The UK's gross electricity production from non-renewable municipal waste is forecasted to rise steadily over the next five years, starting at 17.18 thousand terajoules in 2024, reaching 20.06 thousand terajoules by 2028. This represents a compound annual growth rate (CAGR) of approximately 3.9%. Such growth indicates an increasing reliance on waste-to-energy conversion as part of the UK's energy mix.

Future trends to watch include:

Potential policy shifts towards renewable energy sources which could impact future investments in non-renewable waste energy.
Technological advancements that may improve energy efficiency or reduce dependence on non-renewable waste.
Economic conditions that might influence waste production levels and subsequent energy output.
