Question 09: Hydroelectricity
Introduction
Hydroelectricity is renewable electricity obtained by converting the hydraulic energy from the different flows of natural water. The kinetic energy of the water stream is transformed into mechanical energy by a turbine, and then converted into electrical energy by a generator (Tiwari 2010). Hydroelectric power ...
