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, expenditures, and indicators 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
Indicators
- by state and for the United States
- by variable type and input
- annual time-series back to 1960, or as far back as available
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.
