Is there any point in fact-checking Trump's tirades against renewable energy?

It's too depressing to go into all of the various lies about renewable energy and climate change that Donald Trump reeled off at his address to the UN General Assembly yesterday. Among other howlers, he reiterated his unfounded beliefs that renewable energy sources like wind and solar "don't work" and are "too expensive", called the Paris Agreement a "scam" and all of consensus climate science a "hoax", claimed China and Germany are pulling back from renewable energy, called the UN'S assessment of climate change impacts are "exaggerated" and "incorrect" and a "con job", that reducing carbon emissions costs jobs. His solution to all this? More "clean, beautiful coal".

Wow. It's hard to know where to start, but ABC has already fact-checked most of these ridiculous claims and outright lies, so I don't have to. As Trump strengthens his economic stranglehold over the rest of the world, he is more and more forthright in putting forward his own magical and unsubstantiated beliefs about global warming and clearly energy. 

What's still not clear to me is why. Is he really in the pocket of the American coal lobby? I find that hard to believe. Are his views all coloured by the wind turbines just offshore from his Scottish golf course? I can just about believe he is petty enough for that, but hard to think that his whole worldview has been changed by that. Is it just a "conservative" desire to return to the American dominance and global influence of the 1930s (1950s? 1890s?)? Again, it doesn't make much sense logically, but logic is nothing to do with it. People have been trying to psychoanalyze Trump for years, and remain perplexed. 

I guess all we can do is keep fact-checking Trump's nonsensical tirades. We're not going to change his mind; he only listens to himself. But there is a small chance - and I admit it's a small one - that his followers may be swayed by the truth. 

If we admit the truth to ourselves, though, perhaps a more likely outcome is that, if Trump keeps banging on about this stuff, he will persuade more and more people by sheer force of will.
