Fuel cell vehicles are being developed because they promise to meet the requirements expected of automobiles in a market increasingly constrained by environmental and resource limitations. Air pollution and oil dependence have been persistent challenges for vehicles powered by petroleum fuels (gasoline and diesel). Global warming presents a new challenge in the need to limit carbon dioxide (CO) emissions from fossil fuel combustion. (more…)

With popularity of clean energy, the reduction of carbon and the movement toward earth friendliness, it seems that investment in alternative energy fund would be virtually no risk. But like any new industry, there is no guarantee that all sectors of the market will be successful. Since the technology bubble, which began in the early and mid 90s the market for alternative energy will soon separate winners from losers. If you are lucky or wise enough to choose an achiever, you soon will be getting great gain in your investment. On the other hand, losses are for those who have taken up the approximation that was not well received by the substantial market. (more…)

Some of alternative fuel sources are by no means new. For centuries people have harnessed the power of running water for a variety of needs, particularly for agriculture or farming. Water wheels were constructed in the Middle East, Greece, and China thousands of years ago, and they were common fixtures on the farms of Europe by the Middle Ages. In the early 21st century hydroelectric dam, which generate electricity from the power of rivers, provide about 9 % of the electricity in the United States. Worldwide, there are about 40,000 such dams. (more…)

Coal is an important energy source and energy consumption in United States as well as worldwide. It will remain so for many years particularly in many developing countries. Fossil fuels stay as the main energy sources to the U.S. economy, but we can not ignore the importance of coal for decades. Coal production provides the price stability and will continue to be an significant source for electricity generation. Coal utilization is the major source of hydrogen in the coming hydrogen-based energy economy and it will be a crucial source of gas to liquid process of fuels energy.
Coal utilization and the importance of coal as source of energy industry perspective will change over time. (more…)

Natural gas is found mainly in underground reservoirs and in coal beds. Natural gas is a fossil fuel that consist primarily of methane and some smaller amounts of hydrocarbons subtracts like ethane, propane and butane. There might be some inert gas like nitrogen, helium, and carbon dioxide involved and dissimilated into natural gas. The actual mixture composition is varies depending upon the region where that natural gas is found. (more…)
