Energy from inside the Earth
99 per cent of the Earth's mass are hotter than 1,000 degrees Celsius. Each day, 2.5 times the energy consumed worldwide escapes unused from the interior of the Earth into space. Could we tap this potential of geothermal energy? In Iceland, 90 per cent of households are supplied with heat from the depth and steam powers power plant turbines. In Germany, the case is more complex.
