Geothermal energy is the solution for the future

 

There is a solution for the world's insatiable energy needs. It is CO2-free and safe. And its located right under our feet. Ever since Jules Verne wrote in 1864 about a trip to the Earth's interior, people have dreamed of bringing up heat from the centre of the planet. So far we have only scratched the surface, but researchers are now beginning to work down into the depths.The fact is that 99 per cent of the planet has a temperature above 1000 degrees Celsius. The heat is whats left over from when the Earth was first formed, and there is more than enough of it for us to transform it into energy. If we can drill and recover just a fraction of the geothermal heat that exists, there will be enough to supply the entire planet with energy energy that is clean and safe, says Are Lund, senior researcher at SINTEF Materials and Chemistry.
