The advantages of electric automobiles .
Based on recent discoveries in the fields of environmental pollution and automobile research, conclusions can be made that electric cars are more beneficial to the environment and with progress will be more beneficial to the consumer as well. With the invention of the electric automobile, environmentalists have been given an alternative solutions to the many problems caused by carbon monoxide which is a by product of gas engines.
With the invention of electric vehicles that are powered by electric batteries, automobiles are being made to have all the capabilities of gas-powered cars but with less harmful exhaust. According to EPRI (Electric Power Research Institute) electric vehicles are considered to be "97% cleaner than gasoline powered cars."(SDGE) This even takes into account the emissions from the power plants that generate the electricity to recharge EV batteries. It is much more efficient to control air pollution from a single power plant rather than from many individual automobiles. Electric vehicles with cleaner air as a byproduct, will improve the air quality especially in heavily congested areas such as New York and Los Angeles. With more and more EV's on the road, SMOG will be less of a problem and the environment, ex. trees and plant, will not have to work as hard to clean the air; slowly the planet might be able to recover from the centuries of damage caused by gas-powered automobiles and many other polluting machines.
Motor vehicles emit several pollutants that EPA classifies as known or probable human carcinogens. Benzene, for instance, is a known human carcinogen, while formaldehyde, acetaldehyde, 1,3-butadiene and diesel particulate matter are probable human carcinogens.(Lee, 17) Studies are underway to determine whether other toxic substances are present in mobile source emissions. For example, EPA and industry are investigating whether oxygen-containing fuel additives such as methyl tertiary butyl ether (MTBE) cause any adverse health effects.
