I'm not sure about other countries, but in the United States many utilities are not scrambling to build new generation. They are looking to replace old plants as they age and becoming more expensive to maintain. There are 60+ year old coal plants that are being shut down and converted/replaced with natural gas plants. This process takes time. The load growth profile is much slower than it used to be, so you can't just build new plants without taking something offline. This is the same argument to be made for electric cars replacing ICE vehicles. You can't ignore the underlying replacement cycle.

Tesla?

I would love to hear his post-mortem on GM. As I understand it, most of his GM position was in the B Warrants, so perhaps with theta decay working against him he decided now was a good time to sell. Or perhaps he sold purely because he viewed his investment as a "mistake". I don't see how both GM was a mistake and Fiat was a success.
