EnergyHub, a home energy management company, recently announced that it will be supplying its technology to Honeywell for inclusion in the company's portfolio of energy management solutions. According to Joseph Puishys, Honeywell's president of Environmental and Combustion Controls, EnergyHub's home energy management system will allow homeowners to minimize their energy bills by viewing and adjusting their energy usage settings.

Students at MAST Academy recently compared energy consumption at the school between 2009 and 2010 for the August/Sept period. The total energy consumed by the school during the 2008-2009 school year from August through September was 3,228,120 KWH. This was reduced to 2,514,600 KWH during the year 2009-2010, a decrease of 22% of energy usage.

A star-rating system, similar to that used for electrical appliances, will now be a mandatory part of advertising for lease or sale of office space. The scheme is designed to make climate change a more important consideration in corporate decision-making, in part by naming and shaming companies with office space in energy-hungry buildings.

To meet customer needs and keep pace with the development of tourism and services, Dong Xuyen hotel has been constantly upgrading, improving and renovating facilities, and enhancing service style. Along with that development, the demand for electricity of the hotel is also increasing. Monthly average power consumption of the hotel is about 75 thousand kWh of electricity.

Now that would be a brutal blow for any industry battered by a vicious recession. But it's particularly bad news for the American wind industry, which had defied the downturn by installing a record 10,000 megawatts of new capacity in 2009. New wind capacity had grown an average 39 percent annually over the previous five years and represented 39 percent of all new electrical generation that came online last year.

Council wardens are getting on their bikes to improve efficiency and reduce the carbon footprint created by work vehicles. East Staffordshire Borough Council is adopting power assisted cycling to enable wardens to travel economically through the borough. Supplied by Lichfield-based electric bike specialist PowaStation, the electric bike enables staff to cover far greater distances than using a traditional cycle.

This technology has many advantages. Drying room is completely tight, therefore, seafood is isolated from fuel and is not spoiled. Especially, according to this technology, remaining heat can be withdrawn or adjusted based on different products through the heat supply equipment. Thus, apart from assuring product quality, drying seafood with steam reduces 10 times energy costs compared to traditional technologies.

South Korea is set to become home to a new $8.2bn offshore demonstration wind project, according to local media. The project, which is slated to be the largest in the Yellow Sea, will be used to test 20 turbines produced by local manufacturers in South Korea, its regional government has confirmed.

Dr. Nguyen The Hung from the Institute of Physics under the Vietnam Academy of Science and Technology has contributed to the efforts to realize the above objective by creating a type of power generator using natural light. In 2008, Dr. Nguyen The Hung and his colleagues began a research project aiming to manufacture a type of power generator system using solar energy according to the absorption diffusion principle (with natural light engine).

The Asian Development Bank (ADB) is optimistic that Asia can get the 10 trillion US dollars it needs to finance sustainable energy projects over the next 20 years. The projects will include more efficient use of coal and oil as well as greater reliance on renewable power sources such as wind and solar energy.

General Electric has created new halogen compact fluorescent light bulbs, GE Reveal and GE Energy Smart Soft, that unlike typical fluorescents (CFLs), contain less mercury (only 1 milligram) and don’t take time to warm up, being more efficient.

The European Hydrogen Association (EHA) and the European Regions and Municipalities Partnership for hydrogen and fuel cells (HyRaMP) have called for accelerated support from the EU, national and local governments to ensure a sustainable build-up of hydrogen infrastructure in Europe. Both organizations stress the need to integrate hydrogen infrastructure development into the EU’s current energy and transport infrastructure plans.

Nhà sản xuất Logitech (Mỹ) vừa chính thức trình làng bàn phím máy tính không dây, chạy bằng năng lượng mặt trời đầu tiên với tên gọi Logitech's K750 Wireless Solar Keyboard. Theo Engadget, Logitech's K750 sử dụng chuẩn QWERTY, và không hề sử dụng bất kỳ dây dẫn cũng như bộ sạc pin thông thường nào, mà chỉ cần bàn phím nhận được một chút ánh sáng ngoài trời là nó có thể hoạt động bình thường.

Regular innovation to improve productivity and product quality is the target that leaders of the company has always aimed at. With that target, in November 1998, the company invested in the mechanized blast furnace cement production line of China with the design capacity of 60,000 tons per year. In 2002, the company invested in an additional synchronous production line, increasing the total design capacity of the two lines to 120,000 tons per year. Currently, each year, the plant manufactures and supplies more than 300,000 tons of cement to the main markets in Hanoi and surrounding areas.

Making a cellphone battery last ten times longer is a first target for a large research project that IBM, Infineon and a number of European universities unveiled on Wednesday. The new research project, called Steeper, also aims to decrease the energy needs of other electronic devices like TV sets or supercomputers by 10 times when active, and to virtually eliminate power consumption when they are in standby mode.

A new clean tech company called Totempower Energy Systems Ltd. has come up with an easy way to put wind power within the grasp of everyday homeowners. The company is developing new micro-wind turbines that are designed for close quarters and non-disruptive installation, but the real key to getting more micro-wind turbines into consumers’ hands is the company’s “ease of ownership” plan which provides a soup-to-nuts service including site selection and connecting the turbine to the home electrical system.

Solar panels are usually mounted in series, to sum up their voltages, and the resulting power is sent to a large inverter, which transforms the DC voltage into AC. One big issue with this scheme is that if shade falls on one panel, or it gets dirty, the inverter lowers the current of all the other panels, and causing power losses through inefficiency.

MIT researchers are hopeful of capturing and releasing solar energy with the help of thermo-chemical technology. Scientists were already working on this technology in seventies but this project was aborted due to its expensiveness and termed as too impractical to achieve. But MIT researchers are now gearing up to take this thermo-chemical technology that is supposed to convert solar energy into electrical energy.

VietnamPlus and Siemens signed a partnership agreement in Hanoi on Oct. 21 whereby VietnamPlus will be the media sponsor for Siemens Green Technology Journalism Award 2010. This award is created for the first time in ASEAN in order to acknowledge and reward journalists for excellent reporting on energy efficiency, industrial productivity and sustainability issues. It is open to print and online media from Indonesia , Malaysia , the Philippines , Singapore , Thailand and Vietnam.
