A. Unfortunately there is no such thing as a zero emission car...
B. Moving the exhaust from the car tail pipe - to the power plant, does not solve the problem.
The power plant runs on fossil fuels.

Until all power is generated from non fuel sources, the problem still exists.
C. There has been a slight miscalculation:
Between the power plant and the point of usage, 63% of the power is lost (as heat) in the power grid.
In other words, if you generate 100 KWH of power, only 47% of it reaches the electric car charger.
63 KWH of the power is lost in the wires between the power plant and the car.
People assume that electricity is 100% efficient, it's far from it.
This small error / miscalculation reveals that electric cars are no more efficient than gasoline cars.

But there is hope:
if you can generate all electricity from non fuel sources.
Now we shall see
if my plan to generate electricity from the magnetic field of the earth will work....
(geomagnetic energy) if so, problem solved.
