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.

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.

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.

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.

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.

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.

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.

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?
