We can't be anti-everything - we need an energy plan that adds up. But there's a lack of numeracy in the public discussion of energy. Where people do use numbers, they select them to sound big and score points in arguments, rather than to aid thoughtful discussion.

The United States consumes power per land-area at a rate three times the average. Even though they are more energy efficient, densely populated industrial countries like Germany, Britain and Japan have even bigger power consumption per area.

All renewables, much as I love them, are diffuse. They all have a small power per unit area, and we have to live with that fact.

I was distressed by the poor quality of the debate surrounding energy. I was also noticing so much green wash from politicians and big business. I was tired of the debate - the extremism, the nimbyism, the hair shirt. We need a constructive conversation about energy, not a Punch and Judy show. I just wanted to try to reboot the whole debate.

You either keep the forest standing, which takes jobs away from indigenous people who need to feed themselves, or you cut down the trees, which affects the climate. In the long term, you have to protect the forest.

One thing is that you won't get climate action without equity, and Greens around the world have always understood this. This has been the dividing point between the green party of France and Emmanuel Macron: You can't get climate policy without equity.

There's something outrageously funny about the bold-faced lying that's going on, in a general way. Just the blatant denial of facts, whether it's climate change or crowd sizes. Every day, there's another blatant lie. I think there's comedy in there somewhere.

The shift to a cleaner energy economy wont happen overnight, and it will require tough choices along the way. But the debate is settled. Climate change is a fact.
