Louisville businesses and schools are entering a competition to increase their building’s energy efficiency. It’s called Kilowatt Crackdown. All 150 Jefferson County Public Schools are in the competition, and about thirty businesses have joined so far.Leslie Cook with the EPA’s EnergySTAR program says Louisville is leading the way with this initiative."We really see this effort in Louisville as a national model to promote and show a real world example of how this community has come together to really get serious about protecting the environment and get serious about fiscal responsibilities and their energy costs," says Cook.Businesses can still join the competition through next Friday. The Louisville Energy Alliance says businesses can save up to ten-percent off their energy bill per month through the program.
