If you have found yourself occasionally challenged to follow some of the more technical conversations we have here, or even if you just want to brush up on the fundamentals, this mini-series is for you!

In this lagniappe episode, we ask: what are some unanswered questions about the energy transition from five years ago, but that seem answered today? And what are the new questions that have emerged over the past five years which remain unanswered today?

Low-carbon electricity output from wind, solar, nuclear, hydro and biomass rose by just 1 terawatt hour (TWh, less than 1%) in 2019. It represents the smallest annual increase in a decade, where annual growth averaged 9TWh. This growth will need to double in the 2020s to meet UK climate targets while replacing old nuclear plants as they retire.

In other words, we have a long way to go if we choose to reduce emissions by simply replacing fossil fuels with wind turbines. As the ecologist Bill Rees noted in his recent Tyee analysis, “the green energy transition is not really happening.”

Champions of energy transition see it happening relatively quickly, emphasizing the advances that are being made in technologies, policy, and projects. While fossil fuel incumbents see a long, gradual process of energy transition, assuring us that demand for their products will remain strong for decades to come. So who’s right? Is energy transition going to be rapid, or gradual?

California is the fifth-largest economy in the world and likes to shout about its genius at innovation, but it is a victim of its lack of energy innovation. It’s a climate disaster zone, with the new reality of hotter, dryer conditions made far worse by the outdated power grid and corrupt private corporation in charge of distributing gas and electricity.

That begs the question: why aren’t developed nations, such as European nations, rapidly replacing their fossil fuel uses with renewable energy and why do they still have high per capita CO2 emission rates, typically much higher than developing nations?

The better that one understands a problem, the greater the chance of solving it. So it is with climate change, a crisis demanding far-reaching social transformation. But just how far-reaching? A broad curriculum that develops activists’ clarity and unity of vision could be an essential pillar to advance the climate movement’s preparation, ambition, and cohesiveness.

For our 100th episode, we thought we’d do a little something special: Interview professors from four US universities who are using the Energy Transition Show as coursework, and make the full show available to everyone, including non-subscribers.

As more distributed energy resources arrive unbidden onto the power grid, they are increasingly requiring us not to just think about new utility business models, but to radically rethink what a utility might look like.

The upshot is that government policy is offering large incentives to new nuclear, gas-fired power and also shale gas extraction – but, paradoxically, not many are actually being developed. Meanwhile the cheapest options – onshore wind, solar and offshore wind – are being discriminated against.

Are investments in energy transition, especially for public dollars in the form of incentives or subsidies, worth it? Do investments in energy efficiency truly pay off, or does efficiency just make energy cheaper because we’re using less of it, encouraging customers to use more of it—a phenomenon known as the rebound effect, the backfire hypothesis, and the Jevons Paradox?
