IEA offers roadmap for doubling global hydropower by 2050
The International Energy Agency (IEA) and Brazil`s Ministry of Mines and Energy have published a report laying out a roadmap for doubling global hydroelectricity production by 2050. According to IEA, the achievement of such hydro production levels could prevent up to three billion tons of carbon dioxide emissions from fossil fuel plants. By 2050, a doubling in hydroelectric production would imply an increase in global capacity to almost 2,000 gigawatts (GW), and global electricity generation to over 7,000 terawatt hours (TWh). According to the report, much of this growth would come from developing ... | ||
