We have climate change caused by greenhouse gas emissions, mostly from human power and transportation infrastructure. At the same time, we have 2 billion people who live in energy poverty.

If your incentives are set up wrong - if for some reason you reward people for behavior that's actually bad for your customers or your organization - then you're going to encourage that behavior.

Often an idea has impact far larger than the person who originated it.

On almost every environmental issue I care about, in fact, I've been wrong at one point or another. I used to think that climate change was no big deal, that most environmental problems were massive exaggerations, that oil reserves were effectively unlimited, and more.

You have to be able to generate usable energy without greenhouse gas emissions and you have to be able to do it cheaply if you want people to choose that approach.

When you're managing a large number of people, you learn that incentives matter tremendously. You really want people to be rewarded for doing the right thing for the customers and the organization.

The more widely you can spread this notion of achieving ROI by preserving and improving ecosystems, the better.
