> The ridiculous amounts of money they have are their investments.
C'mon, you know what I mean. I bet there are plenty of non-polluting investments that they hold too. They're not suddenly going to become bankrupt because of investing in renewable energy. Maybe they'd be able to afford one less yacht or private jet, but I presume that, like me, you don't really care about that either.
> Hasn't Musk done exactly what you are demanding of him with Tesla and what ever his solar company is?
To some extent, yes. Much as I despise Musk as a person he's done a huge amount for electric cars at least. I haven't heard anything about the solar company recently, and the last I heard it was languishing very far down in the list of Tesla priorities. Tesla home batteries seem to be pretty ubiquitous though.
But we're also talking about personal emissions here, and he hasn't invented an electric jet yet. The point is that we need to radically reduce emissions, and me personally insulating my house doesn't make a blind bit of difference if those at the top of the pile don't make significant changes themselves.
