According to figures released by the U.S. Energy Information Administration on 24th of June, 2011, last year US oil refineries purchased 46,227 million Kilowatt-hours from electricity companies in the USA.
Assuming that a) in the US 43% of oil is used for cars (the figure most often quoted on the internet forums) and b) a Nissan Leaf does 3.4 miles per kWh, and c) an electric car travels on average 10,000 miles per year, then the electricity alone used just to refine the oil for use in conventional cars is sufficient to power nearly 7m electric cars, or more than half of the new cars sold each year in the US.
Can this be true????
