1) Even accounting for the differences between EV's and ICE cars and trucks there will be a huge amount of electricity needed in the future to power these EV's

The whole electric power consumed per year is around 38 Trillion Btu. The amount of BTU's consumed in transportation

2) is 29 Trillion Btu.

This is just rough math so don't hold me to it but ICE cars are around 30% efficient so that is around 18 Trillion Btu's

But then you have to add back 30% for Power generation losses and EV's losses.

So around 23 Trillion BTU power generation will

3) have to be added to the grid if we want to power all our cars and trucks by electricity.

I have no idea what the future holds be I do know we will have to add at least 50% of new power generation either through a combo of solar, wind, and natural gas.

4) It is just pure physics folks. I know my math is off since this is just back of the envelope math but at the end of day if we want to switch to EV's we are going to have to add a heck of a lot of power generation to the grid some how some way.
