"However, the internal combustion engine powered automobiles are to be replaced with electric cars. These, too, require energy. The same amount as the conventional cars, to be sure."

I have not done an analysis, but the above statement is simply untrue.

There is a significant amount of energy recovered when an electric motor operates as a generator to slow down and stop the vehicle. This is an efficiency gained only with electrical drive systems (you can't convert kinetic energy back into gasoline with a piston engine).

.
Yes, but it is limited. You will get back about 30% of what it took to accelerate to the point that you began to decelerate, except that the process ends, and the friction brakes engage at about 8 MPH in mild braking, but at a much higher speed on panic braking.

Also, he was discussing the Volt, which doesn’t work that way.
