Benefits of Electric Vehicles


Electric vehicles offer significant environmental advantages over conventional gasoline or diesel-powered cars.

  • Reduced Carbon Emissions: About one-third of the nation's greenhouse gas emissions come from transportation ¿ and 60 percent of that is from personal vehicle use. Electric vehicles significantly reduce carbon emissions, even when using electricity generated primarily from coal.
  • Reduced Operating Emissions: The emissions associated with the electric drivetrain of plug-in electric vehicles come from power plants generating electricity to charge the batteries and not from tailpipe emissions. Additionally, electric vehicles emit approximately 66 percent less carbon dioxide (CO2) compared with internal combustion vehicles. CO2 is the principal gas associated with global warming. Use this Vehicle Cost Calculator to compare life cycle emissions of individual vehicle models.
  • Water Quality Preservation: Decreased use of petroleum gasoline and motor oil means fewer spills and pollution to oceans, rivers and ground water.
  • Reduced Noise: In addition to being cleaner, electric vehicles are quieter than gasoline-powered vehicles, resulting in less noise pollution.


Many electric vehicles receive top National Highway Safety Traffic Administration safety ratings. To date, findings have shown that several electric vehicle features maximize safety. For example, electric vehicles tend to have a lower center of gravity that makes them less likely to roll over, electric vehicles have less potential for major fires or explosions and the body construction and durability of electric vehicles enhance vehicle safety in a collision.

Lower Operational Costs

The estimated cost of electricity needed to power a plug-in electric vehicle is about one-third of the cost of gasoline. You can use this Vehicle Cost Calculator to compare lifetime ownership costs of individual models of HEVs, PHEVs, BEVs and conventional vehicles.

Lower Maintenance Costs

The electrical components of plug-in electric vehicles require little to no regular maintenance due to far less moving parts. In hybrids, this leads to less wear and tear of gasoline components.

Tax Incentives

There is currently a federal tax credit that ranges from $2,500 to $7,500 depending on battery capacity of the vehicles being purchased.
