what is the largest source of energy in the united states
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]
United States The United States is the world's oldest surviving federation. The federal republic  is a representative democracy, "in which majority rule is tempered by minority rights protected by law".[28] The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States (OAS), and other international organizations. The United States is a highly developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for approximately a quarter of global GDP.[29] The U.S. economy is largely post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world.[30] The United States is the world's largest importer and the second largest exporter of goods, by value.[31][32] Although its population is only 4.3% of the world total,[33] the U.S. holds 33% of the total wealth in the world, the largest share of global wealth concentrated in a single country.[34] The United States ranks among the highest nations in several measures of socioeconomic performance, including average wage,[35] human development, per capita GDP, and productivity per person.[36] The United States is the foremost military power in the world, making up a third of global military spending,[37] and is a leading political, cultural, and scientific force internationally.[38]
