On same-sex marriage.

Trump, 2000:

I think the institution of marriage should be between a man and a woman

2011:

I just don't feel good about it. I don't feel right about it. I'm against it and I take a lot of heat because I come from New York. You know, for New York it's like, how can you be against gay marriage? But I'm opposed to gay marriage.

2015:

I'm just for traditional marriage.

On renewable energy

During a September 2016 speech at the 2016 Shale Insight Conference, Trump said that his “America first” energy approach meant “opening federal lands for oil and gas production, opening offshore areas, and revoking policies that are imposing unnecessary restrictions on innovative new exploration technologies.”

During an August 2016 campaign speech in Fredericksburg, Virginia, Trump said, “According to the Energy Information Administration, the United States has the largest recoverable coal resources in the world. We’re talking clean coal – beautiful, clean coal ... Over 90 percent of U.S. coal is used for electricity. In other words, my plan will make your energy bill much less expensive – much, much cheaper. Hillary Clinton’s anti-energy agenda is a massive tax on the poor.”

In a May 2016 speech to the North Dakota Petroleum Council, Trump said, “The administration fast-tracked wind projects that kill more than 1 million birds a year.”

“In his press conference with reporters before the speech, Trump elaborated: ‘I know a lot about solar,’ he said, ‘the problem with solar is it’s very expensive.’ He made no mention of the fact that solar prices have been dropping precipitously.”

“These are industrial turbines. They make noise. They create shadows. It’s called the flickering effect. And for miles around, the sun comes through and you have shadows, every second a different shadow. A lot of people say they cause sickness because of what happens and probably because of the anguish.”

According to On The Record on Fox News, “Trump: Right now, green energy is way behind the times. You look at the windmills that are destroying shorelines all over the world. Economically, they’re not good. It’s a very, very poor form of energy. Solar, as you know, hasn’t caught on because, I mean, a solar panel takes 32 years -- it’s a 32-year payback. Who wants a 32-year payback? The fact is, the technology is not there yet. Wind farms are hurting the country.”
