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.

Biologically inspired skin improves robots' sensory abilities (Video)

Sensitive synthetic skin enables robots to sense their own bodies and surroundings - a crucial capability if they are to be in close contact with people. Inspired by human skin, a team at the Technical University of Munich (TUM) has developed a system combining artificial skin with control algorithms and used it to create the first autonomous humanoid robot with full-body artificial skin.

The artificial skin developed by Prof. Gordon Cheng and his team consists of hexagonal cells about the size of a two-euro coin (i.e. about one inch in...

Smaller than a coin

Nowadays, a mobile phone can do almost anything: take photos or video, send messages, determine its present location, and of course transmit telephone conversations. With these versatile devices, it might even be possible to ascertain a beer's alcohol content or how ripe a piece of fruit is.

At first glance, the idea of using mobile phones for chemical analyses seems a daring one. After all, the infrared spectrometers used for such analyses today...

Wind power from the Sky

To harvest wind energy, you don't necessarily need rotors on steel masts – light kites on thin ropes can do the same. The Empa spin-off TwingTec has been researching this technology for some time now. Last autumn, it was possible for the first time to start, generate electrical energy while flying and then land again, all in the specified level of automation. Empa specialists now will participate at the 8th Airborne Wind Energy Conference in Glasgow. The latest Twingtec prototype is about to get airborne in the next month.

Anyone who has ever steered a child's kite knows the feeling: the wind grips the kite and pulls the string. The rope is quickly tensioned, the pulley rotates...

Im Focus: Controlling superconducting regions within an exotic metal

Superconductivity has fascinated scientists for many years since it offers the potential to revolutionize current technologies. Materials only become superconductors - meaning that electrons can travel in them with no resistance - at very low temperatures. These days, this unique zero resistance superconductivity is commonly found in a number of technologies, such as magnetic resonance imaging (MRI).

Future technologies, however, will harness the total synchrony of electronic behavior in superconductors - a property called the phase. There is currently a...
