​MILWAUKEE— Soon, 50 low-income homeowners in Milwaukee and Waukesha counties will get their home systems upgraded to be energy efficient and less expensive. 

The Wisconsin Public Service Commission announced Tuesday it's awarding $500,000 grants to Revitalize Milwaukee and Green Homeowners United. 

CEO of Revitalize Milwaukee Lynnea Katz-Petted said the repairs will help people who are paying high bills for heating and air conditioning every month thanks to old units. Plus, Katz-Petted said those units are likely putting out higher carbon emissions. 

Katz-Petted said veterans, the disabled, and the elderly are likely to be chosen as the 50 homeowners to get their systems replaced. She said they'll be most helped by having lower bills, because many are on a fixed income.
