A photo by @mattiasklumofficial. A river silted with sulfite wanders across the volcanic landscape of Landmannalaugur, Iceland. More than 80 percent of Iceland’s energy is derived from hydro and geothermal sources, making it the cleanest energy consumer in the world. While no country has achieved a truly sustainable society, Iceland is one of the closest to getting there. When I took this photograph I worked with the craziest heli pilot ever…. #Iceland #photographer #volcanic #Landmannalaugur #clean #energy@mattiasklumofficial @thephotosociety @natgeo by natgeo
