Key Terms

Hydroelectric Power
Electricity generated by using the energy of flowing water.

Example: Hydroelectric power plants use dams to harness river water.

Turbine
A machine that converts fluid energy into mechanical energy.

Example: Water turbines spin to generate electricity in hydroelectric plants.

Kinetic Energy
The energy an object possesses due to its motion.

Example: Flowing water has kinetic energy that can be converted to electricity.

Potential Energy
The stored energy of an object due to its position.

Example: Water stored in a dam has potential energy.

Efficiency
The ratio of useful output to total input, expressed as a percentage.

Example: A hydroelectric plant with 90% efficiency converts 90% of water energy to electricity.

Flow Rate
The volume of water flowing through a system per unit of time.

Example: Higher flow rates can increase electricity generation.
