Alstom Renewable Power announced on 6 February 2013 the signature of a memorandum of understanding with Renova Energia, leader in wind power generation in Brazil, to supply, operate and maintain in Brazil around 440 onshore wind turbines for a total amount exceeding EUR 1 billion.
Chemists have manufactured a sheet that changes colour in the presence of water contaminated with mercury. The results can be seen with the naked eye but when photographing the membrane with a mobile phone the concentration of this extremely toxic metal can be quantified.
A new form of clean coal technology reached an important milestone recently, with the successful operation of a research-scale combustion system at Ohio State University. The technology is now ready for testing at a larger scale.
In the absence of policy action, China would account for 41% of global emissions in 2030 and developing countries 70%. Whatever weight were given to the requirements of historical responsibility and justice, effective global mitigation would require major and early reductions from business as usual emissions in China and other developing countries.
A unique alliance for German wind energy research was officially formed in Berlin yesterday - the Research Alliance for Wind Energy. Representatives of the three partners, the German Aerospace Centre (DLR), ForWind, the Center for Wind Energy Research of the Universities Oldenburg, Hannover and Bremen, and the Fraunhofer Institute for Wind Energy and Energy Systems Technology (IWES) signed the cooperation agreement.
There are great expectations for solar power, especially in the coming years, when the International Energy Agency projects solar to grow faster than any other renewable power. But what does science need to do to more fully respond to the opportunities ahead?
The 2.5-120 is the first wind turbine to bring together world-class efficiency and power output at low wind speed sites, capturing a 25 percent increase in efficiency and a 15 percent increase in power output compared to GE's current model.
Hydrogen has tremendous potential as an eco-friendly fuel, but it is expensive to produce. Now researchers at Princeton University and Rutgers University have moved a step closer to harnessing nature to produce hydrogen for us.
