Cost of a heating oil or propane delivery (gallons times this week's EIA average for the state, or a given price), the cost per million Btu, and a comparison of heating oil and propane per million Btu at the same area's averages. Optionally add your electricity rate (cents per kWh) or natural gas rate (dollars per therm) to compare. Uses EIA heat contents.
