What is Tidal Energy?
Tidal energy, also known as ocean energy, is a form of renewable power that harnesses the gravitational forces of the Earth’s oceans to generate electricity. It works by capturing the kinetic energy from tidal movements, using various types of tidal systems such as tidal stream and tidal range technologies.
Definition
Tidal energy harnesses the power of the ocean’s tides, a form of hydroelectric power that converts movement into electricity. Gravitational forces between the earth, moon, and sun drive these tidal movements, creating a consistent pattern of rising and falling sea levels.
This renewable resource taps into the immense kinetic energy generated by these natural processes.
We capture this green energy through various technologies stationed along coastlines where tidal shifts are most pronounced. As environmentally conscious individuals understand, exploiting the rhythmic ebb and flow offers a reliable source of clean energy.
By turning to tidal systems for sustainable power generation, we embrace alternative practices essential for our planet’s health and coastal resilience.
How it works
Tidal energy works by harnessing the power of the ocean’s tides to generate electricity through the use of tidal turbines. These turbines are placed underwater in areas with strong tidal currents, and as the water moves back and forth, it causes the blades of the turbine to spin, converting kinetic energy into electrical power.
There are two main types of tidal systems: tidal stream systems that use underwater turbines similar to wind turbines, and barrage systems that utilise large dams or barriers to capture and release seawater through a series of tunnels, driving turbines to produce electricity.
The process of generating tidal energy is efficient and emissions-free. As tides are predictable, this form of renewable energy offers a reliable source of power generation without relying on fossil fuels.
Types of tidal systems
Tidal energy comes in two main forms: tidal stream systems and tidal range systems. Both types harness the power of the tides to generate electricity.
- Tidal Stream Systems: These systems use turbines to capture the kinetic energy from moving water currents caused by the ebb and flow of the tides. The turbines are positioned underwater, much like an underwater wind turbine, and are designed to rotate as water passes through them.
- Tidal Range Systems: Tidal range systems utilise the difference in height between high and low tides to generate electricity. One common form is a barrage, which is a dam-like structure built across an estuary or bay. As the tide comes in, the barrage gates close, trapping water inside. When the tide goes out, the gates open, allowing water to flow through turbines to generate electricity.
