The Warren County School System has cut energy costs for a fourth straight year, the savings like money in the bank for the schools which are able to use the funds on education rather than heating and cooling costs.Director of Schools Bobby Cox says the savings are like “a penny saved is a penny earned” when it comes putting the utility savings back into the school system.“We use the money we saved for educational purposes,” said Cox of the reduction in energy use for the 2015-16 school year which ran June to June. “This is the fourth year in a row we’ve been able to reduce costs for the year so that’s a good trend.”The savings during the recent year was significant. In the area of electrical costs, the school system saved $56,823 over the year before, its total electric bill coming to $1.31 million during 2015-16.
