yeah but I see that a bit of a fools proposition.

1) there is a lot of electricity that is from green sources and that means that it is wasted when it is not needed but can be produced since there is no human control on the elements. For example a hydro electric dam can't decide to leave a lot more water than makes sense out (to make more electricity) because it might flood areas downriver, on the other hand if electricity is not needed they can't go past a point of closing the gates) because they still need to let the amount of water that makes sense for the river past that point as well as it might flood what is up river. The same with wind ( how many windmills you build is important but you can't control if the wind is blowing hard but the electricity is not needed.

2) none green power plants that use none renewable resources are much more efficient than a car engine and a lot cleaner too. So even if we forget about # 1 and assume that all the extra power needed is an extra draw on these bad power plants, it will still be better. To make it simple, let's take an example where a car gets X miles to a gallon, if I we replace it with a power plant that makes W Watts to the gallon and an electric car that does M miles to the Watt for that one gallon used by the plant to make electricity the electric car will go more miles. Second that plant that uses gas will have a chimney so the exhaust will be higher and not at the height were it is bad for peoples health, and due to stricter regulations that exhaust of the plant will be cleaner than the exhaust of that car for the same number of gallons of gas used.

(also there is a reason that gas (or as said in this report liquid petroleum) is one of the least used sources for power plants. It makes sense for cars since it is easily transportable and used but not as good as other none renewable sources at keeping a motor running at a cost)
