It is interesting - and difficult to believe - that the EU will double its use of geothermal between now and 2050 as illustrated in the chart that contains the projections for industrial heat. I wonder if they mean conventional geothermal - like the Larderello facility - or the ground-sourced heat-pump-based technology. In any event, geothermal is widely considerd "free" --- so this begs the question why haven't the EU already emabarked on this path?
