Alaska's wild solutions

The US state of Alaska may be known for its rugged wilderness, but it’s also quietly leading a green revolution. We explore how an island community is powering itself through a locally built and managed microgrid - cutting out fossil fuels and slashing energy costs. And we find out how scientists are using native mushrooms to produce sustainable building insulation and cold fish storage boxes that could help promote sustainability both in Alaska and beyond.
