Can the heat beneath your feet slash your energy bills by half?

How to Drill for Geothermal Energy | This Old House · 4:51 · Video: This Old House · Watch at the source

In short: This video follows Richard Trethewey as drilling begins for a geothermal system at the North Shore site. Learn how tapping into the earth's natural temperature can significantly reduce a homeowner's energy costs.

The video explores the practical application of geothermal energy, a renewable resource located just beneath the surface. By utilizing thermal storage properties found tens of feet deep, homeowners can achieve substantial savings, such as the nearly 50-percent reduction in energy bills seen at the North Shore site.

While traditional geothermal development has been concentrated near tectonic plate boundaries in locations like the western United States, Iceland, and the Philippines, advancing technologies are expanding its geographic potential. Because these resources are "always on," they offer a reliable and flexible energy solution that can be sustainable for decades or even centuries.
