But you do have to remember as well that a gas engine is maybe 15% efficient turning the gas energy into go. An electric motor for a car would be around 90% efficient. So a trip in a gas car that requires a gallon of gas, only takes 5 to 6 KWhrs of electricity.
From an environmental aspect, a power station is only 35-40% efficient at burning coal. Transmission losses of around 10%, whatever charging losses are into the battery etc. etc.
Environmentally, it doesn't make a whole lot of sense for a large part of the world.
Cost wise, power for all WILL go up as any excess in the grid will be rapidly consumed, and new plant (and environmental damage) will have to come on line.
First will be the 23% efficient gas peaking plant.
