Dla Ukrainy szczególnie istotne jest bezpieczeństwo energetyczne, którego element stanowi niezależność energetyczna. Jednymi z głównych odbiorców gazu ziemnego w tym kraju są przedsiębiorstwa produkujące energię cieplną i świadczące usługi dostarczania ciepła systemowego dla mieszkańców, organizacji budżetowych i przedsiębiorstw komunalnych. Odpady komunalne można wykorzystać jako alternatywne paliwo znajdujące się w pobliżu zarówno producentów energii cieplnej, jak i odbiorców usług centralnego ogrzewania. Włączenie odpadów komunalnych i paliw z nich do bilansu energetycznego miast zwiększa ich niezależność energetyczną.

Carbon neutrality is necessary to address the global problem of climate change. The International Energy Agency has recognized coal as the largest source of anthropogenic carbon dioxide emissions. This article analyzes carbon dioxide emissions from coal and carbon dioxide emissions from energy for the major emitters of CO2 emissions. As more than half of the world's Carbon dioxide emissions from coal come from China, the authors have analyzed the extreme situation that could arise in the carbon reduction market if China were to postpone its commitments to reduce coal consumption. The article calculates the time frame required for other coal-consuming countries to phase out coal to compensate for China's annual coal consumption. It demonstrates that without China transitioning from coal consumption to zero-carbon energy sources, other countries will not be able to achieve carbon neutrality by 2050. This proves that for the first time in history, the achievement of the goal set by the global community depends on the actions of a single country. The article outlines the goals set by China in its Nationally Determined Contribution and other government documents to reduce greenhouse gas emissions and achieve carbon neutrality. It also presents China's efforts to implement renewable energy sources, nuclear reactors, and energy storage.

The relevance of the work is determined by the war of the Russian Federation in Ukraine and the decision of the leading countries of the world, the EU and Ukraine to abandon energy dependence on energy from the Russian Federation. An analysis is provided of the main directions for reducing the European Union's dependence on Russian natural gas by a third by the end of 2022, in particular, the development of the Waste-to-Energy market in the EU and other leading countries of the world. The main ways are presented and computational investigations of the possibility of substitution of certain amounts of natural gas with artificial fuel from residual MSW are carried out. Based on the performed calculations, the authors formulated proposals for the feasibility of constructing facilities for energy use of residual MSW in different regions of Ukraine, as well as connecting them to the systems of centralized heating in Ukraine. The paper proves the necessity of building Waste-to-Energy power plants in the largest, large and big cities of the country. The ecological expediency of recovery of residual waste is shown.
