# power (energy)

the capacity to produce change through movement in space over time

- Computed level: L19 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: everyday  ·  Arena: power

## Emergence
**Emerges from:** [energy](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-energy.capacity), [time](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-time.dimension), [space](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-space.extent), [motion](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-motion.movement), [change](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-change.process), [effort](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-effort.general), [work](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-work.effort), [process](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-process.general), [make](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-make.verb), [capacity](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-capacity.size), [potential](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-potential.capacity)

**Through:** energy.capacity moves across.space.extent during time.dimension, enabling effort.general that results in work.effort and sustained change.process

**Novel properties:**
- directed capacity for transformation
- spatiotemporal leverage
- sustained agency

## Examples
- The Hoover Dam generates 4.2 billion kilowatt-hours annually by harnessing the Colorado River’s flow through turbines. *(engineering)*
- A cheetah accelerates from 0 to 60 mph in under three seconds, converting metabolic energy into motion. *(biology)*
- The 2021 Texas power grid failure left 4.5 million homes without electricity during a winter storm. *(institutions)*
