An Examination of Feasible Alternative Fuels Industry

Demand for gasoline has been the driving force in utilization and depletion of crude petroleum, which is a non-renewable resource. In recent years, tendencies have just begun to, at times, favor alternative fuels to power autos. Many possible alternative fuels exist, certainly not without their drawbacks. These alternatives include, but are not limited to, various batteries coupled with solar power, alcohols, gasohols, and both liquefied and gaseous natural gas, as well as hydrogen. As mentioned above, drawbacks do exist; the chief drawbacks being cost of adaption / implementation, engineering, and cost of the fuels themselves. As stated by many a chairman of petroleum companies, alternative fuels have limited applications and too many economic disadvantages, (Derr, 30).
"Although alternatives to gasoline may have some very limited niche applications in efforts to reduce air pollution, they have too few environmental advantages and too many economic disadvantages to justify the high expectations that some regulators have of them."

It seems that some automobile manufacturers may have a similar opinion. "The automobile industry is deliberately trying to sabotage electric and natural gas vehicles," (Savage 7). However, these two industries are not in the majority as low cost alternatives are constantly being developed by engineers in the United States and Europe. These industry giants also may soon have no choice but to explore and diversify into more alternative fuel options as they have done in Brazil, (Grammer, 10). Emissions standards are growing stricter throughout the States, especially in California where a percentage of cars sold must be zero emission vehicles.
