Try to explain what 水力発電 is to someone who doesn't know Japanese, using only gestures and the English word 'hydroelectric'. Then, try to say the Japanese word and explain its components.
Word Origin
The word 水力発電 is a compound term formed from three kanji: 水 (sui) meaning 'water', 力 (ryoku) meaning 'power' or 'force', and 発電 (hatsuden) meaning 'electricity generation'. This direct combination clearly indicates its meaning.
Original meaning: Water power electricity generation.
Sino-Japanese (Kanji-based compound)Cultural Context
While generally seen as a positive renewable energy source, the construction of large dams for hydroelectric power can have significant environmental and social impacts. These include altering river ecosystems, displacing communities, and affecting fish migration. Discussions about new projects often involve careful environmental impact assessments and public consultations to address these concerns.
In English-speaking countries, the term is 'hydroelectric power generation' or simply 'hydropower'. The concept is universally understood as using water to produce electricity.

Frequently Asked Questions
10 questions水力発電 (suiryoku hatsuden) means 'hydroelectric power generation' or 'hydropower' in English. It refers to the process of generating electricity by using the force of moving or falling water.
Yes, 水力発電 is considered a renewable energy source because it relies on the natural water cycle, which is constantly replenished by rain and snow. As long as there is flowing water, electricity can be generated.
A typical 水力発電 system includes a dam to control water flow, a reservoir to store water, penstocks (pipes) to guide water to turbines, turbines that spin when water flows through them, and generators connected to the turbines to produce electricity.
Yes, while renewable, large-scale 水力発電 projects can have environmental impacts such as altering river ecosystems, affecting fish migration, and displacing communities due to reservoir flooding. There can also be issues with sedimentation and changes in water quality downstream.
水力発電 uses the kinetic and potential energy of water. Solar power uses energy from sunlight, and wind power uses the kinetic energy of wind. All are renewable energy sources but utilize different natural forces.
Sure. 日本は山が多く、水力発電に適した国です。(Nihon wa yama ga ooku, suiryoku hatsuden ni tekishita kuni desu.) This means 'Japan has many mountains and is a country suitable for hydroelectric power generation.'
A hydroelectric power plant is called 水力発電所 (suiryoku hatsudensho).
Yes, 水力発電 is a significant source of electricity in Japan, contributing to its renewable energy mix, although solar and thermal power also play substantial roles.
Yes, the kanji are 水 (sui) for 'water', 力 (ryoku) for 'power' or 'force', and 発電 (hatsuden) for 'electricity generation'. Together, they literally mean 'water power electricity generation'.
Related terms include ダム (damu - dam), 電力 (denryoku - electricity), and 再生可能エネルギー (saisei kanou enerugii - renewable energy).

Break Down the Sound
Practice saying 'sui-ryo-ku ha-tsu-den' slowly and clearly. Focus on the distinct sounds of each syllable. The 'ryoku' part is key for 'power', and 'hatsuden' is for 'electricity generation'.
Kanji Connection
Remember the kanji: 水 (water), 力 (power), 発電 (electricity generation). Visualize water providing power to generate electricity. This visual link will help you recall the meaning.
Context is Key
Suiryoku hatsuden is used when discussing energy sources, infrastructure, and environmental topics. If the conversation is about electricity, but not specifically from water, a simpler term like 電気 (denki) might be more appropriate.
Sentence Structure
It often appears with particles like は (wa) or が (ga) when it's the subject, or を (o) when it's the object of an action like 'developing' or 'promoting'.
Example
あのダムは水力発電所として利用されている。
