"China's government has passed a renewable energy law which is intended to increase production of energy from sustainable sources. The law, which will come into force early next year, seeks to increase the usage of solar and wind power to 10% of China's total consumption by 2010. This would equate to around 60 gigawatts. China's wind market is one of the fastest growing in the world with the exception of the US. A recent study by the Global Wind Energy Council predicted it may have installed capacity of 122 gigawatts by 2020, equivalent to the capacity of five Three Gorges dams."
