Gone are the days when green campus initiatives were a balm to the soul and a drain on the wallet. Today's environmental initiatives are all about saving lots of green--in every sense of the word. The environmental benefits of green campus projects--whether wind turbines or better insulation--are pretty clear. Unfortunately, in today's bleak budget landscape, everything must take a back seat to short-term fiscal reality. Can schools have their cake and eat it, too? Can environmental projects actually pad the bottom line? In short, yes. The return on investment (ROI) for wind and solar projects can vary widely, depending on local climate, electricity rates, and scale. At this point, the fast road to environmentally friendly savings is lined with more pedestrian pavers: The most cost-effective energy projects are those that do not produce energy at all, for example: (1) retrofitting buildings; (2) replacing lightbulbs; and (3) repairing HVAC systems.
