Roughly 42% of energy-related carbon emissions come from householdsâour cars, water heaters, furnaces, dryers, cooktops and where we get our energy. Stephen Pantano, head of Market Transformation for Rewiring America, joins Good Clean Energy to explain how replacing fossil-fueled machines at home with electric ones is a critical and achievable strategy for reaching net zero emissions in the U.S.
Covered in this episode:
[2:30] The mission of Rewiring America[4:02] âThe perfect household is all-electricâ[5:19] Using heat pumps to heat and cool your home[9:57] Cooking without gas[12:45] Heating your water with a heat pump [14:42] Drying your clothes with a heat pump[15:32] The economic incentives to electrify your home[20:49] Where Rewiring America comes in[23:22] The challenges of rolling out the rebate programs[24:51] The roadblocks to electrifying America[26:03] The 1 billion devices that need to be upgraded[29:59] Where an individual can make the most impact[31:22] A vision for 2035For show notes and a full transcript, head to the episode page.

Cement accounts for 8 percent of global CO2 emissions. The production of one ton of Portland cement â the kind most commonly used â results in one ton of CO2 released into the atmosphere. And since cement is exceptionally cheap and the most massively produced man-made material in the world, those emissions are going to grow. âIn a do-nothing scenario, emissions from cement are projected to increase 50 percent between now and 2050,â says Dr. Leah Ellis, co-founder and CEO of Sublime Systems.
Ellisâ company is producing low-carbon cement by replacing the traditional high-temperature, fossil fuel, combustion-driven kiln with an electrochemical approach that operates at ambient temperature and uses renewable electricity.
âI like to say Sublime is the electric vehicle of cement making.â
[3:18] How Ellisâ background in chemistry led to making carbon-free cement[5:51] Why defining cement by its performance is important[7:48] The basics of cement[9:29] The outrageous amount of cement produced annually[11:29] How Sublime Systems produces cement with fewer carbon emissions[18:06] The ability to compete economically[23:04] Scaling up Sublimeâs operations[26:37 The leaky tap analogy to understand the climate crisis[29:53] A vision for the cement industry in 2035

Anu Khan, Deputy Director of Science and Innovation at the nonprofit Carbon180, joins Good Clean Energy to discuss the ins and outs of removing carbon dioxide from the atmosphere.
Throughout the industrial era, weâve emitted roughly 2 trillion tons of carbon dioxide, 1 trillion of which is still in the atmosphere today and is going to continue to cause warming for an extended period of time. Most of that warming is caused by the burning of fossil fuels for energy, and reducing emissions is crucial to keeping global warming below the goal of 2°C. But the challenge doesnât end there. Thatâs where carbon dioxide removal comes in.
While there are a few ways to actually remove the carbon dioxide and thereâs the question of who should really pay for it, itâs clear that CO2 removal is necessary. âIt's fundamentally a climate justice solution, and carbon removed anywhere benefits everyone globally,â Khan said.Covered in this episode:
[3:28] The role of carbon in our planet[5:42] Why we need carbon removal in addition to clean energy[7:38] The difference between carbon capture and carbon removal[11:28] How much CO2 we need to remove from the atmosphere[15:11] The suite of carbon removal solutions[16:38] Who pays for carbon dioxide removal[21:04] The personal carbon offset market[22:27] The potential for cost-effective CO2 removal[25:05] The leading approach to direct air capture[28:57] The most compelling argument for CO2 removal[32:19] A vision for 2035For show notes and a full transcript, head to the episode page.

What are the biggest challenges to widespread adoption of electric vehicles? Cost, range anxiety and charge time. Kedar Munipella, CEO of TAE Power Solutions, joins the show to talk about how his company solves for all that. Working with a radical new approach to power distribution, battery performance is optimized and charge time is reduced. That, in turn, will make EVs less expensive.For show notes and a full transcript, head to the episode page.

Industrial heat accounts for 25% of global energy consumption to make products ranging from steel to cement to paper and so many other things you've probably never thought about. Itâs a huge chunk of our climate problem â and itâs uniquely hard to decarbonize. Thatâs where John OâDonnellâs company, Rondo Energy, steps in. Rondo is using hot bricks to store energy as heat. And since industrial processes need energy in the form of heat anyway, itâs a no-brainer. âIt happens to be the worldâs most efficient way of storing energy,â OâDonnell said of his technology.

About 90 percent of the world's trade is transported by sea, on giant polluting cargo ships that burn particularly dirty oil. Last week, the International Maritime Organization, the UN body responsible for regulating global shipping, set a new CO2 reduction target for the industry to get to net zero by 2050. To help us make sense of the transition that will need to happen, Maria Gallucci, a clean energy reporter at Canary Media, joins Good Clean Energy to talk about new green fuels and technologies for the industry.

Paul Eremenko, co-founder and CEO of Universal Hydrogen, believes that there is a relatively simple way to solve the aviation industryâs carbon emissions problem. Todayâs sustainable fuels arenât really all that sustainable, he says, and electric planes, while great in theory, donât scale. That leaves one obvious choice for Eremenko: green hydrogen. âThere is a very significant sort of low-hanging fruit opportunity with no significant tech risk to put hydrogen in service and solve in one fell swoop half of aviation emissions problems by 2035,â Eremenko says.

As a former chairman of the U.S. Nuclear Regulatory Commission with both a law background as well as a PhD in applied physics, Richard "Dick" Meserve is uniquely qualified to speak on the future of both nuclear fission and fusion in the U.S.
âWe have a huge challenge in confronting climate change, and it's my view that we need to marshal all the resources we can to address it," says Meserve. "And that obviously includes a heavy emphasis on renewables, but you need a backup. You need firm power as a supplement to renewables. And nuclear is a natural component of that.â

Jamie Alexander is working to make capitalism compatible with a climate-safe world. Alexander is the director of Drawdown Labs, a branch of the nonprofit organization Project Drawdown that works directly with corporations to think beyond net zero and use their existing social, political, financial, and employee power to accelerate climate solutions at an unprecedented scale. "The more that companies can identify what their superpower is and use that to help the world get closer to our climate goals â that's where I think capitalism and climate change are going to meet in the middle.â

The U.S. power grid is old. On average, itâs 40 years old â a quarter of the grid is 50 years old and there are parts that are 100 years old. And as we strive for a net-zero future, that grid is going to play a massive role, says Christina Hayes, Executive Director of Americans for a Clean Energy Grid, a coalition focused on preparing the U.S. grid for new renewable and clean energy sources.
