Electric vehicles (EVs) operate by way of an electric motor, powered by a series of rechargeable batteries. The batteries are charged by connecting the vehicle to an electric power source, with many EVs gaining some additional energy stores through regenerative braking. The range of an electric vehicle is limited, generally between 35 and 80 miles, depending on the batteries used, the number of batteries, vehicle weight, weather and driving conditions. This makes EVs most suited to short-distance trips involving many starts and stops, such as airport applications, delivery vehicles, transit and personal use. Electric vehicles can be designed with the comparable speed and power of conventional vehicles.

While electricity is suitable to power a wide range of vehicle types, few battery electric vehicles are available. The major automobile manufacturers have ceased development and production of electric passenger vehicles in favor of hybrid electric vehicles and hydrogen/fuel cell technologies. Available vehicles include some buses and neighborhood electric vehicles (NEVs). Used electric vehicles may be available. Conversion of a vehicle is possible, though the extensive modification and costs can be prohibitive.

Environmental & health benefits: Electric vehicles are zero-emission vehicles in terms of tailpipe emissions. Concerns have been raised regarding the emissions associated with the generation of electricity, particularly from coal-fired power plants. While it is appropriate to consider such life-cycle factors when discussing the environmental and health benefits of electric vehicles, it is important that these factors be compared to the life-cycle emissions and environmental consequences of petroleum extraction, production and distribution. Studies have concluded that recharging electric vehicles using coal-fired power plants would still produce 17 to 22 percent fewer carbon dioxide emissions than gasoline powered cars and the recharging of vehicles using natural gas powered plants would produce 48 to 52 percent fewer carbon dioxide emissions. The disposal of electric vehicle batteries has raised concerns regarding the potential for contamination. Advancements in battery technology and battery recycling are reducing problems associated with vehicle batteries.

Safety characteristics: The primary safety concerns relate to the handling of vehicle batteries during recharging and disposal, as there is the potential for electric shock, as well as contamination and chemical burns from batteries using liquid acid. All high-voltage circuits are marked with warnings to prevent safety concerns.

Economics: Electric vehicles are significantly more expensive than gasoline vehicles. The cost of the vehicle varies depending on the size of the vehicle and the battery technology selected. NEV prices generally range from $6,000 to $15,000. Light-duty vehicles been priced at $15,000 to $40,000. Heavy-duty electric vehicles vary in cost depending on the type of vehicle. Federal tax incentives for electric vehicles and recharging facilities help to defray some costs.


Neighborhood Electric Vehicles (NEVs): Neighborhood electric vehicles (NEVs) are defined as four-wheeled electric vehicles having a maximum speed of 25 mph. The vehicles typically obtain a 30 mile range per charge. NEVs are perfect for short-trip neighborhood operation.  The largest source of gasoline vehicle emissions occurs during short-trip operation.  As electric vehicles, NEVs have zero emissions and thus have the potential to provide significant air quality benefits.  The benefits also include lower cost (average of $6,000 to $12,000), reduced noise in communities, reduced parking pressures (2 or 3 vehicles can fit in a conventional parking space), and low cost to operate and maintain. Several vehicle styles are available, including 2 and 4 passenger models and vehicles with utility, truck-style beds. Effective August 1, 2003, NEVs can be licensed for on-road use in Washington State.


Plug-in Hybrid
Electric Vehicles (PHEVs): In brief, plug-in hybrid electric vehicles (PHEVs) extend the electric capabilities of an HEV so that it can travel some distance solely using battery power. The vehicles have larger battery packs than current HEVs and the batteries can be plugged into a standard outlet for recharging. When the batteries are sufficiently depleted, the vehicle relies on the internal combustion engine. To date, PHEVs have not been commercially produced by original equipment manufacturers (OEMs) but conversions of HEVs have been completed by other groups (See CalCars). PHEVs are often described in terms of the range on which they can travel solely on electric power - common ranges are 20-60 miles. Depending on driving patterns, these vehicles would have substantial improvements in fuel economy over conventional or even hybrid vehicles. For a lot of information on PHEVs and the national campaign to convince OEMs to produce these vehicles, visit the Plug-in Partners Campaign website.


Puget Sound Clean Cities Coalition strategies: Growth of the electric vehicle market has been inhibited as the major automobile manufacturers have cancelled their light-duty electric vehicle programs and the limited number of medium- and heavy-duty options available. Current market development is in the area of NEVs and other small electric vehicles, such as the Tango and the Sparrow, and in vehicle conversions. These vehicles provide a viable and desired option in many applications.

The following strategies will guide the work of the Coalition in this area:

  • Focus on deployment of NEVs, particularly in niche applications.

  • Provide education via website and vehicle displays.

  • For NEVs, coordinate with manufacturers to find dealers and partner with dealers on education.
