Multiple choice

Which of the following is NOT a type of marine renewable energy technology?

  1. Tidal energy

  2. Wave energy

  3. Current energy

  4. Solar energy
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Solar energy is not a marine renewable energy technology because it does not harness energy from the ocean.

Multiple choice

Which type of tidal energy technology uses a barrage to create a difference in water level?

  1. Tidal stream turbines

  2. Tidal barrages

  3. Tidal lagoons

  4. Dynamic tidal power
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Tidal barrages are tidal energy technologies that use a barrage to create a difference in water level between two bodies of water, which is then used to generate electricity.

Multiple choice
