Wales needs an affordable, reliable and clean energy system now and in the future.

Although our use of renewable energy makes significant and increasing contributions, Wales is still mostly reliant on using imported natural gas.

Generation of electricity from renewable sources, mainly wind and solar, has been steadily increasing over the past 10 years.

The use of bioenergy for renewable electricity and heat is also increasing.

Despite increases in renewable energy generation and use of natural gas to replace coal and other fossil fuels, total emissions from the power sector in Wales has grown by 44% between 1990 and 2016. Over the same period, overall UK emissions of greenhouse gases from the sector reduced by 60%.

What's available now

The pressures, impacts and opportunities for action identified by this cross-cutting theme can be found in the natural resource registers for the ecosystems.

What's coming in March 2021

The full chapter will follow in March 2021.

The chapter will describe the importance of reducing energy consumption and improving energy efficiency across all sectors, whilst increasing renewable energy, to help achieve and ensure sustainable energy supply and demand. This is vital in supporting the resilience of ecosystems. The chapter will also highlight some of the barriers to achieving this. It will describe how policy, technology, behaviour changes and new ways of working could help achieve a sustainable energy system for Wales and the UK.

A description of additional evidence needed for the assessment will also be published.
