Could the answer to 100% renewable energy in Dominica be under the ground?

A small but growing number of countries are well on their way to producing all of their electricity from renewable sources. Dominica, in the eastern Caribbean, is planning to join these pioneers and become the first small island developing State (SIDS) to stop using fossil fuels for energy generation.

It's called geothermal energy, and it's an exciting prospect for the country. Geothermal has none of the intermittency issues of wind and solar – in other words, it provides stable energy day and night – and doesn't take up any surface real estate, keeping the Roseau Valley in its pristine state.
