When you have solar panels, your electricity gets there for free, no one's figured out how to meter the sun yet. And that's good.

You think OWS is radical? You think 350.org was radical for helping organize mass civil disobedience in D.C. in August against the Keystone Pipeline? We're not radical. Radicals work for oil companies. The CEO of Exxon gets up every morning and goes to work changing the chemical composition of the atmosphere. No one has ever done anything as radical as that, not in all of human history.

We have to transition to new technologies, making it more expensive to continue with the old and polluting technologies and cheaper to go to the clean ones.

I think communities of faith are extremely important in this question. I think that all faith communities share a common and unusual distinction in our time of being the only institutions left that can posit some goal other than accumulation for human existence. I think that's enormously important because it is that drive for consumption more than anything else that fuels the environmental devastation around us.

Climate change is the single biggest thing that humans have ever done on this planet. The one thing that needs to be bigger is our movement to stop it.

My guess is that liberating the fossil fuel industry to frack anywhere they want will drive down the rate at which we're converting to sun and wind. And it's entirely a rate problem at this point.

But the truth is that we could win every other fight that we face and if we lose the climate fight, the other victories will be pyrrhic. I don't think even people who are worried about climate change quite understand the scale and speed with which we're now shifting the planet.
