Assessment of the Energy System of Ukraine: Ways of Recovery, Cases of Development

The economy of Ukraine is partially destroyed and poses an energy threat to European countries. The article analyzes trends in the development of consumption in Ukraine, and assesses the prospects for development. Energy Ukraine's system depends on fossil fuels. The government sought to diversify risks and ensure sustainable development. The energy consumption market is characterized by a decline and an increase in the use of gas. The article develops cases for making decisions on the necessary investments in the energy system of Ukraine after the war. We analyze energy consumption trends and justify the need for investment in the nuclear industry, which occupies a large part of the country's energy consumption. A model for assessing and forecasting the energy consumption market has been developed. The model shows an upward trend in oil and gas consumption. Our approach allows us to quantify the net increase in energy consumption in the future.  Keywords: energy, energy supply, renewable energy, energy strategy, energy resources
