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.

Project pairs coal with fuel cells to create cleaner, more efficient power

Ohio University engineers are leading one of the first comprehensive efforts to examine how fuel cell technology could pave the way for cleaner coal-fired power plants. Supported by a $4 million U.S. Department of Energy grant secured by the Ohio Congressional delegation, the project aims to find ways to use coal – the environmentally dirtiest but most abundant fossil fuel in the world -- to harness high-efficiency fuel cells. Most government-sponsored energy research is focused on using nat 30.05.2003 | nachricht Read more

A more efficient, lighter device that generates up to three times more electricity from waves

The world’s oceans hold the key to our future electricity needs. And their potential for producing power has yet to be fully exploited in terms of sustainable energy. The EUREKA WWEC project team hopes to bring exploitation of this renewable energy source a big step forward. “We’ve developed a device that generates energy from the sea as easily as a wind turbine would do on land,” explains William Dick, managing director of the Irish company Wavebob that led the project. “There’s an awful lo 20.05.2003 | nachricht Read more

New sensor bares faults in smallest possible, most advanced circuits

A new scanning microscope developed at Brown University can uncover defects in the smallest and most complex integrated circuits at a resolution 1,000 times greater than current technology. The scanner removes a barrier to further shrinking of integrated circuits: As circuits get smaller, non-visual defects become harder to find. “This microscope will allow manufacturers to find defects in each embedded wire in ever-tinier circuits,” said Brown University professor Gang Xiao. He developed th 12.05.2003 | nachricht Read more

Infrared thermography

Thermography provides the easy checking of points throughout an electric system where faults may arise, and with sufficient warning in order to correct the fault before things get worse. Infrared thermography provides the visualisation of temperature differences arising at the surfaces of objects. The tool used is a portable and autonomous camera (similar to a home video camera) which is equipped with a detector which permits the measurement and visualisation of thermal images.

Photonic crystals to improve microwave circuits

The principal aim of this PhD paper was the application of the new concepts and ideas of Photonic Crystals and Photonic Bandgap (PBG) to microwave and millimetric circuits and, more concretely, to microstrip circuits which is the most common technology in current use in flat microwave circuits. Thus, for this thesis, the techniques for optimising the functioning of PBG structures in microstrip technology were studied and the various practical applications of these devices were analysed.

Im Focus: Small particles, big effects: How graphene nanoparticles improve the resolution of microscopes

Conventional light microscopes cannot distinguish structures when they are separated by a distance smaller than, roughly, the wavelength of light. Superresolution microscopy, developed since the 1980s, lifts this limitation, using fluorescent moieties. Scientists at the Max Planck Institute for Polymer Research have now discovered that graphene nano-molecules can be used to improve this microscopy technique. These graphene nano-molecules offer a number of substantial advantages over the materials previously used, making superresolution microscopy even more versatile.

Microscopy is an important investigation method, in physics, biology, medicine, and many other sciences. However, it has one disadvantage: its resolution is...
