A series of new, larger turbines with longer blades have been launched into the market recently as manufacturers strive to deliver the lowest cost of energy with the next generation of designs. London, UK A trend towards larger capacity turbines with longer blades and larger rotor diameters has been long established, with OEMs continuing to offer existing machines with a range of rotor diameters. But now, a new generation of still larger machines has been unveiled.

The idea is simple, says Kevin Moeller, PhD, and yet it has huge implications. All we are recommending is using photovoltaic cells (clean energy) to power electrochemical reactions (clean chemistry). Moeller is the first to admit this isn't new science. "But we hope to change the way people do this kind of chemistry by making a connection for them between two existing technologies," he says.

Scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have further boosted the energy conversion efficiency of flexible solar cells made of copper indium gallium (di)selenide (also known as CIGS) to a new world record of 18.7 percent -- a significant improvement over the previous record of 17.6 percent achieved by the same team in June 2010.

Two months on from the natural disasters that ravaged Japan’s infrastructure and economy, its government has said it is determined to plough forward with efforts in the field of sustainable development through trilateral cooperation. The country has committed to promote the use of renewable energy and energy efficiency to reach sustainable growth in the country as it rebuilds itself, officials said in a statement on Sunday.

Germany is coping without about three quarters of its nuclear power capacity by burning more climate-warming coal, reaping the rewards of renewables investments, and importing more French atomic energy. The shutdown over the weekend of another nuclear plant means almost 16 gigawatts of German nuclear power capacity was offline Monday, with nearly half of the capacity ordered to shut by the government in reaction to the Fukushima nuclear disaster in March.

Efficiency is a problem with today's solar panels; they only collect about 20 percent of available light. Now, a University of Missouri engineer has developed a flexible solar sheet that captures more than 90 percent of available light, and he plans to make prototypes available to consumers within the next five years.

More evidence that clear, strong policies are key to renewable energy development came recently via the American Wind Energy Association (AWEA). In a statement issued by the association, some statistics about wind energy growth in the country and the states that lead in wind energy development indicate that areas with strong policy are driving development at an impressive pace.

UN Secretary General Ban Ki-moon said on Tuesday that the accident at Japan's Fukushima nuclear plant suggested that there were large gaps in international systems to deal with safety breaches. Ban also announced a high-level international meeting on the issue in New York on September 22 during the UN General Assembly session.

The U.S. Postal Service – Office of Inspector General is to merge four of its data centres this month to save operating costs while increasing capacity and energy efficiency. The U.S. Postal Service – Office of Inspector General (USPS OIG) will house its consolidated data centres in one new state-of-the-art facility.

Leaked Intergovernmental Panel on Climate Change report predicts a 100 exajoule increase in renewable energy capacity. The United Nations is set to forecast substantial increases in the deployment of renewable energy through to 2050 as clean technologies such as wind and solar power improve and costs fall.

Cuộc thử nghiệm hệ thống cảm ứng lần đầu tiên do công ty HaloIPT phát triển đã khẳng định khả năng có thể nạp điện cho phương tiện khi đang di chuyển là rất lớn. Hệ thống nạp điện không dây này do HaloIPT, một công ty khởi nghiệp tại New Zealand, thiết kế và nhận được sự ủng hộ của tập đoàn tư vấn xây dựng quốc tế Arup. Hệ thống đã được giới thiệu tại Anh vào tháng 10 và có thể cho phép xe ô tô nạp điện khi đỗ trên một miếng đệm lót trên đường.

Hôm thứ ba vừa rồi, Tổng thư ký Liên Hiệp quốc, ông Ban Ki-moon phát biểu rằng tai nạn của nhà máy điện nguyên tử Fukushima của Nhật Bản đã cho thấy tồn tại những lỗ hổng lớn trong hệ thống quốc tế để đối phó với vấn đề an toàn hạt nhân. Ông Ban cũng thông báo một cuộc họp quốc tế cấp cao về vấn đề này tại New York vào ngày 22/9 trong khuôn khổ cuộc họp của Đại Hội đồng Liên hiệp quốc.

Facebook’s new, state-of-the-art data center is situated on 120 acres of land in Central Oregon. The campus will be completed in two phases, each consisting of 150,000 square feet of data warehousing space. Phase I has been completed, with phase II scheduled for completion at the end of this year.

Key findings from an upcoming climate change report released by the United Nations are expected to show that cost reductions in the renewable energy sector are likely to continue through to 2050, boosting their deployment.

During the workshop, Da Nang Department of Science and Technology focused on disseminating Law on Energy Efficiency and informing about the projects and programs of energy saving which were being implemented. The Department also introduced project "Energy Efficiency and Renewable Energy Applications in ​​Da Nang City in the Period from 2011 to 2015".

Shropshire farmer Paul Parton could make more than £500,000 over the next 25 years by generating his own energy through solar PV panels installed on the roofs of his poultry units.Paul, who runs Parton’s Poulets in Market Drayton, is among the growing ranks of farmers nationwide finding new non-agricultural means of generating income in an increasingly competitive industry.

The World Bank approved on earlier this week a new loan of US$330 million for Vietnam to support the mid-sized multipurpose Trung Son Hydropower Project (TSHPP) which will help meet growing domestic demand for electricity and bring flood control and irrigation benefits to rural and poor communities in Thanh Hoa Province.

ANU has a partnership with a Chinese manufacturer to commercialise new solar cell technology. The scarcity of high grade silicon is one of the things which pushes up the price of roof top solar panels. The majority of existing solar energy cells on the market rely on high grade silicon components.

Philips Lighting is launching a new line of incandescent light bulbs designed to meet federal energy efficiency standards that will take force in the US over the next few years. While not as efficient as compact fluorescent or LED bulbs, EcoVantage bulbs will likely appeal to people who are unhappy with the quality of light delivered by the more energy efficient technologies.

This marks Google's first clean energy project investment in Europe, the company said in a blog post, though it still requires formal approval from Germany regulators. Google is teaming up with German private equity company Capital Stage for the project, a firm that "brings strong experience in the German photovoltaic and renewable energy market," Google said.
