The Coca-Cola company has been introducing more electric vehicles and other low-emissions trucks into its massive fleet, and now researchers at the Hong Kong Polytechnic University are developing yet another alternative energy option. The team has been working on a solar powered air conditioning system that would significantly reduce or eliminate beverage delivery truck emissions related to cooling.

The Abu Dhabi Distribution Company (ADDC), which supplies electricity to the city and surrounding areas, will have installed digital electricity meters in all buildings by the end of this year, its deputy managing director Abdulrahman al Dhaheri said yesterday. The new meters not only calculate power usage, but also allow consumers to sell their own solar-generated electricity back to the grid.

The United States is on the verge of a solar boom that could provide 4.3 percent of the nation's electricity by 2020, according to a new report from Bloomberg New Energy Finance. There's just a 12-figure catch: Investors need to put $100 billion into the solar industry to keep the generation of solar electricity growing by 42 percent a year for the next decade to expand capacity from the current 1.4 gigawatts to 44 gigawatts.

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 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.
