Solar Trackers


Solar tracking devices, mounted with photovoltaic (PV) panels, allow the panels to exactly track the sun's path across the sky and can increase the yield of solar energy installations by as much as 40 percent compared to stationary panels. Solar trackers have been around since about 1980, but their increasing use in both commercial-scale and residential solar energy projects is a direct result of proven, improved solar capture efficiencies.

Partnership creates Idea House

The local Sunday papers make for good reading sometimes. The Utah Salt Lake Tribune's feel-good story about a local Idea House has some great nuggets of information. Green jobs training at a local community college partnered with a Community Development Corp and the result: a foreclosed home refitted with green improvements, including insulation, greener appliances and a solar panel capable of generating all of its electricity - plus a class of electricians and technicians with new green job skills to add to their resumes.

The Green Pushback

by Deb Powers

The Green push back against mass renewable energy has begun - and it's challenging assumptions on many sides. Some folks have called it NIMBYism - but the NIMBY label is far too facile - and it's pre-loaded with negative associations that can be exploited to mow down opposition to plans as easily as the desire for a greener planet can be exploited to make existing energy companies and utilities lots and lots of money.
