The Green Cup Energy Challenge was a friendly competition and group conservation effort to measure and reduce electricity use and greenhouse gas emissions. Over the January/February utility billing cycles, 166 schools from 22 states reduced their energy demands by over 5% from the average use in the previous three years. This effort saved over 1 million kWh equating to over 1.5 million pounds of CO2 emissions. When also considering the educational experience, this challenge is providing incredible benefits.
There was also a video portion of this challenge which produced some great results. The winning video (decided by popular demand) is below.
