You know how we always here how electric transport is green, I've wondered is it really? The vehicles themselves are none polluting but the power has to come from somewhere. By emmissions what would the tonnage of emmissions from the vehicles, compared to the tonnage of emmissions from a power plant producing the power be. This brings to mind another question, what is the cost, and ecological benfit from of a lot of the green energy solutions if you take into consideration the power, raw material and industrial damages to the enviroment from producing the products to produce the power. Has anyone ever done any non biased research into this?
