The Ministry of Trade, Industry and Energy of Korea has fully launched an energy efficiency rating system for electric vehicles, categorizing 278 models into five levels.

Công nghệ được phát triển bởi nhà điều hành mạng lưới điện khu vực Tây Bắc nước Anh với tên gọi là CLASS, giúp Nhà điều hành Hệ thống Điện lưới Quốc gia (ESO) giải quyết ổn định nhu cầu và nguồn cung cấp điện tăng đột biến trên khắp Vương quốc Anh.

For African students living in remote, off-the-grid locations, learning about computers and digital technology is virtually impossible. But what if the digital world were brought to them?

In recent years, with the efforts of the Can Tho City Electricity Company and the related authorities, the communication, and implementation of practical power-saving models have been well performed. Then, the power saving policy of the State has really come to life of all classes of people in the Can Tho city with positive responses.

The MOU will enable a comprehensive education in energy efficiency technology and management, complementing classroom teaching and demonstrating the real-world application of energy efficiency.

The American Council for an Energy-Efficient Economy (ACEEE) published the 2015 edition of its biennial City Energy Efficiency Scorecard today, ranking U.S. cities based on their local energy policies and initiatives. And for the second time in a row, Boston is top of the class.

Với công nghệ nén khí thế hệ mới theo tiêu chuẩn ISO 8573-1 CLASS 0 (2010), người ta không còn cần đến dầu để sản xuất nhôm, nhờ đó tiết kiệm được 100% chi phí năng lượng, đảm bảo không gây ô nhiễm và giảm nguy cơ hoả hoạn.

This could be a classic win-win solution: A system proposed by researchers recycles materials from discarded car batteries -- a potential source of lead pollution -- into new, long-lasting solar panels that provide emissions-free power.

The tolling of the evening bell signals the end of the day’s classes at Donyo Wasin primary school. For a few adept pupils like Sotik Leleno, however, it ushers in the time for their private studies under the glow of solar powered lighting.

Morocco said Tuesday it is "very confident" of finding the investment needed to build vast solar power plants in its southern desert regions and become a world-class solar energy producer.

Aaron Sebens and his class of fourth-graders from the Central Park School for Children in Durham, North Carolina hit Kickstarter back in March to try and raise enough money for their classroom to go off-grid.

Scientists at the Centre for Solar Energy and Hydrogen Research Baden-Württemberg, ZSW (Germany) have developed top-class lithium-ion batteries.

Researchers from the Vienna University of Technology, together with colleagues from the U.S.

An insight into the properties of fullerene is set to open the door to a new class of electronic acceptors which can be used to build better and cheaper organic solar cells.

CyberSmart Africa implements a practical and scalable solution to enlighten the frequently ignored rural schools with contemporary education. Funded by the United States Agency for International Development (USAID), CyberSmart’s “tech-lite” approach, which includes a specially adapted interactive whiteboard and other low-power digital tools, puts learning first. The system uniquely focuses on teacher training and puts the latest low-power, portable equipment to work directly in the classrooms of off-the-grid rural schools.

Only to the visually-impaired it may look like fuel cells and electric cars don’t enjoy success nowadays. Daimler AG has just started a pilot program of leasing Mercedes-Benz hydrogen fuel cell cars to 5 to 15 users in the US, to see how their car acts in real life conditions and how people receive them. To me this looks like a postpone of the real thing, just like GM did to EV1.

"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."

In H.G. Wells’s The War of the Worlds, tiny organisms found in nature save the world from powerful high tech invaders that have overwhelmed mankind’s powerful high tech weapons, and in a classic case of life imitating art, there they go again.
