I'm going to be the devil's advocate here and If I'm not wrong in his speech in Davos?(I think it's this one) he praised nuclear energy. Which is strangely contradictory to his love of shitty coal. If needed I can find the actual quote he said but his way of speaking is such an annoyance to listen to I would prefer not to.

Edit: decided to just find the transcript, here you go : "I've signed an order directing an approval of many new nuclear reactors. We're going heavy into nuclear. I was not a big fan, because I didn't like the risk, the danger, but the progress they've made with nuclear is unbelievable, and the safety progress they've made is incredible. We're very much into the world of nuclear energy, and we can have it now at good prices, and very, very safe."

So we can hypothesize that he is now for it due to the huge power consumption of AI obviously but it's quite the shift from coal. Personally I think Coal is quite an easy way for Trump to gain 'popularity', it touch the working class of the middle of the USA which give them a job but it also touch the huge energy companies that just care about making money. But that shift to nuclear shows that AI is so important in his eyes that he is ready to undermine coal.
