CSE FACT SHEET

The transportation system is the largest source of climate-altering U.S. greenhouse gas emissions, making it critically important to accelerate the adoption of electric vehicles (EVs). 

The Center for Sustainable Energy (CSE), a national nonprofit that designs and administers state, local and utility EV and EV charging incentive programs across the U.S., answers some frequently asked questions about EVs and EV policy.

Key EV Facts

  • Transportation is the largest source of U.S. greenhouse gas (GHG) emissions (U.S. EPA, 2020).
  • Since 1990, GHGs for transportation have risen 6.6% while GHGs for electricity generation have fallen 21% (U.S. EPA, 2020).
  • Over 2.9 million plug-in hybrid and battery electric vehicles have been sold in the U.S. since 2010 (Argonne, 2022).
  • Battery electric vehicles make up 3.4% of light-duty vehicles sold in the U.S. When you add hybrid and plug-in hybrid vehicles, EVs now surpass 10% of light-duty vehicles sold. (U.S. Energy Information Administration, 2022).
  • An average EV owner can expect to save $9,000 in fuel costs and $4,600 on maintenance over the 200,000-mile lifetime of an EV (Consumer Reports, 2020).
  • Pollutants from internal combustion engine vehicle tailpipe emissions have been linked to heart disease, stroke and cancer (U.S. Department of Transportation, 2015).
  • There are over 116,000 public charging ports (Level 2 and DCFC) at nearly 46,000 stations across the U.S. (Alternative Fuels Data Center, 2022).

Frequently Asked Questions

Q: What are the benefits of EVs?

Electric vehicles are far cleaner than traditional gas-powered cars and trucks. Since EVs require electricity from the grid, the environmental benefits of EVs vary according to how a state supplies its power grid. But averaged across the U.S., and looking solely at greenhouse gases, an EV is equivalent to a gas-powered vehicle that gets 88 miles per gallon. EVs in states with cleaner power grids, such as California, Iowa, Kansas, and elsewhere, are far cleaner. (Clearing the Air on EVs’ Climate Impact)

  • The Alternative Fuels Data Center takes a national average of the power grid and shows that the average EV emits 3,932 pounds of CO2 equivalent per year. That's compared with 11,435 pounds of CO2 equivalent a typical gasoline-powered vehicle emits in a year.
  • GHGs are just a fraction of the pollution that internal combustion engine vehicles create. Pollutants such as small particulate matter (PM2.5), sulfur dioxide (SO2), nitrous oxide (NOx) and Volatile Organic Compounds (VOCs) are far more dangerous to human health. EVs eliminate tailpipe emissions of these pollutants, reducing premature deaths substantially. EVs also save the equivalent of $8,600 per 150,000 miles of travel based on a reduction in PM2.5 alone.

EVs also save drivers money. EV drivers can expect to save up to $1,000 per year and $9,000 over the lifetime of an EV (200,000 miles) on fuel costs alone compared with driving a typical gas-powered car. Exact savings depend on where and how an EV driver charges and on the cost of gasoline.

Because EVs are simpler and have fewer moving parts, drivers can also expect to save $4,600 on repairs over the lifetime of the vehicle. Consumer Reports finds that over the first 50,000 miles, the average gas-powered car requires $1,411 in maintenance while the average EV requires $577.

Q: Why are EV incentives needed?

To protect all living things from the worst impacts of climate change, improve the health of Americans breathing harmful pollutants, and catch up to global competitors, the U.S. needs to rapidly transition its light-duty vehicle fleet to EVs. This transition is happening far too slowly. As efforts in Norway and other countries have shown, EV incentives greatly speed up the transition to clean vehicles.

EV incentives have multiple benefits:

  • They lower the cost of EVs, which helps more Americans afford them, and send a market signal to automakers.
  • They drive demand for charging infrastructure, which in turn speeds up EV adoption.

Q: Why do we need incentives for publicly available EV charging infrastructure?

The majority of current EV owners charge at home, but to support mass adoption of EVs, including by people who can’t charge at home or at work, the U.S. will need to build hundreds of thousands of charging stations.

Publicly available EV charging inspires new drivers to switch to EVs by providing a visible answer to the “where do I charge” question. Public EV charging stations also promote equitable access to EV ownership by making it possible for people who rent or live in multi-family housing, like apartments, to charge an EV.

With at least $5 billion in federal infrastructure funds available for EV charging through the bipartisan Infrastructure Investment and Jobs Act (IIJA) its National Electric Vehicle Infrastructure Formula Program (NEVI), states have an unprecedented opportunity to kick EV adoption into high gear.

Q: What’s the range of an EV and where can they be charged now?

The range of EVs has been increasing. The median range of BEVs was 234 miles in 2021 – a 104% increase over the median range of 2018 BEVs. Although many Americans cite range anxiety as a barrier to EV adoption, U.S. drivers on average drive only 29 miles per day.

There are three main kinds of EV charging stations in use:

  • Level 1 charging stations are cost-efficient and are comprised of a standard 110-volt outlet and typically used at home. However, Level 1 charging stations are slow, adding on average about 3-6 miles of range per hour. A full charge can take 24 hours.
  • Level 2 charging stations are higher power, require a 220-volt outlet and are frequently in commercial settings and, increasingly, at home as well. Level 2 stations are much faster, adding 18-28 miles of range per hour and can fully charge an average EV in about 8 hours. Level 2 charging stations can be networked – that is connected via the internet to a charging provider’s monitoring system or a utility – or non-networked. Utilities may provide EV rates for connected chargers.
  • DC Fast Charging (DCFC) stations are the highest-power, fastest-charging stations available and are typically found along major travel corridors. A 50 kW DCFC (the smallest size) can add about 200 miles of range (a full tank for many EVs) in about an hour. Automakers and charger manufacturers are working to make this even faster and certain EVs can work with higher power DCFCs. The largest capacity DCFC are 350 kW, and although only certain EVs can work with high power DCFCs, the speed of charging is improving every year.

As of September 2022, there were 45,875 public EV charging stations in the U.S. with a total of 116,800 ports, including:

  • Level 2: 93,312 ports
  • DCFC: 23,506 ports

For context, there are approximately 115,000 gas stations in the U.S.

Q: What are the different types of EVs?

There are three types of EVs in the U.S. These EVs are passenger cars, sport utility vehicles (SUVs), and other kinds of medium-duty and heavy-duty vehicles. Data below is from the Alliance for Automotive Innovation.

  1. Plug-in hybrid electric vehicles (PHEVs) have powerful enough electric motors and sufficient battery capacity to be driven like a true electric vehicle and can be plugged in to charge their batteries. There are about 765,000 PHEVs on the road in the U.S. Examples include the Toyota Prius Prime.
  2. Battery-electric vehicles (BEVs) are what most people consider “electric vehicles” or EVs. There are just over 1.38 million BEVs on the road in the U.S. The most popular is the Tesla Model 3. Most BEVs run solely on electricity from batteries.
  3. Fuel cell electric vehicles (FCEVs) convert hydrogen fuel into electricity that is used to power electric motors that move the vehicle. They work much like PEVs, but are fueled by hydrogen instead of needing to be plugged in to charge. There are about 10,000 FCEVs on the road in the U.S.

The U.S. Department of Energy’s Alternative Fuels Data Center (AFDC) compares the different technical approaches of different types of EVs and provides detailed information and infographics.

Q: What EVs are available? What are planned?

As of September 2022, 32 BEV and 34 PHEV models were for sale in the U.S. – with more models from major automakers expected on the way.

General Motors (GM) became the first U.S. automaker to announce plans to end all production of gas-powered light-duty vehicles by 2035. GM plans to invest $27 billion in vehicle electrification over the next five years and plans to offer 30 new EV models by mid-decade. Other major automakers have announced plans to electrify large portions of their fleets and these plans would lead to over 100 EV models available by the end of 2024.

Analysis by CSE using its patent-pending Caret® Platform shows that action to promote EVs and EV infrastructure is necessary to achieve energy and climate goals, save consumers money, and reduce health impacts of fossil fuel use, especially for those most harmed by pollutants.
