This works in Iceland because it's easier to get to the hot places. They pump water down fissures, the steam comes up to power steam generators, and they actually pump the water back up and send it miles away as hot water to Reykjavik.

It's effective because the fissures make it easier to implement this process.

If I remember correctly there are experimental drill holes in Iceland that go much deeper. The hope is that these deeper drill holes provide specialized knowledge that could be exported internationally. However I’m not sure if this project has yielded any positive results. I was actually raised pretty close to one of these experiments which started in 2006.
