In 2023, the non-renewable municipal waste energy supply in the UK was approximately 61.2 thousand terajoules. Forecasted data from 2024 to 2028 shows a consistent upward trend, with an increase from 63.8 in 2024 to 74.17 thousand terajoules in 2028. This reflects an average annual growth of approximately 3.7%. Year-on-year variations display a steady rise, with each year witnessing a roughly similar percentage increase of around 3.5% to 3.8%. This suggests a growing reliance on non-renewable municipal waste energy sources.

Future trends to watch for:

Government policies focusing on sustainability could impact the projections, potentially reducing reliance on non-renewable sources.
Technological advancements in waste-to-energy conversion may enhance efficiency and influence supply quantity.
Public and private sector investment trends in renewable energies might pivot focus away from non-renewable waste energy.
