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]
Electricity sector in Canada Hydroelectricity accounted for 58% of all electric generation in Canada in 2007,[2][3] making Canada the world's second-largest producer of hydroelectricity after China.[4] Since 1960, large hydroelectric projects, especially in Quebec, British Columbia, Manitoba and Newfoundland and Labrador, have significantly increased the country's generation capacity. Canada is the world's sixth-largest producer of electricity generated by nuclear power, producing 97 billion kWh in 2013.[5] In Ontario, Canadian-designed CANDU nuclear reactors supplied more than half the provincial electricity demand in 2007.[3] In April 2014, Ontario became the first jurisdiction in North America to fully eliminate coal as a source of electricity generation.[6][7]
