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.

When you have a vision of where you need to go, it sounds utopian. But when you get to the tipping point, your understanding switches.

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.

We have already used more than half of that budget. This means that three quarters of the fossil fuel reserves need to stay in the ground, and the fossil fuels we do use must be utilized sparingly and responsibly.

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.

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

This is probably the most difficult task we have ever given ourselves, which is to intentionally transform the economic development model, for the first time in human history.
