At the A1 level, '재생가능하다' is a very difficult word. It is much longer and more complex than basic words like '먹다' (to eat) or '가다' (to go). However, you can understand it by looking at its parts. '재' means 'again', '생' means 'life', and '가능하다' means 'can do'. So, it means 'can live again'. Think of it as something that doesn't disappear. For example, the sun comes up every day, so solar energy is '재생가능하다'. At this level, don't worry about using it in complex sentences. Just remember that it is a good word for things like the sun, wind, and water that we use for power. You might see it in simple science books or on posters about saving the earth. It is an adjective, so it describes a thing. If you want to say 'renewable energy', you say '재생가능한 에너지'. It is a formal word, so you will hear it in news or school, but not usually when talking to friends about dinner.
At the A2 level, you are starting to learn more about the world around you in Korean. '재생가능하다' is an important word for talking about nature and the environment. It is an adjective that means 'renewable'. You can use it to describe things that nature gives us back, like wind (바람) or sunlight (햇빛). The most important thing to learn at this level is how to change the word to describe a noun. You change '재생가능하다' to '재생가능한'. For example, '재생가능한 에너지' means 'renewable energy'. You might also hear this word in simple news clips about the environment. Try to remember it as a 'green' word. When you talk about helping the earth, you can use this word. It's a bit long, but if you break it down into 'jae-saeng-gan-eung-hada', it becomes easier to say. It is mostly used in serious or helpful contexts, like explaining why we should use solar power.
As a B1 learner, you should be able to use '재생가능하다' in basic discussions about social issues or the environment. This word is a key part of the 'green energy' vocabulary. You should understand that it specifically refers to resources that are naturally replenished. For example, when comparing coal (석탄) and solar power (태양광), you can say '태양광은 재생가능하지만 석탄은 아닙니다' (Solar power is renewable, but coal is not). You should also be comfortable with the different forms: '재생가능한' (attributive) and '재생가능해요' (polite ending). At this level, you might encounter it in reading passages about technology or global warming. It is often paired with words like '자원' (resource) or '발전' (power generation). Understanding this word helps you participate in intermediate-level conversations about the future of our planet and the choices we make as consumers.
At the B2 level, you are expected to use '재생가능하다' fluently in academic or professional contexts. This is a core word for this level because it deals with abstract and technical concepts. You should understand the nuance between '재생가능하다' (renewable) and '재활용 가능하다' (recyclable). A B2 speaker should be able to explain why a certain energy policy is beneficial using this term. For example, you might discuss '재생가능 에너지의 비중을 높여야 합니다' (We must increase the proportion of renewable energy). You will see this word in complex news articles, economic reports about ESG management, and environmental documentaries. You should also be aware of related terms like '신재생 에너지' (new and renewable energy) which is the official term used by the Korean government. At this level, you should be able to use the word in various grammatical structures, such as '재생가능하기 때문에' (because it is renewable) or '재생가능하다고 생각합니다' (I think it is renewable).
For C1 learners, '재생가능하다' is a foundational term used to build more complex arguments. You should be able to discuss the socio-economic implications of transitioning to a '재생가능한 사회' (renewable society). At this level, the word is not just a vocabulary item but a tool for debating policy, ethics, and global trends. You should be familiar with its usage in high-level discourse, such as the 'RE100' initiative or the 'Paris Agreement' (파리 협정). You should also understand the word's etymological roots in Hanja (再生可能) and how this affects its meaning in different contexts, such as biological regeneration versus environmental resources. You can use it to critique current energy systems or to propose innovative solutions for sustainability. Your usage should be precise, distinguishing it clearly from '지속 가능하다' (sustainable) or '친환경적이다' (eco-friendly) while acknowledging how these concepts intersect in modern Korean thought.
At the C2 level, you possess a native-like command of '재생가능하다'. You can use it with subtle nuances in highly specialized fields like environmental law, energy engineering, or philosophical ethics. You understand that while the word is primarily technical, it also carries a weight of 'restoration' and 'hope' in certain literary or rhetorical contexts. You can analyze how the term '재생가능' has evolved in the Korean public consciousness over the last few decades, moving from a niche scientific term to a central pillar of national policy. You are comfortable using it in formal speeches, academic thesis writing, or high-level negotiations. You can also identify and use its antonyms or related technical jargon like '간헐성' (intermittency - a common problem discussed with renewable energy) fluently. Your understanding of the word is holistic, encompassing its linguistic structure, its scientific definition, and its profound cultural and political significance in contemporary South Korea.

재생가능하다 in 30 Seconds

  • 재생가능하다 means 'renewable', referring to resources like solar or wind that naturally replenish.
  • It is a B2-level adjective composed of Hanja roots meaning 'again', 'life', and 'possible'.
  • Commonly used in environmental contexts, especially with the word 'energy' (재생가능 에너지).
  • Distinguish it from 'recyclable' (재활용 가능), which applies to waste like plastic.

The Korean word 재생가능하다 (jaesaengganeunghada) is a sophisticated adjective primarily used in environmental, scientific, and economic contexts. At its core, it describes something that can be restored, recovered, or naturally replenished. The word is a compound of three distinct parts: 재 (jae) meaning 'again' or 're-', 생 (saeng) meaning 'life' or 'birth', and 가능하다 (ganeunghada) meaning 'to be possible'. Together, they literally translate to 'the possibility of being born again' or 'capable of regeneration'. In modern discourse, this term is almost synonymous with the English word 'renewable', particularly when discussing energy sources like solar, wind, and hydroelectric power. Unlike finite resources such as coal or petroleum, which are depleted upon use, renewable resources are characterized by their ability to maintain a constant supply through natural cycles. This word is essential for anyone reaching the B2 level of Korean proficiency, as it appears frequently in news reports, academic papers, and discussions regarding climate change and sustainable development.

Etymological Breakdown
The Hanja roots are 再 (재 - again), 生 (생 - life), and 可能 (가능 - possibility). This structure reflects a logical progression: the ability for a resource to come back to life repeatedly.
Environmental Context
It is most commonly paired with '에너지' (energy) to form '재생가능 에너지' (renewable energy), a key term in global environmental policy and the RE100 initiative.

태양광과 풍력은 대표적인 재생가능한 에너지원입니다. (Solar and wind power are representative renewable energy sources.)

Beyond energy, the term can also apply to materials or processes that allow for restoration. For instance, in biological contexts, it might refer to tissues that are 'regenerative'. However, learners should be careful not to confuse it with '재활용 가능하다' (recyclable), which refers to processing waste into new materials. While a 'renewable' resource like sunlight is naturally replaced, a 'recyclable' resource like plastic requires human intervention to be reused. Understanding this distinction is vital for precise communication in Korean. As South Korea moves toward a 'Green New Deal' and carbon neutrality, the frequency of this word in public life has surged, making it a cornerstone of contemporary Korean vocabulary.

지속 가능한 발전을 위해서는 재생가능한 자원의 활용이 필수적입니다. (The use of renewable resources is essential for sustainable development.)

Using 재생가능하다 correctly requires an understanding of Korean adjective conjugation. As a descriptive verb (adjective), it functions similarly to '예쁘다' or '크다'. When it modifies a noun directly, it takes the form 재생가능한 (jaesaengganeunghan). For example, '재생가능한 에너지' (renewable energy). When it ends a sentence in a polite formal manner, it becomes 재생가능합니다 (jaesaengganeunghamnida), and in a polite informal manner, it is 재생가능해요 (jaesaengganeunghae-yo).

Attributive Form
재생가능한 + Noun (e.g., 재생가능한 자원 - renewable resources). This is the most common way you will see the word in titles and technical descriptions.
Predicative Form
Subject + 이/가 + 재생가능하다. (e.g., 이 에너지는 재생가능하다 - This energy is renewable). This form is used to make a statement about the properties of a subject.

우리 회사는 100% 재생가능한 전력만을 사용하기로 약속했습니다. (Our company has promised to use only 100% renewable electricity.)

One interesting aspect of this word is its flexibility in formal writing. In reports, you might see it used as a noun phrase '재생 가능' (renewable possibility) without the '하다' suffix. For instance, '재생 가능 에너지' is often written with a space, treating '재생 가능' as a compound noun modifying '에너지'. However, grammatically, '재생가능하다' as an adjective is the standard way to describe the state of being renewable. When discussing the future, you might use the form 재생가능해질 것이다 (will become renewable) to indicate a transition in technology or policy. For example, '미래에는 모든 교통수단이 재생가능한 동력을 사용할 것입니다' (In the future, all means of transportation will use renewable power).

이 방식이 정말로 재생가능한지 다시 한번 검토해 봅시다. (Let's review once more whether this method is truly renewable.)

In South Korea, 재생가능하다 is a word that has moved from the laboratory and academic journals into the living room. You will hear it most frequently on the 8 o'clock news during segments on the environment or the economy. With the global push for the 'RE100' (Renewable Electricity 100%) initiative, Korean conglomerates like Samsung and SK are frequently in the headlines discussing their transition to renewable energy. Consequently, terms like '재생가능 에너지로의 전환' (transition to renewable energy) have become common parlance in business circles.

News & Media
Reporters often use this word when discussing government policies aimed at reducing carbon emissions or increasing the share of solar and wind power in the national grid.
Education
Students learn this word early in science and social studies classes when studying the difference between fossil fuels and clean energy.

정부는 2050년까지 재생가능한 에너지 비중을 대폭 확대할 계획입니다. (The government plans to significantly expand the share of renewable energy by 2050.)

You might also encounter this word in corporate social responsibility (CSR) reports. Many Korean companies now emphasize their commitment to '재생가능한 경영' (renewable management) or '재생가능한 소재' (renewable materials) in their packaging. If you visit an eco-friendly exhibition or a science museum in Seoul, such as the Gwacheon National Science Museum, you will see '재생가능하다' plastered across exhibits explaining how solar panels and wind turbines function. In everyday conversation, while it might be too formal for a casual chat about the weather, it is perfectly appropriate when discussing social issues or your personal values regarding the environment with friends or colleagues.

제주도는 재생가능한 에너지 자립을 목표로 하고 있습니다. (Jeju Island aims for renewable energy independence.)

The most frequent mistake learners make with 재생가능하다 is confusing it with 재활용 가능하다 (jaehwallyong ganeunghada), which means 'recyclable'. While both words relate to environmental friendliness, they describe fundamentally different processes. 'Renewable' (재생가능) refers to resources that replenish themselves naturally, like wind or water. 'Recyclable' (재활용 가능) refers to man-made waste like plastic bottles or paper that can be processed and used again. Calling solar energy '재활용 가능하다' would sound very strange to a native speaker.

Confusion with '지속 가능하다'
Another common mix-up is with '지속 가능하다' (sustainable). While related, 'sustainable' is a broader term encompassing economic and social stability, whereas 'renewable' is specifically about the replenishment of physical resources.
Incorrect Particles
Learners often forget that '재생가능하다' is an adjective. They might try to use it as a verb with an object, which is incorrect. You cannot 'renewable something'; something 'is renewable'.

X 플라스틱은 재생가능한 자원입니다. (Plastic is a renewable resource.)
O 플라스틱은 재활용 가능한 자원입니다. (Plastic is a recyclable resource.)

Another subtle mistake involves the spacing. While '재생가능하다' is a single adjective, in many official documents, you will see '재생 가능 에너지'. Here, '재생 가능' functions as a noun phrase. Learners often struggle with whether to attach '하다' or not. A good rule of thumb: if you are describing a noun (e.g., 'renewable energy'), use '재생가능한'. If you are stating a fact about a subject (e.g., 'This is renewable'), use '재생가능하다'. Avoid using '다시 생길 수 있다' as a direct substitute in formal contexts; while it means 'can be born again', it lacks the technical precision of '재생가능하다'.

X 바람은 재활용 가능해요. (Wind is recyclable.)
O 바람은 재생가능해요. (Wind is renewable.)

When discussing topics related to 재생가능하다, you will encounter several related terms that offer different nuances. Choosing the right one depends on whether you are talking about the environment, business sustainability, or the physical process of recycling. Understanding these synonyms and near-synonyms will help you sound more natural and precise in Korean.

지속 가능하다 (jisok ganeunghada)
Meaning 'sustainable'. This is the most common companion to '재생가능하다'. While 'renewable' focuses on the resource itself, 'sustainable' focuses on the ability to maintain a process or system indefinitely without harm. Example: '지속 가능한 개발' (sustainable development).
친환경적이다 (chinhwangyeongjeogida)
Meaning 'eco-friendly' or 'environmentally friendly'. This is a broader, more general term. Renewable energy is always eco-friendly, but not everything eco-friendly is necessarily renewable (like a reusable bag).
고갈되지 않다 (gogaldoeji anta)
Meaning 'to not be depleted'. This is a more descriptive way to explain the concept of being renewable. You might use this in a speech to emphasize that a resource will never run out.

우리는 지속 가능한 미래를 위해 재생가능한 에너지를 선택해야 합니다. (We must choose renewable energy for a sustainable future.)

In technical fields, you might also hear 신재생 (sinjaesaeng), which is a combination of '신' (new) and '재생' (renewable). In South Korea, the government often uses the term '신재생 에너지' to refer to both 'new energy' (like hydrogen fuel cells) and 'renewable energy' (like solar and wind). If you are reading official policy documents, '신재생' is the term you will see most often. Conversely, if you want to express the opposite of renewable, you would use 비재생 (bijaisaeng) or 고갈성 (gogalseong), meaning 'non-renewable' or 'depletable'. Knowing these pairings allows you to construct balanced arguments and understand the full spectrum of environmental terminology in Korean.

석탄은 비재생 에너지원이지만, 태양광은 무한한 재생가능 자원입니다. (Coal is a non-renewable energy source, but solar power is an infinite renewable resource.)

Tips

Pair with '에너지'

The most common usage is '재생가능 에너지'. Memorize this as a single block of meaning to use it quickly in conversation.

Check the Spacing

Technically, '재생가능하다' is one word, but '재생 가능 에너지' is often written with a space. Both are generally accepted in modern writing.

Renewable vs Recyclable

Always remember: Sun = 재생가능 (Renewable). Plastic bottle = 재활용 (Recyclable). Don't swap them!

Learn Hanja

Learning 'Jae' (再 - again) and 'Saeng' (生 - life) will help you understand dozens of other Korean words like '재개발' and '생물'.

Slow Down

Because it's a six-syllable word, take your time. JAE-SAENG-GAN-EUNG-HA-DA. Clarity is better than speed.

Context Clues

If you hear '환경' (environment) or '태양' (sun), expect to hear '재생가능' shortly after.

Formal Endings

In reports, use '재생가능함' or '재생가능함.' as a bullet point to sound concise and professional.

Global Issues

This is a great word for the TOPIK exam, especially for the writing section (Task 54) about global warming or the environment.

Re-Life-Able

Think of it as 'Re-Life-Able'. Re (Jae) + Life (Saeng) + Able (Ganeung). It's a perfect literal translation.

Impress Others

Using this word correctly in a discussion about the news will instantly make your Korean sound more advanced.

Memorize It

Mnemonic

JAE (Again) + SAENG (Life) + GANEUNG (Possible) + HADA (To be). It is POSSIBLE for LIFE to happen AGAIN.

Visual Association

Imagine a green circular arrow (the symbol for recycling/renewal) with a sun inside it.

Word Web

Sunlight Wind Water Again Life Possible Green Clean

Challenge

Try to find three things in your house that are '재생가능하다' or use '재생가능한' energy.

Word Origin

Derived from Sino-Korean roots (Hanja).

Original meaning: The ability for something to be born again or restored.

Sino-Korean (Chinese character based).

Cultural Context

No specific sensitivities, but be careful not to greenwash (using the term for things that aren't actually renewable).

Directly equivalent to 'renewable', but in English, we often just say 'renewables' as a noun, whereas Korean usually adds 'energy' or 'resource'.
