The OneThing^TM Conservation Expo is based on the concept that Connecticut residents can conserve energy – and make a difference every day – by doing just “OneThing.’’ On October 10-12, 2008, the Connecticut Convention Center will be filled with a million “OneThings.” Touted as the “World’s Fair” of energy conservation, the Expo will give individuals, businesses and families a socially conscious “experience” that is stimulating and imaginative.
