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.

Pablo Sanchis solves the detection of the “island effect”

The “island effect” is one of the main problems in photovoltaic compound solar systems. The doctoral thesis of Pablo Sanchis, presented in the Public University of Navarre (Basque Country), proposes three main contributions: the first one is a new control strategy of a booster inverter for autonomous systems; the second one is a new implementation of impedance measurement method, and the third one, a new methodology for the design of drift method in frequency, which guarantees with t 11.11.2002 | nachricht Read more

Reactor research could save money on nuclear waste handling

Recent experiments by Sandia National Laboratories researcher Gary Harms and his team are using a new Labs-built reactor to provide benchmarks showing that spent nuclear fuel — uranium that has been used as fuel at a nuclear power plant — is considerably less reactive than the original fresh fuel. This could mean significant savings in the eventual safe transport, storage, and disposal of nuclear waste. “The conservative view has always been to treat spent fuel like it just came out of the 08.11.2002 | nachricht Read more

New conductor could provide answers for energy demand

Oak Ridge National Laboratory and 3M Company are hoping for powerful results from a project aimed at making transmitting electricity more efficient and reliable. Researchers from 3M, working with ORNL, are developing a promising replacement conductor for conventional power lines that addresses the problem of power outages caused by sagging lines. Lines sag under the heat of high current loads. The replacement conductor also avoids the high cost and environmentally harmful effects of buildin 07.11.2002 | nachricht Read more

UPS Fleet Study Quantifies the Reliability, Low Emissions of CNG Trucks

A large study comparing trucks fueled by natural gas with others fueled by diesel found the natural gas vehicles produced only a quarter of the carbon monoxide emissions and half the oxides of nitrogen emissions of their diesel counterparts. The study was conducted using package trucks operated by United Parcel Service (UPS), which has the nation’s largest private compressed natural gas (CNG) fleet. The study compared the operations, maintenance, performance, and emissions characteristics 06.11.2002 | nachricht Read more

A wheelchair robot developed by scientists at Coimbra University already has a prototype “capable of navigating without colliding with obstacles by commanded human voice”, as professor Urbano Nunes states, the person with joint responsibility, with professor Gabriel Pires, for the team of professors and students of the Electro-technical Engineering Department responsible for the project. For the last five years this project has been developed and integrated in degree classes and pos 30.10.2002 | nachricht Read more

Tokamak fusion test reactor removal successfully completed

One of the world’s largest and most successful experimental fusion machines has been safely disassembled and cleared away. In September, staff at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) completed the dismantling and removal of the Tokamak Fusion Test Reactor (TFTR), which shut down in 1997 following 15 years of operation. During its experimental life, TFTR set records for fusion performance and made major contributions to the development of fusion as 21.10.2002 | nachricht Read more

Tiny atomic battery developed at Cornell could run for decades unattended, powering sensors or machines

While electronic circuits and nanomachines grow ever smaller, batteries to power them remain huge by comparison, as well as short-lived. But now Cornell University researchers have built a microscopic device that could supply power for decades to remote sensors or implantable medical devices by drawing energy from a radioactive isotope. The device converts the energy stored in the radioactive material directly into motion. It could directly move the parts of a tiny machine or could generat 18.10.2002 | nachricht Read more

An ’AAAAAAAAA’ battery? UF researchers make progress on tiny cell

It would send and receive faxes and video and have the processing power of a personal computer. The cell phone of the future would be on the market today but for one hitch: the battery. The technology is available to build cell phones that would make the latest versions -- those that allow users to send pictures and play video games -- seem almost primitive. But the batteries now used in cell phones are not nearly powerful enough to drive all the fancy add-ons, said Charles Martin, a Univers 10.10.2002 | nachricht Read more

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.

Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
