Which brings us to our topic this week on Sea Change Radio: energy transitions. Today we are talking about pivots undertaken by some of the worlds largest economies - we are joined by Chris Nelder, an energy expert and the host of The Energy Transition Show podcast. We discuss the problems facing Japan and its growing energy needs 15 years after the Fukushima nuclear disaster, examine Chinas impressive moves away from fossil fuel dependency, and talk about Germanys nimble reinvention of its energy grid after Russias invasion of Ukraine.
