India adding 2800 MW of wind capacity in 2015
ICRA expects wind energy capacity addition during the current fiscal year to grow 20{f24b02adee2102ff0c5f5079c50862fc8ba5fa53f8615b567037555463da2377} over the last year to about 2800 MW and will be driven both by the IPP and non-IPP segments. In the rating agency’s view, the demand drivers for the wind energy sector remain favourable in the long run. This is mainly aided by strong policy support in place at the Centre and in key states which have wind potential, favourable regulatory framework in the form of renewable purchase obligation (RPO) regulations, as well as the cost competitiveness of wind-based energy vis-à-vis conventional energy sources.National Institute of Wind Energy Launches Wind, Solar Online MapsThe National Institute of Wind Energy (NIWE), Chennai, India has launched two online maps, one each for…

X-rays reveal details of plastic solar cell production
Plastic solar cells are light, easy to install, and readily produced using a printer. Nevertheless, the processes that take place on the molecular scale during the production of organic solar cells are not yet entirely clear. Researchers have now managed to observe these processes in real time. Their findings could help to improve the efficiency of organic solar cells.
Making green fuels, no fossils required
Converting solar or wind into carbon-based ‘fossil’ fuels might seem anything but green, but when you start with carbon dioxide — which can be dragged out of the air — it’s as green as it gets. The technology that makes it economically feasible isn’t available yet, but a recently published paper presents nice step forward in the effort to not just sequester carbon dioxide, but turn it into a useful fuel that is part of a carbon-neutral future.

The Kymogen Wave Energy Generator
Energy Inventions | Hydro Power | Wave PowerMechanical Engineer David Hartmann and Craftsman Jason Ballash have designed a new wave power technology called the KymoGen, which has the potential to produce clean, low-cost energy using the constant power of waves. Key to the design is its simplicity. A portable 8’x8′ platform is tethered to a mooring on the sea floor. Inside the […]
Viaducts with wind turbines, the new renewable energy source
Wind turbines could be installed under some of the biggest bridges on the road network to produce electricity. So it is confirmed by calculations carried out by a European researchers team, that have taken a viaduct in the Canary Islands as a reference. This concept could be applied in heavily built-up territories or natural areas with new constructions limitations.

‘Yolks’ and ‘shells’ improve rechargeable batteries
One big problem faced by electrodes in rechargeable batteries, as they go through repeated cycles of charging and discharging, is that they must expand and shrink during each cycle — sometimes doubling in volume, and then shrinking back. This can lead to repeated shedding and reformation of its “skin” layer that consumes lithium irreversibly, degrading the battery’s performance over time. Now researchers have found a novel way around that problem: creating an electrode made of nanoparticles with a solid shell, and a “yolk” inside that can change size again and again without affecting the shell.
