Calculate how much a source of energy can cost you. The chart below puts the common home heating fuels on one scale - fuel oil, propane, natural gas, electricity, coal, firewood, wood pellets and shelled corn - by working each one back to a cost per million BTU, which is the only figure that compares a gallon with a cord with a kilowatt-hour.
The unit prices in it are examples, not quotes. Fuel prices move and appliance efficiencies differ, so read the right-hand column against the prices you actually pay. If you would like help working out what a particular stove, insert or fireplace would cost to run in your home, ask us.
