Does air pollution increase electric vehicle adoption? Evidence from U.S. metropolitan areas, 2011–2018
A publication in the Journal of Environmental Economics and Policy by a team of economists including UHERO’s Coffman, Hayashida, and La Croix shows that changes in local air pollution within U.S. metropolitan areas are associated with changes in consumer purchases of new EVs. The authors find a positive association between PM2.5 pollution and BEV adoption, and a negative […]

Read MoreEV driver characteristics: Evidence from Hawaii
Electric vehicles (EVs) offer an opportunity to dramatically decrease greenhouse gas emissions within the transport sector if fueled by renewable energy. Hawaii had been early-on considered an ideal place to launch new EVs because of the limited driving range of its island geography. Though it ranks second in new EV registrations per capita in the […]
Read MoreIntegrating Renewable Energy with Time Varying Pricing
With increasing adoption of intermittent sources of renewable energy, effective integration is paramount to fully realizing societal benefits. This study asks the question, how valuable is residential real-time pricing (RTP) in comparison to time-of-use (TOU) rates to absorb increasing sources of intermittent renewable energy? We couple a detailed power sector model with a residential electricity […]
