13. Coal is our most abundant fossil fuel. US has a 250 yr. supply Primarily used for generating electricity.
14. How is electricity generated from coal? Coal is burned to heat water to make steam High pressure steam turns the turbines The turbine spins the generator , which produces an electrical current

Oliva -- a Maltese-registered ship -- ran aground, fracturing its hull and ultimately splitting the vessel in two. The islands' conservation director said at least 300 penguins have died after a cargo ship leaked thousands of tons of heavy oil near Nightingale Island, a British territory part of the Tristan da Cunha archipelago.Thousands more are covered in the ships' oil and diesel fuel, according to local officials and conservationists.

33. 1 April 2010 Obama Oil Drilling Plan Draws Critics President Obama ’s proposal to open vast expanses of American coastlines to oil and natural gas drilling drew criticism from both sides in the drilling debate. The plan, which Mr. Obama said would balance the need to produce more domestic energy while protecting natural resources, would allow drilling along the Atlantic coastline, the eastern Gulf of Mexico and the north coast of Alaska. It would end a longstanding moratorium on exploration from the northern tip of Delaware to the central coast of Florida, covering 167 million acres of ocean. “ Drilling our coasts will do nothing to lower gas prices or create energy independence,” Michael Brune, executive director of the Sierra Club, said in a statement. It will only jeopardize beaches, marine life, and coastal tourist economies, all so the oil industry can make a short-term profit.”
34. Public supports energy over environment Apr 6, 2010 WASHINGTON (Reuters) - For the first time in 10 years Americans are more likely to say the United States should give more priority to developing oil, natural gas and coal than to protecting the environment, according to a poll on Tuesday. Half of 1,014 U.S. adults, who were surveyed March 4-7 by Gallup, said the country should give more priority to developing and producing the fossil fuels. Only 43 percent said protection of the environment should be given priority, even at the risk of limiting the amount of energy supplies. It was the first time in the 10 years that Gallup has been asking the question that energy production was favored over environment.

37. But it is also has oil and natural gas Current political debate over whether or not to allow drilling
38. The total quantity of recoverable oil within the entire assessment area is estimated to be between 5.7 and 16 billion barrels (numbers vary depending on who is reporting them) Peak production from ANWR could to be between 1 and 1.3 million barrels a day
39. “ ANWR production could equal 46 years of current oil imports from Iraq.” D.Cheney But what does that statistic really mean given that we don ’t get much oil from Iraq?
40. So, if the US were to get all of its oil from ANWR, it would last a little longer than 6 months (exact number depends on which estimates of supply and use are used). Some opposed to drilling have claimed that ANWR only has 6 months worth of oil 4.5 billion barrels recovered from ANWR / 24 million barrels per day used in US = 187.5 days But, it can ’t be pumped that fast, and we will never get all of our oil from ANWR
41. 1/24 = about 4% of our oil needs Better calculation: Peak production from ANWR could to be between 1 and 1.3 million barrels a day But it will take at least 10 years to reach the market By that time, it is predicted we will be using ~ 24 million barrels/ day
42. How much oil will be pumped depends not only on how much is there, but on current crude oil prices Profits for oil industry have to exceed their costs USGS estimate: 95% chance of producing 2 billion barrels 50% chance of producing 4.5 billion barrels 5% chance of producing 9 billion barrels But, will ANWR reach maximum production?
43. Environmental Impacts Roads will be constructed of ice, which can alter availability of freshwater for animals Noise, pollution and construction will impact wildlife and destroy habitat At other Arctic drilling sites, crews dump garbage, sewage and toxic waste Oil spills
44. How can we reduce our dependence on foreign oil? One suggestion: Increase our own oil production from our known reserves
45. If the average fuel efficiency of cars and light trucks were improved by ONE mile per gallon it would save more oil than is likely ever to be recovered from ANWR Ford Model T in 1908 – 20-25 mpg Current Corporate Average Fuel Economy (CAFE) standards: Cars - 27.5 mpg Light trucks (includes vans and most SUVs) – 20.7mpg Another suggestion…
46. Fuel-Economy Rules Set EPA Climate-Change Standard April 01, 2010 The Obama administration set the first national regulations targeting climate change, boosting U.S. automobile fuel-economy standards by about 30 percent. The requirements were raised to an average of 35.5 miles per gallon for 2016 model-year cars and light trucks from 27.3 mpg in 2011. The final rule issued today will cost automakers $52 billion to comply and add $926 to the cost of buying a car within five years, according to government estimates. “ This is a significant step,” Environmental Protection Agency Administrator Lisa Jackson said in a joint statement with Transportation Secretary Ray LaHood. “Our economic and environmental priorities go hand-in-hand.”
