How do wegetthe geothermal energy? • Hot waterreservoirs e.g. under southern Germany orIcelandforspaceheating but not forelectricity • Natural steamreservoirs a hole dug in thegroundthatcausesthesteamtocometothesurface
Advantages of Geothermal Energy • Easy toinstall, toserveandtomaintain • The System worksabout 25 and 50 years • They do heatingandcooling • The systemsareveryenvironmentallyfriendly • Heatingofthehousingspaceand also waterpreperation
Disadvantagesof Geothermal Energy • Itis not availableand profitable everywhere • The efficencyof Geothermal Energydependsextremly on theinstalledsystem • The installationofthesearcherscancauseearthquakes in sensible regions • The aquisitioncostsareveryhighitis profitable in thelongterm
