This publication is authored by the Energy Data Centre (EDC) of the International Energy Agency (IEA) and released in October 2020. The paper explores the role of new and digital technologies for energy end-use data collection. It reviews applications, strengths, and weaknesses of the major existing technologies, dividing them into three broader categories based on whether the purpose is data collection, data management, or data analysis. The case studies and analysis provided may serve as a starting point for energy statisticians and energy efficiency experts in guiding the design, and/or informing the implementation of new technologies for data collection.
