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.

Studying how unconventional metals behave, with an eye on high-temperature superconductors

Using laser light to trap atoms in a checkerboard-like pattern, a team led by Princeton scientists studied how resistance -- the loss of electrical current as heat -- can develop in unconventional metals.

The results may help explain how certain types of superconductors made from copper oxides are able to conduct electricity so efficiently. The research was...

Agricultural insecticide contamination threatens U.S. surface water integrity at the national scale

Insecticide contamination of surface waters regularly occurs across the U.S. in concentrations that have severe detrimental effects on aquatic ecosystems. This was found by a recent study by the Institute for Environmental Sciences Landau, Germany. According to their findings, insecticide contamination occurs widespread throughout the United States and risks are expected to increase in the future. This studies shows that insecticides thus threaten one of the most important natural resources and highlights the urgent need to re-evaluate current regulatory practices in the U.S.

Insecticides are applied in large volumes across the United States to protect agricultural crops from insect pests. As has been shown before through studies...

Improving hydropower through long-range drought forecasts

Researchers at the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) have developed a complex hydrological model for forecasting dry spells lasting several weeks with high spatial resolution. These predictions make it possible, for example, to operate hydropower plants more profitably.

Changing climatic conditions pose extra challenges for hydropower plant operators. As part of the National Research Programme “Energy Turnaround” (NRP 70),...

15-meter roll-to-roll device is world’s longest OLED

Working within the framework of Lyteus, Holst Centre and Fraunhofer FEP step into the spotlight with the creation of the world’s longest single-device OLED. At a stunning 15 meters in length it opens the door to ‘endless OLEDs’ that manufacturers and designers can then easily tailor to their own needs.

Lyteus brings together leaders in OLED technology from across Europe to create a pilot production line and product development services for OLED products.

Working together for the industrialization of bipolar batteries with Lithium-ion technology

Better batteries for a greater range of electric vehicles – this is the goal of the “EMBATT-goes-FAB” project sponsored by the Federal Ministry for Economic Affairs and Energy. For that reason, the four project partners thyssenkrupp System Engineering GmbH, IAV GmbH, Daimler AG and the Fraunhofer Institute for Ceramic Technologies and Systems IKTS are developing bipolar batteries and processes for their fabrication.

Thanks to their unique stacked layout, a higher storage capacity and, ultimately, a greater range of the vehicle are achieved using the same surface area.
