Thermal images that show where homes are leaking valuable heat are available for free, and a workshop on how to access them is planned Thursday evening, Feb. 27, at Earthplace.

The free workshop at the 10 Woodside Lane nature center is sponsored by the Westport Green Task Force. It begins at 6:30 p.m. with wine and light refreshments, followed the program at 7.

The program will include discussion of energy-efficiency opportunities available to homeowners, the task force said.

Thermal images are accompanied by reports that detail energy leaks and recommend how to reduce them.
