Energy policies relating to alternative energy

Current energy policies are still based heavily on natural resources. Meanwhile, the trend is increasingly toward alternative resources, such as wind power.

It's only a matter of time before natural resources, such as petroleum, are depleted. Petroleum, a fossil-based energy source deposited across millions of years, is used to produce fuel or electricity. Taking stock of the fact that 260 billion barrels (one barrel = 159 liters) of oil were extracted over the last 11 years, it's evident that the world's petroleum resources will be depleted one day. New developments in solar or wind power are aimed at providing alternative energy sources that will enable us to maintain our current standard of living. Petroleum is also required by the chemical industry to manufacture special plastics.

The advantages and disadvantages of alternative energy sources

When discussing the subject of petroleum and alternative energy, one must bear the advantages and disadvantages in mind. Our resources are running short . Because we cannot count on petroleum for the future, there will come a time when everyone will rely on the efficiency of wind power and other alternative energy sources . Unlike petroleum, wind power can be managed to ensure that it constantly renews itself. Wind power meanwhile makes it possible to have enough resources to supply entire cities. Petroleum has the additional disadvantage of harming the environment through CO2 emissions. This has resulted in increasing demand for resources such as wind power. Wind power can be classified into different categories. A class 4 wind turbine can meanwhile provide resources in a much more efficient manner than petroleum resources for instance. In addition, unlike petroleum, resources such as wind power offer a decentralized energy supply. This means that in contrast to petroleum, the utilization of wind power does not require a large power plant. Instead, it makes "transporting" the energy easier and faster. Decentralized wind power entails a massive infrastructure change. Resources such as wind power certainly bring disadvantages when it comes to the environment, although they pale in comparison to the disasters that can result from petroleum. The utilization of our resources determines how we continue to maintain our standard of living. This makes it important to continue public discourse on the issues of wind power and petroleum.

Resource shortage

It's only a matter of time before there is no petroleum left. For this reason, from a resource standpoint we should already be moving toward heavy reliance on wind power instead of petroleum. After all, from a pure scientific point of view, new petroleum resources won't be available for millions of years. Unlike petroleum, wind power is a resource that will never run dry. In Germany alone, wind power is serving as a popular alternative resource to petroleum. The demand for wind power will increase in line with the consumption of petroleum. For this reason, it is imperative that we gradually move away from petroleum and make more use of wind power or other alternative energy resources. The environmental pollution caused by petroleum is reason enough for an environmentally-conscious society to use solar or wind power. In contrast to petroleum, wind power is significantly better for the environment and offers a unique resource balance.

Tiny heaters may pave way for easier tissue engineering, medical sensors

Tiny microheaters that can prompt chemical changes in surrounding material may provide the means to more easily grow replacement tissue for injured patients and form the basis for medical sensors that could quickly detect pathogens, according to researchers at the University of Washington who are the first to demonstrate the process. The key to the technique, according to Associate Professor Karl Böhringer in the UW’s Department of Electrical Engineering, lies in temperature-driven cha 08.01.2004 | nachricht Read more

Scientists find new way to store hydrogen fuel

University of Chicago scientists have proposed a new method for storing hydrogen fuel in this week’s online edition of the Proceedings of the National Academy of Sciences. The lack of practical storage methods has hindered the more widespread use of hydrogen fuels, which are both renewable and environmentally clean. The most popular storage methods-liquid hydrogen and compressed hydrogen-require that the fuel be kept at extremely low temperatures or high pressures.

New light-emitting transistor could revolutionize electronics industry

Put the inventor of the light-emitting diode and the maker of the world’s fastest transistor together in a research laboratory and what kinds of bright ideas might surface? One answer is a light-emitting transistor that could revolutionize the electronics industry. Professors Nick Holonyak Jr. and Milton Feng at the University of Illinois at Urbana-Champaign have uncovered a light-emitting transistor that could make the transistor the fundamental element in optoelectronics as well as in elec 06.01.2004 | nachricht Read more

Tiny nanotube antennas may yield better signals in cell phones, televisions

In the future, your cell phone calls and television pictures could become a lot clearer thanks to tiny antennas thousands of times smaller than the width of a human hair. At least that’s the speculation of a University of Southern California researcher who has been investigating nanotube transistors. The USC scientist, Bart Kosko, Ph.D., a professor in the school’s Electrical Engineering Department, led a study that has demonstrated for the first time that minuscule antennas, in t 30.12.2003 | nachricht Read more

Wind energy not limited by technical barriers

Dutch research has demonstrated that there are no technical barriers to wind energy generating a significant part of the electricity supply. With the appropriate technical measures, possible problems in the electricity grid can be taken care of properly. Researcher Han Slootweg developed simulation models, which demonstrate how wind energy affects the behaviour of electricity grids in concrete situations. These simulation models can also be used to establish the precise nature and size of a 22.12.2003 | nachricht Read more

Does wind power have a chance? Four analyses from Lund Institute of Technology

Wind power is the most rapidly growing form of energy in the world today. European wind power accounts for the greatest share, with Denmark, Germany, and Spain as leading countries. In Denmark, for example, wind power provides roughly 12 percent of production of electricity. In Sweden, too, wind power has increased, although to a more limited extent. Between 1996 and 2003 the number of plants doubled from 300 to 631, while annual production trebled from 0.15 to about 0.5 TWh. However, wind accounts f 18.12.2003 | nachricht Read more

To see the message, just add noise

USC nanotube device uses ’Stochastic Resonance’ to enhance subthreshold signals Paradoxical as it seems, a team of University of Southern California researchers has built a signal detector that only works when noise is added.

Smaller, lighter power adaptors take the weight off laptops

As notebook computers become thinner and lighter, the ever-present bulky power adapters used for line current approach the weight of the laptops, but smaller and lighter adapters may be on the way, thanks to piezoelectric technology, according to a Penn State electrical engineer. "Electromagnetic transformers are shrinking slightly, but there are theoretical limitations in reducing the general size," says Dr. Kenji Uchino, professor of electrical engineering.

In an article published in the December 12th issue of Science, researchers at The Institute for Genomic Research (TIGR) and the University of Massachusetts, Amherst, report that Geobacter sulfurreducens possesses extraordinary capabilities to transport electrons and "reduce" metal ions as part of its energy-generating metabolism. 12.12.2003 | nachricht Read more

Gas Hydrates – Will they be considered in the future global energy mix?

For the first time, an international research program involving the Department of the Interior’s U.S. Geological Survey has proven that it is technically feasible to produce gas from gas hydrates. Gas hydrates are a naturally occurring "ice-like" combination of natural gas and water that have the potential to be a significant new source of energy from the world’s oceans and polar regions.
