Now, if we're comparing heat strips, to oil or propane, now the energy costs are more comparable. But then again, if your a tree hugger, since 75% of our electricity comes form fossile fuel, you want to reduce CO2 emmission, you want to use gas and oil as mcuh as possible. 80-98% efficiency when heating form those. A power plant might be 95% efficient thermally, but needs electricity to operate it's own pumps, fans, lights, etc. SO subtract all that plus the effciency of the generator and transmission, and only about I think 25-30% of the energy in fossil fuels makes it to a home. So you need a COP of maybe 4 to break even with a HE natural gas furnace.
95% is absurd

actual efficiency of 42% for a modern coal-fired power station.

... NuClear station = 36%
