Mercury Mechanical, New England Renewable Energy and others propose and discuss geothermal technology as part of the solution at the Entretech Forum

How will today's energy and building industry of manufacturers, architects, community planners, and installers meet the energy goals of tomorrow including Net Zero? Mercury and New England Renewable suggest geothermal combined with Solar Thermal and PV technologies will collectively and cost effectively achieve net zero energy goals.

Geothermal energy backers appeal to Massachusetts legislators for state incentives

New England Renewable Energy Systems president Edward Malloy says the technology he uses involves a well drilled into the ground that can extract heat, even from ground at a cool 40 degrees, or alternatively can be used to cool a home.

“These systems have been going in for a while, but very niche,” Malloy told the News Service, estimating about 5,000 such systems in place in Massachusetts. He told the committee that “99 percent” of the heat extracted from the ground is solar energy because of “the rotisserie effect of the Earth and sun.”

The administration of Gov. Deval Patrick has put its support behind Finegold’s bill as well, asking only that it include a provision requiring that thermal energy facilities have “low emissions” and “be energy efficient,” Kates-Garnick told the committee.
