I didn't see a distinction between renewable and generated electricity, just overall consumption to produce the coins.
I do remember when bitcoin was being mined by people with out of the box home computers, some formulas that calculated the energy consumption and compared it to the benefit of mining a coin. I don't remember the bitcoin cost at the time but unless your computer was being utilized for other work and mining in the background you were losing money.
Anyway still seems crazy, appreciate your thoughts
