Geothermal Icon

Geothermal is a growing alternative energy source for heating and cooling. Depending on its application, the cost can be competitive with wind and solar. Tax credits may be available to help defray the cost.
Will County is partnering with the Citizens Utility Board to offer information with on-line and in-person presentations. A group purchase is available in 2023 and may be offered again.
2005 Data from the U.S. Department of Energy’s National Renewable Energy Laboratory on the cost per kilowatt-hour at active power generation projects:
·         Geothermal, $0.031 to $0.08
·         Wind, $0.043 to $0.055 
·         Biomass, $0.066 to $0.08                  
·         Solar, $0.11 to $0.31
·         Hydroelectric, $0.006 
·         Coal $0.021
·         Nuclear, $0.022
These costs most certainly have changed over the last few years, but provide an indication of the cost effectiveness of installing geothermal in homes, businesses and schools.
