May 2011 - The Cincinnati Zoo installed a 1.56-megawatt (MW) solar canopy, generating power for the facility and providing shade for 800 parking spots at the main entrance. The solar installation consists of 6,400 solar panels designed to generate 20 percent of the zoo's electricity and save an estimated $1.5 million in electricity costs over 10 years.
The solar project will also include an educational kiosk near the zoo's Go Green garden that will allow visitors to learn about the performance of the solar arrays and benefits of solar energy.
Green energy initiatives are underway at the Philadelphia Zoo, as well, through a 2-year renewable energy certificate (REC) purchase from GDF Suez. The REC purchase represents the equivalent of 25 percent of the zoo's annual energy demand being supplied from renewable resources.
