We're clearly coming to the end of the fossil fuel era. We have the technology to shift to renewable energy, we have the will of the people. The only thing that's keeping us back is the fossil fuel industry's hold on our political system. That's what we need to change.

No great undertaking ever looks like it's winnable. That only comes later and only if you are lucky and are willing to fight and have a group of folks around you that are willing to do the same thing, too.

Trying to find the story within the story was hard. Filmmaking is such a reductive process in a strange way and you keep whittling away to what is essential.

I am grateful to the fossil fuel industry for bringing us the concentrated carbon that took us through the Industrial Revolution and through the technological revolution and brought us to the gateway of the renewable energy revolution, or what I call the sunlight revolution. But that is where we must part ways. It's the natural order.
