FARMINGTON — United Way of the Tri-Valley Area recently launched this season’s Community Energy Challenge, a volunteer-based winterization initiative now in its sixth year.

Through the program, volunteers and homeowners build and install interior storm windows to help keep heat inside during the winter. Panels are measured, built and installed collaboratively with homeowners and trained volunteers.

No previous experience is required. Window panel workshops take place from 9 a.m. to 2 p.m. Saturdays, Oct. 11, 18 and 25, at the Mt. Blue Campus Incubator Space. Those who receive fuel assistance may qualify for up to six free window panels. Otherwise, panels cost $1.50 per linear foot. Panels are available to residents of Franklin County, Livermore, Livermore Falls, North New Portland, New Portland, Starks and Vienna.

Application deadline is Oct. 17. For more information or directions, call 778-5048.
