I believe a great way the government could save energy and money would be to put in motion sensored lights. This would work especially well in restrooms, hallways and administrative offices. We would no longer have to rely on employees to turn the lights off. As long is someone is in the office working, in the restroom or walking down a hallway the lights are on. When you exit the area the lights go off. A great way to save energy and reduce costs at the same time.
