Donald thinks that climate change is a hoax perpetrated by the Chinese. I think it's real.

TRUMP: I did not. I did not. I do not say that.

CLINTON: I think science is real.

TRUMP: I do not say that.

CLINTON: And I think it's important that we grip this and deal with it, both at home and abroad. And here's what we can do. We can deploy a half a billion more solar panels. We can have enough clean energy to power every home. We can build a new modern electric grid. That's a lot of jobs; that's a lot of new economic activity.

So I've tried to be very specific about what we can and should do, and I am determined that we're going to get the economy really moving again, building on the progress we've made over the last eight years, but never going back to what got us in trouble in the first place.

HOLT: Mr. Trump?

TRUMP: She talks about solar panels. We invested in a solar company, our country. That was a disaster. They lost plenty of money on that one.

Now, look, I'm a great believer in all forms of energy, but we're putting a lot of people out of work. Our energy policies are a disaster. Our country is losing so much in terms of energy, in terms of paying off our debt. You can't do what you're looking to do with $20 trillion in debt.
