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:

In addition to the new SunPower E19 Series product line, the company is also offering its current 18 percent efficiency or greater solar panels in the SunPower E18 Series product line. This family of panels includes 96-cell and 72-cell configurations, ranging from 305-watts to 225-watts.

“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.

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.

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.

Một khách sạn hạng sang tại thủ đô của Đan Mạch tự sản xuất điện bằng cách yêu cầu khách đạp vào những chiếc xe đạp được kết nối với máy phát điện. Mọi khách hàng tại khách sạn Crowne Plaza ở thủ đô Copenhangen của Đan Mạch sẽ được hưởng một bữa ăn trị giá 200 kroner (36 USD) nếu họ tạo ra 100 Wh điện.

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.

Designed with small capacity of 3-8kg per hour, the incinerator is suitable for small and medium businesses, hospitals or medical centers. It uses LPG gas (or DO oil) at the rate of 2,5kg of LPG per hour, uses 220V – 50Hz – single phase electric power.

According to Tien Giang Department of Industry and Trade, the operation of the two lamp posts which use wind and solar energy in Rach Mieu bridge and Hung Vuong bridge has been very good for the past four months. These lamps are working well and the energy they use is totally from natural and renewable sources.

Công ty thủy điện SDE Energy cho biết tới cuối tháng 4 này, công trình điện sóng biển công suất 10 GW của Trung Quốc sẽ được hoàn thành. Đây là dự án năng lượng biển đầu tiên ở Trung Quốc đạt công suất 10GW trên vùng ven biển.

With those practical figures and the supporting funds from the National Program, Ninh Binh Women’s Union has facilitated the construction of 530 biogas pits under the project.

the Hanoi Department of Industry and Trade headquarters, the department director Luu Tien Long, said the movement would become effective in 10 inner districts. 100,000 families will get involved and compete for the awards ‘Energy efficient families’ and ‘Exemplary energy efficient families’. The organizers expect the movement to be warmly welcomed by the community. Accordingly, the city leaders hope at least 300,000 Hanoi families will receive recognition by 2010.

Dự án BRESL với nỗ lực chung của Việt Nam và 5 nước châu Á gồm Trung Quốc, Indonesia, Pakistan, Bangladesh và Thái Lan hướng tới mục tiêu thông qua việc kết hợp đào tạo, chia sẻ kinh nghiệm, hợp tác kỹ thuật nhằm giải quyết rào cản hạn chế các Chính phủ trong việc áp dụng các tiêu chuẩn và nhãn hiệu suất năng lượng, thúc đẩy các doanh nghiệp sản xuất tham gia tích cực vào các chương trình dán nhãn, tạo một thị trường phát triển cho các sản phẩm và dịch vụ tiết kiệm năng lượng

In response to the government’s policy and the national program for energy efficiency, the An Giang Province Department of Industry and Trade together with the Philips Vietnam Company sent a team to rural areas in the province to launch the “The Path for the Goal of Power Saving” program for impoverished residents in the area.

Mr. Luu Tien Long also presented five public sector energy conservation projects: installing a public lighting system on Hanoi’s streets; building a rural lighting system in Hanoi’s Soc Son, Dong Anh and Tu Liem districts; replacing the lighting system at State offices; building a biogas power generation plant that uses waste from slaughter-houses, and building a biogas power generation plant using waste that is derived from fuels in Ba Vi district. Investment in these five projects is estimated to total nearly VND500 billion

Each year businesses added 2,000MW-3,000MW to the national power grid in the recent years, bringing Vietnam’s total power production to more than 18,400MW currently. In 2009, the country succeeded in dealing with power outages
