Environmental considerations for geothermal energy as a source for district heating.

Author(s) : RAFFERTY K. D.

Summary

Geothermal energy currently provides a stable and environmentally attractive heat source for approximately 20 district heating systems in the United States. The use of this resource eliminates nearly 100% of the conventional fuel consumption (and, hence, the emissions) of the loads served by these systems. The cost of producing heat from a geothermal resource amounts to an average of USD 1 per million British thermal unit. The major environmental challenge for geothermal systems is proper management of the producing aquifer. Many systems are moving toward injection of the geothermal fluids to ensure long-term production.
