Elaine Weir’s home doesn’t sit on a volcano. Nor is it surrounded by natural geysers. But that hasn’t stopped the 69-year-old retiree in Scarsdale, New York from heating her house with geothermal energy.

Every day, plastic pipes buried in Weir’s backyard draw heat from some 300 feet underground, where the earth’s temperature stays 55F (13C) year-round. Two heat pumps installed in her basement then capture the heat by circulating thermally conductive fluid in the pipes, releasing the heat to her home. In summer, that same geothermal system also cools the house.
