Reykjavík


Reykjavik city centre, Flickr, Creative CommonsReykjavík is the capital of Island, a city with 120 thousand habitants and the most populous in the country. The city had a significant development after the second world war, with the modernisation and population growth.
Reykjavík is one of the top sustainable cities in the world - figuring in the top of many ranks considering carbon emissions. The main reason is that the city is largely powered by renewable energy - the geothermal activity from its surroundings is converted into energy, and distributed to the city, being responsible for almost 95% of the heating of the city, nothing even seen in another contemporary city in the world.
In 2006, 26,5% of electricity originated from geothermal sources, 73,4% from hydropower and only 0,1% from other sources. Some estimative show that annually the use of renewable sources to produce energy made Reykjavík save 4 million tons of CO2 from its emissions between 1944 and 2006 . The city's plan is that by 2050 the city will be completely free from fossil fuels.
