Notes: Renewable energy refers to energy derived from the following sources: conventional hydroelectric power, geothermal power, biofuels, solar energy, and wind energy. Hydroelectricity generated by pumped storage is not included in renewable energy estimates. Conventional hydroelectric power includes electricity net imports from Canada that are derived from hydroelectric energy. Geothermal power includes electricity imports from Mexico that are derived from geothermal energy. Geothermal includes only grid-connected electricity; excludes shaft power and remote electrical power. Biofuels are wood, wood waste, peat, wood sludge, municipal solid waste, agricultural waste, straw, tires, landfill gases, fish oil, and/or other waste, and ethanol blended into motor gasoline. Solar energy includes photovoltaic energy. Wind energy includes only grid-connected electricity; excludes direct heat applications. Previous-year data may have been revised. Current-year data are preliminary and may be revised in future publications.
