Find a wide range of publications that provide energy insight and analysis right here, as well as information about how we're shaping the future of energy in the UK.

Our Future Energy Scenarios (FES) and other publications aim to encourage and inform debate, leading to changes that ensure a secure, sustainable, and affordable energy future.

Against a backdrop of political and technological change, it's impossible to forecast a single energy future over the long term. By providing a range of credible futures in these publications, it allows us to support the development of an energy system that is robust against a range of outcomes.
