[Copper](https://www.materialinsights.org/commodities/copper/) (commodity) and [Offshore wind](https://www.materialinsights.org/energy/e_offshore_wind/) (energy): 2 relationships.

## How they are linked

### 1. Material need

*Physical flow · Direct · Copper → Offshore wind*

Building or running Offshore wind needs copper.

### 2. Price link: cable input

*Cost and price · Weak · Both ways*

Array and export cables carry power ashore and use a lot of copper, along with aluminium. The turbine proxy shows no monthly link with copper (-0.04), since cable costs are not in the turbine index.
