# Underground, submarine and superconducting cables: Relationships

Source page: https://www.materialinsights.org/energy/e_cables/links/

Every element and industry that Underground, submarine and superconducting cables is linked to, and how. Each pair has its own card explaining the relationships between the two.

- [Aluminium](https://www.materialinsights.org/links/aluminium-and-underground-submarine-and-superconducting-cables/): Buried and subsea power cables need a metal conductor, and aluminium competes with copper for it: aluminium needs a larger cross-section for the same rating but is far lighter and usually much cheaper, so the copper to aluminium price gap decides the choice for many projects. *(researched)*
- [Offshore wind](https://www.materialinsights.org/links/offshore-wind-and-underground-submarine-and-superconducting-cables/): Every megawatt-hour from an offshore wind farm reaches land through subsea export cables, so a few cable makers with factories booked into the late 2020s, and the risk of a single cable fault, set how fast and how reliably offshore wind can grow. *(researched)*
