A new catalyst for the smart home: electrify everything
Visions for the energy-smart home of the future haven’t panned out. In the mid-2000s, the internet-enabled consumer dashboard was going to be the thing that revolutionized energy in the home. Even Google and Microsoft got in on the action – and then shut down their energy dashboards when no one was using them.Then came the smart thermostat, pioneered by Nest. Many hoped the rise of smart thermostats marked the start of a wave of technology adoption that would enable millions of energy-aware homes. They have been helpful for demand response programs, but the gadget-centric model hasn't yet unlocked a smart home revolution.But today, there's a new backdrop that is creating more urgency for the grid-interactive home: electrification. As we electrify the economy and build more variable renewables, we need buildings to help balance the grid. And after decades of futuristic visions that never materialized, are we finally at a moment when the smart, grid-interactive home is emerging in a meaningful form?This week, we dug into that question with Canary Media Senior Reporter Julian Spector. Read Julian’s piece on grid-interactive homes here as part of Canary Media’s week-long coverage of the smart home space.For a full transcript, click here.

The greasy truth behind sustainable aviation fuels
Canary media senior reporter Maria Gallucci recently took a pretty unconventional road trip – shadowing a truck driver as he drove around New Jersey, sucking grease, beef tallow, and used cooking oil out of dumpsters behind airports and restaurant chains. This grease will soon be turned into a sustainable aviation fuel known as hydroprocessed esters and fatty acids, or HEFA. With hydrogen and batteries still not ready to move our airplanes, the airline industry is relying on cooking grease to decarbonize. How clean – and how scalable – is it? Maria Gallucci joins us to explain.

The autonomous car bubble has popped
Five years ago, venture investors, tech companies and automakers were pouring tens of billions of dollars into driverless cars. Tesla, General Motors, Lyft, Uber, and Google's Waymo were promising large fleets of robotaxis with fully autonomous vehicles by the turn of the decade. In 2017, Ford took a big swing. The company invested $1 billion in Argo AI, a startup developing level-four driverless systems. Later, VW entered the partnership. The automakers promised to make a fully autonomous car by 2021. But in October of last year, VW pulled out of the partnership. Ford said it would shut down the driverless car program, taking a $2.7 billion loss. So how did we get to a point where a promising startup valued at $7 billion is being written off by automakers? And what does it say about the viability of fully-autonomous cars?Journalist Ed Neidermeyer says Ford's shutdown of Argo AI was due to inflated expectations – which exposed a mismatch in business models.“I think it's very easy to look at this and say, ‘shutting down Argo AI was an admission that this technology doesn't work…or was a scam. And you look out on social media and people are taking that lesson away – and I think that's the wrong lesson.”This week, we speak with Ed about the real lessons behind the setbacks for autonomous cars: the mismatch between our fantasies and the reality of the technology.Full transcript hereThe Carbon Copy is supported by FischTank PR, a public relations, strategic messaging, and social media agency dedicated to elevating the work of climate and clean energy companies.

The make-or-break moment for America’s energy transition
America enters 2023 faced with two opposing realities: greenhouse gas emissions are going up, but the opportunity to slash those emissions has never been better.Heat-trapping gasses in the U.S. rose again last year, according to the Rhodium Group. Even though renewables outpaced coal on the grid, emissions climbed in the buildings, heavy industry, and transportation sectors.Passage of the Inflation Reduction Act could reverse that trend over the next decade. The law, which was the result of years of political pressure and behind-the-scenes dealmaking, devotes nearly $370 billion to domestic clean energy deployment. It could cut emissions by 40% by 2030.But now the real work begins.On this week’s episode of The Carbon Copy, Jigar Shah and Katherine Hamilton join host Stephen Lacey to talk about the new era for climate solutions deployment in America. The three former co-hosts reunite for some real-talk about the stakes ahead for implementing the IRA.The Carbon Copy is supported by FischTank PR, a public relations, strategic messaging, and social media agency dedicated to elevating the work of climate and clean energy companies.

The great electrician shortage
To decarbonize our economy, we need to electrify everything. That means installing millions of heat pumps, EV chargers, electric water heaters, and rooftop solar panels. But there’s one big problem: finding the electricians to make it happen. Electricians across the country are flooded with demand – and just as demand is skyrocketing, the field is also continuing to age out. This week, in a special collaboration with Grist, guest contributor Emily Pontecorvo tries to answer the question – where are all the electricians? And can we train enough to meet our climate goals?

Gas stations vs utilities: battle for the future of charging
We want your feedback! Fill out our listener survey for a chance to win a $100 Patagonia gift card.Join us on November 30 for a live, virtual episode of Climavores. Come ask a question about food, nutrition, and eating for the climate.The age of the electric vehicle is coming, and it’s going to transform more than just the auto industry. EVs are also set to remake the fueling industry. But who will own the electric charging future?That is the question that journalist David Ferris, reporter for POLITICO’s E&E news, started asking himself a couple years ago. When he started to look into it, he found a simmering tension that is turning into an all-out clash between two pillars of the American energy economy: the electric utility and the gas station.For over a century, gas stations have been a prominent feature of our car-centric landscape. Meanwhile, the provision of electricity has long been the domain of utilities. The EV is bringing these two titans of the energy industry into conflict for the first time, and the battle over who will sell those electrons is already starting to get nasty. You can read Ferris’ story on the contested future of EV charging here.

A reality check on corporate sustainability
We want your feedback! Fill out our listener survey for a chance to win a $100 Patagonia gift card.Join us on November 30 for a live, virtual episode of Climavores. Come ask a question about food, nutrition, and eating for the climate.There’s no doubt that corporations are thinking differently about climate risk and action. But are they making real progress?This week, we have two conversations on the murkiness of corporate sustainability. We’ll talk with Siduja Rangarajan, a senior investigative data reporter, about the creative accounting that is inflating the emissions reductions of large companies. She and journalist Ben Elgin recently dug through 6,000 climate reports – and found that the world’s biggest companies may be failing to account for 24 million cars worth of emissions.We’ll also hear from Joel Makower, co-founder of GreenBiz Group and co-host of the GreenBiz 350 podcast. He’s been covering corporate sustainability for nearly three decades. We talk about what is actually making an impact in corporate sustainability – and what is still holding it back.

The Ike Dike: the biggest civil engineering project in US history
As the cost of living with hurricanes grows, coastal cities across the country are starting to ask the trillion dollar question: what can we build to protect ourselves, and how much are we willing to pay?This week, producer Alexandria Herr takes us to Texas, where the largest civil engineering project in U.S. history may soon put those questions to the test. The Houston area is a sitting duck for a hurricane that scientists say could cause an environmental and economic catastrophe. But the $31 billion “Ike Dike,” approved this summer by the House and Senate, would help protect the region. Will it be enough to prevent disaster? Guests:
