U.S. electricity generation by energy source

What is U.S. electricity generation by energy source?

In 2016, about 4.08 trillion kilowatthours (kWh) of electricity¹ were generated at utility-scale facilities in the United States.²  About 65% of this electricity generation was from fossil fuels (coal, natural gas, petroleum, and other gases), about 20% was from nuclear energy, and about 15% was from renewable energy sources. The U.S. Energy Information Administration (EIA) estimates that an additional 19 billion kWh (or about 0.02 trillion kWh) of electricity generation was from small-scale solar photovoltaic systems in 2016.³

• Natural gas = 33.8%
• Coal = 30.4%
• Nuclear = 19.7%
• Renewables (total) = 14.9%
  • Hydropower = 6.5%
  • Wind = 5.6%
  • Biomass = 1.5%
  • Solar  = 0.9%
  • Geothermal = 0.4%
• Petroleum = 0.6%
• Other gases = 0.3%
• Other nonrenewable sources = 0.3%
• Pumped storage hydroelectricity = -0.2%⁴
