Geothermal Energy in Iceland

Lots of my A Level geographers will be able to tell me that Iceland's energy mix is almost 100% renewable however there is another side to the story. We came across this page from an organisation call 'Saving Iceland' when researching the issue together which contains some interesting blog posts regarding the environmental impact of Iceland's utilisation of geothermal energy http://www.savingiceland.org/tag/geothermal-energy/. As with all sources of evidence they should be read with a critical eye.
