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.

Can you cool with waste heat? Sure. A Swiss research project involving Empa, which ended in November, demonstrated this in an impressive way. Now a large-scale EU project is starting: industrial cooling – thanks to the Spanish sun.
Every now and so often heating something up is unavoidable. Potato soup or risotto, tomato sauce or chocolate pudding – all unfeasible without heat. A small...25.06.2019 | Read more
At the end of May, the final meeting of the "Horizon 2020" project "GasOn" with the EU Commission took place in Brussels. The aim of this EU project was the further development of gas engines for cars and vans. Around 20 partners participated, including ETH Zurich and Empa as well as four European automobile manufacturers and well-known suppliers. Gas-powered vehicles generally emit less pollutants than petrol or diesel cars. They are likely to gain importance in the future due to their possibility of being powered by renewable energy.
In addition to electric and hydrogen powertrains, gas engines also play an important role in the Swiss Competence Centre for Energy Research in the Field of...21.06.2019 | Read more
The whole world is inevitably moving towards a more sustainable lifestyle. Sustainability of the environment requires changes in the current way of life and introduction of new, more sustainable solutions in our everyday consumption.

In the new infrastructure project NextGenBat, six institutes are paving the way for the research and development of future battery systems. RWTH Aachen University, Forschungszentrum Jülich and the Fraunhofer Institute for Laser Technology ILT are involved in the project, which will particularly strengthen the federal state North Rhine-Westphalia as a high-tech location for energy storage development. NextGenBat was launched on September 5, 2018 within the “Research Infrastructures“ funding initiative of North Rhine-Westphalia as part of the operational NRW-EFRE program.
It is already expected that the solid fuel battery will have a significant impact on electromobility over the next ten years. To successfully industrialize...12.06.2019 | Read more

Fraunhofer IZM is joining the EUROPRACTICE IC Service platform. Together, the partners are making fan-out wafer level packaging (FOWLP) for electronic devices available and affordable even in small batches – and thus of interest to research institutes, universities, and SMEs. Costs can be significantly reduced by up to ten customers implementing individual fan-out wafer level packaging for their ICs or other components on a multi-project wafer. The target group includes any organization that does not produce in large quantities, but requires prototypes.
Research always means trying things out and daring to do new things. Research institutes, universities, and SMEs do not produce in large batches, but rather...06.06.2019 | Read more

NCCR MARVEL researchers have developed a novel microscopic theory that is able to describe heat transport in very general ways, and applies equally well to ordered or disordered materials such as crystals or glasses and to anything in between. This is not only a significant first--no transport equation has been able so far to account simultaneously for these two regimes--it also shows, surprisingly, that heat can tunnel, quantum-mechanically, rather than diffuse away, like an atomic vibration.
The new equation will also allow the accurate prediction of the performance of thermoelectric materials for the first time. With ultralow, glass-like, thermal...28.05.2019 | Read more

For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.
