Much more work will need to be done by the rest of the world. How to get sufficiently deep is the problem.
Energy literally bubbles to the surface in some places all over the earth. Accessing this energy is simple in Iceland, which is home to more than 200 volcanoes and several natural hot springs. Steaming pools of water, heated by geothermal fires that burn close beneath the surface, are scattered throughout the nation. Geysers shoot steam and boiling jets of water into the air.
85% of Iceland’s homes are currently heated by this geothermal energy, and power plants that exploit this subterranean heat also provide 25% of the nation’s electricity.
