The Energy Statistics Pocketbook 2018 presents a compilation of energy statistics designed to highlight the availability of data on various aspects of energy production, transformation and use and its linkages to other key statistics, covering the whole world in the period 1990-2015. It distinguishes itself from the other three UNSD energy statistics annual data publications (Energy Statistics Yearbook, Energy Balances, and Electricity Profiles) in that it highlights key indicators and uses different visualizations (such as maps and charts) to also show developments, dependencies and distributions in a way that standard data tables cannot convey. Energy is central to the achievement of the 2030 Agenda for Sustainable Development and the Paris Agreement on climate change, and sound energy statistics is the basis for the reliable measurement of progress, thereby assisting the formulation of policy measures to achieve international and national sustainable development goals.The information in this publication is primarily based on the energy data collection carried out by the Industrial and Energy Statistics Section of the United Nations Statistics Division (UNSD).
