China and Europe are ahead of the curve in electric vehicle production and adoption, but Tesla, GM and Nissan are already selling electric cars in the US, and almost all major automakers have announced plans to begin producing them as well: even Ford has announced a Mustang EV. However, even if all the power in the world was generated by burning coal, the fact is that industrial power plants are much more efficient at converging fossil fuels into energy than car engines. Assuming that the cost of solar cells and batteries keeps falling, we will soon reach a point where renewable energy is available 24 hours a day, and cheaper than fossil fuels.
