powered 30秒で

  • Powered describes how something gets energy to work, like 'solar-powered' or 'battery-powered.'
  • It is also the past tense of 'power,' meaning to provide energy or move with great force.
  • Metaphorically, it describes the motivation or technology behind a system, like 'AI-powered.'
  • Commonly used in tech, engineering, and to describe personal determination (powering through).

The word powered is a versatile term that primarily functions as the past participle of the verb 'power' or as an adjective. At its core, it describes the state of being supplied with energy—whether that energy is electrical, mechanical, chemical, or even metaphorical. When we say a device is powered, we are identifying the source of its animation or functionality. In the modern era, this word has become ubiquitous due to the explosion of technology and the diverse ways we energize our lives. From the solar-powered calculator on a student's desk to the nuclear-powered submarines patrolling the deep oceans, the term defines the relationship between an object and its fuel source. It implies a transition from a state of potentiality to a state of action. Without being powered, a machine is merely a collection of parts; with power, it becomes a tool capable of performing work. This concept extends into the digital realm where we see 'AI-powered' software or 'data-powered' insights, suggesting that the underlying technology or information is what drives the system's intelligence and utility.

Technical Application
In engineering, 'powered' refers to the specific mechanism of energy transfer. For instance, a hydraulic-powered lift uses fluid pressure to move heavy loads, highlighting the physical medium of the energy.
Metaphorical Drive
In business or personal growth, 'powered' describes the motivation or core philosophy behind an action, such as a 'purpose-powered' career path where values provide the momentum.

The entire remote village is now powered by a sustainable microgrid of solar panels and wind turbines.

Furthermore, the word 'powered' carries a sense of force and determination when used as a verb in the past tense. If an athlete 'powered through' the final mile of a marathon, it suggests a significant expenditure of internal energy and willpower to overcome resistance. This dual nature—describing both the source of energy for a machine and the forceful movement of a human—makes it an essential part of the English lexicon. It bridges the gap between the mechanical world and the human experience. We also see it frequently in compound adjectives, which are words joined by a hyphen to describe a noun. Examples include battery-powered, gas-powered, and steam-powered. These compounds are highly efficient because they immediately tell the listener exactly what makes the subject work. In marketing, 'powered' is a high-value word; it suggests strength, reliability, and modern capability. A 'powered' toothbrush sounds more effective than a manual one, and a 'powered' search engine sounds more capable than a basic directory. The word evokes a sense of readiness and active engagement with the world.

She powered up her laptop and began the presentation with confidence.

In historical contexts, the word marks the evolution of human industry. The 'steam-powered' era of the Industrial Revolution changed the world by replacing animal and human labor with the force of pressurized water vapor. Today, we are in the midst of another shift, moving toward 'electrically-powered' transportation systems to reduce carbon emissions. This historical trajectory shows that 'powered' is not just a descriptive word, but a marker of progress and technological change. It encapsulates the human desire to harness the forces of nature to achieve more than we could with our bare hands. Whether we are talking about a 'pedal-powered' bicycle or a 'jet-powered' aircraft, the word 'powered' tells a story of energy conversion and the pursuit of efficiency. It is a word that looks toward the future while acknowledging the fundamental physics of the present.

Environmental Context
The phrase 'renewably powered' is becoming a gold standard for companies aiming to prove their commitment to the planet.

Using the word powered correctly requires an understanding of its grammatical roles as both an adjective and a verb. As an adjective, it frequently appears in compound forms. For example, 'The battery-powered fan kept us cool during the hike.' Here, 'battery-powered' modifies 'fan' to explain its energy source. This structure is very common in technical writing and everyday descriptions of gadgets. When used as a past participle in a passive construction, it often follows the verb 'to be' and is followed by the preposition 'by'. For instance, 'The lighthouse is powered by solar energy.' This tells us the relationship between the subject and the energy source. In more active contexts, 'powered' acts as the past tense of the verb 'to power,' meaning to provide energy or to move with great force. 'The engine powered the massive ship through the rough waves.' In this case, 'powered' is the action being performed by the engine.

Compound Adjectives
Always use a hyphen when 'powered' is part of a compound adjective before a noun: 'a solar-powered house,' but 'the house is solar powered' (hyphen is optional here but common).
Phrasal Verbs
'Power up' and 'Power down' are essential phrasal verbs. 'He powered up the computer' means he turned it on and it began receiving energy.

The new electric vehicle is powered by a high-capacity lithium-ion battery.

Another sophisticated way to use 'powered' is in the context of metaphorical momentum. You might hear someone say, 'The campaign was powered by a grassroots movement of volunteers.' This doesn't mean the volunteers were literally plugging into the campaign with wires; rather, it means their energy, enthusiasm, and work were the driving forces that made the campaign successful. This usage is very common in journalism and political science. Similarly, in the world of software, you will often see the phrase 'Powered by [Company Name]' at the bottom of a website. This indicates that the underlying technology or hosting is provided by that specific company. It is a way of giving credit to the source of the site's functionality. When writing, consider whether you are describing a physical energy source or a metaphorical one, as this will help you choose the right surrounding words.

Despite the heavy rain, the runner powered through the final stretch of the race.

In formal reports, 'powered' is often used to describe infrastructure. 'The facility is powered by a combination of grid electricity and backup diesel generators.' This level of detail is crucial in technical documentation. In creative writing, you might use 'powered' to describe a character's intense movement: 'He powered his way through the crowd, determined to reach the stage.' This creates a vivid image of strength and purpose. Note that 'powered' can also be used in the negative: 'unpowered.' An 'unpowered' site is one without electricity. Understanding these nuances allows you to use the word with precision across different genres of writing, from technical manuals to emotional narratives. Always ensure that the subject of your sentence is the thing being energized or the thing doing the energizing, and the word 'powered' will naturally find its place.

Active vs. Passive
Active: 'The wind powered the mills.' Passive: 'The mills were powered by the wind.' Both are correct, but the active voice is often more dynamic.

You will encounter the word powered in a vast array of real-world contexts, ranging from the mundane to the highly specialized. In the world of consumer electronics, it is perhaps most common. Every time you buy a new gadget, the packaging likely mentions how it is powered—'USB-powered,' 'battery-powered,' or 'AC-powered.' Tech reviewers on YouTube or in magazines constantly use the word to describe the performance and energy requirements of new hardware. They might say, 'This laptop is powered by the latest M2 chip,' which highlights the internal processor as the 'engine' of the device's performance. This usage has become a standard way to discuss the core components of any digital system. In the automotive industry, 'powered' is a key term in the transition to green energy. Car commercials frequently boast about 'electrically-powered' ranges or 'hydrogen-powered' prototypes, signaling a shift away from traditional internal combustion engines.

Marketing & Branding
Look at the bottom of web pages or apps. You'll often see 'Powered by WordPress' or 'Powered by Stripe.' This is a standard way to acknowledge the platform or service provider.
News & Environment
News reports on climate change often discuss 'solar-powered' grids or 'wind-powered' cities, emphasizing the source of energy as a political and environmental choice.

The space station is powered by massive solar arrays that capture energy from the sun.

In the fitness and sports world, 'powered' takes on a more physical and human meaning. Commentators during a football match might say a player 'powered the ball into the back of the net,' describing a shot with immense force. In the gym, you might hear about 'power-powered' movements or 'explosive-powered' training, focusing on the generation of force from the muscles. This linguistic crossover from machines to humans is a testament to the word's ability to convey the concept of energy in all its forms. Furthermore, in the realm of business and leadership, 'powered' is used to describe the underlying motivation of a company. A CEO might claim their company is 'powered by innovation' or 'powered by a commitment to customer service.' This metaphorical use suggests that these abstract concepts are the 'fuel' that keeps the business moving forward and succeeding in a competitive market.

This entire event was powered by the hard work of over two hundred volunteers.

You will also hear 'powered' in the context of household chores and DIY projects. A 'power-powered' drill or a 'gas-powered' lawnmower are common items in many garages. The word helps distinguish these tools from their manual counterparts. In aviation, the term is vital; pilots and engineers talk about 'jet-powered' versus 'propeller-powered' aircraft, which defines the plane's capabilities, speed, and fuel consumption. Even in the kitchen, you might have a 'battery-powered' milk frother. The word is so deeply embedded in our descriptions of the physical world that we often use it without thinking. It serves as a constant reminder of the energy required to sustain our modern lifestyle. Whether it's the 'gravity-powered' clock on the wall or the 'data-powered' algorithm suggesting your next movie, 'powered' is the word that explains the 'how' behind the 'what.'

Science Fiction
In movies and books, you'll hear about 'fusion-powered' starships or 'plasma-powered' weapons, using the word to ground futuristic concepts in the familiar language of energy.

While powered is a common word, there are several pitfalls that learners and even native speakers can fall into. The most frequent mistake is confusing 'powered' with 'powerful.' While they share the same root, they serve different functions. 'Powered' is descriptive of the *source* of energy, whereas 'powerful' is descriptive of the *intensity* or *strength* of that energy. For example, saying 'The car is very powered' is incorrect; you should say 'The car is very powerful' if you mean it has a lot of strength, or 'The car is electrically powered' if you are describing its fuel source. Another common error involves the use of prepositions. Many people mistakenly say 'powered with electricity' instead of the more standard 'powered by electricity.' While 'with' can sometimes be understood, 'by' is the preferred preposition when identifying the energy source in a passive construction.

Powered vs. Powerful
Incorrect: 'This is a powered engine.' (Unless you mean it's currently receiving power). Correct: 'This is a powerful engine.' (It has a lot of strength).
Preposition Errors
Incorrect: 'The boat is powered from the wind.' Correct: 'The boat is powered by the wind.'

Wait, is this device powered by batteries or does it need to be plugged in?

Another area of confusion is the use of hyphens in compound adjectives. As a general rule, when 'powered' follows another word to describe a noun (like 'solar-powered car'), a hyphen should be used. However, if the description comes after the noun (like 'The car is solar powered'), the hyphen is often omitted, though its inclusion is not necessarily wrong. This can be tricky for those aiming for perfect formal writing. Additionally, the verb form 'powered through' is sometimes misused. It should be reserved for situations involving significant effort or force. Using it for a very easy task might sound strange or sarcastic. For example, 'I powered through the task of eating a cookie' sounds like a joke because eating a cookie requires no effort. Reserve 'powered through' for overcoming obstacles, like 'She powered through the difficult exam despite having a headache.'

He powered the boat toward the shore before the storm hit.

Finally, be careful with the passive voice. While 'The device is powered by batteries' is perfectly fine, overusing the passive voice can make your writing feel heavy or bureaucratic. Whenever possible, try to use the active voice: 'Batteries power the device.' This is clearer and more direct. Also, avoid using 'powered' when 'started' or 'turned on' is more appropriate. 'I powered the light' is less natural than 'I turned on the light.' 'Powered' usually implies a continuous supply of energy or a forceful action, not just the simple act of flipping a switch. By paying attention to these small details, you can avoid the most common mistakes and use 'powered' with the confidence of a native speaker. Understanding the distinction between the source of energy and the strength of energy is the key to mastering this word.

Overuse in Marketing
Be wary of the 'AI-powered' buzzword. Often, it is used to make a simple product sound more advanced than it actually is.

Depending on the context, there are several synonyms and alternatives to powered that can add variety and precision to your language. If you are talking about the energy source of a machine, words like fueled, driven, or energized might be appropriate. 'Fueled' is specifically used when a combustible material like gasoline or coal is involved. 'The car is fueled by petrol.' 'Driven' is often used for mechanical systems, such as 'a gear-driven mechanism.' 'Energized' is more common in electrical contexts, referring to a circuit that has been 'made live' or supplied with voltage. Choosing the right word depends on the specific type of energy and the mechanism of its application.

Powered vs. Fueled
Use 'powered' for general energy (electricity, wind, sun). Use 'fueled' specifically for things that burn fuel (gas, wood, food).
Powered vs. Propelled
'Powered' refers to the energy source. 'Propelled' refers to the resulting movement. 'The rocket is powered by liquid oxygen and propelled into space.'

The new startup is fueled by a massive injection of venture capital.

In metaphorical contexts, alternatives like motivated, inspired, or sustained can be very effective. Instead of saying 'The project was powered by her passion,' you might say 'The project was fueled by her passion' or 'The project was driven by her passion.' 'Driven' implies a strong sense of direction and purpose, while 'fueled' suggests that the passion provided the necessary energy to keep going. If you are describing a person moving with force, you could use charged, stormed, or forced. 'He charged through the line' sounds more aggressive than 'He powered through the line.' 'Stormed' suggests a sense of anger or suddenness. Each of these words carries a slightly different emotional weight, so selecting the right one can help you convey the exact tone you want.

The athlete was propelled to victory by the cheering of the crowd.

In technical fields, you might use actuated or triggered. 'Actuated' is used when a component is moved into action by a signal or power source, common in robotics. 'The arm is actuated by a servo motor.' 'Triggered' is used for events that are started by a specific cause. When discussing computers, supported or hosted might be better than 'powered' depending on the relationship. 'The website is hosted on AWS' is more precise than 'The website is powered by AWS' if you are talking about where the files live. However, 'powered by' is still very common for the software itself. By expanding your vocabulary to include these alternatives, you can make your writing more precise and engaging, avoiding the repetition of the same word while still conveying the core idea of energy and action.

Contextual Choice
Use 'actuated' for mechanical parts, 'energized' for electrical circuits, and 'motivated' for human behavior.

powered vs Powerful

Similar root and sound.

Powerful describes strength (a powerful engine). Powered describes the energy source (a gas-powered engine).

The powerful car is gas-powered.

powered vs Fueled

Both describe energy sources.

Fueled specifically implies burning a substance (gas, coal). Powered is more general (electricity, wind).

The stove is fueled by wood, but the light is powered by solar.

powered vs Driven

Both describe the force behind movement.

Driven often refers to the mechanical connection (belt-driven). Powered refers to the energy input.

The belt-driven fan is powered by a motor.

powered vs Energized

Both relate to energy.

Energized is usually technical (an energized wire) or emotional (I feel energized). Powered is more about functionality.

Once the circuit was energized, the machine was powered.

powered vs Propelled

Both relate to movement.

Propelled is the physical act of pushing forward. Powered is the energy that allows it.

The rocket is powered by fuel and propelled by thrust.

Metaphorical Use

Use 'powered by' to describe the motivation behind a project or movement to sound more dynamic.

Power Through

Use the idiom 'power through' to describe finishing a task when you are tired; it sounds very natural to native speakers.

Active Voice

Instead of 'The car is powered by gas,' try 'Gas powers the car' for a more direct and energetic sentence.

Avoid 'Powerful'

Indo-European > Italic > Latin > Romance > English.

よくある質問

10 問

'Powered by' is the standard and most common phrase. 'Powered with' is rarely used and often sounds incorrect.

Use a hyphen if it's before a noun (a solar-powered car). If it's after the noun, it's optional but often omitted (the car is solar powered).

Yes, but usually in the phrase 'power through' (meaning to persist) or metaphorically (he is powered by ambition).

'Powered up' sounds more technical and implies the system is loading or receiving energy. 'Turned on' is more general.

No, we use 'fueled' for food (e.g., 'fueled by a good breakfast').

Yes, it describes something that does not have an energy source, like an unpowered campsite.

It means the software or tool uses Artificial Intelligence to function or provide results.

It's better to say 'I turned on the light' or 'The battery powered the light.' 'I powered' usually implies forceful movement.

It can be both. It's the past participle of the verb 'power' and is often used as an adjective.

A vehicle that moves using only human physical effort, like a bicycle or a rowboat.
