Prof. John Fernandez speaks with New York Times reporter Somini Sengupta about how to reduce the climate footprints of homes and office buildings, recommending creating airtight structures, switching to cleaner heating sources, using more environmentally-friendly building materials, and retrofitting existing homes and offices. “It’s going to be a lot easier to reduce carbon emissions in the built environment than almost everything else,” explains Fernandez.
Prof. Danielle Wood speaks with NPR Shortwave co-host Aaron Scott about the future of space sustainability. “I hope that humans pause and note that the actions we're taking now and in the next 10 years really are going to be decisive in the relationship between humans and our planet, and humans and other locations, like the Moon,” says Wood.
In an opinion piece for The Boston Globe, Prof. Christopher R. Knittel explains why electricity bills in Massachusetts can be so high and how to address the issue. “State law requires Massachusetts to cut greenhouse gas emissions relative to 1990 levels by 50 percent by 2030 and by 85 percent by 2050,” writes Knittel. “In short, we need to replace gasoline and natural gas with electricity. But how we price electricity is making this effort to address climate change harder."
MIT researchers have found that by “encouraging strategic EV charging placement, rather than allowing EV chargers to be situated merely due to charging company convenience or preferences” it may be possible to “mitigate or eliminate EV charging problems without the need for advanced technological systems of connected devices and real-time communications, which could add to costs and energy consumption,” reports Carolyn Fortuna for CleanTechnica.
MIT researchers have found that placing EV charging stations in strategic locations and setting up charging systems to initiate charging at delayed times could help reduce the impact of EVs on the electrical grid, reports Michael Schoeck for PV Magazine.
MIT scientists have found that delayed charging and strategic placement of EV charging stations could help reduce additional energy demands caused by more widespread EV adoption, reports Grace Carroll for Fast Company. “Leveraging these two strategies together significantly eliminates any additional energy demands,” writes Carroll, “and can be tailored to specific local conditions to help cities meet their decarbonization goals.”
A new study by MIT researchers finds that strategic placement of EV charging stations and creating systems to help stagger charging times could help reduce or eliminate the need for new power plants to handle the impact of EV charging on the grid, reports Sharon Udasin and Saul Elbein for The Hill. The researchers found that “better availability of charging stations at workplaces could help take advantage of peak power being produced midday by solar energy facilities.”
Senior lecturer Jason Jay speaks with Financial Times reporter Sarah Murray about the positive impact of online sustainability courses. “What it means to put a tax on carbon feels very different for wealthy communities in Northern Europe than it does for people in India,” says Jay. “A global community of learners can challenge things and bring in their own perspectives.”
Carlos Casanovas MS ’14 co-founded X1 Wind, a startup that has developed a floating wind turbine prototype, reports Andrew Paul for Popular Science. “Floating wind is set to play a vital role supporting the future energy transition, global decarbonization and ambitious net-zero targets,” says Casanovas.
Researchers at MIT have predicted that without improvements in hardware efficiency, energy consumption and emissions from autonomous vehicles could be “comparable to that of data centers today,” reports Sarah Wells for Popular Mechanics. “In order to reduce the future carbon footprint of AVs, scientists will need to make the computing systems of AVs, including smart sensors, far more efficient,” writes Wells.
Writing for The Hill, Prof. Yossi Sheffi examines several strategies companies could use to help improve supply chain sustainability, including redesigning last-mile deliveries, influencing consumer choices and incentivizing returnable containers. “Supply chains can be designed to reduce emissions from operations and to reorient their buying behavior in support of carbon emissions reductions,” writes Sheffi.
MIT researchers have developed a new two-step electrochemical process to remove carbon dioxide out of seawater, reports John Fialka for E&E News. The new approach “cuts energy costs and expensive membranes used to collect CO2 to the point where merchant ships that run on diesel power could collect enough CO2 to offset their emissions,” Fialka writes.
Researchers at MIT have discovered what makes ancient Roman concrete “exponentially more durable than modern concrete,” reports Jim Morrison for Wired. “Creating a modern equivalent that lasts longer than existing materials could reduce climate emissions and become a key component of resilient infrastructure,” writes Morrison.
An MIT study has found that the wide spread adoption of self-driving cars could lead to increased carbon emissions, reports Rima Sabina Aouf for Dezeen. “The study found that with a mass global take up of autonomous vehicles, the powerful onboard computers needed to run them could generate as many greenhouse gas emissions as all the data centers in operation today,” writes Aouf.
Boston Metal, an MIT startup, has developed a way to generate steel without releasing carbon dioxide emissions, reports Catherine Clifford for CNBC. The company “plans to begin construction of a demonstration steel plant in 2024 and a commercial sized plant in 2026,” says Boston Metal CEO Tadeu Carneiro.
