Despite uncertainty for US clean energy investors, things are looking good for the geothermal sector. US$1.7 billion in public funding was pumped into geothermal projects in Q1 this year - 85% of 2024's entire annual allocation – as breakthrough technologies promise to transform untapped resources into commercially viable clean energy projects.

Enhanced geothermal and advanced geothermal technologies are making geothermal energy accessible anywhere, not just at existing sites chosen for their high-temperatures.

To explore the science behind EGS and AGS, host Sylvia Leyva Martinez is joined by John Plack, VP of engineering at Ameresco. John explains how techniques adapted from the oil and gas sector, like directional drilling and reservoir stimulation, are improving geothermal's commercial viability. John shares what’s changed since the IRA’s passage, the role of EGS, and why improved subsurface mapping is critical to unlocking investment.

Geothermal is currently supplying less than 1% of global energy needs, but could provide 15% of worldwide power by 2050. The US leads global geothermal power production, yet its 4 GW of installed capacity leaves vast resources untapped. Total potential US geothermal capacity exceeds 500 GW, with the best sites in western states featuring temperatures above 150°C and heat flow rates exceeding 80 milliwatts per square metre.

Investment is there, and the technology is there, so has the impact of the Trump administration’s energy policy been lighter for geothermal than other sectors like wind and solar? Why?

In February this year BP announced it was cutting its investment in green energy ventures from $5B to $2B while reallocating $10B to fossil fuels, and abandoning its 2030 oil output reduction target. Shell has also scrapped its planned 20% carbon reduction cut for 2030. It’s not a good display of intent from the perspective of the energy transition. In a highly volatile and uncertain policy environment it’s troubling for investors and clean energy developers. The prioritisation of short-term profit at the expense of long-term climate impact has many implications.

To find out, host Sylvia Leyva Martinez is joined by private investor Ben Dell, Managing Partner at Kimmeridge. He says that while “everyone wants low-cost energy on demand with a minimal carbon footprint, every dollar invested has to be cost-competitive. Philanthropy is not an investing strategy.” What does that mean in the context of clean energy deployment?

Plus, Wood Mac analyst Tom Ellacott joins the show to look at the outlook for oil and gas in light of the news from the majors. As he sees it, gas is a growth fuel for the next 20 - 30 years and the most optimal power delivery system is still renewables paired with small-scale batteries and natural gas. So why are major energy providers flip-flopping with their strategies when this is widely accepted?

The key questions are: how are oil and gas majors adjusting their capital allocation between fossil fuels and renewables? What’s the role of natural gas in the transition? And how should investors navigate volatility and uncertainty in energy markets? You’ll get the answers here.

The Greenhouse Gas Protocol – the global gold standard for measuring corporate emissions – is under review, and the proposed changes could dramatically reshape how clean energy is bought, sold, and reported. New draft rules are expected by the end of the year.

What changes could we see? And how will they impact the energy transition? To find out, Sylvia Leyva Martinez, principal analyst at Wood Mackenzie covering solar markets, speaks with Lee Taylor, CEO of Resurety – a leading provider of data and analytics for clean energy buyers. Lee has spent over a decade helping companies understand not just how to procure renewables, but how to do so with real carbon impact.

Together, they explore what’s changing in Scope 2 emissions accounting, why location and timing of energy use now matter more than ever, and how voluntary clean power markets might evolve. They break down complex concepts like emissionality, 24/7 procurement, and consequential accounting – and what these mean for corporate net-zero strategies, PPA structures, and the future of Renewable Energy Certificates.

If your business buys clean electricity or reports against Scope 2, this is essential listening.

Plus, Taylor shares his advice for buyers and developers navigating the shifting landscape, and explains why the next six months will be key in shaping rules that will define voluntary climate leadership in the coming years.

Nearly 150 days into President Trump’s second term, the outlook for wind energy in the United States - particularly offshore wind - is increasingly bleak. Trump had pledged to end offshore wind development, and now the House Ways and Means Committee is proposing a phase-out of tax credits for renewables by 2031 - a move that would severely impact an already struggling wind sector (over on our sister podcast Energy Gang, we discuss the bill and what it means for renewables – check out that episode once you’re finished here).

Only three offshore wind projects have come online in US waters, with 4 GW currently under construction. In 2024, total wind installations reached a ten-year low at just 5.2 GW. By contrast, Europe has surged ahead, having built 35 GW of offshore wind capacity - ten times the US total – emphasising the stark differences in policy and financing frameworks.

Still, there are glimmers of hope: President Trump recently lifted a stop-work order on a $5 billion offshore wind farm off the coast of New York, following lobbying from Governor Kathy Hochul. The project, led by Norwegian company Equinor, is expected to power 500,000 homes by 2027. However, with developer confidence sinking, experts warn that the stop-start nature of US policy continues to undermine long-term momentum in the sector. 

To forecast the next few years for wind in the US, host Sylvia Leyva Martinez – principal analyst at Wood Mackenzie – is joined by analyst Stephen Maldonado. They explore the policy and technology that’s holding back deployment of offshore wind in the US.

Plus, looking across the Atlantic to Europe, Sylvia talks to WindEurope CEO Giles Dickson, about the financing frameworks for wind in Europe.

Sylvia, Stephen and Giles talk through the lessons for developers and financers: with uncertainty around tax credits and shifting policies, there may be a shift in resources to more advanced projects, putting early-stage ones on hold. Repowering old wind turbines is an option too; Giles explains how. And making use of domestic supply chain strengths is key – compared to solar, wind has more domestic supply chain support.

The US is risking ceding global market share of clean energy to China, permanently.

New tariffs, put in place one day then removed the next. Rising costs for everything along the supply chain. The US clean energy sector is navigating one of its most unpredictable phases yet. From solar to storage, how are developers and policymakers reacting to renewed trade tensions and their impact on the energy transition? 

“This isn’t just about clean energy deployment. It’s about whether the US will have a seat at the table in the future global energy economy,” says Leslie Abrahams, Deputy Director of the Energy Security and Climate Change Program at CSIS – the Center for Strategic & International Studies. She joins host Sylvia Leyva Martinez, a principal analyst covering global energy markets at Wood Mackenzie, to find out what the outlook is for US energy innovation. Escalating tariff policy is shaking investor confidence, altering supply chains, and putting the power firmly with China.

Plus, in the second half of the show, Sylvia gets the developer perspective, from Joao Barreto, who is CEO of EDP Renewables’ distributed generation business in North America. He explains how one of the world’s largest clean energy developers is mitigating risk, adjusting their strategy, and building trust with manufacturers and offtakers amid unprecedented uncertainty.

Sylvia, Leslie and Joao discuss:

• Why US$8 billion in clean energy projects were cancelled in Q1 2025, and what that signals to the market
• How US tariffs on Chinese batteries are backfiring on domestic manufacturing
• The challenge of accelerating R&D while shutting out foreign investment
• How storage and solar developers are hedging their bets
• Whether the US risks ceding global market share to China permanently

They called the film Avengers: Infinity War the most ambitious crossover event in history. We can’t quite make the same claim, but at Wood Mackenzie’s 2025 Solar and Energy Storage Summit, we did record a crossover episode. Sylvia Leyva Martinez, Wood Mackenz’s principal analyst for solar power and host of Interchange Recharged, is joined by Ed Crooks, host of Energy Gang, to discuss the future of energy, and of the electricity grid in particular.

They are joined by Rob Chapman, Senior Vice President of Energy Delivery and Customer Solutions at the non-profit research group EPRI, the Electric Power Research Institute, which aims to help power society toward a reliable, affordable, and resilient energy future. 

Rob talks about a key theme in his work: the importance of flexibility on the electricity grid. Increased reliance on solar and wind power has created challenges in keeping the grid balanced and the lights on. Surging demand for electricity for new data centres to train and run AI models is giving rise to a whole new set of issues. More flexible demand and supply on the grid is increasingly valuable. But where can it come from?

Data centres don’t usually offer a lot of flexibility in their operations. People want to use ChatGPT and watch Netflix even at night and when the wind is low. So what can the hyperscalers do to create flexibility? Are virtual power plants an effective option? And how can the energy industry improve collaboration to find solutions that promote the clean energy transition while keeping prices down?

You can find Energy Gang wherever you get your podcasts, and follow Interchange Recharged with Sylvia Leyva Martinez for deep dives into the innovations that are accelerating the energy transition.

Wood Mackenzie’s 18th Solar and Energy Storage summit is back, in Denver this week. If you can’t make it, don’t worry – we have all the debate and key insight you need to know here on the podcast. Recorded live on day 2 of the summit, host Sylvia Leyva Martinez talks to key industry leaders in solar and storage to answer these questions:

What’s best practice for battery asset management? To answer this Sylvia is joined by Jenny Fink, Director of Asset Management at KeyCapture Energy. They discuss the need to synchronise market operations, analytics and site management. What’s the biggest challenge involved in maintaining safe and efficient battery operations? 

How can developers and investors deal with market volatility? Petter Skantze is VP of Infrastructure Development at Nextera Energy. He talks to Sylvia about challenging load demands; stakes are higher now as project delays are a block to economic growth. Compared to legacy fossil fuels, solar and storage development lead times are many times faster – so why aren’t we seeing accelerated deployment?

Finally, Sylvia talks with Jeff Cramer about the benefits of community solar. Jeff is President and CEO of the Coalition for Community Solar Access, and he explains how community solar has grown from a niche offering to a key benefit to consumers. New York and California are leading the charge with programs that incentivise community solar with distributed energy sources.

Wood Mackenzie’s 18th Solar and Energy Storage summit is back, in Denver this week. If you can’t make it, don’t worry – we have all the debate and key insight you need to know here on the podcast.

Recorded live on day 1 of the summit, host Sylvia Leyva Martinez talks to four industry leaders in solar and storage to answer these questions:

Can the U.S. solar industry keep up with demand amid trade wars and policy chaos? Discussing this is David Carroll, ENGIE’s Chief Renewables Officer. He warns that policy uncertainty and tariff whiplash are stalling U.S. solar investment. Sylvia and David look at sodium-ion batteries; are they a safer option? Plus, more domestic energy storage is needed amid growing calls for stable tax credit policy to meet growing electricity demand. A must-hear for developers navigating today’s volatile energy landscape.

What about VPPS? Can they scale fast enough to provide a real alternative? Answering this is Sarah Noll, She shares insights on regulatory challenges, customer trust, and tech adoption, showing how the Arizona Public Service is turning grid flexibility into a real growth strategy.

Are storage operators leaving millions on the table because they don’t understand their own batteries? That’s the big question Shyam Srinivasan, CEO of Zitara, answers with Sylvia. He reveals how poor software integration is holding back storage performance. As storage scales rapidly, Shyam stresses the need for better diagnostics and real-time decision tools to optimise revenue, reliability, and resilience - especially in merchant markets.

Finally, Samantha Frisk from Pivot energy sits down with Sylvia to look at models for community solar development. Sam explains how early engagement, local benefits like agrivoltaics, and trusted partnerships can turn sceptical communities into solar advocates - proving clean energy can uplift as well as decarbonise.
