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.

Silicon Carbide Transistors Improve Efficiency in Home Storage Systems

To meet the evolving needs of climate change and the German energy transition, as well as combat the rising energy costs for end consumers, more and more households are adding home storage systems to their PV systems. A major challenge of PV home storage is that the batteries are charged within a few hours in intense sunlight and then discharged at very low power, or partial load, over a long time period during the night. Because of this, battery inverters in home storage systems should have high conversion efficiency over the largest power range possible.

In the HyBaG project, which started in 2017, the Fraunhofer Institute for Solar Energy Systems ISE in collaboration with Kaco New Energy and STS -...

Taking stock: New FVV meta study of life-cycle analyses on alternative powertrain technologies

Life cycle analyses (LCA) provide evidence of how climate-friendly new powertrain technologies are. A new meta-analysis by the Research Association for Internal Combustion Engines (FVV) analyses existing life-cycle studies from the last 15 years. A supplementary paper derives central requirements for drafting future climate protection regulations and guidelines. The study results show that in a global energy and carbon system, various technology options are available from a climate perspective. There is not one single solution for CO2 neutrality in the mobility sector. The key to sustainable mobility lies in fair technology competition and the defossilisation of energy production.

Mobile measuring instruments: Caught in flight

Humans are exposed to numerous harmful environmental influences, and it is an international concern to quantify these emissions as accurately as possible in order to be able to take measures to contain them. Empa is also part of these efforts and has, among other things, developed a drone equipped with state-of-the-art measuring instruments which can detect methane leaks. It is also assisting the European Space Agency (ESA) in the development of new satellites capable of detecting CO2 sources from space.

Methane (CH4) is one of the main causes of global warming, but the contribution of the individual methane sources is still not exactly known. Such...
