Efficiency of Electric Vehicles
Electric vehicles are more efficient-and thus generally less polluting than internal combustion vehicles for a variety of reasons. First, because the electric motor is directly connected to the wheels, it consumes no energy while the car is at rest or coasting, increasing the effective efficiency by roughly one fifth. Regenerative braking schemes--which employ the motor as a generator when the car is slowing down-can return as much as half an electric vehicle's kinetic energy to the storage cells, giving it a major advantage in stop-and-go urban traffic.
Every major automaker in the world is now investing in electric vehicle development as well as improvements in less critical technologies such as those underlying car heaters and tires. The resulting advanced components will be the building blocks for very clean and efficient vehicles of the future, but in the meantime many of them are finding their way into internal-combustion vehicles.
Price Factors
Although automakers worldwide have spent perhaps ＄ 1 billion on electric vehicles during the 1990s, in the context of the industry as a whole this investment is relatively small. The auto industry spends more than ＄ 5 billion a year in the U.S. alone on advertising and more than that on research and development. And oil companies are spending about ＄10 billion in the U.S. this decade just to upgrade refineries to produce reformulated low-emission gasoline.
One crucial factor in determining the success of electric vehicles is their price-a figure that is still highly uncertain. General Motors's newly introduced EVI is nominally priced at ＄ 33,000; Solectria sells its low-volume-production electric vehicles for between $30,000 and ＄75,000, depending on the battery configuration. （Nickel-metal hydride batteries capable of carrying the car more than 320 kilometers add nearly ＄ 40,000 to the price of a lead-battery vehicle.） The adversarial nature of the regulatory process has encouraged opponents and proponents to make unrealistically high or low estimates, so it will be impossible to tell just how much the vehicles will cost until they are in mass production.
The cost of batteries （and fuel cells） will probably always render electric vehicles more expensive to purchase than comparable gasoline vehicles. On a per-kilometer basis, however, the cost of an electric and internal-combustion vehicle should eventually be about the same. Fuel for electric vehicles is inexpensive, maintenance is minimal, and it appears that electric motors last significantly longer than gasoline engines. Taking into account the cost of air pollution, greenhouse gases and other market externalities （that is, factors that society at large must now pay for） would tip the scale in favor of electric vehicles in many circumstances.
