South Africans concerned about the environment and doing their shopping or out in town can quickly know if the fish they are offered is one of endangered species. They simply provide the name of the fish to a number by SMS to obtain, also by SMS, the information.
With 76 per cent of the world’s fish overexploited or fished to maximum levels, the Southern African Sustainable Seafood Initiative this week launched a text message service that provides information on whether that tender sashimi is from a plentiful or an endangered species. (more…)
The electrician National Eskom has signed an agreement with WWF (Worldwide Fund for Nature) to support the development of renewable energy by companies or research centers, to the tune of 330,000 euros per year for the next three years.
The Danish government is funding a program of study that aims to map wind (speed and frequency) on the 3,000 km of coastline of South Africa. This program provided over a period of four years, starting January 23 next to the organization of an international seminar to promote wind energy, the first card is expected in early 2010.
Meanwhile Eskom has confirmed the start of construction of a 100MW wind farm to Koekenaap in the Western Cape province. This wind farm Koekenaap associated with the existing farm Darling generate just over 0.3% of 40,000 MW of electricity being generated by Eskom. The atlas project winds will be jointly led by the University of Cape Town (UCT, University of Cape Town), Royal Danish National Wind Resource Institute, SANER (South African National Energy Research Institute) and the Department of Minerals and Energy (DME, Department of Minerals and Energy).
The German Federal Minister of the Environment, Sigmar Gabriel, has welcomed the entry of India in the International Agency on renewable energies (IRENA) as a strong signal for the implementation of an energy supply respectful of environment. He believes that “this not done by India is a new impetus for renewable energy. India could also exploit the opportunities that offer renewable energy in the fight against climate change, security of supply and economic development and employment. As an emerging country in economic growth, India may also, by joining the IRENA, to serve as an example for other countries. ”
India has signed on 17 March 2009, the status of the IRENA in Berlin, as the 77th member. In parallel, India has confirmed its intention to contribute to the budget of the organization with more than 110,000 U.S. dollars for the second half of 2009. With this signing, India becomes like all other signatory States, Member of the preparatory committee for the organization. The commission will decide next June on the appointment of the director of the foundation of IRENA and the location of the agency. (more…)
The researchers from six institutes of the RWTH University in Aachen test, in a former power plant, a coal innovative facility that produces electricity just as effective as the current generation of power plants without emit CO2 into the air.
Fossil power plants, which produce electricity from coal, natural gas or oil, have a bad reputation: they emit a large amount of CO2 in the atmosphere and pollute the environment. However, they are crucial in the German energy mix: in fact, renewable energy will not be sufficient to meet the need of electricity in the coming decades. To achieve the European objectives extremely challenging, the possibilities are limited: the existing power plants must be cleaner – and, as soon as possible.
That’s why engineers at the RWTH at Aachen developed under the research project OXYCOAL-AC, a process oxycombustionÃ‚ of coal. The project is funded by the Federal Ministry of Economics and Technology (BMWi) as part of its initiative COORETECÃ‚ by the Department of Innovation, Science, Research and Technology Land of North Rhine-Westphalia, and the industry to 20% of the overall budget. Among the partners are companies such as RWE Power, E. ON Energies, Hitachi Power Europe, MAN Turbo and Linde.
Unlike the usual power, coal in the power-test Aachen is not burned with air, but directly with oxygen. “As in all other power plants, combustion of carbon produces CO2,” says Prof. Reinhold Kneer chair of the heat transfer and mass , one of the six institutes of the RWTH involved in the research project OXYCOAL-AC. “But we try to obtain almost pure CO2 in the residual gas, so you can deal more easily. For this purpose, we use the pure oxygen as the oxidizer instead of air, and able to get out of the combustion fumes are very rich in CO2 (decrease in the production of oxides of nitrogen, for example). In this way, the CO2 is separated more easily and cost-effective products of other compounds in the gas d exhaust. ” (more…)
The total emissions of all greenhouse gases in Germany in 2008 over the previous year to nearly 12 million tons, which is a decrease of 1.2 percent. The total emissions are 945 million tonnes of CO 2-equivalent – and thus within the target corridor of the Kyoto Protocol: After Germany has its annual average greenhouse gas emissions in the years 2008 to 2012 to 21 percent reduction (relative to the base year 1990). According to the present Nahzeit forecasts of the Federal Environmental Agency (UBA), Germany has in 2008 already in the first year of this target range fulfills its commitments and 23.3 percent reduction achieved.
Federal Environment Minister Sigmar Gabriel: “Even if one assumes that presumably 1-2 percentage points this fall due to the economic crisis, so the new figures show, however, that our climate change policy work. Germany is a pioneer in climate protection and the Kyoto targets for three years before reached the finish line. For now until 2020 to achieve the necessary reductions, we have the best price with the expansion of renewable energies and increasing energy efficiency will continue and be persistent. ” (more…)
To determine if the rotor blade of a wind turbine is still intact, or whether it has tiny air bubbles, which grow and could eventually lead to a rupture, infrared thermograph detects quickly and cheaply defects materials.
At first glance, the rotor blade seems impeccable. However, the expert knows that external considerations do not suffice. He dusts the surface and listening. (more…)
A new Fraunhofer research group has been created at the Carl von Ossietzky University of Oldenburg. The Fraunhofer Institute for Manufacturing and Technical Materials Research (IFAM) in Bremen has set up a group of experts in close cooperation with the departments of energy research and research on semi-conductors of University of Oldenburg and the research center EWE NEXT ENERGY. This group will aim to develop components and systems for storing energy for electric vehicles. Approximately 40 employees work at this in a new building of the University.
With this new project, the town of Oldenburg is one of the search sites are most important for the future of energy in Germany, as witnessed by the Minister for Science and Culture of Lower Saxony, Lutz Stratmann. The research and development center is established and the potential involvement of Bremen and Lower Saxony and strengthen the institutional synergy – a milestone not only for the energy technology sector but also for the economic development of the north-west Germany.

The diamond is the mineral as found in nature. There is no known material of greater hardness on Earth, so in order to carve a diamond would have to use another diamond.Depending on the size or form of the diamond, it is called with a different name. For example: if you apply a round size, it is called brilliant cut diamonds. (more…)
VITO studying the environmental impact of biofuels for transport and public service vehicles in Flanders
At the request of the Department of the Environment, Nature and Energy of the Flemish authorities, the VITO (Flemish Institute for Technological Research) analyzed the consumption and emission of three types of service vehicles using the pure vegetable oil (HVP) compared with vehicles running on B5 biodiesel and diesel.
For both vehicles, the alternative of HPV is more respectful to the environment. The HVP generates less CO2 and its use leads to a reduction in the emission of particles. However, the emission of nitrogen oxides (NOx) remains high. The rate of carbon monoxide and hydrocarbons is variable, but is well below the current European standards. The 3rd type of 4×4 vehicle using a biofuel presents a rather negative environment, which is probably due to the fuel injection system. For the three vehicles, VITO measured a high level (up to 15%) of biofuels compared to diesel. (more…)
