Research background: The world is actively transforming socio-economic and production processes. Ensuring economic growth today is accompanied by an increase in living standards and environmental degradation, the exhaustion of natural resources, imbalance in the biosphere, and climate change, which leads to poor human health and limits the possibilities for further development. All this is due to the need to transform both the provision of technological progress for economic development, and the favouring of the natural environment in the context of globalization. Purpose of the article: The purpose of the article is to study energy conservation as a necessary condition for the development of a “green” economy in the context of globalization and transformation of society. Methods: The research is based on general scientific methods of empirical research (observation, measurement, experiment, modelling), analysis and synthesis, analogy, systematization, as well as methods of structural-logical, statistical analysis. Findings & Value added: The article systematizes approaches to defining the concept of a green economy, reveals the relationship between the categories of politics and society, and elements of the green economy. The efficiency of the use of fuel and energy resources is determined by the energy intensity of GDP. In this regard, the predicted dynamics of energy intensity of GDP by regions of the world, energy consumption per capita in the world and groups of countries are analysed, measures of state support in the field of energy conservation and energy efficiency are substantiated.
