This is the third day in a row that we are presenting the most efficient lighting systems invented recently. Now, it’s time for another invention from GE, who made a 1,500-lumen LED light bulb and cooled it through a technology used in aviation.

While Compact Fluorescent Bulbs have barely been seen in various parts of the world and incandescent lighting still rules in others, two Japanese companies already want to change them for LEDs – straight tube LED lamps, which, they say, are much more economical.

Weighing under 454 kilos (1,000 lbs), the Honda Air is run by a compressed air motor, with the energy held inside compressed air in pressurized tanks. It’s “programmed” to have an autonomy of around 100 miles and has a pneumatic regulator system.

Siemens has landed an order to supply 80 wind turbines for the Dan Tysk wind farm off Germany's North Sea coast. With a total capacity of 288 MW, the farm will begin supplying clean electricity to 500,000 German households in 2014. Dan Tysk Offshore Wind GmbH is owned by Vattenfall Europe with a 51 percent stake and Stadtwerke Munchen with a 49 percent stake.

A few days ago, the Israel-based energy company ZenithSolar has officially unveiled its 3rd generation Solar Z20. Being installed in Kibbutz Yavne in central Israel, the solar energy generator is a combined heat and power system, able to deliver 72% efficiency.

Tổng thống Nga Dmitry Medvedev đã đến Hà Nội hôm 30/10 để tham dự Hội nghị cấp cao Đông Á 17. “Trong số các thỏa thuận quan trọng nhất được ký kết giữa hai bên có một thỏa thuận liên chính phủ về việc hợp tác xây dựng một nhà máy điện hạt nhân ở Việt Nam”, ông Sergei Prikhodko phát biểu trước thềm chuyến bay sang Việt Nam của Tổng thống Medvedev.

Floating wind turbines are a little more complicated and require higher initial costs. But a new study, Project Deepwater, by the Energy Technologies Institute (ETI) in the UK has found that due to their greater ability to access stronger and more consistent winds deeper out at sea, they are more economically efficient in the long term.

It is not that unusual for offshore oil to develop offshore wind technology. The two share some of the same technical and engineering issues. Stat-Oil in Norway is also investing in offshore wind development, because many of the engineering solutions found to develop offshore oil, are also applicable to the development of offshore wind, like building platforms in deep sea.

According to Mazda Motor Corp, the new Mazda2 subcompact will have a fuel economy of 30 km/litre (70 mpg) and as the company said, it will become the world’s most fuel-efficient vehicle. Mazda2 is scheduled to be launched in Japan in the first half of 2011, being the first car fitted with SKYACTIV, a technology produced only by Mazda based on next-generation gasoline and diesel engines.

We’ve been talking a while ago about Michael Strano and his thin carbon nanotubes that can transform fuel poured onto them into electricity. A chemical reaction is set up by heating the nanotubes, triggering the transformation at a speed of 10 meters per second.

While disposal of sharps (used needles and syringes) at hospitals and other large healthcare facilities is highly regulated, medical waste disposal by the ten million people who self-inject at home for diabetes and other conditions is largely unregulated. The health risks and resulting economic costs of improper sharps disposal are immense, from needles and syringes washing up on beaches and possibly creating needlesticks, to needlestick injuries that can expose sanitation and other workers to infection risk.

The project is following up on a pre-feasibility study conducted by the Clinton Climate Initiative. Fluor’s task is to develop a conceptual master plan to be unveiled at the South African Solar Park Investors Conference (Oct. 28 and 29), which will be held in the Northern Cape Province.

Trong cuộc trao đổi với tờ The Gleaner, ông Nigel Logan, Giám đốc quản lí nhóm hoạt động tại PCJ nói rằng quyết định lắp đặt hệ thống đèn sử dụng năng lượng hiệu quả tại trường đại học Jamaica đã đáp ứng được yêu cầu của hiệu trưởng Ruel Reid khi ông đang tìm kiếm sự hỗ trợ trong việc giảm chi phí năng lượng ngày càng tăng cao tại trường.

Results from EECA's energy audit programme show that on average, companies can shave 20% off their energy use and costs - 10% at little or no cost and a further 10% with a simple payback of less than five years. Typically, for every dollar invested in an energy audit, $7.50 of energy savings are identified.

Leave it to larger-than-life Texas to lead the U.S. into a new energy future. While the state is most closely associated with oil, it has also been an early pioneer of wind power, and is beginning to embrace solar energy along with armloads of new green jobs. Now the San Antonio Water System has set the national bar high in the sewage-to-biogas field, by becoming the first water district to hook a biogas facility up to a commercial gas pipeline.

First announced in 2006, the facility represents an investment commitment of $1 billion and opens up extensive new opportunities for economic development in Vietnam. The facility is the largest assembly and test factory in Intel’s global manufacturing network, with a total area of 46,000 square meters, equal to the size of 5 ½ football fields. Production commenced in the middle of this year, starting with production of chipsets for laptops and mobile devices for Intel customers worldwide.

With the second largest tidal range in the world, about 50 feet, the Severn estuary has been eyed for years as a potential energy source, particularly as the appetite for sustainable energy sources has been growing over the last few years. The U.K. has pledged to have 40 percent of its electricity generated from renewable sources by 2020 to meet European Union requirements.

At three feet (11 meters) tall, the SunCatcher is almost four times bigger than the world’s largest biological flower, the Sumatran titan arum. It has parabolic petals that appear virtually flat, like those of a buttercup. The device is made up of 40 mirrors, tightly arranged into a 3,400-square-foot (315-square-meter) dish that, like a real flower, angles toward the sun.

Báo cáo Năng lượng gió toàn cầu 2010 (GWEO 2010) chỉ ra lượng gió có vai trò then chốt trong việc đáp ứng đủ nhu cầu năng lượng thế giới ngày một tăng cao và tiến tới mục tiêu giảm đáng kể lượng phát thải khí nhà kính. Theo dự tính, tới năm 2010, công suất điện từ năng lượng gió sẽ đạt 1000 GW, giúp giảm 1,5 tỉ tấn CO2 mỗi năm, chiếm 50 – 75% tổng mức độ giảm thiểu phát thải khí mà các nước công nghiệp hóa đã thông qua tại cam kết Copenhagen tới năm 2020. năm 2030, sẽ có khoảng 34 tỉ tấn CO2 được cắt giảm nhờ công suất 2300GW điện từ phong năng.

Vietnam wants to further promote cooperation with Japan, the country’s top partner, in the spirit of strategic partnership for mutual benefit, said Prime Minister Nguyen Tan Dung. At a reception for former Japanese Prime Minister Yukio Hatoyama and the Japanese parliamentarian delegation in Hanoi on Oct. 25, PM Dung suggested that both countries should join efforts to expand trade and investment to match with their potential.
