Marine renewable energy: tidal and wave projects
Marine renewable energy harnesses the power of the ocean to generate electricity, focusing on tidal and wave projects. Tidal energy utilizes the predictable movement of tides, often through underwater turbines, to produce power. Wave energy captures the kinetic energy of surface waves using specialized devices. Both methods offer sustainable, low-carbon alternatives to fossil fuels, with significant potential to contribute to global energy needs while minimizing environmental impact.

❓ Frequently Asked Questions
What is tidal energy?
Tidal energy uses the movement of ocean tides to generate electricity, typically with underwater turbines or tidal barrages that harness water flow or height differences.
What is wave energy?
Wave energy captures the energy of surface ocean waves using devices that convert wave motion into electricity, often located offshore.
How do tidal turbines generate power?
In strong tidal currents, water flow turns the turbine blades, which drives a generator to produce electricity.
Where are marine energy techs tested in the UK?
Key sites include the European Marine Energy Centre (EMEC) in Orkney for tidal and wave devices, and projects like MeyGen in the Pentland Firth.
