Iceland is about as volcanically active as a place can be with a mid-ocean ridge spreading apart above water, boosted by a hotspot plume. Although geothermal power is used in Iceland, what if volcano power could be harnessed more directly?
Amazing But True!
- Iceland sits above a hotspot that lies astride the Mid-Atlantic Ridge. The island is a very geologically and volcanically active place.
- In Iceland, about 30% of the power is geothermal. They drill into hot rock, not magma.
- A volcano power plant hasn’t been created yet, but it could be a tremendous source of power.
