Electric vehicles convert up to 62% of the electrical energy from the grid to power at the wheels. Very little is wasted as heat. I took this picture after a one hour drive during a snow storm here in Ottawa. The snow that fell on the hood didn’t melt. It looks like I was just park outside.
Most people don’t realize this but about 80% of the money you spend on gas is actually lost/wasted by your car engine. Internal combustion engines are very inefficient at converting the fuel’s chemical energy to mechanical energy, losing most of it to engine friction, pumping air into and out of the engine, and wasted heat. You’re basically buying gas to warm up the hood of your car.
