Modifying human behavior saved the school system over $152,000 in electric bills last school year.“This is a gift to the taxpayers of Warren County,” said School Board member Bill Zechman of the savings seen during the 2011-12 school year. “It helps us in doing job No. 1, that being educating the children.”The savings – which specifically was $152,006 – came as the result of a system-wide initiative where school employees were challenged to modify their behavior when it came to saving energy.Director of Schools Bobby Cox noted the savings had to do with switching lights off when not in use and turning off other electronic items.Maintenance director Donnie Caldwell pointed out the savings amounts to close to 10 percent when compared to last year’s electric bill when the school system paid $1.86 million for energy compared to $1.71 million this year.
