A Bathtub of Water

Natural Gas

Electric Resistance

Electric Heat Pump

Since renewables are not time-dispatchable, much of the "electric" power will be gas-powered anyway, and electric generation efficiency is much less than direct heating efficiency. The environmental cost of intermittent renewables is similar to the direct use of the gas used when the renewable sources are absent. Nuclear power would be far cleaner environmentally and much safer than gas, but politically impossible with a media-stupified electorate.
