8. Describe one energy conversion that takes place during the generation of hydroelectric power.

When water flows from a high elevation to a lower one, its potential energy is converted into kinetic energy. This moving water turns the blades of a turbine, and as the turbine spins, it converts that kinetic energy into mechanical energy. Finally, the turbine is connected to a generator, which transforms the mechanical energy into electrical energy, allowing us to power our homes and businesses! In addition to being a renewable source of energy, hydroelectric power plays a significant role in flood control and water supply management. Reservoirs created for hydroelectric plants can store excess rainwater, helping to prevent flooding downstream. They also can provide water for irrigation during drier seasons—talk about a multitasking energy source!
