Some offices do not allow lights to be turned off at the end of the working day. And some offices have one light switch for multiple offices so if one person is out of the office then their light cannot be turned off or else everyone else's light is turned off as well. I propose that automatic motion sensor light switches be installed. This allows for lights to be turned off when no one is in the office and, at the same time, no one would have to remember to turn on/off the lights. Although the initial output would be expensive, the potential savings seem worth it and would offset the cost within a short time period.
