Statistical Highlights

EEI maintains comprehensive statistical data on the electric power industry and investor-owned electric companies. Below are quick statistical highlights providing an overview of the industry. For more detailed information, see Products and Services.


Forecast Data

  • Total electric industry capability in the United States is forecast by the Energy Information Administration to increase a total of 29.3% from 2014 through 2040.  Coal capability is expected to decrease over 14%, retiring over 50 gigawatts of capability, within the total electric power sector.  Renewable sources increase their capability by almost 45% over the period.
  • Total retail sales are forecast to increase 25.4% from 2013 through 2040.  Those generating electricity for their own use is expected to more than double over the same period. 


  • The U.S. electric power industry's total installed generating capacity was 1,172,604  megawatts (MW) as of December 31, 2012—a 1.0-percent increase from 2011.
  • U.S. investor-owned installed generating capacity was 420,296  MW as of December 31, 2012. This accounts for approximately 36 percent of total electric power industry installed capacity. 
  • Non-utility owned installed generating capacity grew from 487,002  MW in 2011 to 494,684 in 2012.


  • In 2012, total U.S. electricity generation was 4,047,765 gigawatt-hours (GWh)—a 1.3 percent decrease from 2011.  
  • U.S. investor-owned electric companies accounted for 1,478,887 GWh, or 46.3 percent, of total U.S. electricity generation. 
  • Electricity generation at non-utility-owned plants totaled 1,675,295 GWh and accounted for 32.2 percent of the total electricity generation in the United States.

Fuel Mix

2015 National Fuel Mix
  • Coal provided 34.0 percent of our nation's electricity.
  • Natural gas supplied 32.5 percent. 
  • Nuclear energy produced 19.4 percent.
  • Hydropower provided 5.9 percent of the supply.
  • Other renewable resources, such as geothermal, solar, and wind, provided 7.1 percent.
  • Fuel oil provided 0.7 percent of the generation mix.
  • Other miscellaneous sources provided 0.5 percent.
  • Learn more about these diverse fuels.

Emission Reductions

  • As of the end of 2014, electric power sector CO2 emissions had declined 15 percent from 2005 levels, driven in part by low natural gas prices, increased deployment of renewable generation and low load growth.
  • Since 1990, the industry has cut sulfur dioxide (SO2) emissions by 86 percent and nitrogen oxides (NOx) emissions by 79 percent.
  • EPA projects that power sector mercury emissions will be reduced by approximately 90 percent due to its Mercury and Air Toxics Standards (MATS) and other Clean Air Act regulations.
