I think power plant thermal efficiency tops out around 32 %.So about 68% of the fuels(whatever fuel they use)energy is lost right at the powerplant.An additional 7% of the electric production is lost within the powerlines according Ohm's Law.They can't boost the voltage and get current down to reduce the loss do to increased EMF caused by high-voltage alternating current,which has been linked to human healthcare issues.If the powerplant WERE burning gasoline,I think it has an average energy content of about 124,000 Btu per gallon.Wind and solar would be the hot ticket!
