Why is most geothermal energy untapped?

Geothermal energy – used in over 20 countries, in particular the US and Iceland – is the heat that comes from the sub-surface of the earth, contained in the rocks and fluids beneath the planet’s crust.

Producing power from geothermal energy relies on wells that are dug a mile deep into underground reservoirs, to access the steam and hot water there, which can then be used to drive turbines connected to electricity generators.

As far as output is concerned, the potential of geothermal energy would appear to be enormous. In fact, if estimates are correct, the heat under our feet amounts to 50,000 times more power than all the oil and gas resources in the world. So, why isn’t this renewable energy more widely deployed?
