Total energy consumption (all sources, excluding transportation fuels), performance year :
152,238 MMBtu

Total clean and renewable electricity generated on site during the performance year and for which the institution retains or has retired the associated environmental attributes:
108.10 MMBtu

A brief description of on-site renewable electricity generating devices :

During the 2015-16 reporting year, HSU facilities hosted four solar PV systems: a 2.5 kW system on the Natural History Museum, a 2.5 kW system on the Campus Center for Appropriate Technology, and a 12.5 kW system on the Music A building. HSU’s Schatz Energy Research Center (SERC) also managed a 7 kW system at the Telonicher Marine Lab, which was installed in 1990 to power a 1 hp compressor motor that aerated the fish tanks at the marine lab. Excess solar power was stored as hydrogen (by electrolyzing water), which was used in a fuel cell to keep the compressor running in times of no sun. In 2011 this system became grid tied under a net metering agreement. In 2016 the system was retired since the modules had reached the end of their useful life.
