This book focuses on the link between changing structure of the Indian economy and energy use, which is of immense importance in view of the possible substitutions across different fuel types, within industries and processes, to cleaner fuels which are efficient or less emitting. The book analyses various aspects related to energy use such as the changing sectoral interdependence of energy sectors in the economy, sources of changes in energy use over time, and the implications in terms of changing basket of goods and services traded by India, internationally. Through an application based approach, by using tools for economic analysis to study energy related issues, the book studies the impact of policy reforms using the transaction flows across sectors in an economy-wide framework.
