The laws of supply and demand drive up the price, inevitably, over time. But solar and wind are abundant and renewable resources.

Donald Trump never misses an opportunity to miss an opportunity. Here's an issue where his concern is this line with public opinion, but the way he deals with it is actually puts him in a super minority in terms of people who are able to somehow bring himself to support his language and demeanor.

We're just trying to end illegitimate government support for a single technology, which is un-American. We should be leading the world in the next generation of technological innovation. But we can't unleash private capital because of what the government is doing to stifle innovation and to choke competition.

I'm an environmentalist, and I don't want you to have a disposable aluminum can. I sure as hell don't want to have a disposable worker and I don't care who you vote for.

Deep patriots don't just sing the song, 'America the Beautiful' and then go home. We actually stick around to defend America’s beauty -- from the oil spillers, the clear-cutters and the mountaintop removers.

If the CWS trainings were mandatory for all white activists, the progressive movement in the United States would be unstoppable.
