The panel discussion will include general information about geothermal energy — what it is, what it costs and what residential options it offers, according to program organizers.

Brian Gaulzetti, senior energy consultant at Dandelion Energy, will provide an overview of how geothermal works. EnergizeCT consultants James Lewis and Malik Arif will discuss incentives and no-cost consultation services available to residents.

And Westport resident Michael Anderson, who installed a geothermal unit at his home, will discuss his experiences.

A question-and-answer period will follow the discussion.
