Hôm thứ ba vừa rồi, bộ trưởng Bộ Năng lượng Hoa Kỳ, ông Steven Chu đã thông báo khoản hỗ trợ mới trị giá 5 triệu USD cho những nỗ lực cộng đồng để triển khai cơ sở hạ tầng xe điện và các trạm nạp điện.

The research team, led by Christian Wetzel, professor of physics and the Wellfleet Constellation Professor of Future Chips at Rensselaer, etched a nanoscale pattern at the interface between the LED's sapphire base and the layer of gallium nitride (GaN) that gives the LED its green color. Overall, the new technique results in green LEDs with significant enhancements in light extraction, internal efficiency, and light output.

Máy bay năng lượng mặt trời (Solar impulse) nổi tiếng của Thụy Sĩ và duy nhất trên thế giới đã sẵn sàng cho chuyến bay quốc tế đầu tiên tới thủ đô Brussels của Bỉ. Dự kiến chuyến bay này sẽ diễn ra vào ngày 2/5, nếu điều kiện thời tiết tốt.

Xuong Giang paper mill under Bac Giang Import Export Corporation-IMEXCO Bac Giang is the largest energy consumer in the province of Bac Giang. Responding to the energy saving program in recent years, the factory has continuously made improvements to reduce power consumption and protect the environment. However, according to experts of Hanoi Center Energy Conservation Center, energy saving potential in this business is still quite large.

Along with the pressure of raising electricity prices, fuel prices, adjusting the VND/USD exchange rate, price of coal sold to cement households has risen by 40% since the beginning of April, which has added a greater burden to cement enterprises. According to Mr. Nguyen Van Thien, Chairman of Vietnam Cement Association, currently, the total energy costs account for 45% - 50% of cement production costs. An 18% increase in gasoline price, a 15.3% increase in electricity price and a 40% increase in coal price have made price of cement increase by 10% to 15%.

Australian prime minister Julia Gillard today announced the approval of a $104.7 million project to integrate solar energy into one of Queensland’s largest fossil fuel power stations. The 750 megawatt (MW) coal-fired Kogan Creek Power Station in South West Queensland will be integrated with a new 44 MW solar thermal system, making it the largest project of its kind in the world.

Các nhà nghiên cứu tại Đại học Hebrew, ở Jerusalem, Israel, đã đạt được bước đột phá trong lĩnh vực nghiên cứu khoa học nano, họ đã thành công trong việc làm thay đổi tính chất tinh thể nano với các nguyên tử tạp chất, thông qua một quá trình được gọi là doping. Điều này đã mở đường cho việc sản xuất các tinh thể nano bán dẫn đã được tăng cường tính năng dẫn điện

Edano said, ‘We will create eco-towns that are fully equipped with district heating utilising plant matter and biomass from the region and cultivate features of communities that thoroughly foster public welfare. We will proceed by moving forward with the world’s most advanced reconstruction plan, with a vision of going beyond mere restoration to the previous state and instead create a truly marvelous Tohoku region and indeed a marvelous Japan.’

“Algae has been a hot topic of biofuel discussions recently, but no one has taken such a detailed look at how much America could make – and how much water and land it would require — until now,” said Mark Wigmosta, lead author and a PNNL hydrologist. “This research provides the groundwork and initial estimates needed to better inform renewable energy decisions.”

In recent times, Gia Lai Power Company has taken many measures in propagating the economic and effective use of electricity, thus saving not only an energy source for the country but also expenses for agencies, businesses and households. Thereby Gia Lai Power Company has made a good use of the electric energy source allocated for production and social-economic development in the province, contributing significantly to the electric energy saving movement.

100% of the barracks and households in Truong Sa District (The Spratly - Khanh Hoa Province) can now use electric energy for their work and life, with the continuous supply for 24 hours a day. The whole district is now under television and telephone coverages. It is special that all the electric energy used in this island district is produced from wind power and solar energy. So far, Truong Sa has been the first district in the country to use clean energy sources.

Sa Giang Import Export JSC (Sa Dec Industrial Zone, Dong Thap) is specialized in producing shrimp chips which have been very familiar to domestic consumers. Since late 2010, as part of the project "Promoting energy conservation in small and medium enterprises", the company has implemented energy audit for the purpose of raising the efficiency of energy use.

Công ty TNHH Tân Thế Kỷ - Hà Nội) đã đầu tư kinh phí để thay đổi công nghệ nhằm giảm tiêu hao nhiên liệu. Bà Nguyễn Thanh Giang phó Giám đốc công ty cho biết: "Công ty đã đầu tư hơn 100 triệu USD nhập thiết bị hiện đại, tiết kiệm điện. Trong khi đó, Công ty Cổ phần Đại Đồng Tiến cho hay, đối phó với giá nguyên vật liệu đầu vào tăng, công ty vừa đầu tư một dây chuyền hiện đại trên để hạn chế tiêu hao năng lượng, cũng như tiết kiệm nguyên vật liệu.

Deputy Prime Minister confirmed this would be an important legal basis for investors to implement projects exploiting potential renewable energy sources, especially a series of wind power projects in the South Central Province, on islands and in remote areas.
