Of course, we would also need to consume an equivalent amount of fuel, to produce power for electric vehicles. Assuming 117% of our current electrical consumption, and based on our current fuel mixture, we would need to burn about 94 million tons of coal, 2.9 million barrels of petroleum coke, and 826 billion cubic feet of natural gas per month, to provide power for the vehicles. I will calculate the related CO2 emissions and costs later.
Critics have commented that charging vehicles could be accomplished overnight, during non-peaking hours. This is true. Still the magnitude of the required power, and the additional fuel consumption regardless of when vehicles are being charged, make the challenge of powering a fleet of electric vehicles truly daunting.
