The full publication presents a more detailed analysis of how various factors have shaped energyuse patterns and CO2 emissions since 1973. The analysis draws on a newly developed databasewith detailed information on energy use in the manufacturing, household, service and transportsectors. The database represents the most disaggregated information available on a consistentbasis across countries and sectors. The study uses quantitative measures to illustrate the forcesthat drive or restrain energy use. These measures – or indicators – include: activities such asmanufacturing output or heated-floor-area of homes; structural developments such as changes in manufacturing output mix or changes in the mix of transport modes; and energy intensities for sub-sectors and end-uses. Energy intensity is defined as energy per unit activity, representing the energy used to produce some output or provide a service. At a disaggregated level, changes in this indicator are closely related to changes in energy efficiency.
