[Episode #248] – The Future of Geothermal

Although geothermal power plants have operated commercially in various parts of the world for decades, the sector hasn't attracted the investment needed to reduce costs and enable global deployment. But with further development, new methods of harnessing geothermal energy to produce heat and electricity could deliver as much as 800 GW of geothermal power capacity worldwide by 2050. That’s equivalent to the electricity demand of the United States and India combined.

In December 2024, the International Energy Agency (IEA) published "The Future of Geothermal Energy," a report exploring opportunities in this sector.

Our guest today is a lead author of that report. In this conversation, Heymi Bahar, Senior Renewable Energy Analyst with the IEA, discusses geothermal energy’s full technological potential and strategies for unlocking investment in this promising resource.

[Episode #243] – Decarbonizing Heating

Heat pumps work almost like magic—delivering several times more heat energy than the electricity they require to run. Modern heat pumps are so efficient, they can even extract warmth from freezing temperatures, keeping buildings comfortable despite the cold outdoors.

With many policymakers seriously exploring ways they can accelerate heat pump adoption, we thought now is the perfect time to offer some specific and useful guidance on designing effective approaches for realizing this goal. Our guest today is Dr. Richard Lowes, a specialist in heating technology and policy with the Regulatory Assistance Project in Europe. He also co-chairs the Clean Heat Forum international policy network. Richard has advocated for heating policy since earning his doctorate in the subject from the University of Exeter a decade ago, advising the Scottish government’s heat decarbonization programme board, various UK parliamentary select committees, and serving in multiple roles within the UK government.

In this episode, we discuss why the energy transition requires us to fix leaky buildings, tradeoffs between energy efficiency upgrades and simply swapping out old boilers for heat pumps, the best policies to encourage heat pump adoption, and the measures available in Europe to support all these efforts.

Guest:

Dr. Richard Lowes is a specialist in the technology and policy associated with heating and is based within RAP’s Europe programme. He joined RAP in 2021 with over 10 years’ heat policy experience in industry, academia and working with policymakers. Richard currently coordinates much of RAP’s work on clean heating in Europe and globally, and as part of this, co-chairs the Clean Heat Forum international policy network.

After earning an advanced degree in energy policy, Lowes worked for UK energy company SSE before moving on to gas transporter SGN, where he led the company’s work on policy and public affairs. This was at a time when few were considering, let alone working on the issue of cleaning up heating. In 2014 he moved to the University of Exeter, where he completed a doctorate alongside various heat policy and regulation-focused research projects. He was particularly known for his analysis on lobbying and the political influence of the gas industry. He also lectured on energy policy. Since 2019, he has been a non-executive director of the Scottish government’s heat decarbonisation programme board.

Richard Lowes has a track record of delivering high-impact heat decarbonisation research and remains a research fellow at the University of Exeter. He has provided oral evidence to multiple UK parliamentary select committees, was an expert advisor to the National Audit Office inquiry into Great Britain’s Renewable Heat Incentive, and was an advocate for sustainable heating at the 2020 Climate Assembly UK. He had the privilege of being appointed as a specialist advisor for the UK house of commons inquiry into economy wide electrification in 2023.

He holds a first class honours degree in geography and environmental management, in addition to his master’s (with distinction) in energy policy and doctorate in the development of UK sustainable heating policy. He was appointed as a fellow of the energy institute for his expertise in energy policy in 2023.

[Episode #225] – Demand Side Solutions

Energy transition is often depicted as a choice between different supply-side technologies such as wind or solar versus oil and coal. However, the demand side of the energy transition — focusing on efficiency improvements to buildings, adopting walking and biking over driving, and electrifying consumer appliances — deserves just as much attention.

Would you believe that widespread adoption of demand-side measures like these could cut the UK’s energy demand in half without sacrificing services or quality of life? That’s one of the key insights our guest in this episode has to share.

Nick Eyre is one of the most well-informed experts on the demand side of the energy transition. He is Professor of Energy and Climate Policy, and Senior Research Fellow in Energy, at the Environmental Change Institute at Oxford University in England. He serves as the Director of the Centre for Research into Energy Demand Solutions, which is UK Research and Innovation’s (UKRI's) primary investment in energy use research. He is also a Co-Director of the Oxford Martin Programme on Integrating Renewable Energy, which is undertaking research on the combined, technical, economic, social and policy issues in moving to electricity systems with very high levels of variable renewables.

For the past five years, Nick has led a comprehensive project involving hundreds of researchers to review nearly 500 publications on the demand side of energy. This project concluded at the end of 2023, and he joins us today to share its key insights. He’ll help us understand the most important demand-side decarbonization strategies in 2024, and what we can do to accelerate their deployment. It’s a really comprehensive, yet very accessible (and not too geeky) discussion that offers at least a few practical insights that all of our listeners could readily consider applying in their own lives.

Guest:

Nick Eyre is Professor of Energy and Climate Policy, and Senior Research Fellow in Energy, at the Environmental Change Institute. He is Director of the Centre for Research into Energy Demand Solutions, which is UKRI’s main investment into research on energy use. He is also a Co-Director of the Oxford Martin Programme on Integrating Renewable Energy, which is undertaking research on the combined, technical, economic, social and policy issues in moving to electricity systems with very high levels of variable renewables.

Professor Eyre acts as scientific advisor on climate change to Oxford City Council. He is interested in the role of public policy in reducing energy demand and carbon emissions, and the transition to zero carbon energy systems. This includes the integration of renewable energy into energy systems, energy market reform, policy instruments for energy efficiency and the role of local government and communities.

Professor Eyre was one of the UK’s first researchers on mitigation of carbon emissions, and was co-author of a presentation to the Cabinet on this issue in 1989. In 1997, he wrote the first published study on how the Government’s 20% carbon emission reduction target might be delivered. He has advised successive governments and a wide range of Parliamentary inquiries. He managed a large European Commission programme on the external costs of energy and was lead author of the report used as the basis for the UK Government’s first estimate of the social cost of carbon. From 1999 to 2007 he was Head of Policy and then Directory of Strategy at the Energy Saving Trust.

[Episode #218] – Accelerating Decarbonization in the US

How can we accelerate the decarbonization of the entire US economy?

In this episode, we discuss the energy-related decarbonization strategies outlined in a new report from the National Academies, titled “Accelerating Decarbonization in the United States: Technology, Policy, and Societal Dimensions,” with Dr. Sue Tierney, a Senior Advisor at Analysis Group and a renowned expert in energy and environmental economics, regulation, and policy. Dr. Tierney played a key role in the Committee on Accelerating Decarbonization in the United States, which developed and coordinated this landmark study. We explore how decarbonizing the US requires much more than simply substituting renewables for fossil fuels in power generation and EVs for oil-burning cars. A broad array of solutions must be deployed, but they face numerous barriers and risks to implementation.

Trillions of dollars have been allocated for these energy and technology solutions through three significant laws passed in 2022: the Infrastructure Investment and Jobs Act (IIJA), the Inflation Reduction Act (IRA), and the Creating Helpful Incentives to Produce Semiconductors (CHIPS) Act. However, effectively mobilizing these funds requires willing collaboration from a diverse group of local, municipal, and state actors, including elected officials, regulators, agency staffers, as well as community and business leaders.

Listen in to learn why delivering a successful energy transition, along with a host of other benefits such as justice, equity, health, jobs, and sustainability writ large, necessitates understanding the barriers to implementation and identifying the types of policies and programs needed to keep the US on track to achieving net zero.

Guest:

Dr. Sue Tierney is a Senior Advisor at Analysis Group and is an expert on energy and environmental economics, regulation, and policy, particularly in the electric and gas industries.  Previously, she was the Assistant Secretary for Policy at the U.S. Department of Energy, and in Massachusetts, she was the Secretary of Environmental Affairs, Commissioner at the Department of Public Utilities, and head of the state’s Energy Facilities Siting Council. She currently chairs the Board of Resources for the Future and the National Academies’ Board on Energy and Environmental Systems, and serves on the boards of other NGOs and foundations.  She was a member of the National Academies’ Committee on Accelerating Decarbonization in the U.S. and the Committee on the Future of Electric Power. Her Ph.D. is in regional planning from Cornell University

[Episode #217] – Passivhaus in Scotland

Discussions about energy transition often overlook the crucial role of reducing the energy consumed to maintain comfortable temperatures in the spaces where we live and work. Remarkably, generating heat, the largest end-use of energy, accounts for 40% of global fossil CO2 emissions, with the majority of this heat used in buildings. About half of the energy used in buildings is for their heating and cooling, and because fossil fuels still meet the bulk of heating energy demand, this contributes to about one-fourth of global energy-related carbon emissions annually.

Addressing this challenge by improving building efficiency and reducing thermal losses is arguably the most critical step we can take to facilitate the energy transition. However, strong policies or targeted programs to this end are largely absent worldwide.

A transformative solution is the adoption of the Passivhaus standard for new and existing buildings. Retrofits to meet this standard could drastically reduce energy requirements for buildings, accelerating our progress toward the energy transition.

In this episode, we are joined by Es Tresidder, a Passivhaus consultant who works with an architecture firm to advance the use of the Passivhaus standard and techniques. He walks us through the Passivhaus standard and how to meet it. He also shares the story of the ‘deep retrofit’ performed on his own house in the rainiest and coldest part of Scotland, transforming it into a home that is far healthier and more comfortable, all while significantly reducing its energy consumption.

Guest:

Dr. Es Tresidder is a Passivhaus designer based in Fort William. He works as a Passivhaus and energy specialist for John Gilbert Architects, one of the leading environmental architecture practices in the UK. His work at John Gilbert Architects currently focusses on their larger and more complex projects – Passivhaus schools, leisure centres and retrofits. Es has a PhD in low energy building design optimization, using genetic algorithms to optimize building designs for efficiency and cost. In 2023 he finished a retrofit, to Passivhaus EnerPHit standard, of his own home in Fort William, Scotland. Once certified he believes this will be the first EnerPHit of a modern timber-frame house in the UK, and potentially the world.

[Episode #197] – Virtual Power Plants (VPPs)

Full Episode

The time may have arrived for Virtual Power Plants (VPPs) to fully realize their potential. In a VPP, groups of distributed energy resources (DERs) like EVs, batteries, and heat pumps can be managed to consume power when it is inexpensive, avoid consuming power when it is expensive, and even provide power back to the grid when supplies are limited.

While VPPs have been around for many years, operating commercially in places like Australia, the US power grid has not seen wide-scale integration. This is now changing because VPPs can help the grid do more with less - supporting new loads without requiring expensive new investments in grid expansion.

In this episode, Jigar Shah, Director of the Loan Programs Office at the US Department of Energy, joins us to share his vision of a much-expanded role for VPPs on the power grid and why he thinks the sector is ready to scale up. You’ll hear how a handful of VPPs and programs to support them have been launched in the US. You’ll also hear how the US Department of Energy is exploring ways to accelerate the development and integration of VPPs, including making financing available through Jigar’s office to support the adoption of VPP-enabled DERs under the Title 17 Clean Energy Financing program.

And because Jigar is with the Department of Energy, sharing information that should be accessible to everyone, we decided to make this one of our occasional lagniappe shows and put it in front of the paywall so that premium and free listeners alike can enjoy it. Hey free listeners, now you can see what you’ve been missing!

[Episode #187] – Transition in Vermont, Part 2

This is Part 2 of the first series in a new format we are piloting for the Energy Transition Show. Instead of exploring a particular topic with one guest who has a non-commercial perspective, as most of our shows so far have done, this new format aims to tell the stories about how the energy transition is proceeding in some of the places Chris visits in his travels. Through interviews with multiple local experts, including those who are working in the energy sector, we hope this new format will help to demonstrate how the unique challenges and opportunities in every place will determine its particular path through the energy transition.

We are kicking off this new show format with some stories about Vermont for a simple reason: When it comes to the energy transition, Vermont stands out as a place that punches way above its weight. It has innovated numerous policies and mechanisms to reduce its energy consumption and carbon emissions that have been emulated by other US states. And it continues to serve as a model to the rest of the country for effective energy transition strategies.

You’ll learn more about all of these accomplishments, as well as what makes Vermont such an exemplar in the energy transition, in this two-part miniseries based on interviews with eight local experts.

Part 1 was in Episode #186, in which we discussed the supply side of Vermont’s energy picture. In this second part, we look at the demand side.

Interviews with guests featured in this episode were recorded from October 11-15, 2021.
