Studies by researchers at MIT have found “that shifting to electric vehicles delivers a 30% to 50% reduction in greenhouse gas emissions over combustion vehicles,” reports Tom Krisher for Associated Press. According to Prof. Jessika Trancik, “electric vehicles are cleaner over their lifetimes, even after taking into account the pollution caused by the mining of metals for batteries,” writes Krisher.
Prof. Jessika Trancik speaks with Popular Science reporter Charlotte Hu about the impact of electric vehicles on the environment. “There’s definitely a number of different modes of transport that need to be addressed and green modes of transport that need to be supported,” says Trancik. “We really need to be thinking holistically about all these ways to reduce greenhouse gas emissions.”
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.”
MIT researchers have constructed a mini city to test to safely test algorithms designed for autonomous vehicles, reports Mashable. “The idea of the mini city is that we have lots of cars going at the same time and we can actually test out new algorithms in a safe environment,” says graduate student Noam Buckman.
Researchers at MIT have developed an autonomous vehicle with “mini sensors to allow it to see the world and also with an artificially intelligent computer brain that can allow it to drive,” explains postdoctoral associate Alexander Amini in an interview with Mashable. “Our autonomous vehicles are able to learn directly from humans how to drive a car so they can be deployed and interact in brand new environments that they’ve never seen before,” Amini notes.
Prof. Jessika Trancik speaks with Bloomberg reporter Kyle Stock about the carbon impact of electric vehicles. “On average, your emissions are substantially lower if you go for the full electric [vehicle],” says Trancik. “But we could probably think of extreme edge cases where a hybrid is just as good.”
Research scientist Bryan Reimer and his colleagues have been collecting data from vehicles with driver-assist technology for the last seven years, writes Pete Bigelow for Automotive News. “We desperately need to understand the denominators, the frequency of events and the behaviors underlying them to understand the benefits and limitations of automated and assisted driving,” says Reimer. “We need to understand which aspects are working well and which ones need refining.”
A study by MIT AgeLab research scientist Bryan Reimer found that drivers using autopilot were “more likely to look away from the road once the system was on,” reports Aarian Marshall for Wired. “With automation comes an inherent new level of complexities. There are lots of risks and lots of rewards,” says Reimer.
Prof. Jessika Trancik speaks with Forbes contributor Peter Cohan about the carbon emissions associated with gas, hybrid and electric vehicles, and the site she and her research group developed to allow consumers to compare personal vehicles against climate change mitigation targets. “In most locations, compared to [gas-powered vehicles], EVs produce emissions savings greater than 30%,” says Trancik. "Most savings are greater depending on the geographic location, the electricity supply, and the vehicle model.”
Writing for the Financial Times, Prof. Carlo Ratti explores how coordination between ride-hailing services can benefit cities by reducing traffic and carbon emissions. “Imagine a world in which, instead of wavering between Uber, Lyft or a regular taxi, we could open a single app that figures out which service is closest and most affordable,” writes Ratti.
Daily Beast reporter Miriam Fauzia writes that MIT researchers have developed a new way to create carbon fibers that are stronger and lighter than steel, using leftover waste from crude oil processing. “The new findings could usher in an age of heavy-duty cars that consume less fuel thanks to their decreased weight,” writes Fauzia.
Hill reporters Saul Elbein and Sharon Udasin spotlight how MIT researchers have developed a way to make lightweight fibers for possible use in the bodies of cars out of the waste material from the refining of petroleum. “The ‘heavy, gloppy’ leftovers from the petroleum refining process could become a key ingredient in making electric vehicles lighter, less expensive and more efficient,” they write.
