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.

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.

Located in the district of Yen Thanh, Nghe An, Yen Thanh Tapioca Plant, directly under Engine and Agricultural Machinery Corporation in Nghe An, was established in 2003. During the past six years, the factory has always faced many problems of power consumption, emissions, waste water and environment pollution.

Lãnh đạo nhóm nghiên cứu, Tiến sĩ Fernando Galembeck cho biết: “Nghiên cứu của chúng tôi có thể mở đường cho sự ra đời của 1 loại năng lượng thay thế mới.” Cũng qua nghiên cứu này, vấn đề về làm thế nào điện có thể được tạo ra và biến đổi trong không khí sẽ có câu trả lời.

Should 1kWh of electricity be saved, we would reduce the amount of carbon dioxide emission into the environment by 0.5634 kg, helping mitigate climate change. So saving power should be one of the priorities to adapt to climate change.

One of the largest plants in the area of Chau Khe craft village, Dinh Bang commune, Bac Ninh province, the Xanh Ha Steel Plant sells about 3,500 tonnes of steel billets and 10,000 tonnes of finished steel products each year, consuming more than 4,000 MWh of electricity and about 900 tonnes of coal.

"This is the first demonstration of a new class of biofuel cells," said Shelley Minteer, Ph.D., who presented the report. "When further developed, these devices have the potential for replacing disposable and rechargeable batteriesin a wide variety of consumer electronics and other products. It is the first such device based on one of the microscopic parts of the billions upon billions of cells that make up the body."

"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.

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.

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.

Even though wind energy is a clean and cost-effective source of energy, it does have one slight drawback: no one can control when the wind blows. This occasionally leads to difficulties in matching consumers’ demand for energy with the available supply.

In the 1990s, the solar energy technology was introduced into Vietnam through projects funded by the governments of Spanish, Dutch, French and German. Many solar energy projects have been put into application since then, mainly to meet electricity needs of people in remote and rural areas, where the national grid has not reached. Unfortunately, those above projects are only in pilot scale.

Qua 2 lần tổ chức Entech Hanoi đã thực sự gây tiếng vang và để lại ấn tượng tốt đối với cộng đồng doanh nghiệp hoạt động trong lĩnh vực năng lượng, môi trường trong và ngoài nước.

A group of engineers at Bridgestone America’s Technical Center in Akron, along with students from DeLaSalle School in Kansas City have recently developed a new all-electric car which has been successfully tested on Bridgestone’s Texas Proving Grounds.

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.
