Utilizing green energy can reduce energy costs over time. Solar panels, for example, can drastically cut electricity bills by providing free energy after the initial installation cost is recouped.
Benefits of Using Green Energy
July 30, 2013 - 67 kW (STC rating) photovoltaic array at the Mesa Verde Visitor and Research Center in Montezuma County, Colorado. The array consists of 286 Schott Poly 235 watt solar modules (13.8% efficiency) wired in 22 series strings of 13 modules per string. Coupled with a micro-hydro system and solar water heating, the on-site renewable energy systems are capable of providing 95% of the building energy requirements. (Photo by Dennis Schroeder / NREL)
