I wish there was a way to search comments.

I don't know if a comment states the efficiencies of gas, diesel and stations power plants. Gas engines are about 25% to 30% efficient, meaning only 1/4 of the energy going into the engines, pushes the car along, 3/4 goes out the tail pipe as heat. Diesels run 30% to 35% efficient, hence they can deliver better mileage. Electric motors run about 95% efficient.

Stationary power plants can optimized for energy and emissions output. Cars and trucks run optimally for a narrow range of speed and load, most of the time they run less than their possible efficiency. Old and primitive thermal power plants probably were about 20% to 25% efficient. Today they will push 40% efficient, maybe 50%. The very very very large marine diesels can run close to 50% when utilizing all the exhaust gas energy recovery systems available.

Electric motors deliver energy more efficiently than internal combustion engines.
