Does Africa have hydroelectric power?
Hydropower power generation is likely to grow rapidly in sub-Saharan Africa. Hydropower represents a significant source of electricity production in eastern and southern Africa. Currently 90% of national electricity generation in Ethiopia, Malawi, Mozambique, Namibia and Zambia comes from hydropower.
How do dams create power?
An impoundment facility, typically a large hydropower system, uses a dam to store river water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.
