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

Colorado State University is home to 6 major photovoltaic arrays on campus. In total, these systems generate 237 KW annually.


A brief description of on-site renewable non-electric energy devices:

A biomass boiler on CSU campus generates hot water and displaces natural gas use. This plant has a rating of 46 bhp.


A brief description of off-site, institution-catalyzed, renewable electricity generating devices:

A meterological tower was installed as the first phase to investigate the viability of installing wind turbines on a 3000 acre university owned site, 100 miles east of the main campus.


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

One year of REC s were purchased to off-set the electric use in common spaces at the residence halls and two years of electricity were purchased to off-set the use of two new LEED certified buildings on campus.

CSU also has a wind power purchasing program from the local municipality.


A brief description of cogeneration technologies deployed:

The Steam Turbine generates electricity from energy that was previously lost.


The website URL where information about the institution's renewable energy sources is available:

CSU is the site host for 5,300kW (8.5M kWh/yr) solar plant on the foothills campus - one of the largest in the country and one of the largest associated with a college/university campus. The RECs were sold to the local utility in order to finance the plant. CSU will be able to claim the REC's in 2030.
