Let's see if I can get this right:
Approximately 289 million cars on the road
Average miles driven per year between 12,000 and 15,000, so let's say 13,500.
289,000,000 X 13,500 = 3.9 trillion miles per year driven.
Estimates are an average ev will use about 30 kwh to travel 100 miles.
So, 3.9 trillion / 100 X 30 = 1.2 trillion kwh of energy per year to power electric cars.
1 windmill can produce up to 43,800 kwh of electricity per year, if it runs at max capacity all day every day.
So, to get the 1.2 trillion kwh of energy per year, you would need:
1,200,000,000,000 / 43,800 = 27,397,260 wind turbines.
An industrial wind turbine needs between 40 and 70 acres of land. We'll go with 50 acres.
So, 27,397,260 turbines X 50 acres = 1.4 billion acres of land
There are 2.4 billion acres of land and water in the u.s.
So, to get the amount of wind energy to power electric vehicles by wind and solar (I think solar is less efficient than wind), you would have to plant wind turbines over half of the u.s.
A coal plant produces about 3.5 billion kwh per year. So 1.2 trillion kwh would require 343 coal plants. In 2019 there were 241 coal plants across the u.s, so we would have to build about 100 more coal plants to make the required energy.
A nuclear power plant will produce about 9 billion kwh per year. There are about 93 nuclear power plants in the u.s of various power output capacities. 9 billion kwh is probably average. So, 1.2 trillion / 9 billion = 133 nuclear power plants. So we would need to build about 40 more of them.
Did I get that right? Either that or I spent all that time to get it completely wrong. Lol
