Hydropower

Hydropower is a key renewable energy source, utilizing dams, tidal, and wave power. Dams are common but can disrupt ecosystems. Tidal power uses underwater turbines, while wave power employs converters. Both have high costs but offer reliable energy. Hydropower is crucial for future energy needs.

Which of the following is NOT a main source of hydropower?

• Dams

• Wave power

• Tidal power

• Solar panels

What is a significant environmental concern associated with dams?

• They increase air pollution

• They alter habitats and disrupt ecosystems

• They deplete fossil fuels

• They cause earthquakes

How do tidal power systems generate electricity?

• By capturing the kinetic motion of ocean tides

• By burning fossil fuels

• By using solar panels

• By using geothermal heat

What is a challenge associated with wave farms?

• They have high running costs

• They are unreliable

• They are difficult to connect to the mainland grid

• They produce a lot of waste

Why is hydropower considered a reliable energy source?

• It can be easily stored

• It has a constant and predictable supply

• It is unaffected by weather conditions

• It has minimal environmental impact
