I'm interested in that thing that happens where there's a breaking point for some people and not for others. You go through such hardship, things that are almost impossibly difficult, and there's no sign that it's going to get any better, and that's the point when people quit. But some don't.

If we want energy security, then we have to reduce our appetite for fossil fuels. There's no other way. Other issues may crowd the headlines, but this is our fundamental challenge.
