IEA find great solution on clean geothermal energy. The presentation on minute 13:02 give the Geothermal Energy or power 25 GW on 2030 and 85 GW on 2050. No big challanges think IEA, drilling technologies and fractures or multifractures are developed by oil and gas industry, geothermal energy capacity maps are well known (see minute 16:23) and clean energy is on high demand for many reasons. The graph on minute 15:07 gives more hope on energy transition. On IEA graphs we see the Geothermal power potential on depths 5-7 km around 300 TW and drilling on oil and gas industry on these depth is usual practice, peoples understand that energy transition is very easy. We know that the world primary energy consumption is around 180000 TWh/year and these energy do not need more that 20-21 TW power and this power based on the graphs we see is only 7%. These geothermal energy can then be generated drilling on lower depths as the graph suggests.
