I think my knee jerk reaction was to agree with redneck, but then I was thinking that block heaters were close to even money. If a gallon of gas is worth 33.7kwh, and avg cost per kWh in the U.S. is $0.12, then it's like paying $4.04 for a gallon of electricity. So I figured the savings were in how inefficiently cars turn gas into electricity, but I don't know what the numbers are for that. can anyone fill in on the rest of the math?
