Unless otherwise indicated, the prices published on the website of the U.S. Energy Information Administration (EIA) are nominal prices or prices that have not been adjusted to remove the effect of changes in the purchasing power of the U.S. dollar. Prices that are adjusted for changes in the purchasing power of the U.S. dollar are identified as real prices.
EIA has a Real Prices Viewer that provides average annual, monthly, and quarterly real prices for imported crude oil, retail regular grade gasoline, retail diesel fuel, retail heating oil, and residential electricity and residential natural gas. Use the Price Series drop-down field of the Real Prices Viewer to select for those fuels and electricity.
