The grid is built to handle peak demand, and electric vehicles will mostly be charged off-peak and in particular overnight when there is substantial surplus capacity on the grid, so the need to increase grid capacity will not be as significant as you might think.
- tialaramex 7y agoPeople tend to assume that 100MWh less energy from oil means 100MWh more electricity for the same transport need, but ICE is horribly inefficient so that's not how it works. Most of the energy in that oil is just wasted, an efficient conversion would be too heavy and expensive for a motor vehicle, and oil is so energy rich you get plenty of performance without bothering.
