The article examines the problems and prospects of modernization of the heating system in Uzbekistan in the context of the transition to a green economy. The authors analysed the current state of the heating system and proposed solutions aimed at increasing its efficiency through the introduction of innovative green technologies, such as solar collectors and other renewable energy sources. The study substantiates the need to use energy-saving technologies and improve the energy efficiency of buildings to reduce the consumption of fossil fuels and lower greenhouse gas emissions. Calculations of the economic efficiency of the proposed measures, including an assessment of the return on investment, are carried out. Recommendations are given for the development and support of green technologies in the heating sector at the state level.
