where do we get most of our electricity energy from

title: Electricity sector of the United States text: Commission. Economic regulation of the distribution segment is a state responsibility, usually carried out through Public Utilities Commissions; the inter-state transmission segment is regulated by the federal government through the Federal Energy Regulatory Commission. Principal sources of US electricity in 2014 were: coal (39%), natural gas (27%), nuclear (19%), Hydro (6%), and other renewables (7%). Over the decade 2004—2014, the largest increases in electrical generation came from natural gas (2014 generation was 412 billion kWh greater than 2004), wind (increase of 168 billion kWh) and solar (increased 18 billion kWh). Over the same decade, annual generation from coal decreased 393 title: Electricity generation text: plants. The in-house consumption of electricity and power transmission losses were 289,681 ktoe. The amount supplied to the final consumer was 1,445,285 ktoe (16,430 TWh) which was 33% of the total energy consumed at power plants and heat and power co-generation (CHP) plants. The United States has long been the largest producer and consumer of electricity, with a global share in 2005 of at least 25%, followed by China, Japan, Russia, and India. As of Jan-2010, total electricity generation for the two largest generators was as follows: USA: 3,992 billion kWh (3,992 TWh); China: 3,715 billion kWh (3,715 TWh). Data title: Electricity generation text: 25,082TWh. Sources of electricity were coal and peat 38.3%, natural gas 23.1%, hydroelectric 16.6%, nuclear power 10.4%, oil 3.7%, solar/wind/geothermal/tidal/other 5.6%, biomass and waste 2.3%. Total energy consumed at all power plants for the generation of electricity was 4,398,768 ktoe (kilo ton of oil equivalent) which was 36% of the total for primary energy sources (TPES) of 2008. <br> Electricity output (gross) was 1,735,579 ktoe (20,185 TWh), efficiency was 39%, and the balance of 61% was generated heat. A small part (145,141 ktoe, which was 3% of the input total) of the heat was utilized at co-generation heat and power title: World energy consumption text: an unknown amount of heat and electricity consumed off-grid by isolated villages and industries. In 2014, the share of world energy consumption for electricity generation by source was coal at 40.8%, natural gas at 21.6%, nuclear at 10.6%, hydro at 16.4%, other sources (solar, wind, geothermal, biomass, etc.) at 6.3% and oil at 4.3%. Coal and natural gas were the most used energy fuels for generating electricity. The world's electricity consumption was 18,608 TWh 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 title: Electricity sector of the United States text: table summarize the electrical energy generated by fuel sources for the USA. Data was mined from Electric Power Annual 2016]. Profile data is from Electric Power Monthly and is for 2016]. Fossil fuels – mainly coal and natural gas – remain the backbone of electricity generation in the U.S., accounting for 68% of installed generation capacity in 2010. In 2007 the Department of Energy estimated the planned additional capacity for 2008-12 at 92 GW, most of which to be fueled by natural gas (48 GW) and coal (19GW). As of 2007 in the United States, there are 104 commercial nuclear
