No single power synonym covers every case, because power can mean control over people, physical strength, a skill, an official right or the electricity in a wall socket. For control, reach for authority, influence or command. For muscle, use strength or force. For electricity, energy or current.

A ladder of control words
The five chips go from gentle to total. Influence means you can shape what others choose. Authority adds an official basis, such as a job title or a law. Control means you decide what happens. Command suggests giving orders, often in an army or a crisis. Dominance means one side clearly beats every rival.
Use the gentlest word that is accurate. A teacher has authority in class, but calling it dominance would sound threatening.

Power as a verb
When something powers a machine, it supplies the energy. Good replacements are run, drive, fuel and propel.
- Batteries power the clock becomes batteries run the clock.
- Steam powered the early trains becomes steam drove the early trains.
- Coffee powers my mornings becomes coffee fuels my mornings.
Fuel and drive also work in a figurative way: curiosity drives research. Propel suits forward motion, like a rocket or a career.
Formal, casual and informal choices
Formal writing: jurisdiction, mandate and prerogative belong to law and government. Capacity and capability suit science and business reports.
Everyday speech: clout means social or political pull ("she has clout with the council"). Muscle can mean force or the means to act ("the union has the muscle to strike"). Both are informal, so keep them out of an academic paper.
Tech talk: people say juice for battery charge in casual chat. Write charge or battery life in anything official.
Near misses: energy, strength, potential
Energy is not the same as power in physics. Energy is the amount stored, and power is how fast it is used. In everyday prose the two blur, but a science report should keep them apart.
Strength describes what you have; force describes what you apply. A lifter has strength and uses force on the bar. Potential is power not yet used, so it fits plans and talent, not results.

Frequently asked questions
Which word for power fits a leader best?
Authority, if the power comes from a role. Influence, if it comes from respect or personality. Command suits military or emergency leaders.
Is strength a good replacement for power?
Yes, for physical or mental force: the strength of a storm, inner strength. It does not work for official or electrical power.
Power and authority: what is the difference?
Authority is power that others accept as legitimate, like a judge in court. Power can exist without that approval, such as control seized by force.
Which formal nouns can replace power in law?
Jurisdiction, mandate and prerogative. Jurisdiction is about area or subject, mandate about permission from voters, and prerogative about a special right of an office.
Antonyms of power: which one should I use?
Powerlessness for having no control, weakness for low strength, and inability for a missing skill. Pick by the sense of power you are reversing.
Can clout be used in formal writing?
It is informal. In a news story it is fine, but in an essay or report swap it for influence or standing.
