Wind energy cuts the electricity bill

September 3, 2014 4:08 pm | by EurekAlert! | Comments

The UPV/EHU study analyses the electricity market in Spain during the 2008-2012 period -a time of maximum renewable penetration in Spain when energy production within the Special Scheme saw a 57% increase- and quantifies its cost. To do this, they firstly measured the market savings....

Live from inside a battery

September 3, 2014 4:04 pm | by EurekAlert! | Comments

Mobile phones, digital cameras, camcorders, notebooks: They all run on lithium-ion batteries. These are characterized by high energy densities while remaining small and light enough to be used in portable devices. "A lithium-ion battery can store three to four times the energy....

September 3, 2014 4:02 pm | by EurekAlert! | Comments

Botnet. A term from the world of computers is gradually tiptoeing its way into the world of building automation. You have to anticipate this kind of attack scenario, according to Dr. Steffen Wendzel of the Fraunhofer Institute for Communications, Information Processing and Ergonomics FKIE in Bonn....

A fix to our cell-phone waste problem?

September 3, 2014 3:58 pm | by EurekAlert! | Comments

When it comes to cell phones, the world is stunningly wasteful. Customers will buy more than 1.8 billion new ones by the end of this year only to abandon almost half of them to drawers, and they'll recycle a mere 3 percent of them. But creative and enterprising efforts are underway....

Breakthrough for carbon nanotube solar cells

September 3, 2014 3:55 pm | by EurekAlert! | Comments

Lighter, more flexible, and cheaper than conventional solar-cell materials, carbon nanotubes (CNTs) have long shown promise for photovoltaics. But research stalled when CNTs proved to be inefficient, converting far less sunlight into power than other methods....
