Prof. Jessika Trancik speaks with Bloomberg reporter Kyle Stock about the importance of scrappage programs, especially those that incentivize electrifying the current fleet of vehicles in the United States. “At any given point in time, you care about the composition of the fleet,” says Trancik. “Funding programs that would help turn over the fleet more rapidly makes a lot of sense.”

Principal Research Scientist Emre Gençer speaks with The Independent reporter Louise Boyle about natural hydrogen and its potential as a future renewable energy source. “There is a ‘mismatch’ where natural hydrogen is being discovered and where it could be used, which would require massive investments in completely new infrastructure,” says Gençer. “I think it will be part of the solution but we need to take it with a grain of salt.”

Postdoctoral associate Milan Klöwer shares how large conferences can impact air travel and personal carbon footprints, reports Sydney Johnson for KQED. “Flying is one of the sectors where there are enormous inequalities,” says Klöwer. “The people that earn the most [money] fly the most, and therefore have personal carbon footprints that are thousands of times larger than the poorest people on the planet. There is a responsibility for people to understand that problem about how they are personally emitting.”

A study co-authored by research scientist Evan Fricke found that “extinctions and declines in habitat [of migratory birds] have dramatically reduced the long-distance dispersal of seeds,” reports Liam Drew for The Atlantic. “There have been really strong declines in long-distance seed dispersal as a result of the massive loss of big animals from the ecosystems,” says Fricke.

Prof. Kerry Emanuel speaks with Living on Earth host Jenni Doering about the future of extreme weather forecasting. “We have to do a much better job projecting long term risk, and how that's changing as the climate changes so that people can make intelligent decisions about where they're going to live, what they're going to build, and so on,” says Emanuel. “We need better models, we need better computers, so that we can resolve the atmosphere better, we need to make better measurements of the ocean below the surface, that's really tough to do.”

Cipher News editor Amy Harder spotlights the MIT Renewable Energy Clinic, a new course developed by Prof. Larry Susskind aimed at training students to be mediators in conflicts over clean energy projects. Harder notes that the course is focused on creating “collaboration that may slow down projects initially by incorporating more input but ultimately speed them up by avoiding later-stage conflicts.”

As MIT’s fall semester was starting, President Sally Kornbluth spoke with Ben Wildavsky, host of the Higher Ed Spotlight podcast, about the importance of incorporating the humanities in STEM education and the necessity of breaking down silos between disciplines to tackle pressing issues like AI and climate change. “Part of the importance of us educating our students is they’re going to be out there in the world deploying these technologies. They’ve got to understand the implications of what they’re doing,” says Kornbluth. “Our students will find themselves in positions where they’re going to have to make decisions as to whether these technologies that were conceived for good are deployed in ways that are not beneficial to society. And we want to give them a context in which to make those decisions.” 

Roofscapes Studio, an MIT startup co-founded by Olivier Faber MArch ’23, Tim Cousin MArch ’23 and Eytan Levi MArch/MSRED ’21, transforms rooftops into greenspaces as part of an effort to combat climate change and provide green spaces in cities, reports Kim Willsher for The Guardian. The team is looking to add, “wooden platforms fixed across the sloping panes to create roof gardens, terraces and even walkways,” in Paris to help prevent the city from overheating. 

Prof. John Fernández, director of the Environmental Solutions Initiative, speaks with Aynsley O’Neill and Jenni Doering of NPR’s Living on Earth about steps homeowners and renters can take to reduce the risk of wildfires impacting their homes. “The most important thing is to reduce the fuel that’s available between your house and the beginning of the forest, reducing the amount of objects that could ignite,” says Fernández. “That includes outdoor furniture [or] any plastic material.” 

Researchers at MIT have developed a conceptual design for a system that can efficiently produce “solar thermochemical hydrogen,” reports Xinhua. “The system harnesses the Sun's heat to directly split water and generate hydrogen -- a clean fuel that can power long-distance trucks, ships, and planes, while in the process emitting no greenhouse gas emissions.”

Graduate student Kaylee Cunningham speaks with CBS Boston about her work using social media to help educate and inform the public about nuclear energy. Cunningham, who is known as Ms. Nuclear Energy on TikTok, recalls how as a child she was involved in musical theater, a talent she has now combined with her research interests as an engineer. She adds that she also hopes her platform inspires more women to pursue STEM careers. “You don't have to look like the stereotypical engineer,” Cunningham emphasizes.

WBUR reporter Daniel Ackerman spotlights Sublime Systems, an MIT startup working to develop “construction-ready, emissions-free cement.” Ackerman explains that: “Sublime’s new approach uses electricity instead of heat. That means the process can be powered with renewable energy rather than fossil fuels. The method also prevents carbon dioxide from escaping the carbon-rich limestone during combustion.”

Quaise Energy co-founder Carlos Araque BS '01 MS '02 speaks with PBS Energy Switch host Scott Tinker about the future of geothermal energy. [Geothermal is “truly everywhere so it’s not a resource uncertainty, like there is with oil and gas, there’s always heat, but the technological gap prevents us from getting to it,” says Araque. These gaps “are the one caveat in unlocking this resource for everybody.”

Dan Stack PhD ’20 speaks with TechCrunch reporter Tim De Chant about his startup Electrified Thermal Solutions, which is developing electrified firebricks to help decarbonize building materials.  

Data from the Clean Investment Monitor, a new project from MIT’s Center for Energy and Environmental Policy Research and the Rhodium Group, shows that President Biden’s 2022 Inflation Reduction Act has impacted both consumer and corporate spending. “The data show that in the year since the climate law passed, spending on clean-energy technologies accounted for 4 percent of the nation’s total investment in structures, equipment and durable consumer goods — more than double the share from four years ago,” writes Jim Tankersley for The New York Times.
