Common sense and simple economics are beginning to reassert themselves as the the fundamental weaknesses in the fashionable – but subsidised – expansion of solar and wind power plants are revealed. The expensive, intermittent and unpredictable generation that derives from solar and wind power plants can – at best – be used to augment an existing system. They are actually useful as an auxiliary heat and power source as small decentralised units. But in a large power grid they are more of a nuisance than an asset and can only increase the cost to the consumer.
China has now published a policy document changing direction towards nuclear and hydro power and an accelerated development of shale gas use. Solar and wind power are downgraded.
China will accelerate the use of new-energy sources such as nuclear energy and put an end to blind expansion in industries such as solar energy and wind power in 2012, Chinese Premier Wen Jiabao says in a government report published on March 5.
