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.

Mobile robot cleaner takes production hygiene to a higher level

Production lines and hygiene zones have to be spotlessly clean. And absolute cleanliness is critical wherever food is processed and medical instruments are handled. Now Fraunhofer researchers have come up with a mobile cleaning device that sanitizes equipment and production spaces to standards in a reproducible way. Equipped with self-learning and autonomous motility systems, this robot automatically detects the degree of fouling and selects the appropriate cleaning procedure.

There is no room for compromises when it comes to hygiene in industrial food production. Manufacturing equipment and rooms need regular cleaning.

Impact assessment of F-gas free medium voltage switchgear

Sulphur hexafluoride (SF6) plays an important role as an insulating gas in electrical switchgear at various voltage levels when interrupting and diverting current flows. But it is one of the most effective greenhouse gases with a very long lifetime and, although the concentration of SF6 in the atmosphere is currently still very low, it accumulates steadily over the years. The Fraunhofer IEE and the Grenoble Ecole de Management (GEM) finalized a research study investigating the development of MV switchgear installations under different boundaries showing the impact on SF6 emissions, and analyzing the market acceptance of SF6-free alternatives, as well as barriers and drivers to adoption.

The Fraunhofer Institute for Energy Economics and Energy System Technology
IEE in Kassel designed a model for estimating the installed base and analyzing the...

Batteries for electric cars: Fact check and answers to the most important questions about electric mobility

How well do electric cars perform environmentally? How will their range, economic efficiency and charging infrastructure develop in the long term? Will electric mobility mean job losses? These and many other questions to do with the battery value chain are addressed by the Fraunhofer ISI in a Policy Brief, which was presented at the Battery Forum Germany in Berlin. Main message: there is nothing to stop the widespread market diffusion of electric cars between 2020 and 2030+, although numerous challenges still have to be addressed.

The technological maturity of batteries for electric cars and whether these make economic and environmental sense is still being questioned by critics today,...

What grade do our electronic products get? Life cycle assessment in the electronics industry

Although life cycle assessments do not save the environment, it can make industry think, as the example of life cycle assessments for electronics shows. Every electronic product, useful as it may be, comes with a heavy ecological backpack: From the extraction of raw materials used and design decisions to the use and disposal of an electronic product, every step in the manufacturing process leaves its mark on the environment. Researchers at Fraunhofer IZM analyse the entire life cycle of electronic products and product groups on the basis of standardised benchmarks and ISO norms and develop optimisation proposals.

Ever more manufacturers and users are interested in the environmental impact that products have. The focus is not only on what a product can do but also on the...
