Energy & Water

The University of South Wales is committed to reducing its environmental impact through reducing energy and water consumption and investing in energy efficient products. 

Energy usage is a critical area within sustainability, giving everyone the opportunity to contribute to minimising our negative impacts.


100% of our electricity is procured from renewable sources. Green gas is an area of significant interest for future investigation.


At present USW has solar arrays on five University buildings.

In the summer of 2020, a 100 kW solar photovoltaic array was installed on Treforest Sports centre roof. This adds to PV arrays on Pen Y Fan halls of residence roof Sports Park 2 building, saving a significant amount of emission.

We also have solar thermal arrays on Treforest Students Union and Sports Park 1, which saves over 6 tonnes of carbon dioxide emissions annually.


The University has a comprehensive network of submetering across all sites. Monitoring is critical to minimising energy wastage and helping us use our resources in the most efficient way possible.
