Strategic Issues and Problems:
The global shortage of oil and its effect on the environment has brought substantial public attention to the renewable and alternative power sources. The technology of using alternative fuel for cars besides gasoline has been advancing rapidly over the years. In light of this, car manufacturers have introduced hybrid cars which combine two or more sources of energy as fuel. However, many argue that most of these sources, such as biodiesel, ethanol, methanol, and natural gas, have either consume other types of oil or combine with traditional gasoline or diesel. Therefore, these do not solve the root cause of oil consumption. It may even create a shortage in another resource and other negative economic impacts. For instance, ethanol is primarily made from corn and can be used by blending it with gasoline. If ethanol is widely adopted as an alternative fuel source, it raises the price for food supply while the oil problem still remains unsolved. Currently, hydrogen is one of the most abundant elements on earth, and can also be produced domestically from other energy sources, including biomass, wind, water and other waste materials. It has zero pollution, high fuel efficiency and renewability, which make hydrogen an ideal alternative energy source for consumers and automakers in the long term.
Evaluation and Analysis:
Many scientists find that hydrogen can significantly reduce global warming and other types of pollutions. Hydrogen fuel cells can be easily produced and operated by separating water into oxygen and hydrogen under electrolysis or extracting from food and animal wastes. It produces no emission other than pure water and eliminates human and animal wastes at the same time. Pure hydrogen fueled vehicles have the same concept as hybrid cars. It charges the fuel cell battery by converting hydrogen and oxygen into electricity and powers the engines. According to the...
