An Alliance to Help Illinois Residents Lower Their Energy Costs

Frequently Asked Questions

What is Energy Impact Illinois?

The Energy Impact Illinois (EI2) program will connect you with a trusted energy advocate to help you identify how your home uses energy – and wastes it – and identify the most cost-effective improvements you can make for a more efficient and comfortable home. We’ll serve as your advocate through the entire process and help you find rebates and loans to reduce the cost of energy efficiency improvements. The Energy Impact Illinois program is led by Elevate Energy, a nonprofit organization dedicated to smarter energy use for all.

Why should I make my home, building, or business energy efficient?

  • It will help you save money. Products that use energy have operating costs. You may not consider this when you are choosing a refrigerator, air conditioner or furnace, but an energy efficient product that may cost more initially will cost less over time. If your business uses energy, investing in energy efficiency may reduce your cost of operations and increase overall profitability. In many cases the initial costs of energy efficient products can be reduced by taking advantage of rebates or incentives.
  • Do your part to protect the environment. Using less energy reduces the amount of carbon dioxide and other pollutants released into the atmosphere when fossil fuels are burned.
  • Provide a boost to the economy. If you spent less on energy bills, you could spend more on other things that provide a greater economic impact. Also, making energy efficiency improvements to homes and businesses helps create new jobs.
  • Homes that complete the EI2 program are warmer in the winter and cooler in the summer, keeping your family more comfortable.
  • If your home becomes 15 percent more efficient, you’ll also qualify for the Illinois Home Performance with ENERGY STAR™ certificate, which proves to prospective home buyers that your home is energy efficient. Research suggests that homes with these certificates sell faster and at higher prices.
  • Improve energy security. Energy is required for our state and country to function. By ensuring that our demand does not exceed our supply, we ensure that the system is stable and reliable.

How do I know that I’ll see savings if I invest in energy efficiency?

While energy bills can vary with the seasons (e.g. higher gas bills in the winter), the amount of use during a typical season should indicate if your efficiency is improving. Also, some efficiency improvements will provide more noticeable benefits than others. For example, an insulation and air sealing improvement would likely provide more monthly savings than replacing windows.

Which programs and incentives am I eligible for?

Energy Impact Illinois has programs for residents and businesses in Cook, Lake, Kane, DuPage, McHenry, Will or Kendall counties or in the City of Rockford. Use the "Find Energy Savings Actions" tool to see all the programs you qualify for, based on your location and home or business type.
