## Emergence
**Emerges from:** [matter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-matter.substance), [energy](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-energy.capacity), [structure](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-structure.arrangement), [products](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-products.goods), [use](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-use.application)

**Through:** the matter.substance and energy.capacity interact in a structure that can be used

**Novel properties:**
- sustained energy release
- metabolic usability
- organizational stability

## Examples
- A potato provides 77 kcal per 100g, fueling cellular respiration in humans. *(biology)*
- The 1973 oil crisis triggered energy rationing, revealing food's dependence on fossil-fuel-powered agriculture. *(economics)*
- The Mars Curiosity rover's radioisotope thermoelectric generator converts plutonium decay into electricity, sustaining instrument operation. *(engineering)*
