The Grand Ethiopian Renaissance Dam, located on the Blue Nile River in Ethiopia, has been under construction since 2011 and is expected to be complete in 2023. It impounds the Millennium Reservoir, which has been filling since 2020, and will harness hydroelectricity to bring power to nearly half of Ethiopians. The dam has created controversy with downriver countries like Sudan and Egypt, who are concerned about drought as the reservoir is rapidly filled. 11.212896°, 35.094475° Source imagery: Go
