We are looking ahead to extremely cold weather across the Midwest, coming in tomorrow through early next week. The City of Winfield says Our utilities are working together with electric grid operators and power and natural gas suppliers to coordinate the safe and reliable delivery of energy. One of the easiest ways to minimize the energy cost impact to your household or business is by lowering the thermostat during the extreme cold period. For every degree you lower your thermostat below 70, you’ll save between 1% and 3% on your heating costs. Just a 2-degree decrease, from 70 to 68 degrees, could cut as much as 6% on your heating costs.
