Disclaimer: Im no Electrical Engineer just an electricity consumer ( and producer from my solar array) But That sounds BS. Correct me if this arithmetic is incorrect..
Someone says that 10,000 EVs say (Average storage capacity c. 75kwh) so Threequarters of 1 (one) Megawatt (.75MW)
will outpower 5000 turbines with 3-5 MW capacity or 15-25 Megawatts.
even if the average BEV had a capacity of 150kwh and thereby double the sum above
