Tens of millions of delivery vans and semi trucks move around the clock to keep supply chains humming. These medium- and heavy-duty vehicles make up more than 25 percent of transportation emissions in the US — even though they only make up 10 percent of all vehicles on the road. We need to electrify medium and heavy-duty vehicles to meet our climate goals. But, how do we build and operate the charging infrastructure to power them? That charging network is exactly what our guest, TeraWatt Infrast...

Mar 02, 2022•52 min•Ep 50•Transcript available on Metacast There are 46,000 public EV charging stations across the United States. But with 32% of charging stations down at any given time, maintaining them is a big challenge for the industry. Minimizing charger downtime isn’t easy – differences in manufacturers, network providers, and utilities can mean wide variation in hardware or software between stations. That complexity can make fixing technical problems a challenge. And that's exactly what our guest, ChargerHelp! Co-founder and CEO Kameale Terry, i...
Feb 09, 2022•47 min•Ep 49•Transcript available on Metacast Electrifying cars and trucks is an essential part of decarbonizing mobility. But there's another vital piece in the race to zero-emissions transportation: public transit. Transit tech is emerging as one of the most exciting areas in the climate space. It's made up of companies using technology to get people out of their cars and onto shared vehicles like vans, buses, and trains. And the need has never been greater. When the pandemic threw public transportation systems around the world into turmo...
Dec 21, 2021•55 min•Ep 48•Transcript available on Metacast Starting in the 1960s, the United States became a world leader in building large-scale geothermal power plants. That changed in the mid-2000s with the fracking boom. Drillers turned their attention to oil and gas. And as wind, solar and batteries got cheaper, bankers and developers put their money into those resources. Today, geothermal development around the world has flatlined. But a small legion of clean energy entrepreneurs is working quietly in the background on innovations that could catal...
Dec 07, 2021•1 hr 1 min•Ep 47•Transcript available on Metacast There are a lot of nuances to the way people perceive our warming planet. But media coverage of the issue is often catastrophic, scientifically dense, or framed exclusively around politics. So how do we talk about climate in a way that resonates across diverse groups of people? That's what our guest, Alex Blumberg, kept asking himself. Alex is an acclaimed audio journalist. He’s the co-founder of Gimlet Media and host of the Spotify climate solutions podcast How to Save a Planet . Alex has pushe...
Nov 22, 2021•43 min•Ep 46•Transcript available on Metacast The United States recently surpassed 100 gigawatts of installed solar capacity, enough to power nearly 20 million homes. But to decarbonize the power grid by 2035 and meet growing demand, the Department of Energy estimates that we'll need 1,000 gigawatts of solar capacity, providing 40% of the nation's electricity in just 15 years. That means, on average, we'll need to install solar at quadruple the rate we did in 2020. We can't achieve that growth without creative new ways to install solar in a...
Oct 26, 2021•47 min•Ep 45•Transcript available on Metacast Ninety percent of Americans want to see more renewable energy on the grid. But two-thirds of them can't directly access wind and solar — because they don't own their rooftop, can't afford the upfront cost, or can't get it from their monopoly utility. That’s where our guest, Arcadia Founder & CEO Kiran Bhatraju, comes in. “We started Arcadia to give everyone access to clean energy. It was as simple as that,” says Bhatraju. “This is a very closed, balkanized industry. And so the core idea was to b...
Sep 28, 2021•50 min•Ep 44•Transcript available on Metacast When it comes to climate tech companies, there's only one name that's known around the world: Tesla. Tesla has arguably been the defining climate tech success story of the 21st century, driving demand for electric vehicles and becoming one of the world's most valuable companies. When people think of the person behind Tesla, they think of Elon Musk. But Musk wasn't there from the very beginning — he was an early investor in the company, and didn't become CEO until five years after its founding. M...

Jun 15, 2021•38 min•Ep 40•Transcript available on Metacast Africa is becoming a dynamic market for clean, distributed energy. All across the continent, solar, batteries, generators, and microgrids are giving people energy cheaply — and providing greater reliability in a region where many central grids remain unreliable. But that dynamism can come at a cost. Systems are often complex. They lack standards. And it’s often difficult for buildings and businesses to manage and integrate them in concert with an incomplete grid. And that's where our guest, Ugwe...
