Colder nights are upon us and now is the time residents are asked to check their homes for ways to lower energy costs. As an incentive, Green Bay residents can get hundreds of dollars in rebates for conducting a home energy audit. The audit can help you find out what changes you can make to use less energy and save money on your utility bills. To qualify for the energy audit rebates you have to fill out an application ahead of time. You can get those at Green Bay City Hall.
