The heat radiating off roadways has long been a factor in explaining why city temperatures are often considerably warmer than nearby suburban or rural areas. Now a team of engineering researchers from the University of Rhode Island is examining methods of harvesting that solar energy to melt ice, power streetlights, illuminate signs, heat buildings and potentially use it for many other purposes.

The initial line-up of energy efficient roofing products, includes a solar energy-generating system, a unique ventilation and insulation product, along with steel and aluminum shingles. According to company President Todd Miller, "We are bringing products to market that allow homeowners to invest in and improve their current homes, and do so in a way that benefits the environment."

"You can save 10 to 20 percent of your energy costs just by paying attention to when and how you use energy in your home," said a member of Middleboro's Green Energy Committee. "Then you can save even more by improving the windows and insulation. On top of all that, use renewables like solar or wind to generate your own electricity.

Thailand will be supplied with some more solar panels for a new power plant, as a result of the signed agreement between the authorities and Suntech Power Holding Co. The latter will provide approximately 9.43MW worth of panels to the installation. The project is owned by Bangchak Petrolem and is scheduled to be finalized by the end of next year. Once online, the solar power plant should provide around 44MW of clean electricity

Việt Nam sẽ có nhà máy điện quang năng 500 MW vào năm 2012. Đó là thông tin đang sôi động trên các trang web tại Mỹ. Tập đoàn First Solar, Inc vừa thông báo về kế hoạch xây dựng thêm hai nhà máy năng lượng mặt trời, một tại Mỹ và một tại Việt Nam.Hai nhà máy này sẽ ứng dụng những tế bào quang năng thế hệ mới, siêu mỏng gọi là Nanosolar và Miasole. Kế hoạch này dự định sẽ hoàn thành vào năm 2012 để nâng tổng công suất của Tập đoàn First Solar từ 1,4 GW lên 2,7 GW.

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.

Nhà sản xuất Logitech (Mỹ) vừa chính thức trình làng bàn phím máy tính không dây, chạy bằng năng lượng mặt trời đầu tiên với tên gọi Logitech's K750 Wireless Solar Keyboard. Theo Engadget, Logitech's K750 sử dụng chuẩn QWERTY, và không hề sử dụng bất kỳ dây dẫn cũng như bộ sạc pin thông thường nào, mà chỉ cần bàn phím nhận được một chút ánh sáng ngoài trời là nó có thể hoạt động bình thường.

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.

MIT researchers are hopeful of capturing and releasing solar energy with the help of thermo-chemical technology. Scientists were already working on this technology in seventies but this project was aborted due to its expensiveness and termed as too impractical to achieve. But MIT researchers are now gearing up to take this thermo-chemical technology that is supposed to convert solar energy into electrical energy.

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.

A few days ago, the Israel-based energy company ZenithSolar has officially unveiled its 3rd generation Solar Z20. Being installed in Kibbutz Yavne in central Israel, the solar energy generator is a combined heat and power system, able to deliver 72% efficiency.

The project is following up on a pre-feasibility study conducted by the Clinton Climate Initiative. Fluor’s task is to develop a conceptual master plan to be unveiled at the South African Solar Park Investors Conference (Oct. 28 and 29), which will be held in the Northern Cape Province.

Leave it to larger-than-life Texas to lead the U.S. into a new energy future. While the state is most closely associated with oil, it has also been an early pioneer of wind power, and is beginning to embrace solar energy along with armloads of new green jobs. Now the San Antonio Water System has set the national bar high in the sewage-to-biogas field, by becoming the first water district to hook a biogas facility up to a commercial gas pipeline.

After participating in the GE Ecomagination Challenge and winning $50,000, Scott Brusaw and his wife Julie Brusaw are much more optimistic in what concerns their Solar Roadways project, which aims to make the road produce electricity through embedded solar panels.

In a first-of-its-kind melding of solar technology with high speed rail facilities, the clean energy company Enfinity will install 16,000 solar panels on the two-mile long roof of a rail tunnel in Belgium. If the name Enfinity doesn’t ring a bell it soon will. The Belgium-based company has trained its sights on the U.S. energy market and is poised to step up commercial and utility scale solar installations here, from coast to coast. New green jobs, much?

There are more than two billion people worldwide with no access to drinking water. This is the reason why researchers over the globe are trying to find solutions such as desalination. This reverse osmosis of water is the most efficient and economical form of desalination but the problem is that it needs 3 kWh per cubic meter of water. Solar panels and wind turbines can be used to supply this power.

DOE encourages the growth of these programs nationwide by selecting exemplary programs to receive Green Power Leadership Awards. This year's winners include 3Degrees, Bonneville Environmental Foundation, SolarCity and SunRun – recognized by DOE as the Non-Utility Green Power Suppliers of the Year – and La Plata Electric Association and Portland General Electric – recognized as the Utility Green Power Programs of the Year.
