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.

Did you know that skis and snowboards benefit from Infrared heat?

Not only should skis and snowboards look appealing, they also need to be built to withstand the rigors of snow and ice. Almost all popular skis and snowboards contain composite materials, which are manufactured by Isosport in Austria.

For the modern, high-quality composite fabrics rovings and fabrics made of glass and carbon fiber are impregnated with high-quality epoxy resins.

New Material to Push the Boundaries of Silicon-Based Electronics

The electronics market is growing constantly and so is the demand for increasingly compact and efficient power electronic systems. The predominant electronic components based on silicon will in foreseeable future no longer be able to meet the increasing industrial requirements.This is why scientists from the university of Freiburg, the Sustainability Center Freiburg and the Fraunhofer-Gesellschaft have joined forces in order to explore a new material structure that may be better suited for future power electronics.

The recently launched project »Research of Functional Semiconductor Structures for Energy Efficient Power Electronics« (in short »Power Electronics 2020+«)...

Tandem Solar Cells – Record Efficiency for Silicon-based Multi-junction Solar Cell

Silicon solar cells dominate the photovoltaic market today but the technology approaches the theoretical maximum efficiency that can be achieved with silicon as the only absorber material. Tandem solar cells, on the other hand, combine several absorber materials, enabling a better energetic use of the solar irradiance spectrum. Due to their higher efficiency potential, tandem solar cells have a promising future. After intensive research, scientists at Fraunhofer ISE in cooperation with partners have achieved a new efficiency record of 22.3 percent for a multi-junction solar cell made of silicon and III-V semiconductor materials.

The outstanding achievement is that the III-V layers were directly grown on the silicon.

Better Protection for Power Converters During Turbine Operation

Power converters are among the most frequently failing components of wind turbines and are thus associated with high costs and long downtimes. A better understanding of the causes of their failure is vital for developing effective protective measures and thus improve the profitability of turbine operation. A project consortium composed of operators and manufacturers of turbines, semiconductors, and converters is working closely together with research partners in the project ReCoWind, funded by the German Federal Ministry for Economics Affairs and Energy. Field data from various sites and turbine types are being analyzed, damage models derived, and experimental tests performed on components.

Economic losses of around € 200 million per year arise in Germany alone due to repair costs and revenue losses resulting from failed power converters in wind...
