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.
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.
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.

A Binghamton University engineering researcher designed a biological solar cell that’s a million times more effective than current technology. Preliminary data on Seokheun “Sean” Choi’s next advancement is a thousand times better than that. His cell also works in the dark, and is self-sustaining.
The new designs don’t make biological solar cells practical, yet. But they do take them out of the realm of “absurd” and place them squarely in the realm of...11.02.2015 | Read more

A recently released study led by U.S. Forest Service scientists and published by the Forest Service's Southern Research Station (SRS) finds that policies in the European Union (EU) and elsewhere requiring the use of renewable and low greenhouse gas-emitting energy are driving demand for wood pellets used to generate bioenergy. This demand could provide new markets for U.S. timber exports, increase wood prices, and lead to increases in forestland area.

Traditional sterilisation methods are no longer effective against all pathogens. By means of plasma, on the other hand, exceptionally stubborn bacteria stems can be killed off, as demonstrated by Junior Professor Dr Katharina Stapelmann from the Institute for Electrical Engineering and Plasma Technology. She has developed a steriliser that is specifically suited for ridding medical instruments of germs efficiently, yet without damaging the material. As reported in the RUB’s science magazine “RUBIN”, the process is also interesting for the aerospace industry.

In various industries such as automotive industry, aircraft or steel construction failures in the final product can quickly lead to malfunction and, as a result, can massively compromise the operational reliability. Thus, nondestructive testing methods will play a key role in the quality assurance because they allow to inspect components and parts without destroying them.
From 10 to 12 March 2015, at the JEC Europe in Paris, engineers of Fraunhofer IZFP in Saarbrücken will introduce a novel procedure which enables noncontact and...
