Trump holds a grudge against wind turbines, for no other reason than that they "ruined" the view at a golf course / club he owns in Scotland. He tried to get them removed, but lost that case in court.

That's mostly it. Another factor would be Trump getting donations from the oil & gas industry.

When I have drive past the course, I always have the urge to pee. One day I'll get out and take a piss on the green.
