Iceland is the world's leading nation in utilising renewable energy, with 72 percent of its total energy consumption from hydro and geothermal sources. A volcanic island with abundance of renewable energy sources and a small nation with an innovative mindset provides for an exciting case study on how to move towards a 100 percent sustainable energy society. The country's ski resorts, including the largest Blafjoll, already use more-or-less 100 percent renewable energy as most of the non-renewable energy currently used is consumed by cars and boats. Facilities include state of the art geothermal power plants, visits to a biogas production facility and the world's first hydrogen refuelling station. The sources of Iceland's renewable energy are best enjoyed by visiting Iceland's many spectacular waterfalls, hot springs and geysers, and of course by relaxing in the Blue Lagoon outdoor spa under a starlit sky in the middle of a lava field.
