[Episode #188] – Getting to a 100% Clean Grid

Dec 21 2022

How much of a role might wind, solar, nuclear, transmission, power plants equipped with carbon capture and sequestration (CCS) technology, or direct air capture of CO2 play on a 100% clean power grid? Which mix of those technologies would provide the cheapest pathways to a clean grid?

And once we have met 90% of the need for grid power with clean generation, what will we need to meet the last 10% of the demand for grid power? Will it be ‘overbuilt’ wind and solar? Dispatchable geothermal, hydropower, and bioenergy generators? Seasonal storage using hydrogen or batteries? Conventional fossil-fueled plants with CO2 capture? Or might it be some mix of flexible demand technologies? Or some or all of the above?

For that matter, how certain can we even be about modeling the possible solutions years or even decades ahead? Are there solutions that might play a large role in the future but that we can’t yet model very well? How confident should we be that whatever the solutions turn out to be, we will end up with not only a grid that is completely free of carbon emissions but also one that is fully reliable?

In this episode, we speak with a senior researcher at the US National Renewable Energy Laboratory (NREL) who has been researching and modeling grid power for many years. In this quite technical discussion, we review two new NREL reports that address these questions and show that producing a 100% clean power grid is not only technically feasible by a variety of pathways but also commercially feasible and ultimately, cheaper than continuing to run the fossil-fueled power grid we have today.

[Episode #131] – Decarbonizing the US by 2050

Sep 30 2020

Mini Episode

Is it possible to decarbonize the economy of the United States, and get to net-zero emissions by 2050? A team of researchers from 15 countries who are part of the Deep Decarbonization Pathways Project think so, based on their deep modeling of the US economy as part of the UN Sustainable Development Solutions Network (SDSN). We introduced this work at a high level in Episode #129, during our conversation with Dr. Jeffrey Sachs, the Director of the SDSN. In this episode, we take a deep dive into the modeling itself with one of the modelers involved in the project. We’ll look at the specific energy technologies, devices, and grid management strategies that will make decarbonization by 2050 possible, and see why they think that decarbonizing the US is not only achievable by 2050, but practical, and very, very affordable.

[Episode #125] – Beyond Planet of the Humans

Jul 8 2020

Mini Episode

Planet of the Humans, by filmmakers Michael Moore, Jeff Gibbs, and Ozzie Zehner, has been roundly criticized by everyone involved in energy transition, and rightly so, because it’s more than a decade out of date. But it did manage to confuse some people about the true state of energy transition, and misled them into believing that wind and solar are some kind of hoax perpetrated on an unsuspecting public by evil billionaires. Even worse, some opponents of energy transition started using the film for their own purposes.

But we think everyone—including the filmmakers themselves—rather missed the point of what the film was really about, which isn’t energy transition at all. It’s something else entirely.

In this episode, we speak with Dutch energy analyst Auke Hoekstra about how the film isn't actually about renewable energy at all by focusing on the entire worldview of the filmmakers. You may have read some critiques of the film already, but we guarantee you haven’t heard this take on it!

[Episode #31] – Transition in Ireland

Nov 30 2016

Full Episode

Ireland is one of the most advanced countries in energy transition, getting over a quarter of its electricity from renewables. It also has one of the most ambitious targets—to obtain 40% of its electricity generation from renewables by 2020—and the resources to be more than 100% powered by renewables, given time and technological development. On the flip side, it also has a severe dependence on imported fossil fuels, and relies on some of the dirtiest power plants in the world.

In this episode, we explore this curious mix of reality, ambition, and potential with the leader of Ireland’s Green Party, a bona fide energy wonk and a longtime supporter of energy transition. From Ireland’s domestic renewable resources to the tantalizing possibility of the North Seas Offshore Grid initiative, it’s all here.
