When you pile one lousy assumption on top of another, and then another, you end up with nonsense.
Try this instead:
The US consumes 20 * 10^6 barrels of oil a day
20% of energy is lost to refining
Clean energy to wheels is about 4x the efficiency of the equivalent ICE pathway
>> A full electric conversion therefore requires 4 * 10^6 barrels of oil equivalent
A barrel of oil is about 40*40 kWh
A kW of utility scale clean energy produces about 8 kWh a day
>> A barrel of oil daily is replaced by (40*40)/8 = 200 kW
>>> Total replacement requires 4 * 10^6 * 200 kW
= 800 * 10^6 kW
= 800 * 10^3 MW
= 800 GW
Which completely misses the point that clean energy coming on line even at the snails's pace due to the retarded Trumpers far outpaces EV production.
