A funny thing I like to do with people like this is point out the fact that Elon has perhaps done more than any person in history to get humans off of fossil fuels. And then when they sputter in disagreement I always like to ask who they'd propose instead. If they have any answer at all they inevitably give the name of a person who just demands that someone else do something (e.g. an activist or media figure), never actually someone who has put their time, effort and money into building a better system.
Tesla makes batteries and battery powered cars, which are indifferent of energy source. They do make some solar panels, but are a minor player not even in the top 10 by shipped capacity worldwide. But chineese companies like LONGi Solar and JinkoSolar aren't "one guy" (even though they ship 50x what Tesla does), so I guess they don't count.
Sure, I guess if we ignore the fact that he's spent and continues to spend unfathomable amounts of money on politicians who are very publicly pro fossil fuels and climate change denialists, and does shit like opening data centers powered by the largest gas generators on the planet.
Ok I’ll play, but you’re not going to like the answer: Xi Jinping. Putting aside all the valid criticisms of China under Xi, the scale at which they’ve embraced electric car and solar energy puts anything Tesla has done to shame. We’re talking more solar and wind capacity added in one year than the U.S. has in total. And China has done more to lower the cost of solar panels and batteries than anyone else while dominating global production. None of it would be possible without an intentional national policy.
