Quick Facts

  • Although the District of Columbia uses less total energy than any state but Vermont, its energy use per capita is greater than almost one-third of the states.
  • The District of Columbia leads all U.S. cities in the number of Energy Star-certified buildings, surpassing the much larger city of Los Angeles, California for the first time in 2014. 
  • One of the largest solar energy installations in Washington, DC, is located on the roof of the U.S. Department of Energy’s Forrestal headquarters building. The installation generates about 230,000 kilowatthours of electricity per year.
  • In 2015, 73% of retail electricity sales in the District of Columbia went to the commercial sector, and only 2% went to the industrial sector, reflecting the District of Columbia's large concentration of government buildings and museums as well as government-related activity.
  • The District of Columbia has adopted a renewable portfolio standard (RPS) requiring that 50% of its electricity come from renewable sources by 2032, including at least 5% from solar energy. Only four states have set higher RPS requirements.
