Question

The two general approaches used in modern hydroelectric power generation are:

Option 1: Tidal and Wave
Option 2: Run-of-the-river and Reservoir
Option 3: Geothermal and Biomass
Option 4: Solar and Wind

Answer 1

The two general approaches used in modern hydroelectric power generation are run-of-the-river and reservoir. In a run-of-the-river system, a portion of a river's water is diverted to generate electricity.

Step-by-step explanation:

The two general approaches used in modern hydroelectric power generation are: Run-of-the-river and Reservoir. In a run-of-the-river system, a portion of a river's water is diverted to a waterwheel or turbine, which generates electricity. This approach does not require large storage reservoirs. In a reservoir system, water is stored behind a dam, and when released, the potential energy of the water is converted to kinetic energy to turn blades of turbines and generate electricity.
