Dear David,
Here's a way to calculate the costs:
For LP gas (93,000Btu/Gal.) @75% efficiency $/MBtu=14.3 x $/Gal. ; @ 95%
efficiency, $/MBtu = 11.3 x $/Gal.
For #2 Fuel Oil (138,000 Btu/Gal.) @ 65% efficiency $/MBtu = 11.1 x $/Gal. ;
@ 85% efficiency $/MBtu = 8.5 x $/Gal.
For electricity (3412 Btu/KWH) @ "100%" efficiency (electric resistance
heat) $/MBtu = 293 x $/KWH
(Sorry to oue overseas friends for the crazy English units, instead of your
sensible Metric.)
You'll see that generally, #2 oil will be the least cost per Btu and
electricity the most. That's monetary price, not necessarily full social
and environmental price.
Hope this helps. Cheers - David Foley
