I am no specialist for geothermal energy but as novice as I am I still can see that it holds appeal only in some very limited circumstances where geology brings the energy of the planet’s innards to the surface naturally. I once had a chat with a driller for geothermal and he told me about silting and keeping the water flowing and it quickly was clear to me that this is a maintenance hog. So, apart from Yellowstone, Iceland, and some other such sites, geothermal won’t ever be a decimal point to the world’s energy needs. But it feels good to chase another pig through the village.
Geothermal energy in most places is an expensive dead end. But like the masked baddie in a low budget horror flick, it won't stay in its grave, it keeps returning to the political agenda.
