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.

Fraunhofer IWKS Starts Project “BReCycle” on Efficient Recycling of Fuel Cells

There is currently no industrial recycling process tailored to fuel cells. As part of the "BReCycle" project, a research consortium led by Fraunhofer IWKS is now developing a recycling management concept specifically for PEM fuel cells.

More sustainable, efficient and environmentally friendly energy conversion technolo-gies such as fuel cells will play an increasingly important role in the...

Synthetic gas instead of fossil energy

There is one major challenge in converting our energy system to purely renewable energy sources: winter – or rather the supply gap at this time. The conversion of surplus summer electricity into synthetic gas offers a way of ensuring that renewable energy could be available in sufficient quantities during the winter months. It would also allow to operate long-distance trucks. The Canton of Zurich has great interest in replacing fossil fuels with renewable energies and is, therefore, providing financial support for the Empa's "Power-to-gas" project.

The call to abandon fossil fuels altogether is becoming ever louder, not just in Switzerland but also in the EU and numerous other countries. While a number of...

Lade-PV Project Begins: Vehicle-integrated PV for Electrical Commercial Vehicles

Heavy-load vehicle traffic is responsible for 6 percent of the CO2 emissions in the European Union. Solar electricity generated directly on the vehicle can improve this balance by 5 to 7 percent. In the “Lade-PV” project under the direction of the Fraunhofer Institute for Solar Energy Systems ISE, four industrial companies and two Fraunhofer institutes want to demonstrate the market feasibility of PV applications in the heavy-load transport. The aim is to develop an overall concept that makes the widespread use of integrated PV modules on electrical and other commercial vehicles (over 3.5 tons commercial load) possible.

In the coming three years, not only singular components, such as PV modules and power electronic units, but also manufacturing and production concepts will be...

When ions rattle their cage

Electrolytes play a key role in many areas: They are crucial for the storage of energy in our body as well as in batteries. In order to release energy, ions - charged atoms - must move in a liquid such as water. Until now the precise mechanism by which they move through the atoms and molecules of the electrolyte has, however, remained largely unknown. Scientists at the Max Planck Institute for Polymer Research have now shown that the electrical resistance of an electrolyte, which is determined by the motion of ions, can be traced back to microscopic vibrations of these dissolved ions.

In chemistry, common table salt is also known as sodium chloride. If this salt is dissolved in water, sodium and chloride atoms dissolve as positively or...

Harnessing the rain for hydrovoltaics

Drops of water falling on or sliding over surfaces may leave behind traces of electrical charge, causing the drops to charge themselves. Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz have now begun a detailed investigation into this phenomenon that accompanies us in every-day life. They developed a method to quantify the charge generation and additionally created a theoretical model to aid understanding. According to the scientists, the observed effect could be a source of generated power and an important building block for understanding frictional electricity.

Water drops sliding over non-conducting surfaces can be found everywhere in our lives: From the dripping of a coffee machine, to a rinse in the shower, to an...

New explanation for sudden heat collapses in plasmas can help create fusion energy

Scientists seeking to bring the fusion that powers the sun and stars to Earth must deal with sawtooth instabilities -- up-and-down swings in the central pressure and temperature of the plasma that fuels fusion reactions, similar to the serrated blades of a saw. If these swings are large enough, they can lead to the sudden collapse of the entire discharge of the plasma. Such swings were first observed in 1974 and have so far eluded a widely accepted theory that explains experimental observations.
