By Steven Oberbeck, The Salt Lake Tribune -- The new 30-kilowatt solar energy system unveiled Monday on the roof of The Leonardo museum in downtown Salt Lake City is more than just a series of panels that will capture the sun's rays to produce electricity for the technology and art center once it opens in early October.

It also represents another big leap forward for Salt Lake City's ongoing effort to promote the development of at least 10 megawatts of renewable energy by 2015, said Vicki Bennett, director of the city's Department of Sustainability and Environment.
