There are several ways to produce electrical energy. The highly efficient ones are not practical to drive an electric vehicle future. Example nuclear, hydro, solar, and wind.
The ones that do produce a majority of our energy have an 18-22% conversion rate on btu:btu exchange.
So if I put 1,000,000 bits of energy in i can get rough 180,000 to 220,000 btu's of energy back in electricity.
North America has the largest oil reserve in the world in the Oil Sands. It makes the Saudi's look meek. There may be over 200 years reserve or more. The conversion rates on petroleum are very high over compared to electrical generation worldwide.
EV is exciting, but wasting oil reserves being a knucklehead Starbucks latte generation dreaming this is the future is foolish.
What do you think is going to happen in the world economy after the President rebuilds the world's strongest military, controls world gd&p, and takes away the Saudi's reign in world market manipulations?
The new CEO of GM will be pushing a race to 70 mpg internal combustion with large torque ratios. Ps I don't think the CEO's name will be Marry, it will most likely be Mark.
Wise words to think about, "Don't take your eye off the ball."
