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.

Factory networks energy, buildings and production

In the “ETA Factory” demonstration project, the Technische Universität Darmstadt is researching concepts for multi-networked, industrial production facilities. In the concept, the scientists are integrating the energy flows, building envelope and industrial process chain across technologies and disciplines. The new BINE-Projektinfo brochure entitled “Energy efficient model factory” (03/2018) presents the ETA Factory, which serves as a research object, demonstration facility and place of learning. By shifting the system boundaries between the machines and building, the researchers expect economically feasible energy savings of up to 40%.

Darmstadt model project is testing the production of the future

Manipulating single atoms with an electron beam

All matter is composed of atoms, which are too small to see without powerful modern instruments including electron microscopes. The same electrons that form images of atomic structures can also be used to move atoms in materials. This technique of single-atom manipulation, pioneered by University of Vienna researchers, is now able to achieve nearly perfect control over the movement of individual silicon impurity atoms within the lattice of graphene, the two-dimensional sheet of carbon. The latest results are reported in the scientific journal "Nano Letters".

As an epoch-making achievement in nanotechnology, the scanning tunneling microscope has since the late 1980s been able to move atoms over surfaces, and has...

Photovoltaic Technology Evaluation Center PV-TEC Reopens: Innovation Platform for the PV Industry

Opened as a research factory for solar cells twelve years ago, the Photovoltaic Technology Evaluation Center PV-TEC at Fraunhofer ISE is an important player in the piloting of crystalline silicon solar cells. The unique service center for the entire PV value chain helps to close the gap between research and industry, making it a pivotal driver of innovation transfer. After a fire badly damaged the facility last year, the PV-TEC technology platform was officially reopened on July 9, 2018, complete with brand new equipment.

In February 2017, a fire rendered the equipment at Fraunhofer ISE’s Photovoltaic Technology Evaluation Center PV-TEC in the Solar Info Center in Freiburg...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
