A. However, not everyone is convinced that this is the way forward. Experts maintain that compared to the geological time scale of oil regeneration, geothermal energy is relatively renewable.
B. In less than a decade, these new plants were producing 870,000 tonnes annually, virtually all destined for overseas markets. Soon, such exports were eclipsing fisheries exports in value for the first time in the island's history.
C. Not only that, but Iceland's geothermal power sector as a whole is likely to incur public criticism. Given that the industry has already drawn some negative publicity, it could do without further condemnation.
D. Geothermal resources may be renewable if used sustainably, but they aren't emissions free, as locals and visitors who walk the streets of Iceland's capital can testify. However, emissions rates associated with geothermal power plants are much lower than emissions from coal or natural gas-fired power plants.
E. Given the vast amounts of energy flowing just below the ground, it's little wonder that Iceland is now pushing the boundaries of geothermal technology and resource use. While naturally hot water has long been
harnessed by Iceland's inhabitants, it wasn't until the oil and gas price hikes of the 1970s that the island began to use it to produce electricity.
F. Acting on these requirements, experiments and projects are underway at various sites to ensure that the situation is brought under control. It should soon be clear how successful they've been.
G. It was recently announced, for example, that the national power company had signed an agreement to supply power to a new silicon production plant being constructed in Helguvik on Iceland's southwest coast. Ecologists, however, have renewed their concerns.
