In the UK, fossil energy consumption in international aviation is projected to rise from 145.96 thousand gigawatt-hours in 2024 to 150.43 thousand gigawatt-hours by 2028. Comparing the year-on-year data for 2024 onwards, the growth in consumption is gradual, with an average compound annual growth rate (CAGR) of just under 0.7%.

Considering that 2023 saw fossil energy consumption at 145.96 thousand gigawatt-hours, the forecasted and consistent increase indicates a steady trajectory driven possibly by aviation demand and moderate advancements in fuel efficiency.

Future trends to watch for:

Development and adoption of sustainable aviation fuels could impact fossil energy demands.
Regulatory changes targeting emissions reductions may alter consumption patterns.
Technological innovations could influence energy efficiency and aviation growth rates.
