It's another feather in SUNY ESF's "green" cap, as one more portion of the campus switches over to solar power. On a chilly Friday morning that reminds us all where we live, the switch was thrown on another chunk of solar panels at the College of Environmental Science and Forestry. This latest 23-kilowatt system is mounted on the side of Baker Laboratory and is part of an overall $29 million rehabilitation project using the latest in green construction practices. This past summer the first photo-voltaic array, a 15-kilowatt system, was installed on the roof of nearby Walters Hall. The flat panels are maintenance-free once installed and do not need full sum to operate efficiently. The 2 systems combine with a fuel cell to provide 20 per cent of campus power needs. It's more than smart business practice at this college. President Neil Murphy says the green technology market is worth about a trillion dollars a year. "It's increasing at a rate of 25 per cent a year," Murphy said. "And so it's important to the institution from an educational standpoint, to meet the needs of that industry, but also to reflect that industry in our practices to the local community," Murphy said. Next on ESF's agenda, possible installation of a geo-thermal system. Raising underground water for heating in winter, and cooling in summer.
