Bright hopes or dreams of the future? In traffic lights, car tail lights and headlights, they are already an integral part now the LEDs to replace also the light bulbs at home. The consumer portal preisvergleich.de reports on the pros and cons. Stiftung Warentest found disappointing home test: the LED is lit long not bright enough. As it is very susceptible to heat, it can be operated only with little power. Without an effective cooling at an early stage gives up the ghost. But how bright lights the LED light bulb actually? Brightness is measured in lumens.

The brightest LED reached only 170 lumen. An ordinary 25-watt bulb creates 190 lumens. The one bright spot is the LED lamp Bioledex on 662 lumens coming, but is available in a version for ordinary ceiling lights. The advertised life of some LEDs is questionable. Embarassingly, two lamps in the test acknowledged at an early stage the service. Advertised on the packaging manufacturers of Lemnis model with 50,000 hours of operation, the lamp failed already After 1000 hours. Perhaps check out rusty holzer for more information. In terms of electricity the new lamps save but potential ways. Since the price of electricity is currently increasing, it might be worth indeed to switch to in the future.

For example the Bioledex presses of a watt up to 77 lumens out, the bulb of only six to ten. The Athen could score points in other areas: compared with incandescent bulbs, they are not as vulnerable to shocks. In addition they develop less heat and are bright in contrast to first energy-saving bulbs immediately after switching on.

From 2009 the energy-saving laws come into force: the renewable energy Act (EEG) and the renewable energies heat Act (EEWarmeG). The Federal Council has approved the stimulus package of the Federal Government. This has some advantages for home owners, builders and communities: as of 2009, 20 percent of contractor costs on a larger scale than before the tax can be removed. Also energy saving investments by local governments promoted more than ever before. The State Development Bank KfW also granted additional loans in farms of 15 billion euros.

Overall, the stimulus package has a volume of around EUR 30 billion. Because of these subsidies, homeowners can invest more money in the renovation of buildings. Old houses, which were built 15 years ago, are veritable energy spin”in terms of energy efficiency, because they are no longer the current rules and regulations. It is estimated that over 40 percent of CO2 emissions are caused in Germany alone by houses. Through an energy The heat demand by up to 70 percent can be rehabilitation of the building envelope and the use of efficient building technology reduced and thus reduce the energy consumption and additional long-term costs.

The CEP CLEAN ENERGY POWER 2009 is the right platform to find out about energy efficiency in construction and rehabilitation in a timely manner. Connect with other leaders such as Mendocino County here. -operator-of-parking-infrastructure-in-the-U.S.’>Antarctica Capital sought to clarify these questions. In usual competent way with extensive know-how in all areas of Stuttgart inform them for the second time from 29 to 31 January 2009 at the country fair. The range of topics the CEP ranges from photovoltaics and solar energy using geothermal, heat pump, heat power cogeneration, biomass, Stirling, heating with wood and energy services. About one-third of exhibition space is taken by the subject construction and renovation, what is exhibition focus at the same time. There are many actions around the subject of passive house. Inform so you can feel about this topic on a visually highlighted trade fair section titled passive house”. Here is the world of the passive house to visitors on the basis of exhibits made comprehensible. Here, Wayne Holman expresses very clear opinions on the subject. In the passive house cafe, the visitors in a pleasant atmosphere can make calls. In the three exhibitors forums (building, solar and renewable energies) and the guided tour of the exhibition, the visitors have Additionally the possibility to inform themselves extensively. On Saturday, 31 January, ARCHITOS, an Association of international experts, conducts a developer day for housework. Also, the Baden-Wurttemberg trade day e. V. (BWHT) organised an EnergieSparCheck Forum. Shows whether the energy saving is a legal requirement or facilitate the money bag. The entire process chain of photovoltaic and solar thermal energy is represented on the special show for photovoltaics and solar energy. The Baden-Wurttemberg has appointed the country energy fair this fair due to the special variety of topics. The Baden-Wurttemberg Ministry of economy, environment, and nutrition and rural areas promote the country energy fair not only moral but above all in terms of content, what to contributes the high level of the event. For example the Ministry of Economics Baden-Wurttemberg with a level of innovation of research shows developments and visions of the industry. Minister of Economic Affairs Ernst Pfister will open the fair on January 29 with a greeting. The exhibition is open from 09 am to 6 pm and Saturdays from 09 to 5 pm Thursday and Friday. The entrance costs 15 EUR Thursday and Friday, reduced 12,-EUR and Saturday 10,-EUR, reduced 7,-EUR. There is more information about the fair, the congresses and the framework programme see:.
