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.

Sandia polymer electrolyte membrane brings goal of a high temperature PEM fuel cell closer

A new type of polymer electrolyte membrane (PEM) is being developed by researchers at the Department of Energy’s Sandia National Laboratories to help bring the goal of a micro fuel cell closer to realization using diverse fuels like glucose, methanol, and hydrogen. This Sandia Polymer Electrolyte Alternative (SPEA) could help fulfill the need for new, uninterrupted autonomous power sources for sensors, communications, microelectronics, healthcare applications, and transportation. 06.05.2004 | nachricht Read more

New research will cut cost of solar energy by half

The largest single research project into solar power ever funded by the UK research councils was launched this month and could help make the energy source much more widely used in Britain. The University of Bath is among six universities and seven companies in the UK that began the £4.5 million project this month (April) to halve the cost of converting the sun’s rays to electricity using solar cells. The four-year research project could make solar power a viable alternative to 29.04.2004 | nachricht Read more

High-speed nanotube transistors could lead to better cell phones, faster computers

Scientists have demonstrated, for the first time, that transistors made from single-walled carbon nanotubes can operate at extremely fast microwave frequencies, opening up the potential for better cell phones and much faster computers, perhaps as much as 1,000 times faster. The findings, reported in the April issue of Nano Letters, a peer-reviewed journal of the American Chemical Society, the world’s largest scientific society, add to mounting enthusiasm about nanotechnology’s rev 28.04.2004 | nachricht Read more

PNNL on fast track for hydrogen fuel reformer

Researchers at the Department of Energy’s Pacific Northwest National Laboratory are developing a system to rapidly produce hydrogen from gasoline in your car. "This brings fuel cell-powered cars one step closer to the mass market," said Larry Pederson, project leader at PNNL. Researchers will present their developments at the American Institute for Chemical Engineers spring meeting in New Orleans, on April 27th, 2004.

Portable ’rainbow’ source improves color calibrations

If you need bright blue light at a very specific wavelength, the National Institute of Standards and Technology (NIST) can make it---and fast. In the world of color, this is no small accomplishment. NIST’s traditional light sources, such as incandescent lamps, are thermal. A blue thermal source would need to function at such a high temperature that components would melt. Lack of blue light sources introduces uncertainty when calibrating instruments that measure the color of things like 26.04.2004 | nachricht Read more

ORNL researchers focus on the CO2 big picture

Spring’s lush green lawns and hot pink shoes contribute at least in a small way to the world’s total carbon picture, say researchers at the Department of Energy’s Oak Ridge National Laboratory. Indeed, the latest fashions on Fifth Avenue and fertilizers that help homeowners achieve that "barefoot" lawn have their associated carbon dioxide costs, and ORNL’s Gregg Marland and Tristram West keep up with them. Their task is to track the total carbon produced worldwide and es 23.04.2004 | nachricht Read more
