> This only happens if you're pulling more energy than the long-term capacity
Well, of course that's true. The problem was the capacity was too low to be cost effective.

having said that, a resilient system would have a baseload of electricity from geothermal, some peaking from hydro and plenty of PV/wind. mind you, i'm biased since i live in NZ and we're well on the way to 95+% electricity renewables...
1. Capital expenses are quite high, even though running expenses are low.
2. It's only viable in specific geographic places, where heat is brought up close to the surface by magma and water flows. Otherwise you just need to drill too deep to get useful heat. So the big sites are at places like The Geysers in California, the hot springs of Iceland, and the places the site mentions in Kenya.
