wave power
B2-C1Technical / Academic / Environmental Policy
Definition
Meaning
Electrical power generated by harnessing the energy from ocean waves.
A form of renewable energy technology that captures the kinetic energy of ocean surface waves and converts it to electricity.
Linguistics
Semantic Notes
Primarily an uncountable noun phrase referring to the concept/technology; can be used attributively (e.g., 'wave power station'). Less common than 'solar' or 'wind' power in general discourse.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning. The term is equally technical in both varieties. The UK, with its long coastline, has more prominent commercial and research projects, making the term slightly more frequent in UK environmental policy and news.
Connotations
Connotes clean, renewable energy, marine technology, and often futuristic or niche energy solutions. May imply challenges of reliability and infrastructure.
Frequency
Low frequency in everyday conversation; moderate in environmental science, engineering, and policy contexts.

Common Pitfalls
Translation Traps (for Russian speakers)
- False friend: 'волновая мощность' is a direct calque but is not the standard term. The correct translation is 'энергия волн' or 'волновая энергия'. 'Мощность' relates more to 'capacity' or 'output power'.
Common Mistakes
- Using as a countable noun (*'a wave power').
- Confusing with 'tidal power' (which uses tidal currents, not surface waves).
- Misspelling as 'wavepower' (should be two words or hyphenated as a compound modifier: 'wave-power device').

FAQ
Frequently Asked Questions
No. Wave power specifically converts the energy of wind-driven surface waves. Tidal energy harnesses the kinetic or potential energy from the predictable rise and fall of tides caused by gravitational forces.
It is a predictable and abundant renewable resource with high energy density, especially in coastal regions. It produces no greenhouse gas emissions during operation.
High costs for installation and maintenance, technological reliability in harsh marine environments, potential environmental impacts on marine ecosystems, and the challenge of transmitting electricity to shore.
At a commercial scale, it is still limited. Pilot projects and small-scale installations exist in places like the United Kingdom (Scotland, Orkney), Portugal, Australia, and the United States (Hawaii, Oregon).
