It’s not only small islands, though, that have the chance of solving the crucial issue of energy for the future, as is shown by the example of Iceland. With its wealth of volcanoes and glaciers, the island has all the favorable preconditions you could ask for. There are now five large-scale geothermal power stations on the island, which convert volcanically heated water into electricity. Hydropower and geothermal energy meet very nearly 100 percent of Iceland’s electricity and heating demands. But the inhabitants are now taking on a further challenge: in the next step, Iceland intends to run all road vehicles and its enormous fishing fleet on hydrogen, making them CO2-free.
