Consumers Energy is exploring the potential use of geothermal energy to heat and cool homes in some Michigan neighborhoods. The utility is conducting a study, funded by a grant from the Michigan Public Service Commission, to determine cost-effective locations where geothermal systems could have the greatest impact.

“Our focus is one on places where we know that customers really need help with paying their bills, and so we want to reduce their costs as much as possible. Which network geothermal is incredibly efficient,” said spokesperson Tracy Wimmer.

Geothermal heating and cooling systems rely on the Earth’s constant underground temperature of about 55 degrees. These systems use a network of pipes and pumps to circulate water, drawing heat into buildings during winter and dispersing it in summer.

The study will also identify which cities have poor air quality and would benefit most from reduced emissions.

“For example, you have a business that actually needs to keep it pretty cool year-round; they can be pushing that heat out, but then other homes nearby, for example, on the system, can be using that heat. So not only is it efficient for the individual homes, but it’s efficient for whole communities,” Wimmer added.

Consumers Energy expects to complete the study by the end of the year.
