More efficiently
Actually, less efficiently. Every time energy changes form, there are losses. Converting fossil fuel to heat to electricity to chemical energy back to electricity to a magnetic field - to power an electric car has a lot of efficiency losses.
And you're talking sh#t, there are plenty of peer reviewed articles that state that the electric car is more energy efficient and is better for the world than any ICE. Not as green as some people think but still a lot better than what we have now.
Sure if you exclude the non recyclable giant batteries use metals that detroy the planet when mined. So great. Would be better for the world if you would read both sides of the argument. And here is something else forget about cars all together. Cargo ships pollute about 100.000.000 more then all cars and planes combined.
think about how the batteries are made and where the metals come from....
