Laura Holgate on the Promise and Perils of Nuclear Innovation

In energy markets, all eyes are on the Strait of Hormuz. As of March 11, 2026, this vital passage is effectively closed to tanker traffic, stranding almost a fifth of world supplies of crude oil, oil products, and liquefied natural gas.  Yesterday, oil prices retreated sharply on a tweet from US Energy Secretary Chris Wright, claiming that the US Navy had escorted a tanker through Hormuz. That tweet was retracted, and was followed by reports that US intelligence had detected signs Iran had begun placing mines in the Strait.  To help sort through the quickly-changing events in the Middle East and dig into how they impact energy security, we are launching a new, limited series of the Columbia Energy Exchange podcast: the Iran Conflict Brief. To kick off the series, Daniel Sternoff, a senior fellow at the Center on Global Energy Policy, speaks with Mike Knights about what needs to happen in order for oil and gas flows to resume through the Strait of Hormuz. Mike is an expert on Gulf and Middle East security and leads research at Horizon Engage, a strategic advisory firm. For over 20 years he has advised operators and investors in the region of political and security risks. He is also an adjunct fellow at the Washington Institute for NearEast Policy, where he co-founded the Militia Spotlight, focused on Iran-backed proxies. Credits: Hosted by Daniel Sternoff.

Look for the first episode of the Iran Conflict Brief right here in your Columbia Energy Exchange feed.

Since the US-Israeli bombing campaign began in Iran, energy markets around the world have been on edge as the conflict threatens immediate and long-term energy supplies. We've seen major disruptions throughout the Gulf region, with the closure of the Strait of Hormuz and massive price spikes and swings in oil and natural gas.   This is of course exposing serious vulnerabilities across global energy markets and it's putting a spotlight on what's happening in the deeply integrated markets of Russia and China.  Even before the conflict started, Russia's energy sector was struggling under the weight of infrastructure damage inflicted by Ukrainian forces. But now Russia has emerged as an unlikely safety valve for the market, benefiting from the massive supply shortages.  Meanwhile, China finds itself in a precarious balancing act; it is being forced to look at alternative markets for relief and is reportedly reviving discussions around major energy projects, such as the Power of Siberia 2 natural gas pipeline with Russia.  So how is Russia responding to the current crisis? And how is it impacting China, which is particularly exposed to disruptions in Gulf energy flows? How might this crisis change Russia's approach to the European energy market? And is the conflict accelerating a deeper fragmentation — moving toward a world of competing energy blocs rather than a single global energy market?  Today on the show, Jason Bordoff speaks with Erica Downs, Tatiana Mitrova and Sergey Vakulenko about how the crisis in the Middle East is impacting Russia and China and what each country stands to gain or lose. Tatiana is a global fellow at CGEP. She has deep expertise in Russian and global energy markets, including production and pricing. Erica is a senior research scholar at CGEP, where she focuses on Chinese energy markets and geopolitics.  Sergey is a senior fellow at the Carnegie Russia Eurasia Center. Prior to this, he led strategy, innovations, and sustainability at the Russian oil producer Gazprom Neft.  Credits: Hosted by Jason Bordoff and Bill Loveless.

On February 28, the United States and Israel launched a campaign against Iran targeting military infrastructure and the regime's core leadership. Supreme Leader Ayatollah Ali Khamenei and several senior officials died in the attacks, which triggered a leadership crisis and inflamed tensions throughout the Middle East.   In the immediate aftermath, Iran launched extensive barrages of drones and ballistic missiles aimed at Israel, US military bases, ​and other targets in neighboring Gulf states. Energy prices rose sharply. This regional shift carries immediate and enduring consequences for global geopolitics and the stability of international energy flows. ​The outcome of the conflict—and the ultimate fate of the Iranian regime—remains deeply uncertain. Even with these open questions, the trajectory of this escalation will likely redefine the future of Middle Eastern security, global power dynamics, and the world's energy markets. How is the conflict evolving, and how might it end? What are the impacts on Gulf states and what are some of the possible paths forward? And how is this all impacting oil and gas markets across the globe? Today on the show, Jason Bordoff speaks with four experts from the Center on Global Energy Policy—Anne-Sophie Corbeau, Richard Nephew, Daniel Sternoff, and Karen Young—to discuss the escalating conflict and its impact on energy and geopolitics. Anne-Sophie is a global research scholar at CGEP, where she focuses on hydrogen and natural gas. She previously worked as a senior analyst at BP and the International Energy Agency. Richard is a senior research scholar at CGEP and formerly served as the US deputy special envoy for Iran under the Biden administration, where he played a key role in negotiations over the Iran nuclear deal.  Daniel is a senior fellow at CGEP and heads its corporate partnership strategy.  Karen is a senior research scholar at CGEP with expertise in the Middle East focusing on geopolitics, the political economy of Gulf states, and energy policy. The Center on Global Energy Policy at Columbia University SIPA is closely following the escalating conflict in Iran and its implications for US national security, Middle East geopolitics, and global energy markets.

President Trump has aggressively used tariffs as an economic tool, but a US Supreme Court decision on Friday struck down his sweeping tariffs, bringing new uncertainty. The court, in a 6-to-3 decision, ruled that the president had exceeded his authority when he imposed tariffs on nearly every US trading partner last year. President Trump moved swiftly to work around the court by imposing levies using other trade powers. On Saturday, Trump said that he would raise the new global tariff rate to 15%, using a provision in a law that allows him to impose an across-the-board tariff. This measure can only be enacted for 150 days unless Congress agrees to extend it. Trump also said he would use the act to investigate other countries' unfair trade practices, which could result in additional tariffs.  What does the Supreme Court ruling mean for the president's ability to wield tariffs for geopolitical pressure? How will this impact US trading partners and existing trade deals? And what about the impact on the energy sector, from oil and gas to clean energy products?  Today on the show, Jason Bordoff speaks with two researchers from the Center on Global Energy Policy, Richard Nephew and Trevor Sutton, to unpack the ruling. Richard formerly served as the US deputy special envoy for Iran under the Biden administration, where he played a key role in negotiations over the Iran nuclear deal. From 2013-2015, Richard also served as the Principal Deputy Sanctions Coordinator at the US Department of State. Trevor focuses on the intersection of trade, climate, and industrial policy. He leads the center's program on trade and the clean energy transition. Trevor previously served as research director of the Remaking Trade for a Sustainable Future project.

Under the second Trump administration, the US Department of Energy significantly shifted its priorities to align with its "energy dominance" agenda. But one significant point of continuity with the Biden years is a continued emphasis on energy security. Energy security means different things today than it did even a decade ago. It's about competing in the global race for artificial intelligence, reshoring manufacturing supply chains, and keeping the lights on as extreme weather events become more frequent and more destructive. But the administration's efforts to bolster energy availability at a time of surging load growth has included emergency orders to keep coal-fired power plants operating. And it has pulled back funding for new energy transmission projects that it says will not quickly lower energy costs for US consumers.  So when it comes to the administration's energy dominance agenda, what are the trade-offs between security and speed? What does the administration's waning support for renewables and low-carbon industries mean for American clean energy innovation in the coming decades? And how will the US build out new power capacity, including advanced nuclear, quickly and safely? Today on the show, Jason Bordoff speaks to the acting under secretary of energy at the US Department of Energy, Alex Fitzsimmons, about the second Trump administration's energy policy priorities.

The Trump administration has prioritized nuclear energy expansion, aiming to increase US nuclear capacity fourfold by 2050. This nuclear energy resurgence in the US is a rare issue with bipartisan support, and tech companies have poured billions of dollars into sustaining nuclear power plants and building new reactors to supply AI data centers. But accelerating nuclear power could mean changing environmental and safety reviews. And small modular reactors and other innovations in nuclear energy are likely years from commercial readiness.  So is there a way to reinvigorate nuclear energy in the US that's safe and fast? What would that mean for the power sector and the communities that support plants today, and future sites? Are there any signs that new technologies could address the perennial questions around nuclear safety? And what does all of this mean for national security and energy policy? Today on the show, Bill Loveless speaks with Laura S. H. Holgate, Ambassador (ret.) about the state of nuclear energy innovation, safety, and governance. Laura is the president of LSHH International Advisors and a distinguished visiting fellow at the Center on Global Energy Policy. She twice served as ambassador to the International Atomic Energy Agency. She has held multiple positions in and out of government, including vice president at the Nuclear Threat Initiative, special assistant to the president at the White House National Security Council, and a senior official at the departments of Energy and Defense.  Credits: Hosted by Jason Bordoff and Bill Loveless.

As political support for clean energy has waxed and waned over the past twenty years, so has the government's financial backing. In the 2010s, critics pointed to the failed solar startup Solyndra, which the Department of Energy had backed to the tune of half a billion dollars, as a poster child of wasteful spending.  But under President Biden, in addition to major clean energy incentives passed in the Inflation Reduction Act, the DOE's Loan Programs Office borrowing authority grew ten-fold. Now, under a second Trump administration, the tide turned again. The loan office, and clean energy spending, have scaled back significantly. So how has federal support of nascent clean energy technologies evolved? What could be done today to lower energy costs while boosting the reliability of the electric grid? Where is domestic manufacturing headed and how does that impact both energy and national security? And what could be done today to lower energy costs while boosting the reliability of the electric grid?  Today on the show, Jason Bordoff speaks with Jigar Shah to discuss the current state of clean energy investing and innovation. Jigar is the co-managing partner at the clean tech advisory firm Multiplier and co-hosts the Open Circuit podcast. He directed the DOE's Loan Programs Office during the Biden administration. Before that, he co-founded and was the president of the investment firm Generate Capital. Early in his career he co-founded the solar service company SunEdison.

With electricity prices on the rise, the future of our power grid is attracting a lot more attention. Surging demand is at the center of the story, but the power sector is also grappling with supply chain bottlenecks and aging infrastructure – all while trying to balance capacity growth with reducing emissions. This isn't just a technical challenge. Energy affordability and equity are reshaping debates about energy policy, permitting reform, and climate goals.  So, what's really behind rising prices? What are the best ways to balance the need to build capacity with the interests of communities? What role can research play when it comes to steering energy policy? And what lessons can Texas teach us about all of these concerns? Today on the show, Jason Bordoff speaks with Michael Webber about the costs of energy; the challenges of permitting reform; and the need to build more energy faster. Michael Webber is a professor at the University of Texas at Austin. He's the author of multiple books on energy, including Power Trip and Thirst for Power, both of which were adapted into award-winning PBS documentary series. In addition to his academic post, Michael previously served as CTO of the venture fund Energy Impact Partners, and as chief science and technology officer at ENGIE.

From the affordability crisis and the data center boom, to the US government's campaign to reinvigorate the Venezuelan oil market, energy is dominating headlines in unusual ways.  And that's all happening against a backdrop of upheaval in federal energy policy, which started on day one of the second Trump administration. As we begin the new year and head into midterm elections, there's a dizzying number of crucial energy policy issues at play. So what issues are shaping US climate and energy policymaking in 2026? How might upcoming court rulings change things? As high utility bills persist, how is the public responding to changes in energy policy? And what stories or trends are not being told amid all of these important energy storylines? Today on the show, Bill Loveless speaks with reporters Maxine Joselow and Josh Siegel about covering energy and climate policy, and what key stories and trends they're covering in 2026. Maxine Joselow is a reporter for The New York Times where she covers climate policy from Washington D.C. Before joining The Times Maxine covered climate change and the environment for The Washington Post. Earlier, she was a reporter at E&E News. Josh Siegel is an energy reporter for POLITICO, where he focuses on Congress. He also hosts the POLITICO Energy podcast. Previously, he covered the energy beat for the Washington Examiner where he wrote the Daily on Energy newsletter.   Credits: Hosted by Jason Bordoff and Bill Loveless.
