Fueling Electrification: The Impact of Gas Prices on Hybrid Car Usage
CEPR
2024.02.06
We use micro-level data on fuel consumption, mileage, and travel mode to study plug-in hybrid drivers‘ response to fuel prices. When fuel prices rise, plug-in hybrids reduce fuel consumption more than gasoline and diesel cars. They do not reduce their mileage but increase electric recharging, without evidence of habit formation. As the share of kilometers driven in electric mode by plug-in hybrids is only half the official test cycle value, fuel prices are effective in improving the environmental performance of these vehicles. Considering the choice of fueling versus recharging, we estimate that drivers value time at €15 to €41/hour.
