The cost reductions for renewable energy continue downward in a very dramatic way. We're in the early stages of a sustainability revolution in the globe that has the scale of the industrial revolution but the speed of the digital revolution.

There are a lot of changes underway right now. I'm excited by the prospect, and I look forward to working in the months and years to come to accelerate this transition.

And if you are a believer, as I am, I think God intends for us to open our eyes and take responsibility for the moral consequences of our actions.
