Tidal Energy Sources

Tidal energy is a renewable energy source that harnesses the power of ocean tides caused by the gravitational pull of the moon and sun.
The rise and fall of ocean waters creates high and low tides, which can be used to generate electricity.

Methods of Tidal Energy Production

Tidal turbines: underwater windmill-like machines that convert tidal energy into electricity.
Tidal barrages: turbines placed inside a dam-like structure that closes and opens with the tide to produce energy.
Tidal lagoons: enclosed bodies of ocean water along a natural coastline that generate continuous power.

Characteristics of Tidal Energy

Renewable energy source due to the moon's gravitational pull.
Inexhaustible energy supply as long as the moon orbits the earth.
Predictable energy source due to the moon's relationship with the tides.
Clean and cheap energy source with zero greenhouse gas emissions.

Advantages of Tidal Energy

High energy density due to the density of water.
Reliable source of energy compared to wind and solar energy.

Disadvantages of Tidal Energy

High upfront costs for constructing turbines and barrages.
Limited suitable locations with significant tidal ranges.
Potential detriments to marine life, such as disruption of fish migration and killing of fish by turbines.
Intermittent nature requires reliable energy storage systems.
Difficult to transport generators to remote locations.
Vulnerability to severe weather conditions, such as hurricanes and typhoons.
