Clean green machine

SEPTA’s found a unique way to save energy, and therefore, money. The transit authority switched cleaning companies about 18 months ago to make sure all building housekeeping is done during the work day. By eliminating the need for lights after hours, the authority has found a way to save.

The Inquirer reports SEPTA has reduced its energy consumption by 12 percent thanks to various implementations like motion-activated lights. Between 2008 and 2009, $100,000 was saved in energy costs alone.
