A fuel cell is an electrochemical device that combines hydrogen with oxygen to generate electricity, heat and water to produce. In many ways, the fuel cell is similar to an electrochemical cell. Instead of a regular charge, a continuous supply of oxygen and hydrogen is supplied from outside. Oxygen is produced in the control of air and hydrogen as a fuel made from a pressure instrumentation container. Alternatively, methanol, propane, butane, natural gas supply and diesel are used.

Natural gas and oil are common source energy used to give electricity. How efficient is coal if we compare to these other source of energy? With respect to security of supply, coal has a clear advantage. The United States has about 300 million recoverable tons of coal. This amount is sufficiency to last 300 years if we are consuming coal in the same ratio that we used today. In addition, carbon is a versatile and cheap source of fuel. Coal can be used as a solid fuel or converted into a gas to replace expensive imported fuels. (more…)

The U.S. Department of Energy has determined that about 80% of residential energy use is consumed in single-family homes, while 15% is consumed in multifamily dwellings such as apartments, and 5% is consumed in mobile homes.
More than half of the energy used for heating in building and home for single-family homes is natural gas, about one-fourth is electricity, (more…)

Geopolitical risk refers almost always to primary energy carriers (oil, gas, coal, uranium or renewable energy) since their location depends on the vagaries of geology and climate. Production and energy consumption are thus often physically far apart and take place in countries and regions with different histories, cultures and values. Apart from oil & gas exploration and production, all other steps of the energy chain such as refinement or enrichment, energy conversion and distribution can be moved physically closer to the final customer or are, like consumption, directly under the latter’s control.

Most major oil and gas firms engage in both upstream (i.e., hydrocarbon exploration and production) and downstream (i.e., hydrocarbon refining and marketing) businesses as well as related activities such as chemicals, and their R&D activities serve the needs of these businesses. During the past decade or so, the R&D spending of oil and gas firms has generally declined. According to a DOE survey, R&D spending by major energy producers within the United States declined from $3.05 billion in 1994 to $1.33 billion in 2000. Although not true of all producers internationally, the broad global trend over the past decade or so seems to be along similar lines. (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…)

The increase in the prices of major fuels, like gasoline and diesel fuel products is a major global problems recently. Those prices are increase associated with the global economic crisis. Now, it is the ideal time to move all the focus and effort to alternative fuels for vehicles. There are different types of alternative energy sources for fuel to choose from. But the hard fact is that the areas of alternative fuels have not passed many real qualitative and quantitative surveys and breakthrough research. (more…)
