Higher energy costs are unavoidable in all future scenarios.

The Trump phenomenon has a lot of really good stuff in it, the anti-elitism, the concern for America's economy in the Rust Belt, the desire to see better days for the country. That's all great stuff. Some of that stuff is Bernie Sanders stuff. The problem is that it's marbled through with xenophobia and misogyny and bigotry.

Donald Trump's a hell of a performer, he's a hell of an entertainer. If you put him on and let him say his crazy stuff, you're going to get a lot of viewers. If you take him off and have some sober discussion about what's going on in Syria, you're going to lose 80 percent of your audience.

Religion has gotten a bad rap for good reasons. Often, there are a lot of people - women, LBGT, and others - you know, hierarchical monotheism has been a real source of a type of oppression.

Environmentalists and clean energy champions should stop telling people that we are working for "sustainability," which nobody understands.

We're now moving into a stage where the green economy isn't just going to be the place for people to spend money. It's going to become a place where a lot more people can earn money, and also save more money. These kind of solutions require collective action and government action. So as an advocate for government change, even somebody like me gets to have a role.

A one-sided analysis of anything always leads you into the wrong direction.
