REYKJAVIK, Iceland, Jan. 18, 2005 — Iceland has energy to spare, and the small country has found a cutting-edge way to reduce its oil dependency. Volcanoes formed the island nation out of ash and lava, and molten rock heats huge underground lakes to the boiling point.
The hot water — energy sizzling beneath the surface — is piped into cities and stored in giant tanks, providing heat for homes, businesses and even swimming pools.
The volcanoes melted ice, which formed rivers. The water runs through turbines, providing virtually all the country's electricity.
Iceland wants to make a full conversion and plans to modify its cars, buses and trucks to run on renewable energy — with no dependence on oil.
Water Turned Into Fuel
Iceland has already started by turning water into fuel — hydrogen fuel.
Here's how it works: Electrodes split the water into hydrogen and oxygen molecules. Hydrogen electrons pass through a conductor that creates the current to power an electric engine.
