May through August was one of Illinois' hottest summers on record, with six weeks' worth of temperatures at 90 degrees or above--including a record four straight days of 100-degree heat in the Rockford area.
CUB's report, "Costly Kilowatts: How Inefficiency Burned ComEd Customers During A Record Hot Summer," shows that simple actions many people take for granted--using fewer lights, turning off the coffee maker--can help cushion customers from events over which they have little control, such as heat waves. In fact, CUB's findings suggest that energy efficiency could have saved ComEd customers nearly $50 million this summer. We have a free online tool that makes it easy to be energy efficient.
CUB's analysis was based on energy-usage data from the Energy Information Administration (EIA), the statistical arm of the Department of Energy, as well as a sample of 2,697 ComEd customers using CUBenergysaver.com, a free online energy efficiency service offered by CUB to help consumers cut their utility bills and earn rewards for saving energy.
