We still need energy to produce the Electricity and burn fossil fuel to do it. We now incure "Brown-outs" during the summer when people run their Air conditioners and overload the grids. What is going to happen to the supply system when more and more people are charging their vehicle? If the price per kw keeps going up and it will, we may end up paying more to fuel our cars than we do now. True! we get cleaner car exhaust but we still have to use fossil fuel to produce the electricity and the battery disposal is still a problem. Solar power harvested through individual solar panels on each home does show some promise and so does wind power but the technology needs improvements to be practical and again batteries are a problem. Is it possible to convert solar power directly through transformers without using battery storage?
