The purpose of this scientific research is to develop and test a methodological approach to a comprehensive environmental analysis of energy technologies, since any implemented energy technology is accompanied by a violation of the ecological balance in nature. The problem of developing a new methodological approach is to more fully represent the possible impact on this violation in order to determine the most environmentally friendly alternative for its further implementation. The article summarizes domestic and foreign experience in creating similar methodological approaches and proposes the development of a new method for a comprehensive comparison of energy technologies, including the formation and calculation of environmental criteria that characterize the impact of energy technologies on the environment. The developed methodological approach is presented in the form of a diagram and consists of three stages: information support, criteria-based assessment of energy technologies and their comparative analysis and ranking using multi-criteria analysis methods. For this purpose, tasks are structurized, energy-environmental criteria are formed and their functional analysis is carried out. The main feature of the methodological approach is a systematic comparison of energy technologies throughout the life cycle of their existence. The article discusses two energy technologies, a traditional CHP burning coal and a wind power plant with electric boilers at the level of production, operation and disposal of their main equipment. Energy technologies are compared using the linear convolution method, which has the advantage that it requires a minimum amount of input from the user, and the output is easily visualized. The studies are of an enlarged nature and were carried out in order to demonstrate the efficiency of the technique.
