China's renewable energy sector is growing faster than its fossil fuels and nuclear power capacity. Although China currently has the world's largest installed capacity of hydro, solar and wind power, its energy needs are so large that in 2015 renewable sources provided only 24% of its electricity generation, with most of the remainder provided by coal power plants. In 2017, renewable energy comprised 36.6% of China's total installed electric power capacity, and 26.4% of total power generation, the vast majority from hydroelectric sources.
