Oil giant taps China's vast geothermal reserves

Chinese state-run energy giant Sinopec has drilled hundreds of wells across the country without finding a single drop of oil.While two-thirds of China's electricity is generated by coal, almost all of the homes in northern Hebei province's Xiong district -- home to 400,000 people -- are heated by wells as deep as 1,500 metres (5,000 feet)."This floor heating works like a dream," said Li Fuzeng.
