The International Council on Clean Transportation (ICCT) recently released an interesting report title “Evaluation of state-level U.S. electric vehicle incentives”.
Incentives are usually a political mine field, as there are always two sides - those who would like incentives and those who don't. ICCT focuses on how incentives influence sales and, as we all know, if you can grab additional grand or two in state-level incentives, then sales will be higher.
Here we have two graphs showing consumer benefit and new vehicle share for U.S. states - in order by the largest total battery electric and plug-in hybrid electric incentives or by largest total new battery electric and plug-in hybrid electric vehicle shares.
Not every state with high incentives is above average for EV shares. Louisiana probably leads the states with highest incentives, but lowest impact on sales.
An important finding is that non-direct incentives (like carpool lane access) can be a very strong sales stimulus.
