Hide / Show Abstract

The International Energy Agency (IEA) is leading the development of a series of roadmap for some of the most important energy technologies.  Roadmaps achieve consensus on low-carbon energy milestones, priorities for technology development, policy and regulatory frameworks, investment needs and public engagement.  As such, roadmaps can provide solid analytical footing that enables national policy makers and industry to develop specific technologies.  12 technology specific roadmaps have now been completed covering both energy supply and demand technologies.

Hide / Show Abstract

Hydropower could double its contribution by 2050, reaching 2 000 GW of global capacity and over 7 000 TWh. This achievement, driven primarily by the quest of clean electricity, could prevent annual emissions of up to 3 billion tonnes of CO2 from fossil-fuel plants. The bulk of this growth would come from large plants in emerging economies and developing countries.

Hydroelectricity’s many advantages include reliability, proven technology, large storage capacity, and very low operating and maintenance costs. Hydropower is highly flexible, a precious asset for electricity network operators, especially given rapid expansion of variable generation from other renewable energy technologies such as wind power and photovoltaics. Many hydropower plants also provide flood control, irrigation, navigation and freshwater supply.

The technology roadmap for Hydropower details action needed from policy makers to allow hydroelectric production to double, and addresses necessary conditions, including resolving environmental issues and gaining public acceptance.
