Zero Emissions Vehicles

DOA Goes Electric

DOA is doing its part to lower state greenhouse gas emissions and support Executive Orders 80, 246 and 271 along with 2021 energy legislation. Learn more about greenhouse gas emissions.


Zero Emission Vehicles, also known as ZEVs, are vehicles that do not directly emit exhaust gas or other pollutants. ZEVs are battery powered and must be plugged in to be recharged (fully electric). Hybrid vehicles use both gas and electricity to operate and have both plug-in and non-plug-in options. Traditional gas vehicles are sometimes called ICE vehicles because they use Internal Combustion Engines (ICE) to operate.

Why Switch?

According to the Environmental Protection Agency, the greenhouse gas emissions associated with a ZEV over its lifetime are lower than those from an average gasoline-powered vehicle, even when accounting for manufacturing and electric charging. Lower greenhouse gases and fewer exhaust fumes means cleaner air and a cooler planet. The transportation sector contributes to 30% of all greenhouse gas emissions in the U.S., making transportation the single largest contributor to climate change. 

Charging Electric Vehicles

Electric car ranges vary from about 100 miles up to 350 miles, and for users the primary concern is charging. There are three levels:

  • Level 1: This is the electricity that is available from the outlets in your house. It is roughly 120 volts. Charging this way is extremely slow (17-20 hours).
  • Level 2: Many houses also have 240-volt outlets to run clothes dryers and stoves. You can buy a home charging station and plug it into such an outlet. Chargins will take four to five hours using this method  
  • Level 3:  Many EVs offer a fast charge feature, usually as an option at the time of car purchase, allowing the battery to be charged at Level 3, or 440 volts — much faster than home charging (40 minutes). However, few of these fast chargers are available now.

Motor Fleet ZEV Plan EO 80 Updates 

  • The fiscal year (FY) 2022-23 MFM replacement list identified 144 vehicles eligible for ZEV replacement in the next fiscal year and 504 vehicles eligible for hybrid replacement in the next fiscal year. 
  • MFM has proactively ordered the largest ZEV order in fleet history for 75 Chevy Bolts. This order has not yet been delivered.
  • Motor Fleet retooled the state vehicle procurement contract to secure more cost-effective ZEV and hybrid options. As a result of the new contract, the state fleet will standardize around hybrid sedans where ZEV sedans are not feasible.
  • Hybrid vehicles make up over 67% of MFM total vehicle purchases in FY 2022-23 as of October 2022.  
  • As of spring 2022, new funding has been approved for DOA to deploy chargers in Deck 75. Funds will provide infrastructure for 73 EV charging stations in Parking Deck 75 and assist with upgrading electrical infrastructure.

The Triple Bottom Line: Economic, Environmental and Social Considerations

ZEV advantages

All-electric vehicles (ZEVs) run on electricity only. They are propelled by one or more electric motors powered by rechargeable battery packs. EVs have several advantages over conventional vehicles:

  • Energy efficient: EVs convert over 77% of the electrical energy from the grid to power at the wheels. Conventional gasoline vehicles only convert about 12%–30% of the energy stored in gasoline to power at the wheels.
  • Environmentally friendly: EVs emit no tailpipe pollutants, although the power plant producing the electricity may emit them. Electricity from nuclear, hydro, solar, or wind-powered plants causes no air pollutants.
  • Performance benefits: Electric motors provide quiet, smooth operation and stronger acceleration and require less maintenance than internal combustion engines (ICEs).
  • Reduced energy dependence: Electricity is a domestic energy source.

ZEV disadvantages

  • Driving range: EVs have a shorter driving range than most conventional vehicles — although EV driving ranges are improving. Most EVs can travel more than 100 miles on a charge, and some can travel in excess of 200 or 300 miles depending on the model.
  • Recharge time: Fully recharging the battery pack can take 3 to 12 hours. Even a "fast charge" to 80% capacity can take 30 minutes.
  • Batteries for EVs are designed for extended life, and a study by Department of Energy’s National Renewable Energy Laboratory suggest these batteries may last 12 to 15 years in moderate climates and eight to 12 years in severe climates. However, these batteries are expensive, and replacing them may be costly if they fail.
