Transportation PEEC focuses its transportation research mostly on behavioral approaches to more energy-efficient personal mobility. Such topics include boosting public transportation and translating car fuel efficiency into dollars saved. PEEC has also analyzed U.S. policies to reduce gasoline consumption and invented a device to recycle otherwise wasted heat from car motors into electricity.
