The fact that weather varies unpredictably during the day, causing power production to fluctuate is much more important than the lack of sunlight during the night, because power plant operators know exactly when night time starts, so any other power plant can be scheduled to start for night time operation.

Leading television company Sky opened the doors to its new, state-of-the-art production facility in London earlier this week, which is being hailed as the most sustainable broadcasting facility in Europe.

Germany's solar photovoltaic (PV) industry now employs more workers than steel production in the USA. With over 100,000 "green jobs" in PV alone, around 75 percent of European solar cells and modules as well as countless components are made in Germany. Record-breaking domestic demand is a key industry driver, with 7.4 GWp of PV capacity installed in 2010.

A series of new, larger turbines with longer blades have been launched into the market recently as manufacturers strive to deliver the lowest cost of energy with the next generation of designs. London, UK A trend towards larger capacity turbines with longer blades and larger rotor diameters has been long established, with OEMs continuing to offer existing machines with a range of rotor diameters. But now, a new generation of still larger machines has been unveiled.

The Rome-based Global Bioenergy Partnership today released a voluntary policy for producing and using biomass and biofuels in ways that don’t add to climate change or affect food prices. The partnership, established in 2005 by the Group of Eight nations and five emerging economies, also includes 13 international organizations and institutions.

Dù chỉ có công suất 17W nhưng hãng cho biết ánh sáng nó phát ra tương đương với một bóng huỳnh quang 75W. Không những thế, bóng đèn LED mới cũng tiêu thụ ít điện năng hơn tới 80% so với một bóng đèn 75W.

Two Citroen C1 models fitted with the inductive system as well as a standard plug-in charger will form part of the Coventry and Birmingham Low Emission Demonstrators (CABLED) consortium testing programme, which comes under the umbrella of the Technology Strategy Board's £25m Ultra-Low Carbon Vehicle Demonstrator competition.

Facebook’s new, state-of-the-art data center is situated on 120 acres of land in Central Oregon. The campus will be completed in two phases, each consisting of 150,000 square feet of data warehousing space. Phase I has been completed, with phase II scheduled for completion at the end of this year.

The discovery is an important development in the worldwide effort to mimic the way plants make fuel from sunlight, a key step in creating a green energy economy. It was reported last week in Nature Materials by theorist Jens Norskov of the Department of Energy's SLAC National Accelerator Laboratory and Stanford University and a team of colleagues led by Ib Chorkendorff and Soren Dahl at the Technical University of Denmark (DTU).

Shropshire farmer Paul Parton could make more than £500,000 over the next 25 years by generating his own energy through solar PV panels installed on the roofs of his poultry units.Paul, who runs Parton’s Poulets in Market Drayton, is among the growing ranks of farmers nationwide finding new non-agricultural means of generating income in an increasingly competitive industry.

Từ việc vứt bỏ pin điện thoại bị chai một cách lãng phí, nhóm học sinh trường Lê Hồng Phong ( TP HCM) nảy ra ý tưởng tái sử dụng chúng thành chiếc đèn pin. Thiết bị gồm 6 đèn LED siêu sáng được bắt song song trên một bảng mạch rồi mắc nối tiếp qua điện trở và nối vào nguồn pin. Đèn được điều khiển bằng một công tắc 3 chấu gạt qua bên phải để bật đèn, còn đẩy qua phải là sạc. Thiết kế này nhằm tránh tình trạng vừa bật đèn vừa sạc làm pin hư hỏng hoàn toàn.

Philips Lighting is launching a new line of incandescent light bulbs designed to meet federal energy efficiency standards that will take force in the US over the next few years. While not as efficient as compact fluorescent or LED bulbs, EcoVantage bulbs will likely appeal to people who are unhappy with the quality of light delivered by the more energy efficient technologies.

The research team, led by Christian Wetzel, professor of physics and the Wellfleet Constellation Professor of Future Chips at Rensselaer, etched a nanoscale pattern at the interface between the LED's sapphire base and the layer of gallium nitride (GaN) that gives the LED its green color. Overall, the new technique results in green LEDs with significant enhancements in light extraction, internal efficiency, and light output.

Nhóm nghiên cứu, đứng đầu là giáo sư Christian Wetzel, giáo sư vật lý tại Rensselaer, đã tiến hành khắc axit một đường với kích thước nano trên bề mặt giữa phần đế bằng ngọc bích và lớp Gali nitơ (GaN) của đèn LED nhờ đó đèn có thể phát ra ánh sáng xanh. Nhìn chung, phương pháp mới này giúp tạo ra đèn LED xanh với hiệu suất và khả năng phát sáng tăng gấp nhiều lần.

VTD đã đầu tư một dây chuyền đóng gói đèn LED hiện đại với máy móc được đầu tư của Hà Lan và Đài Loan. Theo ông Dương Minh, Tổng giám đốc VTD cho biết: cuối tháng 5 sẽ giới thiệu sản phẩm đầu tiên ra thị trường. Hiện nay đơn vị đã có đơn hàng sản xuất trong bốn tháng

“Algae has been a hot topic of biofuel discussions recently, but no one has taken such a detailed look at how much America could make – and how much water and land it would require — until now,” said Mark Wigmosta, lead author and a PNNL hydrologist. “This research provides the groundwork and initial estimates needed to better inform renewable energy decisions.”

Chi phí ban đầu của đèn LED có thể khá cao, song xét về độ bền, tuổi thọ và khả năng tiết kiệm điện thì sử dụng đèn LED vẫn mang lại hiệu quả kinh tế cao hơn nhiều. Tuy nhiên nên chọn sản phẩm đèn LED của những hãng sản xuất có uy tín, cần lưu ý đến hiệu suất phát sáng cũng như tuổi thọ của nó. Thông thường, tuổi thọ của bóng đèn càng cao thì càng tốt.

Deputy Prime Minister confirmed this would be an important legal basis for investors to implement projects exploiting potential renewable energy sources, especially a series of wind power projects in the South Central Province, on islands and in remote areas. He also signaled the views and encouragement on increasing the promotion of renewable energy exploitation and utilization to meet the demand of national energy balance and sustainable development at present.

Currently, each day, Ninh Hoa Sugar Joint Stock Company processes 3,000 tons of sugar cane without using grid power. The entire electricity needs are met by the thermal electric unit with the capacity of 6 MW, the fuel for boiler is bagasse. From Dec 2010, the company installed one more bagasse generator with the capacity of 3 MW.

Senator Joe Lieberman called for a temporary halt on the building of nuclear plants in the U.S., and many news organizations have reported that it could cause a major setback for U.S. nuclear policy. Last year, the Department of Energy announced $8.3 billion in loan guarantees for the construction of two nuclear plants in Georgia. The plants are part of a major push by President Obama and Energy Secretary Steven Chu to support nuclear power in the United States.
