Economic Impacts of Electric Vehicle Adoption

This project examined likely levels of EV adoption in order to estimate the impact of EVs on Hawaii’s economy and to determine the level of opportunity of EV’s as a grid stabilization tool. Researchers have collected Hawaii data on vehicle adoption rates and practices as applied to Hawaii-specific vehicle ownership. Three reports on EV penetration, EV cost comparisons and GHG emissions have been completed and published. The first report evaluated EV penetration rates and provided an assessment of expected EV penetration over time. The results estimate there will be 140,000 EVs on the road in Hawaii by the year 2040 in the reference scenario. To complement the results of the EV-adoption scenarios, EV lifecycle ownership costs were analyzed in the second report. This report assessed the impact of the federal tax credit for EVs and of the benefits of household photovoltaic systems coupled with proposed time-of-use electricity rates for EV owners. The third report estimated GHG emissions of EVs in Hawaii to include comparisons with similar ICE vehicles. In terms of GHG emissions, EVs offer an improvement over ICEs. However, the model that looked at GHG emissions by county showed that HEVs outperform EVs on Oahu because of oil generated electricity while EVs outperform HEVs on the big Hawaii Island because of the high level of geothermal electricity. Researchers are presently working on documenting policies that support EV uptake within the U.S.
