LA CROSSE, Wis. (WKBT) -

A simple change in technology is expected to save Gundersen Health System thousands of dollars a year.

The health system installed a program on most of its 9,000 monitors to turn them off after 15 minutes of inactivity. Until this they were on 24 hours a day.

"Computer monitors usually use about 40 watts of energy when they're on. When they're off, they use no energy. By turning off over, we'll say 7,000 computer monitors, we're going to save over $100,000 a year for this organization,” said Gundersen Engineering and Energy Manager Alan Eber.

The savings averages out to more than $14 per computer per year. Some computers that are used during procedures won't be turned off.
