Tidal Energy

Tidal Energy

Introduction

• Tidal energy is derived from the gravitational pull of the moon and the sun, primarily from the movement of ocean tides.

Where is it From?

• Tidal energy is generated from the rise and fall of ocean tides, driven by the gravitational forces of the moon and the sun.

Advantages of Tidal Energy

• Predictable: Tides are highly predictable, allowing for reliable energy generation.
• Clean and Renewable: Tidal energy is clean, producing no greenhouse gas emissions, and is renewable as tides continue indefinitely.
• High Energy Density: Tidal currents are dense with energy, providing significant power potential.
• Stable and Continuous: Tidal energy generation is continuous, ensuring a stable source of electricity.

Disadvantages of Tidal Energy

• Location Dependency: Tidal energy is location-specific, limiting its availability to coastal areas with strong tidal currents.
• Environmental Impact: Tidal energy projects can impact marine ecosystems and navigation routes.
• High Initial Costs: Installation and maintenance of tidal energy systems can involve substantial initial investment.
• Limited Flexibility: Tidal energy generation is dependent on tidal cycles and may not align with peak electricity demand.

Summary

• Tidal energy, derived from ocean tides, offers advantages such as predictability, cleanliness, and high energy density but faces challenges related to location dependency, environmental impact, and initial costs.
• Expanding the use of tidal energy requires careful consideration of suitable coastal locations and mitigation measures to minimise environmental effects.
