Alternatives to oil, coal, and natural gas only provide a small proportion of the electricity needed to power U.S. factories, businesses and homes. However, as worries increases over the high costs and environmental effects of reliance on limited natural resources, more Americans are looking to alternative energy for the future. The burning of these fuels causes severe air pollution and thus contributes to the “greenhouse effect.” This enormous amount of consumption will be the ultimate cause of the scarcity of oil in the future and of environmental pollution. If people do not develop any substitutes to burning fossil fuels in the next few decades, people will experience a new and large-scale energy crisis. In the U.S., there is a high demand for gasoline. However, if people start to use alternatives fuel vehicles, it can lower the demand of oil, which will in turn minimize the oil-dependence and potential environmental problems. Jim Motavalli, the editor of E: The Environmental Magazine, once said in his book Forward Drive, that “At long last, technological wizardry is being applied to the automobile, with the result being a new generation of cleaner cars. The gasoline engine represents yesterday’s solution to our transportation problems” (Motavalli, XIII) Today, hybrid cars are the best solution for America’s addiction to fossil fuels because they use clean energy to power vehicles, have compatible performance compared to conventional gasoline and diesel cars, and provide economic incentive for buyers.
People believe that carbon dioxide (CO2) is one the causes of greenhouse effects. Scientists claim that CO2 accumulates in the atmosphere and traps the heat from getting out of the Earth. Thus, global temperature is increasing. As the problem of global warming and greenhouse effect become more evident, Americans have to find more renewable and cleaner energy sources
