Pollution is an ever-widening problem in the world today that cannot be easily solved. Many methods have been developed to reduce pollution, but almost none of them has been proven effective in cars. Alternative methods of fuel such as ethanol, hydrogen, natural gas, and even electricity (batteries), provide a sure-fire way of eliminating harmful emissions from cars. Perhaps most important, alternative fuel sources can resolve this concern not only efficiently, but also cost-effectively.

It is true that in today's modern world, people care less and less about the environment, and governments are just as guilty by their indifference in controlling the matter of pollution. A survey by the California Energy Commission found that last year alone in California, people

range. Since natural gas takes up more space than gasoline, fuel capacity of a normal car's tank is reduced drastically. The only pro to offset this downside, is that natural gas has just about the same energy content as gasoline (Hendren).

Unfortunately, there is a downside to this long carbon chain. Because of its chemical makeup, gasoline doesn't fully burn during combustion. According to a study done by the U.S. Department of Energy, it found that the amount of harmful emissions that are expelled into the air, such as carbon monoxide, nitrogen oxides, and other ozone depleting chemicals, that are byproducts of a car's internal combustion, are enough to cause a theoretical green-house effect ("Replacement"). That is not the only problem with gasoline. Many other environmental hazards occur during the process of drilling for oil and petroleum. Oil spills cause millions of dollars worth of damages to plant and animal life, and also take countless years to clean up.

Another source of alternative fuel that is widely in use today, is natural gas. Natural gas has recently become a very popular in the heating of homes and industries, because of its abundance in the United States and its low cost. Natural gas is mostly composed of methane, which is a naturally occurring gas in the atmosphere.
