The U.S. Department of Energy's Energy Information Administration posts weekly regional propane prices on its website, EIA.gov. The listed prices are for both propane and heating oil. The chart shows propane prices both by general region and individual state.
The Energy Information Administration's price chart expresses the cost of propane and heating oil as the cost of the fuel in dollars per gallon.
In addition to the current week's regional propane prices, the site also provides historical weekly propane prices stretching back to 1990. Users can view the information on the website or use tools on the site to export the data directly to Microsoft Excel or other spreadsheet software for manipulation and analysis.
