The EV Illusion -- This is a good way of explaining it

You're not eliminating emissions, you are just outsourcing them to somewhere else.
Law of the universe states that there is no such thing as free energy. It has to come from somewhere. Hence there is no such thing as perpetual motion. You can recapture some energy yes, we learned this with the first turbo chargers. The machine would use heat from the motor to force more air though the motor. You do get an increase in energy (power) but we can never recapture 100%. Not even close. Regenerative braking on the EV's uses the car's momentum when braking to put a small charge back to the batteries. Its saving something but certainly not free energy. You're just moving some of the energy already spent, back into the batteries.
Energy to charge the batteries has to come from somewhere. Even if it comes from the sun via solar panels, there was already energy used to make the batteries and the panels.
There's no free ride man. This is something socialists, communists or democrats can't comprehend.
