Best podcast out there

Informative, accessible and optimistic

"Sensible, intelligent and (usually) entertaining people engaged in finding solutions to the climate crisis we have got ourselves into. A must listen for the climate catastrophists (if that’s a thing?)"

"This podcast is hugely insightful in cutting through some of the noise and demystifying the energy transition. It covers a range of topics from policy to technology and also as far as human behaviour…"
