With a stalled Green energy movement that seems to have convinced few people that it can actually replace our dependence on fossil fuels, Tom Rand thinks it's time to move the goal posts. An engineer who is also a venture capitalist who puts his money where his mouth is, his challenge is simple: America can either pioneer green energy as an investment that will pay off for centuries to come, or wind up paying someone else for the same solutions down the road.

A team of Ukranian and American scientists have discovered that by using structures called ferroelectric nanowires, they can generate electricity from a temperature difference. This concept is now new, but rather uses different approaches and materials. It can harvest energy by using the temperature difference between materials and/or ambients.

Adobe, the software giant, has installed 12 100-kilowatt solid oxide fuel cells, or Energy Servers, from Bloom Energy at the Adobe headquarters. The cumulative 1.2 megawatts of power that the fuel cells generate will provide Adobe with about one-third of the power it needs to run the building.

Apart from awareness in all the company, LaVie has also decided to invest in new technology as a way to reduce energy consumption. The deputy general director reveals that her company will replace all energy-consuming air compressors by smaller ones that fit the capacities of the current production lines. In addition, it has changed its lighting systems to LED lamps, and reduced water use as a way to cut energy consumption as well.

The two researchers tried to combine spintronics (electronics that use the spin of electrons to read/write data) with thermoelectricity, which transforms heat into electricity through the Seebeck effect. The spin-Seebeck effect (the conversion of heat to spin polarization) had been observed in action in 2008, but only on a metal rod, not on a semiconductor. They called their new heat-to-electron spin discovery “thermo-spintronics.”

The UK environmental group Carbon Trust and Cambridge University’s Cavendish Laboratory have jointly formed a new company called Eight19 concentrating on the development of new organic photovoltaic (PV) technology that could make the installation of solar cells cheaper and easier.

As part of the National program on energy efficiency and conservation, Energy Efficiency Office has collaborated with the German Energy Agency, ALTUS AG Company of German and Hanoi University of Science and Technology’s Center of New Energy to start the project "Installation of grid-connected solar system at the headquarters of MOIT to save energy and protect the environment".

We all know LED as being the flagship of green lighting, but what if those so-called “efficient” LEDs turned out to be even more energy-effective under certain conditions? The Kyoto University, in collaboration with Stanley Electric Co Ltd found a way to increase the emission intensity of silicon-based thin films by several times.

Authorities have pledged to speed up construction of green buildings in response to the surge in building energy consumption that has resulted from the country's rapid urbanization. Li Bingren, chief economist at the Ministry of Housing and Urban-Rural Development (MHURD), said at a press conference Monday that authorities had made numerous efforts to save energy and reduce emissions, yet energy use efficiency remains low.

The thing on the left is a snail, and it’s called abalone. Aside the fact that it’s edible, the abalone taught Angela Belcher, from MIT, how to turn carbon dioxide into rock-solid construction materials and thus sequester the gas for hundreds of thousands of years, instead of burying it underground, which is not as safe and as useful.

Chúng ta đều biết đèn LED dẫn đầu về hiệu quả của việc chiếu sáng. Trong những điều kiện cụ thể, liệu đèn LED có thể đem đến hiệu quả lớn hơn? Các nhà nghiên cứu thuộc đại học Kyoto đã hợp tác với Công ty Stanley Electric để tìm ra cách tăng cường độ phát sáng của tấm bán dẫn silicon trong đèn LED thêm vài lần nữa.

Energy supplier EDF have unveiled a new gadget that allows consumers to turn off their appliances from anywhere in the home. The wireless EcoManager enables householders to control and switch off their microwave ovens, TVs and stereos from any location, allowing them to cut needless energy use and save money on their bills in the process.

Bắt đầu được đưa vào chiếu sáng thử nghiệm bằng đèn Led từ 2.9, đến nay hệ thống chiếu sáng khu vực Hồ Thiền Quang đã thực sự phát huy tác dụng, đem lại hiệu quả nhất định và được sự đón nhận của đông đảo người dân.

Một người Anh đã lập nên một thư viện đặc biệt chuyên cho mượn thiết bị tiết kiệm năng lượng. Ông tên là Barrie Mould, thành viên dự án Transition Ashtead (Anh) - chuyên tư vấn và khuyến khích việc cắt giảm tiêu thụ năng lượng. “Thư viện” của ông hiện có khoảng 35 loại bóng đèn tiết kiệm điện, từ đèn huỳnh quang đến đèn LED. Các bóng đèn có đủ kiểu dáng, kích cỡ, công suất.

The 27-nation bloc could make 90 billion liters (24 billion gallons) of so-called next-generation ethanol in 2020, about 65 percent of predicted fossil gasoline use, the London-based group said in a study. At least 100 refineries a year could be built in the bloc from 2013, it said. The EU currently has no commercial factories that refine biofuels from plant waste.

A new directly solar powered air conditioning system has been unveiled in China that has the potential to not only make cooling a home green, but also save homeowners a huge amount of money at the same time. The machine is made by a company called Vicot.

A report published by an Indian Defense ministry-backed think tank has proposed for the establishment of an international space-based solar energy program with India and the United States initiating this massive project. The report is prepared by Peter Garretson, a US Air Force lieutenant colonel, working with the Institue of Defense Studies and Analyses, New Delhi. The reports calls for the Indian and the United States’ governments to extend their strategic partnerships to initiate this pathbreaking project and make the space-based solar energy a commercially viable business venture by 2025.

On September 8, 2010, at the headquarters of the Ministry of Industry and Trade, the Energy Conservation Office organized a ceremony to present an energy label titled Vietnam Energy Star and hand over energy efficiency certifications to three compact lamp manufacturers: Dien Quang, Philips Vietnam and Rang Dong.

In earlier September, in Dong Thap, representatives of the Center for Industrial Promotion & Consultancy Development reported and discussed the results of energy audit for businesses in the province. This is the program following the national energy policy which has been supported by the Ministry of Industry and Trade in some Southern provinces and cities (called ANEP 2).

The project entitled, “Studying, Designing and Manufacturing Large-Diameter, Non-Rotary Pipe-Connection Automatic Welding Equipment Systems” was checked and accepted on September 11 in Hanoi. Dr Hoang Van Chau from the National Research Institute of Mechanical Engineering is the director of the project with the technology for manufacture of pressure pipelines for small and medium-sized hydropower projects.
