Hydroelectric power stations in South America, Africa and California are being threatened by climate change, which is leading to a decline in water resources and, in some cases, forcing authorities to rely on more polluting fossil fuels to ensure continued supply. While some countries are continuing to invest in and develop hydroelectric projects, UN has criticised their impact on the environment and questioned hydro's future in the face of increasingly volatile weather patterns. Separately, the Greenpeace has called for a wider mix of renewable energies to be used, preventing reliance on a single source.
