The Principal Solar Institute Documents Role of Solar To Power Organic, Local Food Production

Dallas, TX – December 4, 2012 -- Principal Solar, Inc (PSI; OTC Pink: PSWW), a publicly traded solar energy holding company executing a unique roll-up strategy to create the world's first distributed solar utility, today announced the release of "Energy Efficiency and Sustainability in Organic Food Supply." Authored by James W. Keyes, chairman, Key Development LLC, R. Michael Martin, executive vice president, Business Development, PSI, and Brett T. Gage, research assistant, the paper examines how alternative energy resources, such as photovoltaic (PV) solar, can enhance organic and local food production.


"In recent years, solar has become increasingly cost effective," says Keyes, advisor to Principal Solar. "Organic certification requires that foods be produced without genetic modification, synthetic hormones, unsustainable practices, or use of certain substances."

He adds that, of the various renewable energy alternatives available to fuel organic agriculture, PV solar systems are the most economical on the farm.
