The diagrams below show a structure that is used to generate electricity from wave power. 

The illustrations depict the process of generating electricity by harnessing the power of sea waves.

Overall, a purpose-built coastal structure converts the kinetic energy of waves into electrical energy through the movement of air, which drives a turbine. This cycle operates continuously as waves advance and retreat.

As shown in the first diagram, the structure is positioned against a sea wall or cliff to ensure stability against the force of incoming waves. At its base lies a reinforced chamber, likely constructed from concrete and steel, that allows seawater to enter and exit. This chamber connects to a vertical column containing a suspended turbine. When a wave surges into the chamber, the rising water compresses the air above it, forcing it upward through the column. The resulting air pressure spins the turbine, generating electricity through mechanical rotation.

The second diagram illustrates the reverse phase: as the wave recedes, air is drawn back into the chamber, maintaining airflow through the turbine. This bidirectional air movement enables the turbine to operate continuously, providing a sustainable and renewable source of energy.
