CENTENNIAL, Colo. (Oct. 7, 2026) – Colorado Natural Gas, a subsidiary of Summit Utilities, is joining utilities, businesses, government agencies, and energy advocates across the country to recognize Energy Efficiency Day and encourage customers to take simple steps to reduce energy use and manage household energy costs.

Held annually on the first Wednesday in October, Energy Efficiency Day highlights the benefits of reducing wasted energy, from lower household costs to improved comfort.

“Energy Efficiency Day is a good reminder that small changes at home can add up over time,” said John Ware, senior director of customer development and growth at Summit Utilities. “Simple habits and routine maintenance can help customers get more from the energy they use while keeping their homes comfortable.”

Colorado Natural Gas encourages customers to consider these energy-saving tips:

• Use a programmable or smart thermostat to better manage heating and cooling.
• Seal gaps around doors and windows with caulking or weather stripping.
• Replace air filters regularly and keep vents open for proper airflow.
• Set water heaters to 120 degrees Fahrenheit to help reduce energy use.
• Wash clothes in cold water and avoid over-drying laundry. Use ceiling fans strategically by setting them to rotate clockwise during colder months.
