The movers and shakers on our planet, aren't the billionaires and generals, they are the incredible numbers of people around the world filled with love for neighbor and for the earth who are resisting, remaking, restoring, renewing and revitalising.

In certain ways, I think the work in the Evangelical community has been the most interesting and the most promising. Partly because Evangelical congregations may be harder to convince about issues but, on the other hand, are more likely to do something about it.

I think the best way is to keep stressing, that, as we build out a new energy system, one of the best things about it, if we do it right, will be that it will be more local, more democratic, more distributed, and, in the long run, much more economically sensible.

That's why people are standing up again to fight the Keystone pipeline in Nebraska and South Dakota and Montana. Everyone is well aware of what this industry is about. It engages not only in those kind of practices, polluting people's water, but it has polluted our political life now for a quarter century.

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.

Stop thinking about global warming as a future threat and understand it instead as a present emergency, one that requires a far stronger policy response than we'd imagined.

I try not to be either optimistic or pessimistic. I try not to think about outcomes on that scale. My job, it seems to me, is to wake up every morning and figure out how to cause as much trouble for the fossil fuel industry as I can.
