water power
C1Formal, Technical
Definition
Meaning
The power derived from the force or energy of moving or falling water, used to drive machinery or generate electricity.
More broadly, it can refer to the political or strategic control over water resources, or the capacity or potential energy inherent in a body of water.
Linguistics
Semantic Notes
Primarily an uncountable noun phrase. The concept is historically linked to mills and, in modern contexts, almost exclusively to hydroelectricity. It implies a natural, renewable source of energy.
Dialectal Variation
British vs American Usage
Differences
The term itself is identical, but related terminology differs (e.g., UK: "hydroelectric power station", US: "hydroelectric power plant"). The concept is more geographically relevant in regions with significant waterways.
Connotations
Connotes sustainability, renewable energy, and historical industrial development. In certain contexts, it can also imply environmental concerns regarding dam construction.
Frequency
Similar frequency in both varieties, but more common in technical, environmental, and historical discussions than in everyday conversation.

Usage
Context Usage
Business
The feasibility study emphasised the long-term cost benefits of the site's inherent water power.
Academic
The shift from direct mechanical water power to electrical generation marked a pivotal moment in the Second Industrial Revolution.
Everyday
The old mill by the river was originally run on water power.
Technical
The turbine's efficiency in converting potential energy to kinetic energy determines the plant's water power coefficient.
Examples
By Part of Speech
adjective
British English
- A water-powered forge was central to the village's economy.
- They restored the water-powered mill.
American English

Examples
By CEFR Level
- Long ago, mills used water power to grind flour.
- The factory was built near the waterfall to use its water power.
- Countries with mountainous terrain often have significant potential for generating electricity from water power.

Learning
Memory Aids
Mnemonic
Imagine a WATER wheel with the POWER to light up a city.
Conceptual Metaphor
WATER IS A WORKFORCE (Harnessing, channeling, tapping into its strength).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque "водная сила". Use "гидроэнергия" or "энергия воды". Distinguish from "мощность воды" which refers to hydraulic pressure or pump power.
Common Mistakes
- Using as a verb (e.g., 'The river water powers the town' is correct; 'The river water powers' as a noun phrase is incorrect). Confusing with 'water pressure'.

FAQ
Frequently Asked Questions
Very closely related. 'Hydroelectric power' is a subset of 'water power', specifically referring to electricity generation. 'Water power' can also refer to the direct mechanical drive of machinery, like in a watermill.
No, the noun phrase itself is not used adjectivally. The correct adjectival form is 'water-powered' (e.g., a water-powered turbine).
No, it is primarily a technical, historical, or environmental term. In everyday talk, people are more likely to say 'hydropower' or specifically 'hydroelectricity'.
Both are renewable energy sources, but 'water power' relies on the gravitational potential energy and flow of water (more predictable, location-specific), while 'wind power' uses kinetic energy from air movement (more variable, less location-restricted).
