===Geothermal heating===
Klamath Falls is located in a known geothermal resource area. [[Geothermal power]] has been used directly for [[geothermal heating]] in the area since the early 1900s. A downtown district heating system was constructed in 1981 and extended in 1982. There was public opposition to the scheme. Many homes were heated by private geothermal wells, and owners were concerned that the city system could lower the water level and/or reduce water temperatures. System operation was delayed until 1984 following an [[aquifer]] study. Full operational testing showed no negative impact on the private wells. The system was shut down again in 1986 after multiple distribution piping failures were discovered. By 1991, the distribution piping had been reconstructed, and the system was again operating. The system has been expanded since then, and according to the [[Oregon Institute of Technology]], the operation is "at or near operational break-even". The system is used to provide direct heat for homes, city schools, greenhouses, government and commercial buildings, geothermally heated [[snowmelt system]]s for sidewalks and roads, and process heat for the wastewater treatment plant.<ref>{{cite web|url=http://www.oregon.gov/ENERGY/RENEW/docs/tp124.pdf|title=Geothermal in Oregon|publisher=Geo-Heat Center, [[Oregon Institute of Technology, Klamath Falls]]|access-date=July 8, 2010}}</ref>
