Kill the Lights at the Department of Energy
(est. savings: $2.2 million)
Talk about irony. A June 2010 report from the Department of Energy's Inspector General showed that the department could save $2.2 million annually by adopting more efficient lighting systems, like installing occupancy sensors in rooms.
Stop Fed-Exing Empty Boxes
(est. savings: $350,000)
According to a Government Accountability Office report, the U.S. Department of Agriculture's Food Safety and Inspection Service sends its lab samples via Federal Express' next-day service. The empty sample containers are then Fed-Exed back, once again with next-day service, which costs roughly $15 round-trip. By returning containers via ground transport, the USDA could save an estimated $350,000 per year.
