The 100-ton device that can stop blackouts in the renewables era: Bottlenecks Series
In April, Spain suffered a nationwide blackout that lasted nearly a full day. It was a traumatic event for one of Europe’s fastest adopters of solar power, tripling capacity in just five years. The outage sparked a big question: Was solar to blame? And what will it take to avoid blackouts in the renewables era? Bloomberg Green’s Laura Millan joins Akshat Rathi on Zero to unpack the lessons from the Iberian Peninsula and the technologies that could make such blackouts a thing of the past.

Build small, grow fast: Can small modular reactors live up to the hype?
Electricity demand is soaring, and some think the answer isn’t building bigger, but smaller. That’s the idea behind small modular reactors (SMRs): take a large-scale nuclear plant that’s hard to build, and shrink it down to something that’s more manageable, cheaper and easier to replicate. Instead of one huge nuclear plant, you build 10 small ones. Right now these kinds of small modular reactors are in the startup phase, with only two in commercial operation in Russia and China. So how viable is the business for these small modular reactors? And will SMRs ever become a scaled up solution for our energy needs? Rachel Slaybaugh joins Akshat Rathi on Zero to discuss.

How rich countries can build cheap nuclear power again
Electricity demand is booming, and it’s not just because of artificial intelligence. So much so that many are ready to revisit the idea of nuclear power. Microsoft signed a $16 billion deal to reopen the Three Mile Island nuclear plant to power their data centres for the next 20 years. But developed countries haven’t built more than a handful of new reactors in decades. When they have tried, the cost of those nuclear plants and the time to build them has been extraordinary. Will this renewed interest yield different results? Nuclear scientist and partner at venture capital firm DCVC Rachel Slaybaugh joined Akshat Rathi on Zero to discuss how these new dreams of growing nuclear power can become a reality.

How a bunch of students beat big polluters in the world's highest court
In 2019, a group of law students from Pacific island nations set in motion a case that made it to the world’s highest court: The International Court of Justice. The students wanted answers to two important questions: what responsibility do countries have to stop climate change? And if countries don’t stop polluting, will they have to pay for the damages? Now the ICJ has delivered its verdict, and it seems like a huge win for the climate. But is it? Laura Clarke, chief executive officer of legal non-profit ClientEarth, joins Akshat Rathi on Zero to discuss.

Trump’s immigration policy is a nightmare for climate tech
Everywhere you look, it seems like bad news for climate tech. Investments are down, the US government has cut incentives and startups are running out of cash. But venture capitalist Vinod Khosla is still bullish, even though the One Big Beautiful Bill cut an estimated $500 billion in green spending. This week on Zero, Akshat Rathi speaks with Khosla to find out when we can expect to see fusion, whether he’s reconsidering investing in the US and why he still thinks the best clean tech is yet to come.

How to fight against Trump’s attack on clean energy
The One Big Beautiful Bill Act cuts almost $500 billion in US clean-energy spending, just as the country was starting to get serious about its climate goals. Some say the country is acting like a petrostate, waging war against clean energy. Others are more sanguine and believe that the US will stay the course in the long term. This week on Zero, Akshat Rathi is joined by Jigar Shah, a clean energy expert and former head of the Department of Energy's Loan Programs Office, to make sense of the bill’s impacts, and whether it’s as bad for climate as it seems.

Trumponomics: Will Trump’s bill trigger a ‘Big, Beautiful’ energy crunch?
This week, we explore how the legislation’s attack on renewable energy may push up electricity bills and damage US competitiveness in AI. The tax credits in President Joe Biden’s sprawling Inflation Reduction Act were introduced to help the US keep up with rising electricity demand by making clean power sources cheaper. But now the big bill has changed all that, and an executive order issued days after its passage suggests his war on renewables isn’t over yet. Joining host Stephanie Flanders to discuss this dramatic turn of events are guests Ethan Zindler, head of country and policy research at BloombergNEF and previously climate counselor to US Treasury Secretary Janet Yellen, and Bloomberg lobbying and influence reporter Emily Birnbaum.

Why militaries can no longer ignore climate change
The world’s militaries are incredibly polluting, collectively accounting for some 5.5% of global emissions. Western economies are now gearing up for a big expansion of their militaries, with members of the North Atlantic Treaty Organization (NATO) agreeing to increase defense spending to 5% of their gross domestic product by 2035. That will commit trillions of dollars more to an enormously carbon intensive industry, unless militaries can find a way to reduce their emissions. This week on Zero, Akshat Rathi asks retired Lieutenant General Richard Nugee, author of the UK Ministry of Defence’s climate change report: Can warfare go green?

The UK now has a state-owned clean-energy champion. Can it succeed?
When the UK handed the Labour party a parliamentary majority last July, it promised to build a new state owned energy company called Great British Energy. It's almost exactly one year since its creation, and GB Energy now has a budget of £5.8 billion to get the organization off the ground. It sounds like a lot of money, but is it? And what exactly will the organization do with all of it? On Zero this week, Akshat Rathi spoke to Dan McGrail, interim CEO of GB Energy, to find out the answers.

What a venture capitalist does when climate tech loses its shine
Climate tech is not the hot investor thesis it once was a couple of years ago. After several record breaking years, and billions of dollars being poured into climate startups, venture capital investments are way down. This week on Zero, Akshat Rathi speaks with Mike Schroepfer, who runs Gigascale Capital, a venture firm focusing on climate investments, and used to be Meta’s chief technology officer. Schroepfer shares his views on the current investment climate, the danger of funding cuts to US research, and why demand for AI will prompt a new wave of energy innovation.

Have China’s emissions finally peaked?
When exactly China’s emissions peak will make a big difference to the fate of the planet. That moment has come, according to Lauri Myllyvirta, co-founder of the Centre for Research on Energy and Clean Air. A combination of factors – including a huge deployment of renewables and electrification of transport – has put China’s emissions into a structural decline. This week on Zero, Akshat Rathi asks Myllyvirta how confident he is that this really is a peak? What’s behind the decline in emissions? And how will the trade war with the US affect China’s climate and energy policies in the years to come?

How Australia’s natural resources will shape global emissions
Australia is in a unique place when it comes to the energy transition. It is the world’s largest exporter of coal and a leading exporter of gas, yet has set a target to reduce emissions by 43% and have 82% renewable electricity by 2030. It is also caught juggling relations between the US, its military ally, and China, its biggest trading partner — as the two superpowers fight over trade. It is an unenviable challenge for Prime Minister Anthony Albanese, who has just been voted back into the office with an impressive new majority and also wants Australia to host the COP31 climate summit in 2026. This week, David Stringer, Bloomberg Green's managing editor in Asia, joins Zero to unpack Albanese’s full agenda and what his re-election means for Australia’s climate ambitions.

Can Carney transform Canada from climate laggard to leader?
This week, Canadians elected Mark Carney, leader of the Liberal party, to be their prime minister. Carney is a newcomer to politics, but is well known in international finance and climate circles, running both the Bank of Canada and the Bank of England, and founding the Glasgow Financial Alliance for Net Zero (GFANZ). Canada is far from reaching its legally mandated goal to achieve net zero by 2050, and has one of the highest emissions per capita of anywhere in the world. Now Carney has been elected, can he translate his international climate leadership into domestic policy, or will climate fall by the wayside as he fortifies Canada against a trade war with the US?
