A Little Effort Can Pay Big Dividends

The average Iowa family spends more than half of its annual household energy bill on heating and cooling. That’s a significant number, but you can dramatically reduce these costs—up to 20%, according to ENERGY STAR®—by making some simple energy-saving weatherization and insulation improvements to your home.

Energy efficiency in the home is a family matter. The appliances used, thermostat settings, insulation, and occupant habits all play a role in the amount of energy used at home. The Energy Center’s Learning Institute offers Iowans the following tools to help you make smart decisions when it comes to your energy efficiency and renewable energy projects.

Looking for energy efficiency and renewable energy incentives such as financing, tax information, and other resources? Check out these resources:

  • Rebate Programs – Iowa Utility Rebate Program
  • Assistance For Low-income – Weatherization Assistance Program (WAP) is a federal grant established to help reduce the heating and cooling costs for low income persons, particularly the elderly, disabled, and children, by improving the energy efficiency of their homes.
  • Loan Information – The Alternate Energy Loan Program (AERLP) provides loans to any individual or organization who wants to build renewable energy production facilities in Iowa. Successful applicants receive a single, low-interest loan that consists of a combination of AERLP funds and lender-provided funds.
