Western Kentucky University says it is challenging other Kentucky colleges and universities to see which can save the most electricity and water over a three-week period.
The Bowling Green school says the universities of Louisville and Kentucky, as well as Berea College, have accepted the challenge, which is called "Bluegrass Unplugged."
It is part of a national competition among colleges and universities aimed at reducing electricity and water use. The 2013 Campus Conservation Nationals allows schools to choose any three-week period from February to April to compete.
More than 200 schools nationwide are taking part.
"Bluegrass Unplugged" will run from March 23 to April 12.
