Wave Energy
Electricity generation from ocean wave motion using devices that convert wave kinetic and potential energy into electricity.
Formula
Wave Power (kW/m) = 0.5 × H² × T
Real World
The Pelamis wave energy converter, developed by a Scottish company and tested off Portugal's Atlantic coast, resembled a giant sea-snake — despite promising results, the company went into administration in 2014, illustrating the commercial challenges still facing wave technology.
Exam Focus
When asked to assess wave energy's potential, always acknowledge the large resource (2 TW global) alongside the low TRL and high maintenance costs in harsh marine environments.
