Potential for power from geothermal sources is wide-ranging and ever-present in many regions. The one potential problem with utilizing a geothermal source is the expense of drilling to find out exactly where it is situated. New seismic tools are now available to locate geothermal veins more easily. With this new technique, companies don’t have to be as concerned about the cost of drilling and finding nothing.

Scotland is among the many countries discovering how useful geothermal energy to heat structures can be. New houses being built in regions of Scotland, such as Hawick in the southeast portion of the country, are incorporating geothermal energy in their construction. A recently built primary school in Denholm is also utilizing geothermal sources as part of its combined energy answer.

Testing in Newcastle, part of southwest Dublin, is showing in early reports that approximately 10,000 area homes could potentially see benefits from a system of extracting heat that is lying in a geothermal reserve between 4,000m and 5,000m below the ground surface. Hopes are optimistic that within five to seven years, 15 percent of heating and hot water sources used in Dublin could be available through the use of geothermal energy.

Twenty-five years ago, Alaska landowners couldn’t get anyone interested in any of the 16 tracts of land believed to be hovering over geothermal resources on the south side of Mount Spurr. Today, however, another story is evolving. Recently, when the lands were offered for lease again, all 16 tracts received bids including offers from some of the biggest players in the world among geothermal plant manufacturers: Ormat Technologies, Inc. and Iceland America Energy, Inc.

It goes to show that sometimes the old ways, and the natural ways, are the best. Back in simpler times, when life was more direct, the Shoshone Native American tribal people used natural hot water to warm the village in the winter as they camped. The Shoshone Nation in Honeyville, Utah, is using the same basic principles and elements today as they prepare to build five geothermal plants and sell the energy produced to residents of Riverside, California.

Just after Hurricane Omar passed Nevis, the West Indies Power company’s No. 3 well, located at Hamilton Estate, spouted off with a strong gush of steam. There was found to be an unbroken geothermal reservoir between Nevis No. 1 well (located at Spring Hill) and No. 3 that maintained the high temperatures and steam associated with a usable geothermal resource. Officials now believe the opportunity is wide-ranging for geothermal energy to produce hundreds of megawatts of power for the citizens of Nevis and surrounding regions.
