Understanding Hydroelectric Power

What is the primary source of energy for hydroelectric power generation?

• Geothermal energy

• Water

• Solar energy

• Wind energy

How does water flow contribute to electricity generation in hydroelectric plants?

• Water flow drives turbines in hydroelectric plants, converting mechanical energy into electricity.

• Water flow generates steam that powers the turbines.

• Water flow is used to filter impurities from the electricity.

• Water flow cools the turbines to prevent overheating.

What are the environmental impacts of hydroelectric power generation?

• Increased biodiversity

• Improved air quality

• Habitat disruption, water quality changes, sedimentation, and community displacement.

• Enhanced fish populations

Name one advantage and one disadvantage of hydroelectric power.

• High initial cost

• Increased air pollution

• Limited energy output

• Advantage: Clean energy; Disadvantage: Ecosystem disruption.

What role do dams play in hydroelectric power generation?

• Dams primarily serve as recreational areas for fishing and boating.

• Dams are used to filter water for drinking purposes.

• Dams store water to create potential energy, which is converted to kinetic energy to generate electricity through turbines.

• Dams generate electricity by burning fossil fuels.
