where does most of us electricity come from
fossil fuels
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 sector of the United States text: electric utilities in the United States and 65 power marketers. Of these, 2,020 were publicly owned (including 10 Federal utilities), 932 were rural electric cooperatives, and 243 were investor-owned utilities. Fewer than 1,000 utilities are engaged in power generation. About 80% of the electricity in the U.S. is generated by private ("investor-owned") utilities. The remaining electricity is produced by the public sector. This includes federal agencies such as the Tennessee Valley Authority (producing mainly nuclear and hydropower), and Power Marketing Administrations of the Department of Energy, one of which is the Bonneville Power Administration (in the Pacific Northwest)(hydropower). It also 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 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 sector of the United States text: 2015. The USA also imported 69.60 Terawatt hours and exported 9.33 Terawatt hours: making a total of 4137.1 Terawatt hours for consumption, down 7.2 TWh from 2015. Electricity generation was primarily from the following sources: The share of coal and nuclear in power generation is much higher than their share in installed capacity, because coal and nuclear plants provide base load and thus are running longer hours than natural gas and petroleum plants which typically provide peak load, while wind turbines and solar plants produce electricity when they can and natural gas fills in as required to compensate. The following
