objavio 4. pro 2012. 04:47 Nepoznati korisnik   [ ažurirano 4. pro 2012. 04:49 ]

Vlada RS je na  seji 28.11.2012 izdala Uredbo o spremembah Uredbe o podporah električni energiji, proizvedeni iz obnovljivih virov energije.

V Sloveniji je na omrežje skupno priključenih čez 210 MW fotovoltaičnih proizvodnih naprav.

Predlog za spremembo Uredbe o podporah električni energiji, proizvedeni iz obnovljivih virov, prinaša spremembo višine podpor za fotovoltaične proizvodne naprave, ki bodo priključene na omrežje po 1.12.2012.

Podpore bodo znižane za 63,89 % glede na referenčne stroške določene v letu 2009, ko se je začela izvajati podporna shema, kasneje  se bodo po tej spremembi uredbe še mesečno zniževale za 2 %. 

Zaradi mesečnega zniževanja podpor za fotovoltaiko je določeno, katero višino referenčnih stroškov mora upoštevati agencija za energijo, ko odloča o upravičenosti do podpore.

V Sloveniji se lahko postavi fotovoltaično proizvodno napravo do moči 50 kW že za 1350 EUR/kW (cena brez DDV). To pomeni, da je potrebno referenčne stroške določene v letu 2009 znižati za 63,89 %.

Na osnovi več pobud, da se razdelijo proizvodne naprave v več razredov po moči in se na novo določijo referenčni stroški, ki so podlaga za podporo, je po novem določeno, da se za mikro fotovoltaične proizvodne naprave do 5 kW, ki so priključene za števcem v stavbi, doda bonus 5 % zaradi pozitivnega vpliva na omrežje, ki ga v takih primerih ni potrebno krepiti in razširjati.

Sprememba podporne sheme bo imela učinek na proizvodne naprave, ki jih bodo investitorji priključili na omrežje po 1. 12. 2012.

Po podatkih prejetih z Javne agencije RS za energijo so do 24. 10. 2012 skupno izdali deklaracije že za 190 MW fotovoltaičnih proizvodnih naprav, medtem ko je Akcijski načrt za obnovljivo energijo predvidel da bo konec leta 2020 v Sloveniji postavljenih za 139 MW fotovoltaičnih proizvodnih naprav. V Sloveniji je na omrežje skupno priključenih čez 210 MW fotovoltaičnih proizvodnih naprav.

Zero Energy Home helps say goodbye to energy bills forever

objavio 28. sij 2012. 04:56 Nepoznati korisnik

Denver-based New Town Builders have created a net zero energy house that has designed to save a lot of energy and help preserve precious resource. The Zero Energy Home will leave eco lovers in a state of complete amazement as it takes energy efficiency to an all new scale. 

The builders kept in mind a few things while coming up with this environmentally friendly home. The basic frame of each home will be swapped into an insulating envelop. The roof will come wedged with photovoltaic electricity generating system, which will power the house. This makes sure that the outside cold is completely blocked, and the inside remains comfortable for dwellers. The water heaters, furnaces and air conditioners are highly efficient, which adds to its clean and green status. The construction style makes sure that seven percent or less cooled/heated air gets lost, thanks to the heating and air conditioning ducts used that will be tightened from time to time.

The Zero Energy Home will easily produce the amount of energy it utilizes in a year's span, which can be measured with the help of HERS rating or Home Energy Rating System. The Zero Energy Home will have a zero HERS rating, which is worth applauding. The home will be as comfortable and attention grabbing as an everyday home and will simultaneously be cost effective as well. It won’t burden owners with unusual or complex systems that require regular maintenance and monitoring. The outside wall of the eco coated home will be well sealed and insulated so that no energy escapes. This will be achieved by spraying foam having a thickness of 1 inch.

The windows will have a decreased U value because of which they will become all the more energy efficient. The house will have energy star appliances, keeping up its efficiency. It will feature a 16 SEER or improved air conditioning system, furnace, tank less water heaters, a fresh air ventilator and an energy recovery exhaust fan. The house will sparkle with the presence of 100% LED and CFL lights, which will further save energy. Additional kilowatts of energy will be generated by the presence of extra photovoltaic panels. So, save energy and live a guilt free life while cutting down on your electricity and gas bills.

German Solar Output Increases by 60% in 2011

objavio 10. sij 2012. 01:28 Nepoznati korisnik   [ ažurirano 10. sij 2012. 01:30 ]

Just weeks after the solar industry installed the one millionth system in Germany, the country’s solar trade association announced that the technology accounted for 3% of total energy generation in 2011 — increasing 60% over 2010 to 18.6 terawatt-hours (18.6 billion kilowatt-hours.)

Even with changes to the feed-in tariff that have reduced solar photovoltaic installations compared with previous boom years, the sector was still the fastest growing among all other renewable energy sectors in 2011, according to preliminary figures.

This follows data released last week showing that renewable energy accounted for 19.9 percent of electricity production in the country in 2011, growing 16.4 percent over 2010. Meanwhile, overall energy use in the country fell 4.8% due to warmer temperatures and increasing efficiency efforts, further boosting the value of solar generation.

Facebook’s New HQ Will Be Solar-Powered

objavio 1. pro 2011. 00:16 Nepoznati korisnik

The world's largest social networking site recently announced plans to utilize more renewable energy to power it's new Menlo Park, Calif., headquarters.

Last year, Facebook was scrutinized by its users for using coal to supply the energy for its massive data centers. The company responded by reminding the public that power for its newest data center would come from multiple sources, including renewables, and would be one of the most energy efficient in the world.

But it's clear that some of that negative attention made an impact on Facebook decision makers.

The company recently announced that its newly acquired headquarters would utilize solar power for both electricity and hot water generation. The 24-module system to be built by Cogenra Solar will sit on the roof of Facebook’s 10,000 square foot fitness center, powering exercise machines and heating water for showers. SF Gate has more on how it will work:

"Cogenra's technology is designed to use energy that other solar set-ups waste. Photovoltaic panels absorb a small fraction of the energy the sun throws at them, typically 15 to 20 percent. The rest is wasted as heat. Cogenra arrays, however, run fluid-filled tubes behind the solar cells, with the fluid absorbing some of the heat cast off by the cells. The fluid - a chemical compound kept in a sealed loop - then transfers the heat to water. Curved troughs of mirrors concentrate sunlight on the cells, while motors keep the troughs pointed at the sun as it arcs across the sky."

The solar system will only be able to generate about 10 kw of electricity and 50 kw of thermal energy, which makes it fairly small as far as commercial arrays are concerned. But Facebook director of global facilities John Tenanes said the company could later expand the system, perhaps using the hot water in on-campus cafes. He described the Cogenra system as Facebook’s initial investment in solar power.

Since Facebook shows no signs of slowing down any time soon, we applaud them for this small but significant first step. We only wish more mega-corps viewed renewable energy as an investment instead of a burden.

Germany takes just a decade to reach 1 millionth solar PV system installed

objavio 29. stu 2011. 00:05 Nepoznati korisnik

The 1 millionth solar PV system installation milestone has been declared by the German Solar Industry Association (BSW-Solar). Having launched the 1,000 rooftop program in late 1990, its now just over a decade that a system on the roof of the Institute for Sports Equipment Research and Development (Institut für Forschung und Entwicklung von Sportgeräten - FES), in Berlin marked the 1,000,000th system installed in Germany. In contrast, London, England has over 3 million homes but only just over 3,000 installations since the feed-in tariff was introduced in April, 2010.

“Photovoltaics have developed dynamically and become a key pillar of the energy supply,” said Günther Cramer, President of the German Solar Industry Association. “Significant price reductions for solar power systems have been made possible by increases in production volume and by technical advances. Already in the near future, the generation of solar power will become one of the most affordable energy forms out there.”

BSW-Solar reiterated that it expected approximately 5GW of new installations in 2011, generating a cumulative installed base of approximately 22GW by year end.

The industry trade association noted that PV in Germany covers approximately 3% of gross electricity consumption, but expects this to have reach 10% by 2020.

The current world scenario demands sustainable and Eco-friendly architecture so that we, the citizens of the world, can benefit from them in the future. With similar thoughts, certain architectural designs have been created that stand out as wonderful examples of sustainable architecture. 10 such examples of sustainable architecture are listed here for your information.

1. Solar Plaza Fargo
The Solar Plaza Fargo, a mega project in North Dakota in USA, is a great example of sustainable architectural development. This project, built on a sprawling site area of 90,000 sq. ft., has a large solar panel surface in it that's covered by a glass layer. The project houses both residential and commercial use structures. A lot of use of glass has been made in the construction of the structure so as to let natural sunlight enter the interiors of the buildings. The design of the project encourages and allows space for plantations, sun dial and a central fountain.The parametric design helps to harness solar power through the frameless PV solar panels. This makes Solar Plaza Fargo capable of producing 70,000kWh units per month which totals to 850,000kWh units per year which is around half of the total requirement of the project.

2. Charleston sustainable architecture by Wagner
The designer of Charleston, Mathew David Wagner, is a professor at Virginia Tech's School of Architecture & Design who believes in the creation of eco-friendly structures. The design of Charleston includes a group of independent structures that are meant to be used as gathering spaces for different outdoor activities which actually are done indoors. Charleston also includes a range of sustainable elements that boost green practices such as provision for storing storm water, exploitation of natural light, cross ventilation, appropriate shading and high albedo surfaces.

3. Georgian CCHR
The CCHR or Center for Civil and Human Rights in Atlanta in Georgia, designed by Antoine Predock Architect in collaboration with Moody - Nolan and Perdock Frane, boasts of sustainable architecture that includes green roof and photovoltaic cells. The roof garden works as the cooling system of the building while the photovoltaic panels are fitted at the most beneficial solar orientation. The architecture of this building also includes various other Eco-friendly features like holding and filtering rain water. The design of the building aims at fossil fuel consumption reduction, utilization of the mass of the earth for heat exchange and introduction of fresh air.

To be set up in North America, the design includes a photovoltaic power plant which is to generate all the needed power for the building. Not only that, the architecture will also include a 50,000 gallon reservoir that will collect rainwater which then will be treated so that it is suitable for consumption.

5. Lycee Jean Moulin
Lycee Jean Moulin is a school in Revin in France that has been built following green practices. The design developed by OFF Architecture along with Jeans Giacinto and Duncan Lewis Scape Architecture is so off-beat that from a distance it is difficult to locate the structure of the building as it blends so well with green landscape of the hilly location. The terraces of the school are layered by grass and therefore do not break the beautiful, natural, green look of the hills.

6. Project Eco Link
Named as the Eco Link project and designed by architects like Junkai Jian and Jinqi Huang, this is a huge passenger terminal building that is located on a river side. The structure designed in an asymmetrical form with a sloping demeanor allows a lot of natural light inside the building. The building's design allows rainwater harvesting that can be used to meet the water requirement of the irrigation and other plantations and vegetation which are located inside the compound of the structure. The project has solar panels in its roofs that would generate solar power to meet the power requirement of the project.

7. Egyptian Fine Arts Center
This design created for a new Fine arts center to be set up in Helwan in Egypt is a great example of sustainable architecture. The designer, Moatesem Esmat of Mataria Engineering School, has included various green features in this brilliant, futuristic design. While wind and solar energy would be used to power the premises of this fine arts center, provision for rain harvesting has also been looked into. A lot of the place of this design is covered by greenery and the places that are to be used as courtyards include mechanism so as to allow natural light and ventilation.

8. Wuhan Energy Flower
Apart from being an astonishingly beautiful creation, this flower-shaped building designed by Grontmij and Soeters Van Eldonk Architects hosts a lot of efficiently used green features like rainwater harvesting, solar panels attached to the roofs, solar chimney etc. While rainwater harvesting and solar power generated through solar panels help to meet the water and power requirement of the building, solar chimney in the middle of the structure helps to maximize natural ventilation. The rim around the bowl functions as a sunroof and helps to heat and cool the structure. The pistil made in vertical axis wind turbines collect renewable energy for the building. This design is the first one in the entire world to be accredited by the BREEM outstanding award.

9. Sustainable Circular Taiwan Tower
The Taiwan Tower, designed by STL Architects, is the tallest structure in the city of Taichung. This circular tower has been designed to resist the force of wind along with making the most of renewable sources of energy. The architecture of this structure eliminates the need of mechanical cooling or heating of the building thus saving a large quantity of energy. The central part of the tower is lighter and holds lesser material while saving more of energy.
