Electric vehicle adoption and energy prices: Empirical evidence from four Nordic countries

While the transport sector accounts for around 25% of the EU's total GHG emissions, the adoption of electric vehicles (EVs) plays an important role in achieving the EU's net zero emissions goal. Alongside subsidies or tax exemptions for EV purchases, energy prices, i.e., electricity price and gasoline price, can also serve as policy instruments to encourage consumers to shift from internal combustion engine (ICE) vehicles to EVs. Using a unique panel of EV registrations at the product-level from four Nordic countries (Denmark, Finland, Norway, and Sweden), this paper investigates how electricity prices and gasoline prices stimulate the adoption of EVs. The results show that gasoline prices have a more statistically significant effect on the adoption of EVs (as a substitute for ICE vehicles), compared with electricity prices. On average, 1% increase in gasoline price would increase the sales of EVs by 0.85% and the effect is larger for EV models with relatively lower purchase cost (where the effect of electricity price is also found statistically significant) and those with less-known brands. Further simulation results show that a 1% increase in the gasoline price would reduce the lifecycle GHG emissions of new automobiles by 0.16%. Our study highlights the importance of energy prices in accelerating EV adoption and mitigating carbon emissions in the Nordic countries.
