MIT researchers have analyzed the role of long-duration energy storage technologies and found that large storage systems have the potential to lower electricity prices in a carbon-free grid by up to 40%, writes Eric Roston for Bloomberg. 

A study by researchers from MIT, Yale and Purdue finds that leaving the camera on during video meetings is a contributor to carbon dioxide emissions, reports Hannah Smothers for Vice. “Just one hour of videoconferencing or streaming, for example, emits 150-1,000 grams of carbon dioxide (a gallon of gasoline burned from a car emits about 8,887 grams), requires 2-12 liters of water and demands a land area adding up to about the size of an iPad Mini,” the researchers write.

Prof. Jessika Trancik speaks with the BBC Newshour about her new study analyzing the dramatic decline in the costs of lithium-ion batteries. Trancik explains that the reduced price, “opens up markets for electric vehicles for more people. The battery makes up a substantial portion of the total cost of an electric vehicle and the fact that costs have fallen by 97% over the last few decades means that these cars are no longer just for the wealthy.”

Graduate student Caroline White-Nockleby discusses her new white paper that explores the regional impact of the decline in coal production. “Employment in the [coal] industry has decreased from around 3,800 jobs to around 2,800 direct jobs in the past five years,” says White-Nockleby .”They also have a big role in the tax base. Coal companies pay taxes on the value of the coal itself that’s underground, and they also pay property taxes.”

“What we need to do, especially as we move more towards intermittent energy that we can’t predict as well as the output of thermal power plants is to keep adding to that resiliency,” says Robert Stoner, deputy director of the MIT Energy Initiative. Stoner discussed the recent failures of Texas’ power grid and what New England can learn from these events on WBUR’s Radio Boston.

Prof. Jessika Trancik speaks with The Hill reporter Rachel Frazin about her research that demonstrates people can save more than 30% in emissions by switching to electric vehicles. “One can see an immediate reduction in greenhouse gas emissions, even with today’s power grid and today’s power supply. It’s a really important step to electrify as many vehicles as possible, and quickly,” says Trancik. 

Prof. Jessika Trancik speaks with Jesse Remedios of WBUR about her new study that identifies locations where electric vehicle charging stations would have the most impact and help increase the adoption of electric vehicles. “It's important to make sure that chargers are placed where people can charge without having to delay their activities,” Trancik says. 

New York Times reporter Brad Plumer spotlights a new study by Prof. Jessika Trancik that finds “new chargers on residential streets, as well as high-speed charging stations along highways, would go a long way to supporting an electric-vehicle boom.” 

Mashable reporter Sasha Lekach spotlights a new study by MIT researchers that finds installing more charging stations close to residences and in locations that match where people naturally stop, would help increase usage of electric vehicles. The researchers found that “this helps to make charging more accessible while drivers are going about everyday activities.”

A new study co-authored by MIT researchers examines the carbon emissions associated with video conferencing, reports Rachel Moss for HuffPost. The researchers found “just one hour of video conferencing or streaming emits 150-1,000 grams of carbon dioxide.”

A new study co-authored by MIT researchers quantifies the carbon costs of working from home, reports Devin Coldewey for TechCrunch. “In order to build a sustainable digital world, it is imperative to carefully assess the environmental footprints of the Internet and identify the individual and collective actions that most affect its growth,” the researchers explain.

MIT researchers have developed an online interactive tool aimed at helping consumers quantify the costs of buying an electric or gas-powered vehicle. The tool demonstrates how electric vehicles may initially be more expensive, but are often cheaper in the long-run, reports Veronica Penny for The New York Times. Prof. Jessika Trancik notes that she hopes the tool will “help people learn about how those upfront costs are spread over the lifetime of the car.”

A series of papers by MIT researchers demonstrates how their design for a new nuclear fusion reactor should work, reports Oscar Schwartz for The Guardian. “Fusion seems like one of the possible solutions to get ourselves out of our impending climate disaster,” says Martin Greenwald, deputy director of MIT’s Plasma Science and Fusion Center.

Forbes contributor Dipka Bhambhani spotlights a new study by MIT researchers that examines the causes of cost overruns and delays in nuclear power developments, and finds they could have been “averted by building plants in factories and then installing them on site.”

Financial Times reporter Henry Sanderson spotlights Prof. Donald Sadoway’s work developing new battery chemistries that would allow batteries to store energy for longer than six hours.
