IEA considers doubling hydroelectricity by 2050

The IEA has recently published a report considering the effects of a 50% increase in hydroelectricity production between now and 2050. 

The IEA report considered this 50% increased in hydroelectric power based on global electricity production presenting that the largest untapped potential exists in Asia, Africa, and Latin America. They also mentioned the interesting potential of other variable renewable energy sources (wind and solar) to fill pump-storage reservoirs when the production was high and demand was low.
