Iceland is in an excellent position to become energy independent, because there is now technology that makes it possible to generate an electrical current using heat, which Iceland has plenty of in the form of geothermal energy. And if Iceland becomes energy independent, it can also grow a lot of its own food in the winter in hot houses and hydroponically.   And it can fuel its fleet of vehicles using electricity generated in this way as well. The problem would be getting by until everything was set up to do this.
