where does most of america's energy come from
Energy in the United States The majority of this energy is derived from fossil fuels: in 2010, data showed 25% of the nation's energy came from petroleum, 22% from coal, and 22% from natural gas. Nuclear power supplied 8.4% and renewable energy supplied 8%,[4] which was mainly from hydroelectric dams and biomass but also included other renewable sources such as wind power, geothermal and solar energy.[5] Energy consumption has increased at a faster rate than domestic energy production over the last fifty years in the U.S. (when they were roughly equal). This difference is now largely met through imports.[6]
World energy consumption 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 18,608Â 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.
