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.

Heat pumps play a decisive role in the energy transition: Sustainably generated electricity provides heat in winter and a good climate in summer. Nowadays, heat pumps work almost exclusively on the basis of compressor technology. Compressors require harmful refrigerants, the use of which will be restricted even more by law in the future. In the Fraunhofer ElKaWe lighthouse project, six Fraunhofer Institutes are developing highly efficient electrocaloric heat pumps, which do without harmful refrigerants.
Heat pumps based on compressors are used for heating and cooling. However, the refrigerants used in the systems can be harmful to climate, health and the...09.12.2019 | Read more

Innovative development of antennas for improved safety in sea rescue services: Funded by the German Federal Ministry of Education and Research (BMBF), the Fraunhofer Institute for High-Frequency Physics and Radar Technology FHR has joined forces with the Institute for Microwaves and Plasma Technology of the FH Aachen and Raytheon Anschütz GmbH to develop a harmonic radar system that can safely locate persons in the water. At the final presentation of the consortium partners, which also includes the company Kadematic Seenotrettungsgeräte GmbH as an associated partner, the experimental system was successfully tested in Eckernförde.

Scientists of the Dresden Integrated Center for Applied Physics and Photonic Materials (IAPP) and the Center for Advancing Electronics Dresden (cfaed) at TU Dresden have developed a novel storage technology based on the combination of an organic light-emitting diode (OLED) and an insulator. This device allows reading the stored information optically as well as electrically. Moreover, the information can be added in portions - thus several storage states can be mapped in one device. The results have now been published in the renowned journal "Advanced Functional Materials".
Another novelty was related to the measurements in the test series: They were carried out exclusively using the innovative "SweepMe!” measuring software, which...25.11.2019 | Read more
The semiconductor industry has been developed for more than 40 years following the Moore's Law. With the size of transistors being shrinking down to tenth of nanometer scale, the quantum effects start to dominate and cause problems such as operation stability and heat generations [Fig. 1a] . An alternative route is to develop new functional materials and their architectures. Complex oxide is one of the most promising candidates. Recently, scientists have shown novel phenomena of complex oxide at nanometer length scale and its potential for applications.
