I believe it is mostly from people installing solar panels. It's pretty easy to fall off a roof if you're not careful

And given the comparatively modest energy output per unit, it wouldn't take many rooftop falls to put a substantial dent into the deaths per trillion kilowatt hours number.

Put it another way, if California produced 0.0004 trillion kilowatt hours of solar power every year, that would put the death rate of solar installers at one every five to six years. Sounds plausible.

Why is this downvoted? I have the same question.

I’ve been told not to discuss downvoting (see faq). That said i think too there should be a proposal to comment what you don’t like on downvoting as it is in stackoverflow... otherwise people neber know how to change their behavior.

I like to think the up button is small, and it was an accidental downvote, its happened to me a few times.

I don't know, there's the "unvote"/"undown" buttons to correct these kinds of mistakes, but I guess most people won't double-check.
