The U.S. Department of Energy (DOE) has found that a small electric SUV with 300 miles of range produces 52% fewer life-cycle greenhouse gas emissions than a comparable gasoline vehicle. While emissions from production and distribution of electric vehicles are currently higher than gasoline vehicles, the overall emissions are still lower due to the lack of tailpipe emissions in electric vehicles.
## Electric SUVs vs Gasoline SUVs
The comparison of 2024 lifetime greenhouse gas emissions of small SUVs by the U.S. Department of Energy highlights the environmental benefits of electric SUVs over gasoline-powered ones. Despite the higher emissions from production, electric SUVs emit significantly less greenhouse gases over their lifespan compared to gasoline vehicles.
## Renewable Energy and EV Emissions
The use of renewable energy to power the grid can further decrease emissions from electric vehicles. According to the Union of Concerned Scientists, a majority of Americans already live in areas where electric cars are cleaner than gasoline cars based on local grid emissions. This shift towards renewable energy can make electric vehicles even more environmentally friendly.
## SUVs and Global Emissions
While electric SUVs have lower emissions than gasoline SUVs, SUVs in general are still not the best choice for the environment. The International Energy Agency (IEA) has found that SUVs emit 20% more CO2 compared to cars, regardless of powertrain type. The global SUV market is fueling oil demand and counteracting some of the emissions reductions from higher electric vehicle adoption.
## Efficiency and Impact of SUVs
The inefficiency of SUVs, both in combustion and electric powertrains, is magnified by their heavier weight compared to cars. The increased global sales of SUVs, reaching a record 48% in 2023, are contributing to higher emissions and oil demand. The DOE highlights that smaller SUVs are better for the environment in terms of CO2 emissions, with electric and plug-in hybrid models being the most environmentally friendly.
## Conclusion
Overall, the transition to electric SUVs can significantly reduce greenhouse gas emissions compared to gasoline vehicles. Despite the challenges posed by SUVs in general, the shift towards renewable energy and smaller electric SUV models can help minimize the environmental impact of transportation. The findings from the DOE and IEA underscore the importance of considering both the powertrain type and size of vehicles in reducing emissions and addressing climate change.
