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.

Did you know that specialty light sources are used to ensure the quality of baby food?

For almost two years now, the demand for baby milk powder could not be covered. Moreover, the demand for German milk powder from third countries has increased strongly.

Amongst other things, this is due to a milk powder scandal in China where babies fell ill and even died because of poisonous milk powder.

Better baking thanks to ultrasound

Together with ttz Bremerhaven, European bakeries and equipment manufacturers are developing and distributing an energy-efficient and cost-effective technology for refrigeration and proofing. At the heart of the development is a water aerosol produced by means of ultrasound, which additionally leads to far better product quality, as a new film demonstrates.

Baking is energy-intensive. This not only has a negative impact on the environment but also on the baker’s wallet. That is why the NanoBAK2 research project...

World’s Largest Hydrogen Electrolysis Facility

Siemens and its partners have officially commissioned the world’s largest hydrogen electrolysis facility. The centerpiece of the installation, which is known as the Mainz Energy Farm, is a high-pressure PEM electrolyzer. The electrolyzer can ramp up to its full capacity of up to six megawatts in a matter of seconds, making it ideal for use with the rapidly changing output of renewable generation systems.

PEM stands for polymer electrolyte membrane, and describes a process designed to generate hydrogen using water and electricity. Part of a two-year research...
