Đèn LED là một trong những hướng phát triển quan trọng ở lĩnh vực tiết kiệm năng lượng cho chiếu sáng của nhiều quốc gia.

“This increase in module efficiency, coupled with our thin-film technology’s real-world yield advantage when compared to crystalline silicon PV, results in higher energy density and lower levelized cost of energy (LCOE).”

Ngày 7-12, tại TP Quy Nhơn, Hội Chiếu sáng Việt Nam phối hợp với UBND TP Quy Nhơn đã tổ chức Hội thảo khoa học chiếu sáng toàn quốc năm 2012

In a move that could put wind energy on equal economic footing with traditional fossil fuels, GE (NYSE: GE), Virginia Polytechnic Institute & State University (Virginia Tech), and the National Renewable Energy Laboratory (NREL), will begin work on a project that could fundamentally change the way wind blades are designed, manufactured and installed.

Rice University scientists have unveiled a revolutionary new technology that uses nanoparticles to convert solar energy directly into steam.

Embattled photovoltaic solar power manufacturer Amonix announced on Tuesday that it has broken the solar module efficiency record, becoming the first manufacturer to convert more than a third of incoming light energy into electricity – a goal once branded "one third of a sun" in a Department of Energy initiative. The Amonix module clocked an efficiency rating of 33.5 percent.

Another German industrial giant has bailed out of the Desertec project, which is trying to safeguard the future of a green Europe with expanded use of renewable energy. Bosch has confirmed that it will no longer be a member of Desertec by the end of this year.

Germany installed nearly 1,000 MW (1 GW) of new solar power in September, bringing its total for the year up to 6,200 MW (6.22 GW). These statistics were provided by the German Federal Network Agency, The Bundesnetzagentur (or BNetzA). The solar industry there also saw solar generation growth of over 50% in the first 9 months of 2012.

Declining PV prices, incentives, and the fear of losing incentives have caused a surge in solar installations in Australia. The result has been that the country has reached 2,000 MW of installed solar PV.

Đèn LED có hiệu suất phát sáng cao, nhiều màu sắc đẹp, tiết kiệm điện năng, tuổi thọ cao đồng thời chịu được nắng mưa, va đập nhẹ đang được nhiều người tiêu dùng ưa chuộng.

No form of renewable energy has gained more ground in the past 15 years than wind, with installed capacity up 40-fold. Now, facing a long list of hurdles, the Global Wind Energy Council says the industry will need to work hard to make the next 15 years as fruitful – a necessity in the fight against climate change, in its view.

Hiện trên thị trường đang phổ biến rất nhiều loại bóng đèn như: Đèn huỳnh quang, đèn compact, đèn LED, đèn sợi đốt, đèn chùm, đèn trang trí… Vậy nên chọn loại bóng đèn nào để vừa đảm bảo an toàn, vừa tiết kiệm điện lại phù hợp với mục đích sử dụng.

Europe's installed wind power capacity has reached the landmark 100 gigawatt level even as doubts about the industry's future growth potential persist.

Long gone are the days where the only place LEDs were useful was the backlighting of a $10 wristwatch. LED technology has come a long way in the past 5 years from being an extremely niche technology to becoming a well-established force in the mainstream lighting market.

Located in the tropics, Vietnam still cannot take full advantage of its sun and wind resources to generate electricity. This has been attributed to the unreasonable mechanism which is unattractive to investors.

Vietnam and Denmark have pledged to work hand-in-hand on the advancement of indoor energies, under an agreement signed on November 7 in Hanoi.

s green building a trend in major global sporting events? It certainly was at the London Olympics, which saw all of its permanent structures built to green standards, and materials from all of its temporary buildings recycled or reused upon deconstruction.

Vietnam Energy Association Chairman Tran Viet Ngai has said that Vietnam's energy efficient product market has plenty of room for investors due to limited product categories. At current, only a few such as compact and LED lamps are being produced.

Việt Nam nằm trong khu vực có cường độ bức xạ mặt trời tương đối cao, nhiều nhất phải kể đến TP.Hồ Chí Minh, tiếp đến là các vùng Tây Bắc (Lai Châu, Sơn La, Lào Cai)…

Các nhà khoa học Hàn Quốc đã mô phỏng cấu trúc phát sáng ở bụng dưới của đom đóm để cải tiến thấu kính của đèn LED nhằm hạ giá thành
