Yeah I was wrong and completely misunderstood the data. I'd edit the post if I could but the timeout for that happened while I was editing. Not sure what confirmation bias I might have: I figured the Fins did their math correctly and was confused about why they were using electric heat.

Anyway, to explain my mistake, the data did not look "insane" to me, it's about right for most countries, and even if it had been correct for Finland the method they described might be favorable (some electric sources need leveling and using extra energy for heat is better than dumping it). Honest mistake, I'm not here with some agenda, and I learned of it by posting.

Anwyay, thanks for the correction! It's amazing (in a good way) that internet communicators can see something that looks plausible, but is wrong, and correct it! You've restored (some of) my faith in the internet.
