Switzerland receives European award for Solar Energy
It is a recognition awarded by the European Association for Renewable Energies (Eurosolar). The Stadium of Switzerland received the award in the category ‘owners and managers of implants for use of renewable energy‘, said Eurosolar.
In the same class are also awarded to the Westfalenhalle of Dortmund. Other winners in the category “Cities and municipalities’ are La Meal (Zaragoza, Spain), the Italian province of Trento and the people June bee Gottingen (Germany).
Back in September, Stadium of Switzerland won the Swiss Solar Prize 2005. The benefits of solar panels on the roof and managed by the company BKW Energies AG achieved, with optimal levels of insulation, the 850 kW.
The maximum annual production of 700,000 kilowatt hours, equivalent to annual power supply 200 households. From a technical standpoint, it could reach an annual production of nearly double, to 1,300,000 kilowatt-hours. Big and small, yet the implementation built on the stadium of Switzerland is the largest solar power plant on the planet, but the broader stage.
The project was developed by the international research center of the Mont Soleil, in the Bernese Jura (northwest). Despite its size, it would take 4,170 such facilities to achieve the production of nuclear power Muhlenberg that, like the panels of the stadium belongs to the BKW.
Several municipalities in the surroundings of Berne have expressed interest in solar energy, and many families through interactive tools and models, combine different energy technologies.
Combining the power production from fossil fuels
Have more clean Energy economic benefits in the short term than their production costs would be far more numerous and frequent in the global energy supply.
But as yet are expensive to produce, while some countries invest in research, others are produced from renewable energies. In the following simulation model (created for the English case the BBC) can “play” to calculate the cost of electricity in our bill at end of month, combining electricity production from fossil fuels (like oil and coal ) with over-or under-production from sources “clean” wind, renewable, nuclear, etc.
The model is dynamic and entertaining, so he brings out in real terms (money) what it would cost today to produce electricity from, for example, replacing 50% of the fossil to renewable energy production.
The wind turbine as an energy source that has an important role
From early in the history of mankind, the wind was used as an energy source (motor for boats or windmills pumping water or grinding). Today we explore its use to produce electricity.
The use of wind turbines to generate electricity on a large scale began in Denmark at the end of the last century and has spread worldwide. Through various components, wind turbine generators use their power to produce electricity.
The turbines are operated when the wind reaches a speed of about 19 to 21 km / h (ie, it takes a wind of at least moderate intensity, a breeze is not enough). When the wind stops, the wind farms use batteries to continue to deliver electricity. The wind turbine generators usually have a standard size (15 to 30 meters in diameter, with a capacity between 100 and 400 kW).
In Denmark and the Netherlands, where land-based turbines are typically located in flat terrain, offshore wind turbines produce 50 percent more energy than those in nearby onshore site. The reason is the low surface roughness of the sea.
On the other hand, the construction and installation of offshore foundations require 50 percent more energy than land. Finally, offshore wind turbines have a longer expected lifetime than onshore turbines, about 20 to 30 years.
The disadvantages of wind turbines are, for many users, aesthetic and environmental. Aesthetic because the presence of wind farms interrupted and disturbed by the vision of the landscape and environmental because the birds die because they can not avoid on your routes the blades of wind turbines. Given these disadvantages, the Danes notes:
Tjaereborg radar studies in the western part of Denmark, where there is installed a 2 MW wind turbine with a rotor diameter of 60 meters, show that birds (either day or night) tend to change their flight path about 100-200 meters before the turbine, and pass over it at a safe distance.
Find information about the nuclear through some places
The majority of waste generated from nuclear applications, but few know what the real result that produces the accumulation of such waste on the planet, and even exist in most countries, certain regulations for handling such waste, are not fully met. On the other hand, we should mention the site or where to find more information forms of nuclear energy, which generally tend to be nuclear plants, since the processes are carried out to obtain this type of energy are extremely complex and to achieve understanding themselves should have some basic knowledge and not so basic chemistry and related sciences.
To begin, we can say that certain books or manuals which includes all information of this type, including also the formulas with the elements, the reactors and the products of each reaction is carried out to obtain nuclear energy, and although we all know that books are the most reliable sources of information, accurate and complete we can find, while not as simple to find books that contain such information.
That is why you can always go to a Web search, although many argue that the web is not always a reliable source of information, there are certain places where you can find exactly the information sought. Anyway, it is important to note that to find information on the Internet should be able to look properly, and make some sense or experience to recognize those pages that are trusted and those that are not.
That is why it is recommended that information should be sought nuclear energy needs, complete and extensive use is made directly to books and manuals can be found in libraries of all types, whether by commission or directly to the sale. If nuclear power sought information less complex, to obtain a basic understanding of the procurement of energy can always resort to the Internet, as well as a public library where if you are a member, or often it is not necessary that condition, you can find all the books and is always required some assistance in finding exactly what you find and make use of the book until it has obtained the necessary information.
How research on solar thermal
The Higher Technological Institute “Catalina Harangue of Brown” runs the Laboratory for Research on Renewable Energy (LIP) since last September. The lip is possible through an agreement by which the National Agency for Research and Innovation (ANII) funds the project in which the UTU offers its premises and that one of them is in Montevideo and the other in Salt. In that sense, there are two people who are hired by the ANII, which are the engineer and technician Ramon Saul Vela Severe, in the area of research.
Within the UTU is working with students who are actively involved in the tasks you do in the laboratory. Consulted on this report, Saul Severe told PEOPLE that the laboratory “work with three types of energies that are most common in Salt: wind, solar photovoltaic and solar thermal. We also have an agro-meteorological station where measurements are made every day. “Severe confirmed that in both cases there are records of temperature, humidity, atmospheric pressure, rainfall, wind chill, and this occurs from August 10 this year.
“It connects a computer to the station and has all the information of every moment of the day, and then compared with measurements made on the panel, and there we have the performance results, how much radiation there, what temperature we have among other data, “appropriated.
According to experts, Salt is located in a geographical point where it gives more sun than the other places throughout the region, which encompasses the departments of Rivera, Arias and part of southern Brazil. According to Severe “solar map Salt located in a suitable, since it has an average of 5 kilowatt hours of sunshine per day during the year (and with that ability) are more than enough.
“With regard to wind energy, which is gaining ground Salt as it is building a plant of this system in the area of Salt Grande by a group of Japanese investors, Professor Severs told us that “with the measurements have done in the agro-meteorological station can say that is not profitable, because to move a small wind generator takes an average wind of 3 meters per second, and there is an average jump of less than 2 meters per second and not is not convenient.” The lips are planning to install a wind generator, which consists of a tower 20 meters high with a mill, along with eight photovoltaic solar panels of various models and types.
How can model hydroelectric
The development of new small-scale hydroelectric plants could be an important new impetus for this type of energy enterprises, according to research undertaken by engineers and scientists from the Technische Universidad Munched (TUM) in Germany. These small plants would be more efficient from an economic standpoint, greener and its construction would be simpler, among other important advantages.
The design of new hydro plants could allow renewable energy generation in thousands of geographical locations in which it is not possible, for various reasons, installing traditional core. In Germany, for example, there are no possibilities of developing hydropower infrastructure.
At the same time, other large-scale hydroelectric projects that are carried out in different countries have attracted criticism because of its profound impact on the environment. This determines the future of hydropower, considered the oldest renewable energy source.

How nuclear power model
The Bolivian president denied that the proposed nuclear plant have military purposes or is linked to the development of nuclear weapons.
“I have no reason to lie: one of the topics we move forward with Iran is obviously having a nuclear plant for energy issues. When we talk about nuclear plant accuse linking it to an atomic bomb, we are not talking about atomic bomb. “
Morales made the revelation one day after noted that during his visit to Iran this week could learn about the quantum leap that led this country in the production of nuclear energy “for peaceful purposes.”
According to the ruling, Bolivia has uranium, the essential raw material for producing and exporting nuclear electricity to neighboring countries.
The Head of State had announced last August the existence of veins of uranium in southern Bolivia, but for the time being no information to establish their potential.
The governments of Mahout Ahmadinejad and Morales have strong ties to political affiliation since the inauguration of diplomatic relations in September 2007.
How innovative solutions to reduce the impact of energy consumption
The pursuit of urban planning requires an actor who has the tools, expertise and experience in order to quantitatively assess this type of action, both in terms of economic investment, and savings of energy and environmental impact.
Aguishly, leading company dedicated to engineering and energy consultancy, offering innovative solutions to reduce the impact of energy consumption, power business area to improve the energy performance of buildings, where he believes can contribute its broad expertise and knowledge.
Jodi Pascal, Aguishly manager, “currently in Spain have the information and technology sufficient to cause a radical improvement in the energy performance of buildings, yet the building sector yet reached its potential for improvement energy.
The regulatory framework in the construction sector is more than ever, favorable to energy efficiency and renewable energy integration. The transposition of Directive 2002/91/EC on the energy efficiency of buildings meant, on one hand, the approval of the Technical Building Code, establishing higher levels of demand in terms of saving energy (DB – HE) and, secondly, the approval of Royal Decree 47/2007, which approved the basic procedure for energy performance of new buildings, which promotes energy sector improving forced to report on the energy performance buildings through the “Energy Label” (similar to domestic appliances). In regional and local level, there is also legislation on the matter with aim of promoting the construction of buildings lower power and renewable energy supply.
“However,” continues Pascal, in many cases it is difficult to act on the proposed buildings, if some issues have not been previously considered at various stages of planning in the land management process. Although these upstream interventions have a greater impact on the outcome, both in terms of primary energy consumption (and associated emission levels) and in economic terms, the introduction of energy as a cross to bear in mind from early stages of urban planning is still a pending issue. “
The pursuit of urban planning requires, by its nature, the combination of various disciplines, and often the knowledge required to incorporate energy efficiency criteria and integration of energy-efficient systems beyond the equipment designers necessarily more general. In these cases, integration into the computer of a figure that has the tools, expertise and experience will be necessary.
