I WONDER - What Is Tidal Energy?

Tidal energy is a highly predictable form of renewable energy that harnesses the rise and fall of ocean tides to generate electricity. This is achieved through the use of special barrages or underwater turbines placed in tidal streams. As water flows in and out with the tide, it drives these turbines, producing electricity. The predictability of tides makes tidal energy a reliable source of power.

What makes tidal energy a predictable form of renewable energy?

• The consistent temperature of ocean water

• The constant speed of ocean currents

• The regular rise and fall of ocean tides

• The uniform salinity of seawater

What is the primary function of barrages or underwater turbines in tidal energy generation?

• To store energy for later use

• To filter impurities from seawater

• To convert tidal movements into electricity

• To measure the speed of tidal currents

How do underwater turbines generate electricity?

• By using solar panels

• By utilizing geothermal heat

• By harnessing wind energy

• By being driven by the flow of water

Why is tidal energy considered a reliable source of power?

• Because it is unaffected by weather conditions

• Due to the predictability of tides

• Due to its low cost of installation

• Because it can be generated anywhere in the ocean

Which of the following is NOT a characteristic of tidal energy?

• Renewable

• Unpredictable

• Reliable

• Predictable
