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

IUB has a microturbine inside the Central Heating Plant that works in parallel with our pressure reducing station valves. This turbine reduces the pressure of steam from 150 psi to 40 psi and produces electricity in that process. The microturbine is rated at 250 kW.

Two 20kW photovoltaic systems are also being installed on top of Briscoe and Tulip Tree residence halls, and are estimated to be on the grid by next year.

A brief description of RECs or other similar renewable energy products purchased during the previous year:

Indiana University Bloomington purchases renewable energy credits from Sterling Planet Inc. The REC type consists of 50% wind and 50% small hydro, where generators are located nationwide. The majority of the energy is sent to seven buildings on campus that are moving towards a LEED silver status, and the remaining is used to offset additional LEED buildings, events, and other activities on campus. Although the amount purchased is concrete, when the University will use part or the entirety of the REC energy is up to their discretion. It is currently planned out over the next four years, but subject to change. The University may also decide to purchase more REC's within this time.
