Energy Management
The primary mission of CMCSS is to educate and empower our nearly 40,000 students to reach their potential. Part of that mission includes fostering a stewardship mindset, instilling attitudes and actions that support environmental sustainability and energy conservation. We believe that energy efficiency and conservation are vitally important for protecting our environment, preserving our natural resources, and encouraging responsible use of our community’s tax dollars. The Energy Management Program is designed to educate everyone about energy efficiency and conservation, and promote energy-efficient habits.
CMCSS operates and maintains 42 school buildings and 12 additional support facilities. Annually, the District consumes approximately 66,000,000 kWh of electricity, 115,000,000 gallons of water & sewer, and 780,000 ccf of natural gas. The cost of these energy and utility purchases exceeds $10,000,000 annually (the equivalent of average annual household utility costs for about 2,700 single-family homes), highlighting the need for continuing to evaluate our current energy management practices across all buildings to ensure that, as the District continues to grow, our building systems remain as efficient as possible.
