[Generators and alternators](https://www.materialinsights.org/energy/e_generators/) (energy) and [Internal combustion engines and gensets](https://www.materialinsights.org/energy/e_engines/) (energy): 2 relationships.

## How they are linked

### 1. Energy flow

*Physical flow · 1.3% of flow · Internal combustion engines and gensets → Generators and alternators*

Diesel and gas engines turn gensets.

- **1.3%** of Internal combustion engines and gensets's energy goes this way

### 2. Price link: combined product

*Cost and price · Strong · Both ways*

Diesel and gas gensets pair an engine with a generator, and both are made by similar machinery firms. Monthly moves correlate at 0.30, and yearly moves more strongly, reflecting shared US manufacturing costs and the same industrial demand cycle.

- **0.30** monthly change correlation
- **0.73** 12-month change correlation
- **0.51** fitted elasticity
