A star-rating system, similar to that used for electrical appliances, will now be a mandatory part of advertising for lease or sale of office space. The scheme is designed to make climate change a more important consideration in corporate decision-making, in part by naming and shaming companies with office space in energy-hungry buildings.

Now that would be a brutal blow for any industry battered by a vicious recession. But it's particularly bad news for the American wind industry, which had defied the downturn by installing a record 10,000 megawatts of new capacity in 2009. New wind capacity had grown an average 39 percent annually over the previous five years and represented 39 percent of all new electrical generation that came online last year.

On days with little wind, Europe may have to rely on Norwegian reservoirs to keep its wheels running smoothly in the future. On the Continent, the concept of Norway as Europe's green battery has caught on -- but is it feasible in practice? The Centre for Environmental Design of Renewable Energy (CEDREN) -- one of Norway's Centres for Environment-friendly Energy Research -- is carrying out the HydroPEAK project to study whether Norway could truly provide Europe's balance power.

South Korea is set to become home to a new $8.2bn offshore demonstration wind project, according to local media. The project, which is slated to be the largest in the Yellow Sea, will be used to test 20 turbines produced by local manufacturers in South Korea, its regional government has confirmed.

A group of us from the NRDC teams in Beijing, San Francisco, and D.C. just visited Shanghai, China to discuss opportunities to collaborate on helping turn an old iron and steel alloy plant into a new "clean energy development zone." The site is one of 12 old industrial sites that China is planning to turn into clean energy development zones. NRDC's China Program will be working with this project to make it as energy-efficient as possible.

A new institute is being launched to help Idaho residents and businesses conserve power and save money. The Institute will evaluate energy-saving technologies to see which ones work best. The program will be run by the Idaho Falls' Center of Advanced Energy Studies, and Otter says it will play an important role in Idaho's energy future.

Dr. Nguyen The Hung from the Institute of Physics under the Vietnam Academy of Science and Technology has contributed to the efforts to realize the above objective by creating a type of power generator using natural light. In 2008, Dr. Nguyen The Hung and his colleagues began a research project aiming to manufacture a type of power generator system using solar energy according to the absorption diffusion principle (with natural light engine).

The Asian Development Bank (ADB) is optimistic that Asia can get the 10 trillion US dollars it needs to finance sustainable energy projects over the next 20 years. The projects will include more efficient use of coal and oil as well as greater reliance on renewable power sources such as wind and solar energy.

General Electric has created new halogen compact fluorescent light bulbs, GE Reveal and GE Energy Smart Soft, that unlike typical fluorescents (CFLs), contain less mercury (only 1 milligram) and don’t take time to warm up, being more efficient.

Making a cellphone battery last ten times longer is a first target for a large research project that IBM, Infineon and a number of European universities unveiled on Wednesday. The new research project, called Steeper, also aims to decrease the energy needs of other electronic devices like TV sets or supercomputers by 10 times when active, and to virtually eliminate power consumption when they are in standby mode.

A new clean tech company called Totempower Energy Systems Ltd. has come up with an easy way to put wind power within the grasp of everyday homeowners. The company is developing new micro-wind turbines that are designed for close quarters and non-disruptive installation, but the real key to getting more micro-wind turbines into consumers’ hands is the company’s “ease of ownership” plan which provides a soup-to-nuts service including site selection and connecting the turbine to the home electrical system.

Solar panels are usually mounted in series, to sum up their voltages, and the resulting power is sent to a large inverter, which transforms the DC voltage into AC. One big issue with this scheme is that if shade falls on one panel, or it gets dirty, the inverter lowers the current of all the other panels, and causing power losses through inefficiency.

Với sản phẩm mới, sử dụng năng lượng hiệu quả của mình, Whisper Tech - doanh nghiệp sản xuất thiết bị đun nước tiết kiệm năng lượng, thuộc tập đoàn Meridian (New Zealand) đang tham vọng đánh bại các đối thủ tại thị trường ấm đun nước đầy hấp dẫn tại Anh. Whisper Tech nói rằng IPO (việc phát hành cổ phiếu lần đầu) tại Euro có thể xảy ra khi doanh nghiệp này đang dốc lực mạnh cho hoạt động sản xuất.

A New Zealand firm is hoping to beat rivals to Britain's lucrative boiler replacement market with its energy-efficient product and says an IPO (initial public offering) in Europe could be on the cards as it ramps up production. Whisper Tech, controlled by New Zealand state power group Meridian, expects to be profitable within a year and is examining its funding options over the next 12-18 months as it moves into mass production.

The Coca-Cola company has been introducing more electric vehicles and other low-emissions trucks into its massive fleet, and now researchers at the Hong Kong Polytechnic University are developing yet another alternative energy option. The team has been working on a solar powered air conditioning system that would significantly reduce or eliminate beverage delivery truck emissions related to cooling.

The Abu Dhabi Distribution Company (ADDC), which supplies electricity to the city and surrounding areas, will have installed digital electricity meters in all buildings by the end of this year, its deputy managing director Abdulrahman al Dhaheri said yesterday. The new meters not only calculate power usage, but also allow consumers to sell their own solar-generated electricity back to the grid.

The United States is on the verge of a solar boom that could provide 4.3 percent of the nation's electricity by 2020, according to a new report from Bloomberg New Energy Finance. There's just a 12-figure catch: Investors need to put $100 billion into the solar industry to keep the generation of solar electricity growing by 42 percent a year for the next decade to expand capacity from the current 1.4 gigawatts to 44 gigawatts.

This is the third day in a row that we are presenting the most efficient lighting systems invented recently. Now, it’s time for another invention from GE, who made a 1,500-lumen LED light bulb and cooled it through a technology used in aviation.

Floating wind turbines are a little more complicated and require higher initial costs. But a new study, Project Deepwater, by the Energy Technologies Institute (ETI) in the UK has found that due to their greater ability to access stronger and more consistent winds deeper out at sea, they are more economically efficient in the long term.

According to Mazda Motor Corp, the new Mazda2 subcompact will have a fuel economy of 30 km/litre (70 mpg) and as the company said, it will become the world’s most fuel-efficient vehicle. Mazda2 is scheduled to be launched in Japan in the first half of 2011, being the first car fitted with SKYACTIV, a technology produced only by Mazda based on next-generation gasoline and diesel engines.
