The trends of global temperature increase in the world due to excessive burning of fossil hydrocarbons are given. Excessive extraction and burning of fossil fuels (hard coal, petroleum products, natural gas) have led to an increase in their cost and climate change. About 40% of CO2 emissions today come from burning coal, 33% from oil refining products, and 22% from natural gas. An increase in CO2 content in the atmosphere leads to a drop in the Earth's surface temperature. At the global level, the world community has adopted three main international agreements on climate change: the UN Framework Convention on Climate Change (1992); Kyoto Protocol (1997); Paris Agreement (2015). More than 190 countries have signed the Paris Agreement. Its main goals are to achieve carbon neutrality by 2050 and to keep the increase in the global average temperature below 2°C by 2100, preferably to 1.5°C. The construction industry is responsible for consumption of up to 40% of all energy. which are used in economies countries of the world In the summarized reports of experts at the 27th UN Conference on Climate Change (COP27), which took place in 2022  year in Egypt (Sharm el-Sheikh) it was stated that in 2022 1% more CO2 will be released into the atmosphere than in in 2021. The main volumes of greenhouse gas emissions come from the burning of fossil fuels. Brought comparative analysis of CO2 emissions when burning different types of fuel. The dynamics of the production of fossil fuels - hard coal, oil and natural gas - is studied, which indicates a significant decrease in their production and consumption. Modern approaches to the growth of RES volumes are considered, the dynamics of the growth of SPP capacities are given. On the basis of European experience, the prospects for the installation of balcony mini SPPs are shown. Individual heating systems and decentralization of engineering systems for providing housing help to increase their stability in adverse conditions. The organizational features of the transfer of the housing stock from a centralized heating system to individual electric and gas heating are revealed. Based on the analysis of the European experience of maintaining the housing stock, the main directions for reducing energy consumption and greenhouse gas emissions of the existing housing stock are given.

As of 2021, Ukraine has an extremely difficult situation with the energy supply of the economy and the heating season. Ukraine is losing several times more energy per unit of living space than other European countries with similar climatic conditions. The amount of energy losses during its production, transportation and operation of the building are reflected in the utility tariffs of consumers. We have large energy losses during its transportation (it's about 30-60%). A targeted state program for the renovation of heating networks with the involvement of local budgets should be developed. The mass reconstruction of boilers and heating networks in the framework of the project "Improving the energy efficiency of district heating of Ukraine" for loans from local budgets and borrowed funds from international financial institutions is relevant. The use of preliminary isolated pipes gives a number of advantages, such as: reduction of heat losses in networks, reduction of costs for repairing outdated and ineffective heating networks of centralized heat suppl.
