Setting world records. Combing through warehouses of old electronics. Seeding the Chinese solar industry from afar. This is the life of Martin Green, a professor at the University of New South Wales in Sydney and the director of the Australian Centre for Advanced Photovoltaics. Green’s work on solar panel design made the modern solar industry possible: 90% of solar panels made last year were based on his designs. He’s still going strong, too, regularly breaking new records in the pursuit of the perfect solar panel. This week on Zero, Akshat Rathi sits down with the man many call “the godfather of solar” to hear firsthand how it happened, the next record he wants to break and whether solar panels are destined for space.  Read more:  Making Solar Panels Is 'Horrible' Business.

Cleantech is hard. Farming is harder. This week, Akshat Rathi visits entrepreneurs doing both.  GroGrace in Singapore and Jungle in Paris are two vertical farming companies taking agriculture indoors, and trying to grow crops efficiently and profitably. While the technology to do this has been around since the 1990s, the business model has yet to be perfected, and several other vertical farms have closed down or laid off staff this year. As the world faces rising energy prices, water scarcity, and hotter temperatures, can the entrepreneurs in Paris and Singapore avoid the problems of their compatriots?  Read more:  Akshat Rathi’s reporting on Singapore’s cleantech scene: Singapore’s Building Technology It Needs for a New Climate Era - Bloomberg  From AppHarvest to AeroFarms, Funding Is Drying Up for AI-Run Vertical Farms - Bloomberg Heat, War and Export Bans: Global Food Threats Are On the Rise   Another tale of the Dutch exporting their vertical farming know-how: Saudi City of Future Enlists Dutch Help to Grow Crops in Desert - Bloomberg  Listen to related episodes of Zero:  The world's food system needs a radical rethink - interview with George Monbiot Zero is a production of Bloomberg Green.

Trillions of dollars are needed to fund the climate transition, with both the private sector and governments required to contribute. Australia’s answer is the Clean Energy Finance Corporation (CEFC), the world’s largest green bank.  Established by the government in 2012 with an initial funding of A$10 billion ($6.5 billion), it was tasked with financing green projects and ambitious Australian climate startups at a time when large-scale investments in things like wind and solar were still seen as too risky for most private banks. Despite early efforts by opposition parties to abolish the bank, over the past 10 years it has made itself an essential part of Australia's energy transition and, in June, received an extra A$20.5 billion to help the country meet its target of 82% renewables by 2030.   This week on Zero, Akshat Rathi sits down with CEFC chief executive officer, Ian Learmonth, to learn how this huge amount of money will be spent, why the CEFC had so many enemies early on, and what kind of innovative startups and clean-tech projects the organization is looking to fund.

The concept of a “carbon footprint” began as a distraction from Big Oil: get people to focus on their own actions rather than the impact of large emitters. Oil companies come up with PR campaigns all the time, but the carbon footprint took off because it taps into a question we keep coming back to, can our choices lower emissions? If so, how? And if they don’t, why bother? This week, Akshat is joined by Kira Bindrim, the editor of Bloomberg Greener Living, which focuses on consumer choices, to talk about what she’s noticed in a year of editing stories about products, misconceptions, and how much people just love to read about electric cars. Plus, we break down her carbon footprint.

This week, a visit to the energy startup trying to replace coal with a very cheap battery. Form Energy has attracted nearly $900 million in investments and is building its first manufacturing facility in the US. Its big innovation relies on rust. Really. The materials scientists at Form have taken the same process that’s a symbol of time slowly passing and turned it into electricity. It’s one of the first big bets that batteries could help push the grid closer to running without fossil fuels altogether. You can read more about Form Energy and see what the battery looks like here.
