Carbon neutrality is going to be so standardized that you will look at anything that is not carbon neutral and go, "where the hell did that monster come from?" It's exciting.

We're going to get to the point where we ask how the hell we put up with high carbon for so many years. You thank your lucky stars, because you are seeing this transformation in your lifetime. You are going to tell your children and your grandchildren you saw this whole thing in front of your eyes.

We cannot ask others to do what we have not done ourselves.

We are just about to cross the 400 parts per million threshold.

The U.S. military is investing in new storage technology because most of the weight that soldiers carry on their backs is batteries. Once that gets developed for the military, it will be expanded to civilians.

The fact is, when you talk to people, they know that something weird is going on, particularly people who are connected to the land or the water. They can see it. What perhaps is not so evident to them, unfortunately, is what the solution is. But whether they call it climate change or not, it doesn't matter. The point is, they can see there's something fundamentally weird going on here.

We will move to a low-carbon world because nature will force us, or because policy will guide us. If we wait until nature forces us, the cost will be astronomical.
