39% renewable, which is actually higher than I expected. I said renewable and opportunistic power capture. The latter is a large proportion of mining because it is effectively free income. There are a lot of places in the world where excess power is generated and wasted because there aren’t uses on site. Bitcoin mining is a relatively cheap way to offset cost of operations in these areas.

Where does the 80-90% number come from, though? Is that just you speculating or has someone come up with that estimate?
