Internal combustion engine vehicles [are responsible for the vast] emit most [majority of] urban pollutants. [that plaguing urban areas today]

These emissions [are directly responsible for many of] degradethe air quality [problems faced] in major urban areas.

Electric vehicles produce little or no pollution directly; most of the pollution associated with their use is created at the power plant that provides their electricity.

While studies of the pollution-reducing ability of electric vehicles in California are quite favorable, they cannot be applied to the rest of the world as a whole.

We can expect similar results for the United States, namely, that while electric vehicles produce much less carbon monoxide and hydrocarbons, they use similar levels of nitrogen oxides and carbon dioxide, and increased levels of sulfur oxides.

Not all pollutants related to electric vehicles arise from the generation of electricity.

While electric vehicles may not always hold an outright advantage in terms of pollution reduction, they allow for more control over the pollution that is generated.

The use of electric vehicles would allow even further decreases in auto emissions over time because only about 10,500 power plants will have to be monitored, maintained, and upgraded as opposed to the over 100 million private automobiles.

Because so many tradeoffs in local versus global pollution are involved, it is impossible to say with certainty that electric vehicles provide the best short term solution to transportation related pollution.


Your comments and suggestions are appreciated.

Internal combustion engine vehicles emit most urban pollutants.

These emissions degrade the air quality in major urban areas.
