> The problem for cryptocurrency is there’s no free lunch

There absolutely is a free lunch.

In renewable energy, there is a massive amount of "free" energy that is not being used for anything, and is literally being thrown away, because it can't be stored or used during the time of day that it is generate.

That energy is free. There is zero downsize to spending it on guessing number. It might even be negative value energy, actually.

Did you know that sometimes energy prices go into the negative, and people will pay you to use it? Something to do with the electric grid, and difficulty of destroying energy, I am not sure.
