A study by a team at MIT has concluded that roughly 90% of the personal vehicles on the road in the US could be replaced by an electric vehicle available on the market today, even if the cars can only charge overnight. MIT Associate Professor Jessika Trancik, corresponding author of the paper published in Nature Climate , noted that this would more than meet near-term US climate targets for personal vehicle travel. The team spent four years on the project, which included developing a way of integrating two large datasets—one highly detailed set of second-by-second driving behavior based on GPS data, and another broader, more comprehensive set of national data based on travel surveys—to estimate the energy requirements of personal vehicle trips […]
