The document discusses the UK's energy consumption balance (CBA) and its sources. After the 2008 recession, energy extracted to satisfy UK consumption decreased significantly. There are key differences in the breakdown and attribution of energy at different stages of the energy conversion chain. Calculations show that a 50% improvement in efficiency could reduce the UK's energy CBA by 10.3%, with the mining sector being a primary source of extracted energy that is first allocated along supply chains and between different sectors.

1. Share of energy in the UK energy CBA
 After the 2008 recession, energy extracted to satisfy UK consumption decreased maximum
 Different distribution of energy → energy-extraction CBA → mining sector key source
 First supply-chain ↔ Energy-extracted CBA ↔ Allocation of energy-used
 Energy-used vector required complex allocation of energy between sectors
Energy CBA: comparison energy extension vectors
