Document Summary
Something that is burned to provide heat. Hydroelectric power (not related to hydrogen power) Electricity and hydrogen are not energy sources. Something from a long time ago that decomposed. From high pressure and temperature of soil layers. Always extracted from ground by digging holes. Natural gas, coal, petroleum, petroleum is king. Nonrenewable resources take up 90% of our fuel supply. Natural gas consumption is increasing because of fracking. 1 quadrillion btu (british thermal unit) is consumed, 80% is fossil fuels. Used for residential, commercial, industrial, and transportation. 40% of fuel is used to produce electricity. 91% of coal is used for electricity. 93% of transportation is supported by petroleum. We are decreasing coal and increasing natural gas. We have a lot (150-250 years worth), most abundant. Extracting process starts with the easiest to get, we now have to dig deeper to. In contrast, france"s main electricity source is from nuclear get less efficient coal.
