Why should all cars be powered on alternative fuels?
The leading alternative fuels right now are bio fuels (mainly bio diesel and ethanol), hydrogen (both fuel cell and combustion), electric and CNG/LPG. However, Compressed Natural Gas and Liquid Propane Gas are not much better than oil because they are still fossil fuels. We should change because oil is severely flawed. Like all fossil fuels, oil is only available in a limited, rapidly depleting supply. Because the carbon in fossil fuels has been out of the Carbon Cycle for millions of years, the Cycle has adjusted. Then, when the carbon is released into the environment, it causes many problems like global warming, acid rain and pollution in general. The American economy would generally benefit. Most (if not all) of the alternative fuels would be readily available in the US. They would keep money from leaving our country, the fuel costs would stay lower and more stable and jobs would be created. The cost would really depend on the fuel.
