47%).[92] According to that same impact assessment by the European Commission, raising the efficiency of all new plants and the majority of existing plants, through the setting of authorisation and permit conditions, to an average generation efficiency of 51.5% in 2020 would lead to a reduction in annual consumption of 15 km3 (3.6 cu mi) of natural gas and 25 Mt (25,000,000 long tons; 28,000,000 short tons) of coal.[92]
