I am guessing over a $Bill has been spent/wasted on this quest for geothermal electricity generation over 15 years. If anybody has seen other estimates please post.
In the case of Geodynamics GDY - https://au.finance.yahoo.com/q/bc?s=GDY.AX&t=my
up to late 2013 they had raised $220mill from shareholders and scored $107mill in Govt grants. So that is $327mill gone just in one ASX company. There are many other ASX companies that spent big on the geothermal energy fiasco - what other examples can readers add?
