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.

NextGenBat: Basic research for mobile energy storage systems

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...

Cost-effective and individualized advanced electronic packaging in small batches now available

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...

Researchers introduce novel heat transport theory in quest for efficient thermoelectrics

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...

A simple, yet versatile, new design for chaotic oscillating circuitry inspired by prime numbers

Researchers at Tokyo Institute of Technology have found a simple, yet highly versatile, way to generate "chaotic signals" with various features. The technique consists of interconnecting three "ring oscillators," effectively making them compete against each other, while controlling their respective strengths and their linkages. The resulting device is rather small and efficient, thus suitable for emerging applications such as realizing wireless networks of sensors.

Our ability to recreate the signals found in natural systems, such as those in brains, swarms, and the weather, is useful for our understanding of the...

Machine learning speeds modeling of experiments aimed at capturing fusion energy on Earth

Machine learning (ML), a form of artificial intelligence that recognizes faces, understands language and navigates self-driving cars, can help bring to Earth the clean fusion energy that lights the sun and stars. Researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) are using ML to create a model for rapid control of plasma -- the state of matter composed of free electrons and atomic nuclei, or ions -- that fuels fusion reactions.

The sun and most stars are giant balls of plasma that undergo constant fusion reactions. Here on Earth, scientists must heat and control the plasma to cause...

Im Focus: MPSD team discovers light-induced ferroelectricity in strontium titanate

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.

Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
