Global hydropower potential: 33% of total energy requirement

News - 09 February 2017

The Delft researchers used a model combining various geographical information systems to create a simulation of the global potential of electricity generated using hydropower. All of the world’s rivers with a discharge exceeding 100 litres/s were replicated, resulting in an extremely extensive database containing a network of rivers.
Additional data was used to chart the gradients of these rivers, with the aim of determining suitable locations for hydroelectric power stations. The research offers insight into the spatial distribution of hydropower and the amount of energy that the approach could theoretically generate in a specific area.

Replacement of fossil fuels

Hydropower could potentially replace a significant part of the contribution currently made by fossil fuels to energy production. This study is the first of its kind to present a detailed evaluation of the potential contribution of hydropower at each location, based on the slope and discharge of all of the world’s rivers. Hydropower represents a total theoretical contribution of approximately 52 PWh/year, distributed amongst 11.8 million locations. This amounts to 33% of the annual global energy requirement; hydroelectric power stations currently account for 3% of this annual energy requirement.
