hydropower

/ˈhaɪ.droʊˌpaʊ.ɚ/

Hydropower is the generation of electricity using the natural force of flowing water.

30秒でわかる単語

  • Energy produced by moving water.
  • A clean, renewable source of electricity.
  • Often generated using dams and turbines.

Overview

Hydropower, also known as hydroelectric power, is the process of converting the kinetic energy of flowing or falling water into electrical energy. It is one of the oldest and largest sources of renewable energy, playing a critical role in global electricity production by providing a stable and reliable power supply.

Usage Patterns

The word is generally used as an uncountable noun. It is often paired with verbs like 'generate,' 'produce,' or 'harness.' In professional or environmental contexts, it is frequently used to discuss national energy policies, carbon reduction, or infrastructure projects involving dams and turbines.

Common Contexts

You will encounter 'hydropower' in discussions about climate change, sustainable development, and utility management. It is a staple topic in geography, environmental science, and economics classes. News reports often refer to it when discussing the energy mix of a country or the impact of large-scale engineering projects on ecosystems.

Similar Words Comparison

While 'hydropower' specifically refers to electricity generated by water, 'hydroelectric' is the adjective form used to describe the power plants or the energy itself. 'Renewable energy' is a broader umbrella term that includes wind, solar, and geothermal, whereas 'hydropower' is a specific sub-category within that group. Understanding the distinction helps in writing precise reports about energy systems.

よく混同される語

hydropower vs Hydroponics

Hydroponics refers to growing plants in water without soil. It is completely unrelated to energy production.

hydropower vs Hydrology

Hydrology is the study of the movement and distribution of water on Earth. It is a scientific field, not an energy source.

文法パターン

rely on hydropower invest in hydropower generate electricity through hydropower

How to Use It

使い方のコツ

Hydropower is a formal, technical term. It is rarely used in casual conversation unless discussing environmental issues or utility bills. Always use it as a singular, uncountable noun.


よくある間違い

Learners often say 'hydropower energy', which is redundant; 'hydropower' already includes the concept of energy. Another mistake is confusing it with 'hydro' (as in hydro-flask or hydration), which relates to water consumption, not power.

Tips

💡

Use with verbs of production

Collocate hydropower with verbs like 'generate' or 'produce' to sound more natural. For example, say 'The country generates significant electricity through hydropower.'

⚠️

Avoid confusing with water power

While 'water power' is understandable, 'hydropower' is the standard technical term. Use 'hydropower' in academic or professional writing.

🌍

Historical significance of dams

Many countries rely on massive dams for their national grid. Mentioning these projects often highlights the balance between development and nature.

語源

The word comes from the Greek 'hydro,' meaning water, combined with the English word 'power.' It entered common usage in the late 19th century as electrical engineering advanced.

文化的な背景

Hydropower is often associated with large national infrastructure projects like the Hoover Dam in the US or the Three Gorges Dam in China. These structures are often seen as symbols of national technological progress.

覚え方のコツ

Think of 'Hydro' (water) + 'Power' (electricity). It is power from water!

よくある質問

4 問

Yes, they are essentially synonymous. Hydropower is the general term for the energy, while hydroelectric is often used as an adjective to describe the machinery or plants.

Yes, it is classified as a renewable energy source. It is driven by the water cycle, which is constantly replenished by the sun.

It is considered clean because it does not burn fuel to create energy. However, building large dams can impact local ecosystems and fish populations.

Small-scale or micro-hydropower systems can be used for individual homes near a stream. However, it requires specific geographical conditions to be effective.
