Market Potential<br />
Like the energy of the sun, the energy within the earth is immense and has a<br />
lifetime measured in billions of years. However, geothermal energy is<br />
accessible in limited areas, and unlike the use of sunlight, tapping into local<br />
sources of the earth’s heat can result in a temporary decrease in the amount<br />
of energy locally available. Even with re-injection of the geothermal fluid, the<br />
heat content of the reservoir gradually declines. The recovery period for a<br />
geothermal resource depends on how it is used. Resources tapped for<br />
electricity generation could provide energy for 50 years or more if properly<br />
managed. Typically, the plant equipment reaches the end of its useful life<br />
before the resource is depleted. Continuous long-term use of geothermal<br />
energy for electricity generation would require the periodic construction of<br />
new plants at new sites, while previously-used reservoirs recover.<br />
About 0.2% of the surface in Europe has “very good suitability” for<br />
geothermal power (Iceland, Azores, Canaries, pre-Apennine belt of Tuscany<br />
and Latium, Aeolian islands, Aegean islands and Western Anatolia). About<br />
2.5% presents “good suitability” (areas on the border of the abovementioned<br />
regions, Massif Central, Rhine Graben, Campidano Graben,<br />
Pannonian Basin and the island of Lesbos). In these areas, several GW of<br />
geothermal power capacity could be installed in the coming decades and<br />
support rising power demand.<br />
The geothermal potential capacity over the next 30 years is more than ten<br />
times the capacity currently installed. The U.S. Geothermal Energy<br />
Association predicts for several world regions the potential capacity for the<br />
next 30 years as 22 GW in Central America, 10 GW in East Africa, 16 GW in<br />
Indonesia, 8 GW in the Philippines and 23 GW in the U.S. World potential<br />
capacity for geothermal power generation is estimated at 85 GW over the<br />
next 30 years, about 10 times current installed capacity.<br />
<strong>Technology</strong> Factors<br />
Geothermal power plants supply more than 10% of the national power in<br />
some countries, in those countries where geothermal resources are<br />
abundant and competitive. In addition to these large-scale, cost competitive<br />
applications, small-scale applications are approaching the cost range where<br />
geothermal can compete for special applications and/or power supply in<br />
remote areas. In these areas, geothermal plants might provide base-load<br />
electricity. Following are areas for market growth:<br />
