[Engine exhaust recovery](https://www.materialinsights.org/energy/e_engine_recovery/) (energy) and [Ship propulsion](https://www.materialinsights.org/energy/e_marine/) (energy): 2 relationships.

## How they are linked

### 1. Energy flow

*Physical flow · 95% of flow · Ship propulsion → Engine exhaust recovery*

Large marine engines use turbochargers.

- **95%** of Ship propulsion's energy goes this way

### 2. Energy flow

*Physical flow · 15% of flow · Engine exhaust recovery → Ship propulsion*

Turbocharging improves ship engine efficiency.

- **15%** of Engine exhaust recovery's energy goes this way
