Energy water can provide 33% of current electricity demand Bashny.Net

Scientists from Delft University in the Netherlands calculated that the total potential of hydropower generation reaches 52 petawatt/hours per year. This is about a third of the entire global electricity demand.In the study, researchers analyzed 11.8 million locations, which theoretically can be used to generate hydropower. However, the researchers note that not all of them are in fact suitable for construction of hydropower plants — "for technical or economic reasons."





Total generation capacity includes all the number of electricity that could theoretically be generated assuming the use of all water resources. However, there are still technical and economic obstacles, remind the authors of the study. The ratio of technically feasible and economically beneficial locations to the total potential production is 20% and 16% respectively.

It turns out that if we consider only economically favorable locations for hydroelectric power generation, the realistic potential production of approximately 9% of global electricity demand. At the moment the share of hydropower in the total volume of all consumed electricity is about 3%.





Previously, Finnish researchers from Lappeenranta University of Technology have created a simulation world energy system fully based on renewable sources of energy. According to the researchers, such a system can be built in reality by 2030. published
