State Profiles and Energy Estimates

Changes to the State Energy Data System (SEDS) Notice: In October 2023, we updated the way we calculate primary energy consumption of electricity generation from noncombustible renewable energy sources (solar, wind, hydroelectric, and geothermal). Visit our Changes to 1960—2022 conversion factor for renewable energy page to learn more.

About SEDS

The State Energy Data System (SEDS) is the source of the U.S. Energy Information Administration's (EIA) comprehensive state energy statistics. EIA's goal in maintaining SEDS is to create historical time series of energy production, consumption, prices, and expenditures by state that are defined as consistently as possible over time and across sectors for analysis and forecasting purposes.

Dimensions of SEDS estimates

Consumption

  • by state and for the United States
  • by energy source
  • by sector
  • in physical units and Btu
  • annual time-series back to 1960

Prices & expenditures

  • by state and for the United States
  • by energy source
  • by sector
  • prices in current dollars per million Btu and expenditures in current dollars
  • annual time-series back to 1970

Production

  • by state and for the United States
  • by primary energy source
  • in physical units and Btu
  • annual time-series back to 1960

While some SEDS data series come directly from surveys conducted by EIA, many are estimated using other available information. These estimations are necessary for the compilation of "total energy" estimates. The data sources and estimation procedures are described in the technical notes. We welcome your suggestions on ways to improve our estimation methodologies.
