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.

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.

The Hi-tech Park in District 9, Ho Chi Minh city has examined, accepted and put into use 28 wind-and-solar lamp posts installed by Kim Dinh JSC International Group and The Public Lighting Company of Ho Chi Minh city.

ENTECH HANOI 2010 từ 27-30/5/2010 tại Hà Nội với chủ đề “Hiệu quả Năng lượng – môi trường, hiệu quả kinh doanh, phát triển bền vững”. Đây là cơ hội để cộng đồng doanh nghiệp Hà Nội, doanh nghiệp trong và ngoài nước quảng bá các trang thiết bị và công nghệ tiết kiệm năng lượng; công nghệ sản xuất sạch hơn và công nghệ môi trường.

In Hanoi alone, the survey results in 10 big businesses active in major economic sectors such as textile-garment, leather and footwear, mechanical engineering, electrical and electronics etc. showed that these businesses could save 3.2 million kWh, or VND40 billion, each year if they took energy efficient measures.

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.

According to Nguyen Trong Thu, the secretary general of the Bat Trang Ceramics Association, there used to be about 700 traditional coal kilns that were in continuous operation, which caused serious environment pollution.
