Band 8+: The diagram below shows how electricity is produced using an overtopping wave energy converter. Summarise the information by selecting and reporting the main features, and make somparisons where relevant.

The diagram illustrates the working methodology of an overtopping wave energy converter.

Overall, the energy converter transforms tidal energy into electricity through an offshore structure consisting of a ramp, reservoir, and turbines.

A ramp is constructed just by the sea in such a way that the waves can glide on it and reach the overtopping reservoir built just next to it. This resdivoir acts as a temporary vessel that collects water coming from the sea. Just past the reservoir, a huge dome is constructed, which has a number of turbines mounted in it. Below the turbines, another channel is constructed to collect and divert water back to the sea

During high tides, large waves reach the reservoir with the help of the ramp. When enough water is collected in the reservoir, it forcefully enters the dome and, with the help of gravitational force, rotates the turbines. The generators then convert the kinetic energy into electricity. After rotating the turbines, the water flows into the channel at the bottom, which then redireets it to the sea.
