[Coal mining](https://www.materialinsights.org/energy/e_coal_mining/) (energy) and [Coal transport](https://www.materialinsights.org/energy/e_coal_transport/) (energy): 2 relationships.

## How they are linked

### 1. Energy flow

*Physical flow · 100% of flow · Coal mining → Coal transport*

Mined coal is loaded onto trains, ships and conveyors.

- **100%** of Coal mining's energy goes this way

### 2. Price link: delivery cost

*Cost and price · Moderate · Both ways*

Rail carries most coal from mine to power station in India and the US, and freight is often a large part of delivered cost. The US rail index and the coal index correlate at 0.16 monthly and 0.50 yearly.

- **0.16** monthly change correlation
- **0.50** 12-month change correlation
- **1.26** fitted elasticity
