When do we get the next one?
Your last point is the most important one in my opinion. OP implied we have to chose between nuclear and solar/wind but it’s plain false.
I thought about it when typing it, but I carried the habit from reddit over to lemmy to consider someone beginning a chain of comments as OP.
It’s definitely not the original meaning, but I saw it fairly common to use OP to refer to the author of an initial comment when responding to one of its child comment.
