See solar energy hard at work in Springfield during the 10th annual Illinois Solar Tour, hosted by the Illinois Energy Association. The free, open-house-style event takes place on Saturday, Oct. 1, from 10 a.m. to 2 p.m., and enables attendees to take an up-close-and-personal look at the ways in which their residential and commercial neighbors are utilizing the sun’s energy to generate power and heat and save money on utility bills. The Springfield portion of the self-guided statewide tour includes commercial stops such as Maldaner’s Restaurant, The Kerasotes Building, API Solar and The Abraham Lincoln Unitarian Universalist Congregation. Residential stops include the Croteau residence, the Lopez residence, the Nguyen residence and more. For a full list of tour sites, visit http://illinoissolar.org or call 847-593-6070.
