Electric vehicle (EV) efficiency compared to gasoline cars varies significantly by region, primarily due to differences in ambient temperature and the regional electricity grid’s carbon intensity.
Regional Temperature Effects on EV Efficiency
- EV efficiency is sensitive to ambient temperature because battery performance and cabin climate control demands change with temperature.
- In colder regions such as the Upper Midwest of the United States, EVs consume about 15% more energy annually compared to milder regions like the Pacific Coast. Similarly, hot areas like the Southwest also experience increased energy consumption for cooling needs.
- Cold climates can reduce EV range substantially. For example, a Nissan Leaf’s average range can fall from 70 miles on mild Pacific Coast days to less than 45 miles in the coldest Upper Midwest days.
- These temperature-driven efficiency losses do not affect gasoline cars as much, making EVs relatively less efficient in extreme cold or hot climates.
Regional Electricity Grid Impact on Emissions and Efficiency
- The greenhouse gas emissions associated with EVs depend heavily on the regional grid mix. Areas with higher carbon intensity (like parts of the Upper Midwest) produce more emissions per kWh than regions with cleaner grids (like the Pacific Coast).
- This grid effect means that while EVs generally have lower emissions than gasoline cars, the environmental benefits vary regionally, and in some high-emission grid regions, the advantage can be reduced.
Summary
- EVs are generally more efficient than gasoline cars in regions with moderate temperatures and clean electricity grids.
- EV efficiency and range decrease and associated emissions increase in colder or hotter regions and in areas with carbon-intensive grids.
- Therefore, specific regions with extreme temperatures or fossil-fuel-heavy electricity generation make EVs less efficient and environmentally advantageous compared to gasoline cars, affecting adoption and use patterns.
These regional factors highlight that EV efficiency and environmental impact are not uniform but depend critically on local climate and energy sources.
