What is the difference between Tidal Energy and Wave Energy?

1. It is harnessed from the rise and fall of sea levels.

1. It is harnessed from waves moving along the surface of the ocean.

2. It occurs due to the gravitational pull of the moon and sun on the Earth.

2. It occurs due to wind.

3. Its intensity is affected by the location and position of the Earth.

3. Its intensity is affected by wind strength.

4. It includes two types of energy- kinetic energy and potential energy.

4. It includes only one types of energy- kinetic energy.

5. It is harnessed by using barrages, dams, tidal fences and tidal turbines.

5. It is harnessed using offshore and onshore systems.

6. It is not a continuous source of energy as it is generated for about 6-12 hours at a time.

6. It is a continuous source of energy.

7. It is more reliable since it is based on the gravitational pull of the moon and sun.

7. It is less reliable since it is based on the effect of the strength of the wind on the surface of the water.

8. Its construction cost is high, but the maintenance cost is low.

8. Its start-up cost is very high, due to its design and development which is required for the technology.
