The Geysers: A Sustainable Energy Success Story

Discover how the injection of effluent aids in stabilizing steam production at The Geysers field in California. This innovative solution not only boosts electricity output and reduces air emissions but also mitigates induced seismicity risks, creating a cleaner and greener future. With over 50 years of production and ongoing enhancements, The Geysers exemplify the transformation of geothermal energy production. Explore how a combination of technology, environmental consciousness, and perseverance has turned this once-declining steam source into a thriving renewable energy hotspot.

  17. Best Reservoir Model…

  18. Nevertheless, the huge kettle lived happily After the shotgun date, with recycled waste Underneath The Geysers, a mile deep A huge tea-kettle was in superheat Piped-in, to inflate, and re-hydrate Enthalpy was a little downer, of late Plenty of micro earthquakes and shakes Scaring everybody, but no faults or breaks Green energy from Flush to Flash Once again, Phoenix rises from ash Rescue came from treated human waste From the counties of Sonoma and Lake Approaching single phase and no mate Beyond saturation point, in dry-out state
