Geothermal energy has the potential to provide all our human energy requirements for millions of years. The trouble is we just can`t easily get at it other than in areas of volcanic activity or along fault lines in the earth`s tectonic plates. So geothermal energy has always remained a niche energy source - accounting for just 1% of global energy. Now a Canadian company has developed a system that can work profitably anywhere in the world, regardless of geological conditions. This one could be a winner!!
