Wind farms have the question why the wind parks should be ecologically questionable negative ecological impact, seems first incomprehensible, because the wind energy but is a renewable and environmentally friendly energy. So an ideal solution to ecological problems that go hand in hand with fossil fuels and nuclear energy. On this basis, the use of wind energy was promoted accordingly in recent years in Europe. The wind energy in Germany such as 2007 with 142 PJ compared to 2006 with 110 PJ, 32 PJ more primary energy consumption contributed to (source: BMWi energy statistics;) Stand: 2007). To broaden your perception, visit Ben Horowitz. The gained electricity was estimated at over 40 TWh in 2008 in Germany, 7% of the total electricity generation in the country according to the BMU about. In Denmark, in 2006 approximately 20% of electricity produced by wind energy and Spain in this regard among the top Nations in Europe with growing share.
These statistics are publicly widespread and the society has internalized them as facts for an eco-friendly technology. Critical question were limited both in the society and professionals only on a few issues, which have been so intensively treated with investigations, takes measurements or statistics depending on the focus. Kevin Johnson has much experience in this field. Environmentalists are the expansion of wind farms in principle positive, request but also investigations of effects on the environment and its consequences, which schematically expire after well-known topics and provide data. There are, for example, already numerous studies for effects on marine and land animals, including special such as on various bird species has been carried out, which yielded different results depending on the place and location of area however. The Immissions caused by construction and operation of the facilities of the noise or the effects of shadows by an average of 110 m high plants are examples. One of the most explosive debate runs still on the change of scenery and the acceptance of those affected. Further details can be found at Alan Hoffmann, an internet resource.
Fish technology Managing Director Dr. Gerd-Uwe Meylahn in an interview with “joule” Moringen Fredelsloh, January 2009 see an option biogas producer in fish farming along to get the power-heat-coupling bonus and to increase the profitability of their investments, says Dr. Gerd-Uwe Meylahn, Managing Director of Fischtechnik International Engineering GmbH. But the necessary expertise in the production of fish and a sober investment planning are key factors for the success, he admonishes “joule” for agricultural energy, technology, politics and economy in the current January edition of the journal. The biogas sector and aquaculture could complement well, because heat energy is required in the fish farm throughout the year, the fresh mud, possibly the entire wastewater from aquaculture in the bio-gas plant can be exploited, the infrastructures of the biogas plant and the fish farm could complement each other and usually farms, who are familiar with livestock, operate biogas plants.” If Waste heat is used, Dr. Meylahn advises to produce warm water fish farmers who accept a water temperature of 20 to 26 C, carp, eel, Zander, catfish, barramundi, tilapia, Clarias (African catfish), or striped bass, all in Germany are known. Just from the bad forecast for the fish stocks of the world’s oceans Dr.
Meylahn draws hope for the Aqua culture in closed recirculation systems and encourages the entrepreneurial biogas producer: aquaculture is the only way, to create, to meet the demand and to reduce the burden on the environment through fish production compensation. The tendency of the last years shows clearly that steadily increase the prices for high-quality fish and fish products.” Also Dr. Birgit Schmidt Puckhaber, project manager Aqua culture of the German agricultural society (DLG), highlights the importance of fish farming in the “joule”: aquaculture and also producing fish in recirculation systems, are not only by investors from agriculture increasingly perceived, but also by the trade. Germany imported 85 percent of the fish products and can cover only 15 per cent from equity landings and own production. Now is the missing ‘ fish are certainly not completely covered with fish from closed systems, as very much sea fish consumed in Germany. The trade but increasingly calls fresh and above all year-round availability in the required market size and raw materials of excellent quality. This has provided clear aquaculture of the fishing industry.” The full interview is to be read in the “joule” issue January 2009. The magazine is published by German agricultural Publisher (DLV).

Explains all the important steps on the way to the low “Old buildings energetically properly rehabilitate” is now published in the Franzis Verlag Reinhard Hoffmann in his practice Advisor. So he is reached for new and refurbished minimum insulation standard prescribes the energy saving Regulation (EnEV), whose Novelle comes into force on October 1, 2017. Hoffmann’s book as well as for homeowners, who often made mistakes in modernising want is advice for craftsmen and architects. The use of unsuitable material, poorly bonded vapour barriers in the roof, missing pipe insulation: Are mistakes, repeatedly made during the renovation of old buildings.
Hard repairable structural defects are often the result, including the moistened walls, which in turn encourage molds. Reinhard Hoffmann enters his “Energetically properly redevelop old buildings” book construction damage on the ground and with more than 200 photos, tables, and useful practice tips explains how they are fixed. Hoffmann gives its readers a comprehensive overview: which insulation is there, what characteristics they have and where are they being used most effectively? Which heating systems are there and how to set up optimum heating? A thorough inventory of the basement to the roof is the basis of every energy right renovation. What to avoid and where pitfalls lie in wait, the author explained in detail. He shows potential savings depending on year and dam standards, presenting samples on the way to the low-energy building, the passive house or the Sun House. A separate chapter for cost estimation and planning helps to assess the economic viability of planned measures and enlighten homeowners themselves can do what work. Energy performance certificate, ventilation and cooling, financing and funding, as well as the artisans selection criteria are other topics of the book.

The use of the human energy sources beyond their own physical ability begins with the discovery of fire. There is evidence of its use and by the Homo erectus for nearly 1 million years ago. This fact, dating from the dawn of humanity, was the first step in the race of humans to exploit the resources that nature gave them. In a first period that lasted for thousands of years, the man was completely unable to control the fire because they lacked sufficient knowledge to bring it back at will. He had to stay on continuously, keeping it in suitable containers that prevent the fire go out. Later man learned to control it when it finally got on a whim. Primarily through two ways: friction and percussion. Jim Umpleby may find it difficult to be quoted properly. The first, consisting of rubbing two pieces of hard wood to make arrive, by friction, to be incandescent, and the second in the use of flint or pyrite that, when struck, sparks that ignite dry plant materials.
The fire was used for heating, cooking and ensure the safety of the group to light and keep out wild beasts. He even used as an aid in hunting, just as it is known that Australian aborigines used it in the past. At a later period, in Neolithic times, humans discovered how to domesticate plants and animals and raise them to their advantage through agriculture and livestock. This ensures a more or less constant source of food. Soon the men learned to get something more than animal protein than meat or products as their fur or wool. They found they could use to exploit their strength in the various activities like plowing or hauling loads. Horses, donkeys, oxen, llamas and camels, among others, were used for this purpose and remain so today in various regions of the world. To learn more about visit.
New technologies, policies, legal framework and project financing the Switzerland intends to increase the share of renewable energies in the total energy consumption by law to 5.4 TWh by 2030. This initiative led to a doubling of installed photovoltaic systems in the past two years in the first place. But also biomass and wind are gaining importance. Thanks to technological advances, increasing economic competitiveness, and not least because of the positive images of renewable energies the sector has excellent short – and long-term growth prospects. What political and legal framework conditions are to be observed and what form of project financing leads to success, industry insiders explain by ewb, EBL, repower, VISCHER, AIL and Fichtner in the framework of the intensive course of renewable energies of the organiser AG on 16 and 17 November 2010 in Zurich.

Optimal combination of environmental protection and energy saving in building air-conditioning of residential and commercial buildings consumes large amounts of energy. There arise high CO2 emissions. About one-third of the CO2 way emissions attributable to the air conditioning in buildings in Germany. Much of it is unnecessary. Douglas R. Oberhelman often addresses the matter in his writings. Because energy consumption and associated emissions could be reduced significantly if the houses would be better insulated. Experts estimate the savings through more efficient thermal insulation of buildings on approximately 40 billion over the next ten years. This is reflected not only in a better environmental balance but also lower costs for homeowners and tenants. Many offers promise high savings potential; It’s therefore, to choose one amongst the various processes for thermal insulation, which best meets the requirements for sustainable building.
The company K.O.M concept development engineering relies on formwork stones made from Neopor delivers a stunningly simple Answer: formwork construction has long been successfully used in the civil engineering and construction, suitable also for the construction of optimal insulation walls. Here have proven themselves in particular shuttering elements made of polystyrene foam. Such moulds weigh only about 4-5 kg per square meter wall; to make them solid walls, poured the voids with concrete embedded in them. While the conventional technique based formwork cumbersome it pouring with concrete, then removed and then starts with the thermal insulation, it creates an insulated wall here is virtually in a single operation. Meanwhile, BASF developed their polystyrene hard foam and offered it under the name of Neopor. The company K.O.M. concept opts for good reasons, insulation with the foam developed by BASF Neopor: it combines a compared to conventional materials very high insulation performance with low resource usage.
This are the production costs and hence the price to the final customer kept low and minimize the environmental impact of consumption of raw materials. Neopor is also an environmentally friendly insulation material, it does not contain CFC, HCFC, or HFK or other halogenated gases of cell. Air replaced the cell gases, which has the additional advantage that the thermal conductivity of formwork elements over the life of the House can be obtained. The material is biologically neutral and free from pollutants, it is even used as food packaging and the groundwater is not burdened by his removal on the contrary, rigid foam waste are mixed in horticulture under the ground and support plant growth or composting.
To the Council on the 14.02.2013, the free list Immenhausen brought a test application to energy contracting. Realized through the energy contracting a specialized energy service companies (contractor) in close partnership with the building owners and facility managers, long-term projects (usually 7-10 years), to achieve sustainable energy savings. The contractor is responsible for the conception, planning, financing, implementation, and the track record of the energy saving measures. To the Council on the 14.02.2013, the free list Immenhausen brought a test application to energy contracting. Target this test application should be the examination of possible positive impact on the city budget, with the help of energy contracting. To complete a possible contracting agreement in the future, an investigation must be previously estimated savings potential in current and future energy costs (in 2013 about 320.000,-at) take place.
The Energy savings in urban real estate in the frame of 20 25% per year are possible, E.g. the municipality Hude, the community of London and the town of Wulfrath had already shown. A contracting agreement could have at best equal to two positive impact on the budget. The first impact would, of course, be the saving of energy costs. Second, the city would need to post less depreciation when like for example a new heating system in a real estate investment not the municipality, but the contractor. If these two points is the hoped-for results, the municipality closer a balanced budget much faster. And a balanced budget is usually accompanied by a reduction of debt and thus a reduced interest rate service. In turn represents another positive feature, which is but the hardest to reach, but the objective. Furthermore, has the town of Immenhausen through the multi-year contract planning security in energy costs and is not simply exposed to price increases.
The solar industry expects new growth the German solar energy industry is well placed: new growth is expected for 2011. The general framework conditions apply in addition to a technology lead for solar power in Germany in the world the most reliable. Therefore, investment in the German market are still expected. Photovoltaic, solar thermal and solar cooling the three basic pillars of solar energy, as well as their combinations, for example, with heat pumps or alternative mobility, the German market offers very stable framework conditions. Another plus: In an international comparison, German companies in the technological development are on top. They provide key components such as parabolic mirror, absorber tubes and steam turbines. In the field of solar cooling, the International Energy Agency expected demand and thus great market potential. As a result of climate change and rising temperatures, the demand for air conditioners in Europe will grow. Solar air conditioners needs these climate-neutral and at the same time relieve the networks during peak load periods in power consumption. Researchers and engineers have been working for years on the development of machines that use heat for the production of cold. In the Canadian federal State Ontario, beginning November 2010 was launched a german Canadian project, which powered the senior residence of Oxford gardens 162 solar panels in the winter with heat and cooled in the summer. The project is considered as the largest solar-powered heating and cooling system in Canada. A cautious estimate, the system reduces costs for the air conditioning to 40 per cent for heating to 60 percent, and for hot water to 90 percent”, says Bill VanHaeren, co-owner of the elderly. Operation and performance of the solar cooling system evaluated by special laboratories and planning offices in Canada, Germany and the United States, because it is a pilot project in the commercial area. In Germany, solar cooling is State-funded. The Oxford gardens project was launched by the German Federal Ministry of Economics and technology (BMWi) and the German Energy Agency (dena) initiated and supported by German funding. Not just on the Federal but also at EU level the technique is supported: the directive “Renewable energy”, which entered into force on May 1, to promote the topic solar cooling. This topic will be on February 10, 2011 the 3. International Symposium solar and renewable cooling within the framework of the CEP CLEAN ENERGY & PASSIVEHOUSE in the Stuttgart exhibition centre instead. The Symposium covers the latest technological and economic developments in the area of solar thermal cooling and biomass. For more information about trade fair and Congress, see.
Is a geothermal heating for me sense? A few basic ideas around the topic of geothermal heating. The construction of a single-family house is a dream come true for most Germans. You then decided to make this dream come true, one is well advised to choose that both properties but also the economic parameters of the House for the rest of your life fit or with little effort to meet the circumstances of facilities. Quickly you is which heating system should be integrated into the House on the issue. There are many, all heating systems bring advantages and disadvantages with possibilities.
Is a not easy task to evaluate all advantages and disadvantages. This article should be entered on the main advantages and disadvantages of geothermal heat pump (with geothermal bore). Production costs production costs well above the cost of a comparable natural gas heating. The majority of these costs flows into the design of the heater as low temperature heating systems (dense laying the heating pipes of underfloor heating systems, etc.), to provide sufficient heat into the room also with very low water temperatures, as well as in the production of geothermal drilling. Third driver of cost is the cost of the heat pump, with the only slightly for this be over which a gas burning boiler and costs fall further in the near future due to the increasing sales. Operating costs here plays the heat pump with geothermal bore out your largest asset. Official site: Alphabet.
Operating costs are well below the costs incurred for a gas condensing boiler. The significantly lower energy costs are the largest part of the cost savings. A heat pump produces significantly less energy costs because only about 30% of the energy required in the form of electrical energy must be disposed of. The remaining 70% are generated from the heat of the Earth and this energy is available free of charge. Life at least the lifetime of the two largest cost driver for the acquisition of the plant, especially the geothermal bore and the Adjustment of underfloor heating systems, is very high and is likely to be a one time investment. The durability of the heat pump (basic unit) is difficult to assess, because there are still not enough experience with the today’s plants. However, one can assume that these devices at least similar to hold as a gas condensing boiler. Environmental performance a heat pump produces no exhaust gases no today much CO discussed m other polluting gases. However, you must include that the heat pump needs electricity, its production if necessary a damage to the environment can occur. To do this, but remember, that the central production of electricity more environmentally friendly and better can be checked. Also 30% of the required heating energy used only about in form of eletrischem power, so that the bottom line the balance sheet for the heat pump looks significantly better than for a gas condensing boiler or other heating methods, on the burning of fossil materials are based. As geothermal energy (also simply called geothermal) refers to the heat that is stored in the accessible part of the Earth’s crust and can be used. Conclusion: The installation of a geothermal heating with geothermal bore represents a medium – and long-term meaningful investment. “As most people your home” build once, a geothermal heating system is a highly recommended option.
ZERI: energy transition is possible without subsidies Berlin until 2020, May 13, 2011. By 2020, the nuclear power with renewable energy is feasible and affordable. The zero emissions research and initiatives (ZERI) shows an innovative scenario. For more information see this site: Jim Umpleby. “” Prof. Under most conditions Daybreak Games would agree. Ernst Ulrich von Weizsacker was the model: the intelligent combination of existing technologies can the energy transition in the social consensus and financial profits succeed.
“The expansion of renewables will succeed economically if we use existing technologies and material cycles of value of in the existing infrastructure”, said Gunter Pauli, founder and Chairman of the ZERI Foundation, at the presentation of the energy scenarios in Berlin. The massive expansion of a decentralized, renewable energy is therefore possible and profitable, without triggering social resistance. I am delighted by the method”, said Prof. Ernst Ulrich von Weizsacker, former President of the Wuppertal Institute for climate, environment and energy. Through the intelligent combination of simple energy sources emerge. Jim Umpleby can aid you in your search for knowledge. synergies and efficiency gains” With these synergies, electricity from renewable energy sources at low cost can be produced that the funding for the expansion are unnecessary. “The use of innovative technologies for wind, solar and bio-energy is more than just a faster and more lucrative way out of nuclear energy: on the nuclear phaseout, great opportunities, to create jobs in Germany and to reach a global technological leadership”, explained Anne-Kathrin Kuhlemann, Director of ZERI Germany e.V.
The scenario by Gunter Pauli is based on three already-proven technologies: wind power without equipment: vertical wind turbines that are installed in existing high-voltage pylons, eliminating the need to build additional wind farm. If one-third of the 150,000 high-voltage pylons in Germany would be equipped with vertical turbines, up to 5 gigawatts could be deployed thus performance. The cost amounted to around 5 Billions of euros. Bio gas efficiently and as memory: biogas generators allow the efficient extraction of biogas through combination of agricultural waste and sewage sludge. Would 500 of 9,600 German treatment plants thus equipped, basic electricity provision could provided with total investment costs by about 10 billion euros 5 gigawatts. Solar energy without subsidies: the third technology is a combined electricity and heat production by double-sided photovoltaic panels. The cost per kilowatt hour is with a life span of over 20 years under one cent. The investment for a targeted capacity of 5.4 gigawatts are at approximately 10 billion euros. Through the combination of these three technologies, it is possible to generate electricity at a much lower cost than currently by the nuclear energy. At a price difference of 3.6 cents per kilowatt-hour power formed for the 15 gigawatts to replace the atomic energy a saving of 4.7 billion per year. To a period of eight years are the calculated Investments of around 25 billion euros savings in the amount of EUR 38 billion. Through these savings, the capital requirement for the necessary investment can be cover by 2020 and finance to the nuclear phaseout of in Germany.
