Dust, dirt, and the occasional bird-bomb can chip away at the efficiency of solar panels. Hand washing is fine for home-scale installations but that can add up to a huge problem for large installations that cover multiple acres of ground or roofs. Now scientists from Boston University have come up with a solution: self-cleaning solar panels based on technology used in missions to Mars.

Đầu năm nay, GE (General Electric) khởi động Ecomagination Challenge – một thử nghiệm mang tính cách tân trị giá 200 triệu USD nhằm khai thác các nguồn năng lượng tái tạo. Dự án được chia làm 3 hạng mục chính: Lưới năng lượng hiệu quả, Nhà ở/ Công trình thông minh và Năng lượng tái tạo.

Struggling Japanese Automaker Suzuki hopes it will fare better in India than it has in the US. To help make sure it does, Suzuki introduced Indian press to a full line-up of clean-burning CNG vehicles earlier this week.

Vinh Phuc has more than 2,200 enterprises, of which two thirds are small and medium. There is a wide variety of industries such as food processing, textile, leather, wood, forestry, paper, and steel. Especially, Vinh Phuc is one of the provinces with the highest output of baked tile and brick in our country. Specifically, with about 900 manual brick facilities over nine districts, Vinh Phuc’s tile brick output is around 900 million pieces per year.

A big energy consumer of Da Nang, in recent years, Hai Van Cement JSC has applied various solutions for energy efficiency and conservation. Hai Van cement is produced with fully automatic and synchronous technological line and equipment built by Krupp POLYSIUS of German.

Người kế vị ngai vàng của nước Anh đã đạt được mục đích ba năm trước đây là biến Clarence House thành trung tâm của mục đích cắt giảm carbon. Một khi các tấm pin phát điện, tòa nhà 180 tuổi này sẽ có mức "carbon âm" vì nó có thể sản sinh nhiều năng lượng hơn cả nhu cầu thiết yếu.

A campaign for energy efficiency has been started in Ho Chi Minh City with the target of saving 10% of energy expenses for each household. The duration for the program is from June 1st to the end of November.

"Our research could pave the way for turning electricity from the atmosphere into an alternative energy source for the future," said study leader Fernando Galembeck, Ph.D. His research may help explain a 200-year-old scientific riddle about how electricity is produced and discharged in the atmosphere. "Just as solar energy could free some households from paying electric bills, this promising new energy source could have a similar effect," he maintained.

The project “Building Energy Efficient Biogas Cellars for Families in Phu Tho Province” was very successful. It was launched by the Phu Tho Center for Industry Promotion, Consultation and Energy Conservation, within the framework of the National Targeted Program on Energy Efficiency and Conservation.

Discovery cho biết, chiếc bánh xe là phát minh của một nhóm sinh viên tại Viện Công nghệ Massachusetts, Mỹ. Họ đặt tên nó là Copenhagen Wheel (bánh xe Copenhagen) vì Copenhagen, thủ đô của Đan Mạch, là thành phố mà xe đạp là phương tiện giao thông phổ biến.

The left side of the chart shows the different sources of energy and the amounts produced. Following the flow of energy from left to right, the pink boxes show where the energy is consumed (electrical generation, residential, commercial, industrial and transportation) while the shades of gray show the amount of energy lost or rejected – often through heat loss.

Nhà máy Beleluane đặt tại tỉnh Maputo đã được khởi công. Nơi đây sẽ sản xuất thiết bị của tấm thu năng lượng mặt trời. Vốn đầu tư ban đầu cho nhà máy này ước tính vào khoảng 10 triệu USD.

A new joint venture research work at Stanford and SLAC National Accelerator Laboratory, supported by Department of Energy and DARPA has come up with a new solar energy conversion process that can potentially double the efficiency of solar cells. Stanford engineers have discovered this new and totally different process to harvest energy from sun.

Trong nỗ lực nhằm tận dụng tối đa các nguồn năng lượng thay thế như sức gió, năng lượng Mặt Trời, địa nhiệt và nhiên liệu sinh học, Australia đã lên kế hoạch xây dựng nhà máy sản xuất điện bằng sức gió (nhà máy phong điện) lớn nhất Nam bán cầu vào năm 2013.

Toàn bộ cấu trúc của AK1000 sẽ được đưa ra ngoài khơi cách bờ 12 dặm rồi dìm xuống lòng biển. Theo Gizmag thì hãng Atlantis đã chi hết 25 triệu USD để thực hiện nguyên mẫu AK1000 và đưa nó vào hoạt động. Hãng Reuters cho biết Chính phủ Scotland lên kế hoạch khai thác năng lượng đại dương để cung cấp điện cho 0,5 triệu hộ gia đình vào năm 2020.

Before joining the cleaner production component in the industry (CPI), during the production process, Ngoc Lap tea factory used to encounter major environmental problems such as high concentration of dust, noise pollution, and smoke from burning coal, which directly affected the working conditions of employees, worsen living condition in the neighborhoods and schools near the factory. The amount of carbon dioxide emission from the plant is about 2,500 tons per year.

Two co-authors Nguyen Trong Kien and Nguyen Van Hoang of Nguyen Hoang Tuy Company (Ho Chi Minh City) have successfully implemented a system for remote control and supervision of public lighting, detection of electrical leak system via SMS. Accordingly, in addition to remote controlling lighting of public lamps, the system is also capable of detecting current leakage status and reporting to the management department for prompt react.

Ocean Renewable Power Company (ORPC), an industry leader in tidal, river and deep-water ocean current energy technology and projects, announced today that its Beta Power System, the largest ocean energy "power plant" ever installed in U.S. waters, has successfully generated grid-compatible power from tidal currents at its Cobscook Bay site in Eastport, Maine.

One of the largest orchards in Massachusetts has just cut its utility bill 80% with a $1.1 million 220 KW solar power plant. The state of Massachusetts helped Carlson Orchards with grants totaling $595,000 to help in the installation of the 1,050 solar photovoltaic panels.

One purpose of developing solar power technology is to support the load for the national grid and enable consumers to use EVN’s electricity at peak hours with price of off-peak hours (price of grid electricity at night is only 500 dong per Kwh, while during peak hour it is about 2000 dong, calculated accumulatively).
