For 41 of the past 49 days, the fifth largest economy in the world has met >100% of electricity demand using solar, wind and hydro generation, frequently exceeding 140% of demand. What lessons can be learned? What does this tell us about future of energy? I asked Prof. Mark Jacobson, the most respected renewables voice on the planet …

What will the global energy mix look like in 2060? Which technologies will dominate in future, and which will dead-end? What about the toughest problems, like powering long range ships and aircraft? What happens to nuclear? I asked Michael Barnard, consultant to the biggest energy investors on the planet ...

Insurance companies must deal with the financial realities of climate change. They must make quantitative decisions and translate risks into dollars. They must do it for today’s impacts and predicted future impacts. And behind the insurance companies are the reinsurance companies who act as shock absorbers to the industry on a global scale …

TRENT THOMSON: The frequency of those perils – wildfire, floods, storms – have gone up by about 450% over 30 years, for very large losses. And the severity of those events have gone up by 1,500%. And so, what's driving that? It's economic growth, it's the value of the assets. It's the urbanization, people wanting to live more in cities, around the world, and that concentration of risk ...

If we allocated EIGHT TIMES all the renewable energy in the world to Direct Air Carbon capture (DAC), we still WOULDN’T REDUCE CO2 BY A SINGLE MOLECULE; we would ONLY just be keeping up with new emissions …

I love hydrogen. It burns clean. It can power long-distance trucks and ferries. It offers long-haul aviation a pathway towards a (nearly) net-zero future, and it gives us a way to make our steel without burning all that coking coal. But lovely hydrogen can only ever be a SMALL part of our future. Here’s why …

Has Martin Green done more than any other human to safeguard our future? For 50 years he has pushed the cost/efficiency boundaries of solar cells, setting world record after world record, and his technology is now imbedded in 91 percent of worldwide solar module production. Who better to sit down with to explore the myriad ways we will extend the solar contribution to our future ...

BRUCE MCCABE: So it's just at the commercial level we're sitting at 20% ? MARTIN GREEN: That’s right, yes. We hold the record for overall conversion of sunlight at 41%. It's proving difficult to translate that into a low-cost device, but I think eventually we'll be successful. So we have the potential for essentially doubling the efficiency …

Can lawyers save the planet? I asked the world’s foremost climate lawyer, Michael Gerrard, Professor at the Columbia Law School and Founder of the Sabin Center for Climate Change Law. What a privilege it was to spend time with this lifelong advocate for sustainability! We discussed the current status of climate litigation, what’s next, and the role it can play in changing the behaviours of greenhouse gas emitters and securing the future of our planet.

Bruce McCabe: We're here to talk about climate change law and where we're going … it seems that litigation and legal pathways can potentially play as much or an even more important role in changing our behaviours, and that's what I really wanted to explore with you today by starting with a premise … “Can lawyers save the planet?”

I asked someone who was flying one. The person who made me think differently about electric aviation was an engineer by the name of Joshua Portlock. I had big lingering doubts about the battery/weight compromises, but here was this guy making noise about the subject, trying to get approvals to set up a commercial sightseeing service …
