According to recent analysis from the Citizens Utility Board, northern Illinois consumers could save nearly $150 over the course of the winter by spending 9.1 percent less energy to heat their homes and adding energy efficient practices, thanks in part to an unusually mild start to the season.

"Chicago winters usually don't hold good news for our heating bills," said Jim Chilsen, communications director for CUB. "But consumers in 2012 have a unique opportunity to save money and to use energy efficiency to make even deeper cuts in their costs."

CUB launched a website, CUBEnergySaver.com, which shows users how to use energy efficient tactics to heat their homes, while also describing some ways to use green energy.

In an effort to make buildings more energy efficient, the voluntary Builders Challenge initiative created by the U.S. Department of Energy has been the reason for more than 10,000 homes being constructed to energy efficient specifications.

The homes constructed with this initiative in mind are fitted with highly efficient walls, windows, and heating, cooling, and ventilation systems, as well as Energy Star certified lighting products and appliances.
