Arnold, who is from the USA, sent me this great postcard of a geothermal site in Iceland on his trip there. Iceland has an enormous capacity to generate geothermal energy what with all those volcanoes of theirs. During winter, pavements of the areas near these geothermal sites are heated up, which causes the heat to rise to the surface. Pretty cool, don’t you think? Iceland has 5 geothermal plants which produce 26.2% of its energy needs. 73.8% of the nation’s energy needs come from hydroelectric power and 0.1% from fossil fuels. Talk about green! 87% of Iceland’s buildings receive hot water from geothermal sites. Very interesting! Thanks Arnold.
