I have always marveled at the thinking that to get rid of oil use, we go to electric which is made by the use of oil. Now if you want to make electricity from Nukes and then charge up your car, that makes sense.
Very little electricity is made from oil. Much of the petroleum that is used is petroleum coke and residual oil. These are refinery "leftovers" after the gasoline, diesel and other fuels are removed from the crude oil.
