Thanks, that's some good info. 10kWh × 165M on the night grid, that's big impact. I went and got the miles travelled per year and the total nr of vehicles, you are not far off. although we are forgetting that most traffic is during weekdays, and the size of the cars varies (and with it the usage) For convenience I don't do anything with the size of the cars. "According to the Bureau of Transportation Statistics for 2012, there were 254,639,386 registered vehicles. Of these, 183,171,882 were classified as "Light duty vehicle, short wheel base", while another 50,588,676 were listed as "Light duty vehicle, long wheel base". Another 8,190,286 were classified as vehicles with two axles and six or more tires and 2,469,094 were classified as "Truck, combination". There were 8,454,939 motorcycles also listed along with 764,509 buses." https://en.wikipedia.org/wiki/Passenger_vehicles_in_the_United_States#Total_number_of_vehicles https://en.wikipedia.org/wiki/Passenger_vehicles_in_the_Unit... 250m vehicles in us, if 150m of those are electrical at some point, and the number of miles driven total might be 3.5T miles by then (3.5×0.6=2.1T) 2.1/150m/313×1.6 (6 days of driving a week, and miles to km) comes to 71 km per day, which is 14 kWh (6/7 days) of required draw. I think it is manageable like you said, considering that it will take a while.
