Governments around the world have committed to make the transition to renewable energy. This will not be possible without the flexibility and consistency that sustainable hydropower brings to the renewable energy mix. In fact, to meet climate targets and the SDGs, the International Renewable Agency (IRENA) estimates that the world will need another 1,000 GW of hydropower installed capacity in the next 30 years. This is equivalent to the amount which has been built in the last 70 years.

The International Hydropower Association (IHA) is the international voice of sustainable hydropower.  It seeks to help governments, companies, financial institutions and NGOs deliver this transition. It is a non-profit membership organisation which works with its members and partners to build and share knowledge on hydropower’s role in renewable energy systems, responsible freshwater management and climate change solutions.
