The U.S. Energy Information Administration (EIA) provides data on total annual energy production by state in British thermal units (Btu), as well as information on fuel ethanol production (including denaturant, in thousand barrels) and electricity generation (in thousand megawatt-hours, or million kilowatt-hours). Several of these data sets are provided below. Caution should be exercised when comparing electricity generation data from different years because of methodology changes (see https://www.eia.gov/electricity/monthly/pdf/technotes.pdf and https://www.eia.gov/electricity/annual/pdf/tech_notes.pdf).
For more information, please visit EIA’s State Energy Data System and Electricity pages. The American Clean Power Association also provides data on wind, solar and energy storage by state, and the Solar Energy Industries Association provides state-level data on solar capacity installations.
