I should have done this several days ago, but better late than never:
Check out Joel Makower’s excellent list of resources for businesses looking to save (or make) some money through energy efficiency. As he says:
Energy efficiency (the more business-like alternative to "conservation") has a strong foundation in a bottom-line-centric world. And there are rich resources — case studies, how-to manuals, calculators, incentive programs, technical assistance agencies, and more — to help companies manage the process. There’s also a sizeable industry that’s grown up around helping companies audit, assess, implement, and finance energy-efficiency solutions.
And yet, we’ve barely begun to harvest the low-hanging fruit, let alone sow the seeds of an economy that can continue to grow and prosper using continually less energy from oil and other polluting resources.
Get to it!
