Geothermal heat reservoirs are renewable but not unlimited: heat is taken out of the rock by the working fluid and results in "thermal drawdown" until heat is conducted from adjacent areas. I would assume this is worse for hot dry rock enhanced geothermal systems like this one, where you don't have hydrothermal circulation moving hot water through the reservoir. Just for some graphs: https://www.osti.gov/servlets/purl/888907 https://www.osti.gov/servlets/purl/888907 . So perhaps only running your geothermal plant at night extends the lifespan of your well.
