The diagram shows how to produce electricity by geothermal energy,it has five stages.
At the first stage,cold water pumped down to underground through a injection well which is about 4.5 km deep.
In the next stage,cold water flow across the geothermal zone,in there cold water will be heated by hot rocks.
At the third stage,hot water pumped up to condenser through the production well.
The process in condenser,steam of water make huge pressure and inject into Generator Turbine, then make Generator Turbine to wheeling.
At the last stage,electricity generated by Generator Turbine through wheeling without breaking.
To summaries,produce electricity by geothermal energy consists of five stages,pumping down cold water,heating water by hot rocks,pumping hot water,stream driving Turbine and then generating electricity.
