Geothermal power is energy generated from heat stored in the earth, or the collection of absorbed heat derived from underground.As of 2008, geothermal power supplies less than 1% of the world’s energy. Geothermal resources range from shallow ground to hot water and rock several miles below the Earth’s surface, and even further down to the extremely hot molten rock called magma. Wells over a mile deep can be drilled into underground reservoirs to tap steam and very hot water that can be brought to the surface for use in a variety of applications.

Geothermal Possibilities in the Caribbean
Saint Kitts and Nevis
The island of Nevis, long known for its numerous hot springs, commenced drilling for the construction of a geothermal power plant at Spring Hill, Nevis, in January 2008. When completed (estimated 2010), the plant will supply 50 megawatts of electricity, enough to fulfill all of Nevis’ demand (approximately 10 megawatts), and also enough to export to neighboring Saint Kitts as well as other nearby islands via submarine electrical transmission cables. The project, being undertaken by West Indies Power, will make Saint Kitts and Nevis the first country in the Caribbean to utilize large-scale Geothermal energy, and, when complete, will make Saint Kitts and Nevis one of the least dependent nations in the world on fossil-fuels.
Project in Dominica
The Government of Dominica awarded geothermal exploration and development license to West Indies Power (Dominica) Ltd. on 10 July 2008. Initial geologic and geochemical field exploration work will begin in August 2008. Based on the results of the thermal gradient holes slim holes will be drilled in 2009 and the geothermal power plant will be constructed in 2010.
Project in Saba
In Saba, West Indies Power develops geothermal power plant with capacity of 75 MW.
