The prices we publish on our website are generally nominal prices, or prices that we have not adjusted for inflation. In some cases, we publish inflation-adjusted prices, which are called real prices. Unless otherwise noted, our published prices are nominal prices.
We have 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, residential electricity, and residential natural gas. The Price series drop-down field of the Real Prices Viewer will sort for a variety of fuels and electricity.
