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 %, which was mainly from hydroelectric dams and biomass but also included other renewable sources such as wind power, geothermal and solar energy. 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.
