However, there are places in the word that are still dominated by coal-fired generation, for example in China, 93% of aluminium production gets its power from coal fired power plants. When hydroelectric power is used just 4 tonnes of carbon dioxide is emitted into the atmosphere per each tonne of aluminium produced, but when coal-fired generation is used, five times as much carbon dioxide is
