How to Save Energy in Illinois Homes: Local Tips and Tricks

Illinois has a mix of hot, humid summers and cold, snowy winters, making year-round energy efficiency a priority for homeowners. Whether you live in Chicago, Springfield, or a small rural town, these tips can help you keep your utility bills in check.

1. Insulate for Cold Winters

Winter heating costs can skyrocket if your home isn’t well-insulated. Illinois winters often dip well below freezing, making heat retention critical.

Tip: Seal air leaks, add insulation to attics and walls, and weatherstrip doors and windows to reduce heat loss.

2. Use Energy-Efficient Heating and Cooling

Older HVAC systems can be costly to run. A high-efficiency furnace or heat pump can save hundreds of dollars a year.

Tip: Have your HVAC system serviced annually and consider upgrading to an ENERGY STAR® model for better efficiency.

3. Manage Summer Cooling Costs

Chicago’s summer heat can push air conditioners to their limits. The key is keeping cool without overspending.

Tip: Use ceiling fans, install blackout curtains, and schedule AC use for the hottest parts of the day only.

4. Take Advantage of Illinois’ Renewable Energy Incentives

Illinois offers various rebates for solar panels, energy-efficient appliances, and smart thermostats.

Tip: Check your utility’s website for rebate programs and consider a community solar subscription if rooftop solar isn’t possible.

5. Reduce Standby Power Use

Electronics and appliances can draw power even when turned off—costing you money over time.

Tip: Use smart power strips to automatically cut power to unused devices.
