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.

New research initiative will power up Europe’s battery revolution

A world moving from fossil fuels to renewable energy will rely more and more on energy storage and in particular on batteries. Better batteries can reduce the carbon footprint of the transport sector, stabilise the power grid, and much more. The Battery 2030+ large-scale research initiative will gather leading scientists in Europe, as well as the industry, to achieve a leap forward in battery science and technology. The first Battery 2030+ project kicks off in March 2019 and will lay the basis for this large-scale research initiative on future battery technologies.

In the Strategic Action Plan on Batteries published in May 2018, the European Commission has highlighted the need to support the European battery industry...

Captured carbon dioxide converts into oxalic acid to process rare earth elements

Until now, carbon dioxide has been dumped in oceans or buried underground. Industry has been reluctant to implement carbon dioxide scrubbers in facilities due to cost and footprint.

What if we could not only capture carbon dioxide, but convert it into something useful? S. Komar Kawatra and his students have tackled that challenge, and...

The holy grail of nanowire production

Nanowires have the potential to revolutionize the technology around us. Measuring just 5-100 nanometers in diameter (a nanometer is a millionth of a millimeter), these tiny, needle-shaped crystalline structures can alter how electricity or light passes through them.

They can emit, concentrate and absorb light and could therefore be used to add optical functionalities to electronic chips.
