Technology Review: Solar Roofing Materials - 0 views

  •  
    Integrating solar cells into building materials could make solar power more attractive to homeowners. Seamless solar: The solar system shown here (darker panels) integrates thin-film solar modules directly into a metal roof. Such systems offer cost savings in labor and materials and blend well with buildings' designs. Credit: EnergyPeak In an effort to promote the adoption of solar technology, United Solar Ovonic of Auburn Hills, MI, has teamed with a major roofing company to create a metal roof system that generates electricity from sunlight. The partnership offers seven different prefabricated systems, ranging in capacity from 3 to 120 kilowatts. Tests show that the solar roof panels are rugged and can withstand winds in excess of 160 miles per hour.

Texas Wind Farm Uses NASA Radar to Prevent Bird Deaths : TreeHugger - 0 views

  •  
    What do you do if you build a wind farm smack dab in the middle of a major bird migration route, and want to avert the anger of conservationists? Put up a radar system that's designed to shut down the entire thing when it detects a mass of birds on the way. That's what's been done at the 202 MW Peñascal Wind Farm in Texas: System Detects Birds Approaching Four Miles Away The system uses radar originally developed for NASA and the US Air Force to detect birds as far as four miles away, The Guardian reports. When it picks up the approaching birds, it analyzes the existing weather conditions and determines in real time whether those birds are in danger of flying into the blades. The system then automatically restarts the turbines when the birds have passed.

Electricity systems can cope with large-scale wind power: ENN - 0 views

  •  
    Research by TU Delft proves that Dutch power stations are able to cope at any time in the future with variations in demand for electricity and supply of wind power, as long as use is made of up-to-date wind forecasts. PhD candidate Bart Ummels also demonstrates that there is no need for energy storage facilities. Ummels will receive his PhD on this topic on Thursday 26 February. Wind is variable and can only partially be predicted. The large-scale use of wind power in the electricity system is therefore tricky. PhD candidate Bart Ummels MSc. investigated the consequences of using a substantial amount of wind power within the Dutch electricity system. He used simulation models, such as those developed by Dutch transmission system operator TenneT, to pinpoint potential problems (and solutions).

Environmental Factors and Low Cost Propel the European Flywheel UPS Market Forward - 0 views

  •  
    Amid growing concerns over the preservation of the environment, the quest for energy efficient and greener technologies is intensifying in Europe, especially after the signing of the Kyoto Protocol. Green initiatives have encouraged the gravitation towards environmentally friendly technologies such as flywheel UPS systems. The European Commission energy efficiency action plan has also helped drive the uptake of flywheel UPS systems. New analysis from Frost & Sullivan (http://www.powersupplies.frost.com), European Flywheel UPS Markets, finds that market earned revenues of over €25.4 million in 2007 and estimates this to reach €58 million in 2014. "Although the technology has been in existence for a long time, it has seen widespread acceptance and increased uptake only over the past three or four years," says Frost & Sullivan programme manager Malavika Tohani. "Flywheel UPS systems use kinetic energy, eliminating harmful emissions and disposal issues and reducing the impact on the environment."

Major gas utility warms up to residential solar thermal - 0 views

  •  
    olar domestic hot-water systems don't grab as many headlines, probably because they're not considered as high-tech as their solar PV cousins, where science is pushing the boundaries of sunlight-to-electricity conversion. I'm always surprised that residential solar thermal systems don't get much attention in the United States, particularly in the south where many homes have swimming pools (that need heating) and where the sun shines warm all year, making the payback dramatically better than PV. In Canada, where the conditions are less ideal, we seem for some strange reason to have a greater appreciation for rooftop solar thermal systems, and indeed, have many startups, such as EnerWorks, and academics spending considerable time improving on the technology.

Peak Energy: World's Largest Solar Power Tower Commissioned - 0 views

  •  
    REW reports the world's biggest solar thermal tower has opened in Spain - World's Largest Solar Power Tower Commissioned. Abengoa Solar has begun commercial operations of the world's largest solar power tower plant, a 20 MW installation. The company claims that the performance of the power plant, the so-called PS20, has exceeded its design output in the wake of its three-day production and operational testing period. Located at the Solúcar Platform, near Seville, Spain, PS20 is the world's second power tower plant in commercial use and features a number of significant technological improvements with respect to its predecessor, PS10. These enhancements include a higher-efficiency receiver, various improvements in the control and operational systems, and a better thermal energy storage system. PS20 consists of a solar field made up of 1255 heliostats with a surface area of 1291 square feet each. This reflects the solar radiation it receives onto the receiver, located on the top of a 531 foot-high tower, producing steam which is converted into electricity generation by a turbine. Plant construction was carried out by Abener.

Green Car Congress: S. Korea Announces Energy Efficiency Initiative; 16.5% Increase in New Vehicle Fuel Economy by 2012 - 0 views

  •  
    The South Korean government has allocated 18.3 trillion won (about US$14.2 billion) for an energy efficiency initiative that will run until 2012 and save 34.2 million tonnes of oil equivalent (toe). The goal is an 11.3% improvement in energy efficiency by 2012, compared with the level seen in 2007. Among the steps are a 16.5% increase in new vehicle average fuel economy by 2012. In 2004, South Korea replaced its voluntary, unenforced standard with a mandatory program-the Average Fuel Economy (AFE) system-that started in 2006 for domestic vehicles and will start in 2009 for imports. (Earlier post.) The current standards are 12.4 km/l (29.2 mpg US) for vehicles with engine displacements of 1.5 liters or less and 9.6 km/l (22.6 mpg US) for vehicles with engine displacements of more than 1.5 liters. Credits can be earned to offset shortfalls.
