The government-published Jersey Energy Trends 2025 report shows that, from 2021 to last year, the Island’s total energy consumption reduced by 7% – comprising a 10% reduction in predominantly-fossil liquid fuels and gas, and a 3% reduction in electricity.

1.27 tonnes – the amount of energy consumed per head of population (based on the ‘oil equivalent’ metric)
1.84 tonnes – the estimated per capita energy consumption in the UK
57% – the percentage of energy consumption attributable to liquid fuels in 2025
29% – the decrease in total energy consumption in Jersey between 2004 and 2025
37% – the decrease in liquid fuel use between 2004 and 2025. In the last five years, from 2021 to 2025, the reduction has been 9%.
