As we're faced with an increasingly large world population and ever-dwindling resources the race is on to produce cars that not only produce zero tailpipe emissions, but ones that are green to manufacture too.

Chicago là thành phố lớn thứ ba của Mỹ sau New York và Los Angeles, thuộc tiểu bang Illinois của miền Trung Tây nước Mỹ, ven bờ Tây Nam hồ Michigan. Được mệnh danh là “thành phố của gió”, thành phố đã phát triển mạnh nguồn năng lượng phong điện.

Chủ tịch Oilfox S.A Jorge Kaloustian đánh giá diesel sinh học chiết xuất từ tảo được coi như một sự lựa chọn hiệu quả để thay thế việc sản xuất từ dầu đậu tương và các loại dầu thực vật khác bởi vì không cần sử dụng đất nông nghiệp và tính năng khử đioxít cácbon thải ra từ các nhà máy công nghiệp.

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.

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.

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.

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.

The company has a thin film assembly line with an annual capacity of 40 MW. The company also has several manufacturing facilities around the country and exports solar panels to Germany, Italy in addition to setting up solar installations within the country.

"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.

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.

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.

Vanadium nitrogenase, một enzyme có trong rễ cây đậu nành, có thể là chìa khóa cho những chiếc ô tô vận hành bằng không khí trong một ngày không xa.

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.

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.
