NEW figures show that the amount of energy consumed in Jersey has fallen by almost a third over the past two decades – with liquid fossil fuel consumption reducing by 37% and gas by 64%.
This week, the government published its annual audit of the supply and use of energy in the Island, covering 2025.
Just under three-fifths (57%) of energy consumed in Jersey was liquid fuels, with electricity accounting for two-fifths (40%) and synthetic gas, which is piped through the network having been converted from LPG, making up the remaining 3%.
From 2004 to 2025, Jersey’s total final energy consumption reduced by 29%. Over the five years from 2021 to 2025, the reduction was 7% – comprising a 10% reduction in predominantly fossil liquid fuels and gas, and a 3% reduction in electricity.
Energy consumption last year was the lowest level over that five-year period.
Of total energy used, 37% was for residential use, 34% for transportation (predominantly road) and 29% for commercial, government and agriculture use.
The consumption of petrol and motor diesel continued to reduce in 2025 while the proportion of blended liquid fuels, including biofuels, for road use increased.
The small amount of consumption of vegetable oil and electricity for road also continued to increase.
Liquid fuels accounted for almost three-fifths (59%) of Jersey’s energy supply; electricity (imported and locally generated) accounted for the remainder (41%).
