By the time the electric car boondoggle is realized in these states, you won't be able to power a smart watch over power consumption concerns.
Elec cars require about 30kWh of charge per 100 miles. It takes roughly 1lb of coal to produce 1kWh. So 30lbs of coal for 100 miles in an elec car.
The average vehicle in the US gets 25mpg. 4 gallons to get 100 miles.
Hmmm, 30lbs of coal vs 4 gallons of gasoline (24.4lbs).
Oh, and the average home in the US uses 29kWh of elec per day. (without juicing up an elec car).
Some obvious points you are missing here:
1: You ignore the cost of extracting coal [both the immediate mining cost and the other longer-term costs involved in cleanup, healthcare for miners, and so on]
2: You ignore the energy cost of extracting, transporting, refining, and transporting (again) oil into usable gasoline. I'm reasonably certain that energy cost exceeds 30 Kw/h per 4 gallons.
3: The majority of the grid is ALREADY renewables. And it's holding together fine. Same with countries where upwards of 80% of the grid is renewable.
