Energy efficiency is often taken for granted as an important and results-driven business for utilities and customers alike to invest in. But it's important to measure, verify, and check in on the results at are actually coming from then to ensure that the value is really worth the effort.

In that spirit, coming across this story on ComEd's energy efficiency program is eye-opening at just how effective energy efficiency savings can be. In an announcement last Tuesday, the utility noted that they had saved their customers a total of $4 billion (yes billion with a b!) since they introduced the ComEd Energy Efficiency Program in 2008.

Through the ComEd Energy Efficiency Program, customers are offered energy assessments, rebates, discounts on efficient products, and recycling programs, all designed to help them reduce energy and thus their monthly power bills. The $4 billion in savings came, in part, from the purchase of over 130 million energy efficient lights, more than $956 million in incentives for efficiency upgrades, and over 44,000 income-eligible customers in 2018 alone participating in the Future Energy Jobs Act.

Consider this a success story already, though based on these results there's no sign that ComEd has any intention of taking their foot off the pedal!
