Today, I am paying $1.10 per therm for natural gas. This amounts to about 3.75 cents per kWh. I have an older furnace whose efficiency is around 80% increasing the heating cost to 4.7 cents per kWh. Add in the cost of the blower electricity and the gas service charge, and I'm paying over a nickel per kWh to heat my house.
Electric space heaters are 100% efficient. I presently pay about 10 cents per kWh for e-. Rumors abound that natural gas costs will soar this winter. If gas doubles, it's cheaper to use electricity assuming that price remains the same.
