obbing in the Atlantic, about nine miles from the sandy beaches of the Rockaway peninsula, a yellow buoy clangs and blinks, rising and dropping on the ocean swells. Fixed to the nose of the buoy are two anemometers that spin in the wind. They read the direction and speed of the wind 24 hours a day, like a dog with its head out the window of a car on an endless highway.

Cobalt Technologies this week said that it has made a breakthrough in producing biobutanol from beetle-killed lodgepole pine feedstock. Cobalt claims to be the first company to produce a drop-in replacement for petroleum and petrochemicals from beetle-affected lodgepole pine.

Bill Weihl, Google's green energy czar, said Thursday that's not the case. "We don't want to become an energy trader, or God forbid the next Enron," he said, when asked about the plans at the GreenNet conference in San Francisco. "What we want is the flexibility to manage our power contracts, and in particular be able to sign contracts that are useful to developers and that get more renewables on the grid."

The tower itself is 115 meters high -- the height of a 14-storey building -- and, bathed in intense white light, the overall effect resembles nothing so much as a religious object. Valerio Fernandez is director of operations for the PS10 platform and its neighbor, PS20.

A wave energy generator which was launched off the New South Wales south coast in March, has sunk in rough seas. The 170-tonne structure had been providing electricity to the grid from 150 metres offshore at Port Kembla. But it broke free from its pylons on Friday afternoon and sank on Saturday.

Apollo Solar Energy, Inc. (Apollo Solar), a refiner and producer of high purity tellurium (Te) and tellurium-based metals for the solar photovoltaic (PV) industry and specific segments of the electronic materials market worldwide, in the People's Republic of China, today announced that the Company has signed an agreement with the Ningguo Municipal Government to build a 2MW demo solar power station in Ningguo City

To learn energy situation at the whole group and find opportunities to save energy cost, Vinacomin conducted energy audits at its 32 affiliates, including 12 coal-pit and 5 open-cast extraction businesses, 2 sieving units, 6 mechanical engineering units and 2 transport enterprises. The survey results showed that coal-pit extraction facilities could save between six to 14.7 percent of total power consumption, averaging 10.7 percent. If energy efficient measures were taken, these coal-pit extraction units could save nearly 30 million KWh (equal to 3,000 tonnes of oil equivalent) or more than VND25 billion each year.

In April 2010, Hai Phong is distributed only 7.75 million kWh per day, while it will consume between 9-10 million kWh per day to meet all its demands. Unlike many provinces and cities which often have power cut in the hot dry season, Hai Phong is still light. Most people in the city don’t have to face power outage. This was because Hai Phong Electricity has creatively issued "quotas" for electricity.

But it's also one of the dirtiest with the world's 2,300 coal-fired power stations contributing around 40 percent of all man-made emissions, according to the World Coal Institute. Their continued use enrages many environmentalists who argue that we should be phasing coal out. But the coal industry is pinning its hopes on the rather oxymoronic-sounding "clean coal," which has become the umbrella term for a range of new technologies that share the aim of cleaning up coal in the 21st century. Earth's Frontiers takes a look at the options:

“This decade is crucial for effective policies to enable the development of solar electricity,” IEA Executive Director Nobuo Tanaka said. “Long-term oriented, predictable solar-specific incentives are needed to sustain early deployment and bring both technologies to competitiveness in the most suitable locations and times.”

You plug the appliances into the sensors, and the sensors into your home’s wall sockets. The sensors then relay each appliance’s electricity consumption to an Internet-connected router, via Zigbee, the RF standard crafted for appliances and other devices around the home. You can then view a graphical and numerical chart that shows how much that Vornado air purifier is costing.

Một loại tàu lặn hoạt động bằng bàn đạp có khả năng lặn sâu 30m đã được Công ty Marine Innovative Technologies Ltd (MIT) ở St.Petersburg, Nga, chế tạo. Tàu lặn này phần lớn được làm bằng kính acrylic đặc biệt giúp người ngồi bên trong ngắm cảnh dưới nước.

The heat of more than 38oC results in a sudden rise in electricity demand, and overloaded system. HCMC Power Company has been forced to implement an emergency power saving plan, part of which is to offer VND200,000 as reward for any households saving electricity by 6% in May and June.

The Second International Exhibition of Energy Efficiency and Environment Hanoi (ENTECH Hanoi 2010), a large exhibition of this kind for the north will be held from May 27-30 at the Giang Vo Exhibition Center in Hanoi.

With the success of those two projects, we have designed and manufactured the modular exhaust-heat-utilizing boiler with design pressure of 10kG/m2, working pressure of 6kG/m2, heat transfer surface area of the boiler 13,2 m2, the area of water heater 6,33 m2. All the designs have been registered at Vietnam Register.

Ông Huỳnh Kim Tước - GĐ Trung tâm Tiết kiệm năng lượng TPHCM (ECC) - cho rằng: "Nếu các công trình toà nhà, cao ốc tuân thủ quy định về thiết kế tiết kiệm năng lượng (TKNL) do Bộ Xây dựng ban hành thì đã có thể tiết kiệm được 20% năng lượng tiêu hao".

According to Ass. Prof, Dr. Sc., Nguyen Tac An, former Director of the Institute of Oceanography, Chairman of the Intergovernmental Oceanographic Commission, Vietnam has great potential to develop wave energy.

Featuring tropical monsoon climate, a high density of rivers and streams that are proportionally dispersed and comparatively sloping terrains Vietnam has great potential for the development of small and medium-range hydropower plants. Effective exploitation of this latent potential will not only create people extra income and meet the demand for energy in particular areas but also relieve the state energy deficiency.

Another popular and effective method to save energy in Ho Chi Minh City is using solar energy instead of electricity. Ho Chi Minh City authorities are providing every household with VND1 million to adopt solar energy.
