BIOPAC Systems, Inc. crossed a milestone with its solar power—the company has generated more than 117,500 kilowatt hours (KWH) and saved 145,735 pounds of CO2 emissions since installing solar roof tiles in January 2007.

Solar power covers 35-50% of the company's power needs, depending on the season. In addition to solar roof tiles, the company uses motion sensor lights, energy efficient bulbs, and a computer-controlled central air conditioning system. Flexible work schedules and seamless integration of offsite workers also help reduce peak impact hours.
