Five Rare Earths Crucial for Clean Energy Seen in Short Supply

Limited supplies of five rare-earth minerals pose a threat to increasing use of clean-energy technologies such as wind turbines and solar panels, a U.S. Energy Department report found. The substances — dysprosium, terbium, europium, neodymium and yttrium — face potential shortages until 2015, according to the report, which reiterates concerns identified in a report a [...]

‘Intelligent’ Wind Turbines could Produce More, Break Down Less

Courtesy: greenbang.com Homeowners and Main Street businesses aren’t the only ones that could benefit from a more intelligent, sensor-monitored energy system. Smarter technology could also help wind-farm operators get more energy “bang for the buck” from their turbines, as well as save on maintenance and repair costs. That’s the goal behind a two-year research project [...]
