**Electric Cars**



An __electric car__ is simpily a car that is powered by electricity rather than gasoline. An electric car uses electric motors and motor controllers for propulsion instead of what most other cars use which is the internal combustion engine. Electric cars are commonly powered by on-board battery packs.

 * Scientists are trying to make electric cars more environmentally friendly and less costly than gasoline run automobiles. Electric vehicles generally cost less to own, operate and maintain than combustion powered vehicles. They also contribute to reduced dumping of engine oils into the environment and reduced U.S. reliance on foreign oil. Electric vehicles emit not pollutants so their much better for the environment and better for everyone's respiratory health. These vehicles are also more reliable. They don't need fluids such as engine oil, anti-freeze or transmission fluid, so they require less maintainence and are less likely to leak. Electric vehicles are very useful if you're not trying to spend lots of time and money on your car and want to be environmentally safe.
 * Electric vehicles prevent the carbon cycle from being disrupted. Gasoline ran automobiles release gases and fossil fuels into the atmosphere which disrupt the carbon cycle. Electric cars use a fuel cell, or generator. A fuel cell is a specialized form of battery that combines hydrogen and oxygen in a chemical reaction that produces electricity and water vapor. So when an electric car is being used it is not releasing any harmful gases into the atmosphere. The carbon cycle isnt harmed by the electric cars and they are much better for the atmosphere.
 * Yes electric cars are a viable solution to protecting the biosphere. Electric cars emit virtually no greenhouse gases into the air which means they run much cleaner than other vehicles do. Greenhouse gases contribute to the depletion of the ozone layer that has led to global warming. Electric cars that run on batteries alone produce no pullution at all and thus are very environmentally friendly.
 * Yes there are some possible consequences to the environment. As newer research comes out scienctists are saying that the amount of energy used by coal fired power stations to create the electricity to recharge electric vehicles makes them half as efficient as diesel cars.

Electric cars can travel for about hundred miles before needing charged. The batteries generally need charged overnight and there is a gauge that tells you how much power you have left. Electric cars can also drive very fast. They have been clocked to go from 0 to 100 miles per hour in nine seconds! This is because electric motors have a very high torque which allows them to accelerate quickly.
