Though the media enjoys talking at great length about alternative automotive fuels, there is already a plethora of choices for home heating fuels. If you've ever wondered just how these various fuels stack up, I've compiled a quick cheat-sheet which shows each fuel's BTU output. Enjoy!
Pellet: 1 pound = 6500 Btu
Corn: 1 pound = 7000 Btu (@ 15% moisture)
Electric: 1kWh = 3413 Btu
Gas: 1 therm = 100000 Btu
Propane: 1 gallon gas = 91690 Btu (@ 60 degrees F)
Propane: 1 pound gas = 21591 Btu
Fuel Oil 1 gallon oil = 139000 Btu
Using some basic Price assumptions, here's the cost of heating with each fuel
Electric: $2.05 per therm (100,000 Btu) assuming 7 cents per kWh
Electric(2): $0.90 per therm (100,000 Btu) assuming 3 cents per kWh
Gas: $1.20 per therm (100,000 Btu)
Corn: $0.57 per therm (100,000 Btu) assuming 4 cents per lb
Pellet: $1.15 per therm (100,000 Btu) assuming 7.5 cents per lb
Fuel Oil: $1.62 per therm (100,000 Btu) assuming 2.25 per gallon
For all you corn fanatics out there:
1)There are 20 bushels in 1 cubic yard
2)Corn weighs ~56lbs per bushel
3)Corn costs ~$2.35 per bushel
