Canada’s construction electricians will soon have an independent, third-party set of standards to help prepare them for work with solar PV projects. The Canadian Standards Association (CSA) has announced, in conjunction with the National Electrical Trade Council (NETCO), a certification program for construction electricians installing PV systems in (more…)
Researchers at the Massachusetts Institute of Technology (MIT) report that they have used carbon nanotubes to concentrate solar energy 100 times more efficiently than regular photovoltaic cells. The researchers, reporting in the journal Nature Materials, said that the nanotubes — hollow tubes of carbon atoms — could form antennas that effectively capture and focus light energy, (more…)
Homeowner’s associations, or HOAs, are – as we who have lived in them know – able to prevent residents from using a certain color of paint, or even hanging a certain kind of window covering in their homes. But defiance, should you put up a fight, can sometimes lead to an ongoing nightmare on the scale of Freddie Kruger, et al.
The Larry Lohrman Case (more…)
The California Department of Transportation, or Caltrans, announced last Wednesday that a solar power array is now online at a maintenance facility in Monterey. The 9.6-kilowatt system was designed and installed in July by local companies Earth Electric and Green Earth Engineering. It passed final inspections last week before the launch of renewable electricity (more…)
TD Canada Trust is doing what it can for Canada’s green economy. The bank recently commissioned a poll of Canadian house owners to determine Canadians’ awareness of and attitudes toward green energy. The survey, conducted at the end of July and into August, looked in particular at attitudes toward solar panels and found, among other things, that although a third of (more…)
Provincial Energy Minister, Brad Duguid, recently toured a hydroelectric project in Kapuskasing, Ontario to promote the province’s push for a greener and more sustainable economy. During his visit, Duguid stated, “I really think the Green Energy Act is good for the North,” referring to the provincial government’s legislation designed to bolster investment in a cleaner, (more…)
The National Renewable Energy Laboratory has confirmed results for a record-breaking conversion efficiency in solar cell technology. Oerlikon Solar and Corning Incorporated have combined technologies to produce a tandem solar cell using thin-film silicon. Oerlikon’s proprietary Micromorph® solar cells and Corning’s specialty, advanced light-capturing glass (more…)
