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.

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.

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.

Often when I'm on TV, they'll ask what are the three most important things for people to do. I know they want me to say that people should change their light bulbs. I say the number one thing is to organize politically; number two, do some political organizing; number three, get together with your neighbors and organize; and then if you have energy left over from all of that, change the light bulb.

We'd like to get the fossil fuel industry on the back foot for a while, having to deal with us.

Where people aren't as deeply reliant on fossil fuel as in the United States, it's far easier for them to imagine change on this scale. When you go to Europe, they're much more ready. They use half the amount of energy per capita that we use. They can imagine using less than that. They see the benefits. They're ready to go.

There are many places where we need to fight important battles to make sure that customers have access to solar.
