Thank you for proving the electric automobile is a better use of energy.

You are probably aghast that 50% of the energy generated is lost. Bad
as it seem, that is much better than the internal combustion engine.

How efficient is an internal combustion engine?
20 percent
Most internal combustion engines are only 20 percent thermally
efficient, according to Green Car Reports. In addition to heat, the
various systems required to run the engine all take energy that could
potentially be put to use propelling the vehicle.Mar 1, 2018

Toyota has done better, but still not as good as an EV. Don't forget
the cost of energy to transport gas to the local stations.
