Any kid who took a high school class in physics could easily answer that question. Did you take any physics in school?

Tell you what. I'll help you out. Let's take a "state of the art" condensing NG furnace that's input BTU's is 100,000 with a typical efficiency of 95%. I'll eliminate the fan motor used to reject the heat from the heat exchanger so the actual output heat is 100,000 x0.95 = 95,000 BTU's of heat delivered to the house. Now take a very efficient combined cycle NG fired power plant at about 60% in the conversion process to electrical power. My heat pump has a COP of 3.5 at 47 degrees F OAT (outside air temp). So if I took the electrons from that NG fired combined cycle power plant the numbers would be this. 0.60 X 3.5 = 2.1 I'm achieving roughly 200,000 BTU's of effective heating out of the same 100,000 BTU's being burned by that NG fired furnace in the house. Now I didn't include the electric fan motor on the outside compressor (heat pump) unit and the electric motor in the inside the house air handler. Virtually twice the heat Now I get my electrons from a couple of different sources. My hydropower is dirt cheap. Much cheaper than NG. Or the Sun direct to PV's. NG loses every time.
