This presentation was given at the Behavior, Energy and Climate Change 2021 Conference.
Dr. Brett Williams, Senior Principal Advisor for Electric Vehicle Programs, presented findings based upon the open-source EVS-33 paper focused on PHEVs.
- Identifies and rank-orders characteristics of consumers most highly enabled by the federal tax credit (FTC) to adopt an EV, informing outreach and incentive design.
- The importance of the FTC was found to be increasing over time, providing evidence that it was too early to start phasing out the FTC.
- FTC influence was found to decrease for those with particularly low income, indicating that the benefit should not depend on tax liability.
- FTC influence increases for lower-priced EVs, indicating the benefit could be made more cost-effective if limited for luxury vehicles and/or increased for non-luxury vehicles.
- Evidence also supports keeping the FTC incentive amount large and bringing it closer to the point of sale.
