Global Forest Watch: The Loss of US & Canadian Forests

By Roy L Hales

Screen shot 2014-03-18 at 3.43.47 PMThere have been 150,000 visits to the Global Forest Watch website since it went online Thursday and for good reason. The interactive map is an an  online forest monitoring system, created by the World Resources Institute and more than 40 partners, that allows you to examine changes in the forest cover anywhere in the World. They drew upon many databases, including Google Maps , data from the University of Maryland and satellite imagery. Global Forest Watch has already shown that the World lost 2.3 million kilometres of tree covering between 2000 and 2012. My concerns were more specific, I wanted to know if the forests in Canada and the US are presently emitting, or storing, carbon.

New Lux Research Report Predicts a Comeback for Concentrated Solar Power

By Roy L Hales

Screen shot 2014-03-18 at 3.43.47 PMIn 2010 concentrating solar power (CSP) projects like Ivanpah were heralded as the future of utility scale solar projects. Spain and the US led the World in the development of this technology. Since then, they have since largely fallen to the wayside in the wake of inexpensive  photovoltaics (PV) and presently survive in niche applications. The average CSP system costs 37% to 60% more than a comparable PV system. A new report from Lux Research predicts this will continue until CSP providers develop components that operate at high temperatures, integrate low-cost thermal energy storage (TES), reduce materials and maintain system performance.
