The record-breaking extreme weather events causing chaos across the globe should be a wake-up call. The transition to a low-carbon economy will be much more painful if we wait until there is a climate crisis before recognising that more than half of the world's fossil fuel reserves will have to remain in the ground.

The fact that solar has gone down 80 percent since 2008 is astonishing. Wind is perhaps not coming down as quickly. Lack of storage - batteries - is a bottleneck. That makes it very difficult to put large amounts of renewable energy on the grid.

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.

No architect should design buildings that import a huge amount of energy.

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.

We shouldn't have stupid cars that use liquid fossil fuels. Come on, how outmoded is that? We have to get to the point where this is no longer a part of our experience.
