The main problem: This article is devoted to the key problems of the fuel and energy complex of the Republic of Kazakhstan: 1) lack of production capacity to meet the growing demand for energy and fuel from the economy and the population. Increased demand for electricity and heat, which will require the commissioning of new generating capacities.There is already a shortage in the fuel markets. Modernization and bringing the existing oil refineries (hereinafter referred to as refineries) to full capacity will not allow providing the domestic market until 2030; 2) the export orientation of raw materials, the dependence of the economy on the export of energy resources. In order to attract technology and investment in the oil and gas and nuclear industries, agreements on the extraction of energy resources were concluded with international export companies. In the medium term, Kazakhstan may face a shortage of oil for domestic refineries, if measures are not taken to stimulate its refining within the country. The uranium mined is fully exported; 3) high energy intensity of the economy, low level of energy efficiency. There is a high potential for increasing the efficiency of energy use both in the electric power industry and fuel production, and at the level of final consumption – in industry and housing and communal services; 4) decrease in the replenishment and quality of the resource base in the oil and gas, coal and nuclear industries; 5) low environmental friendliness of technologies used in the fuel and energy complex. Purpose: The purpose of the article is to reveal the problem in the field of ensuring the fulfillment of international obligations between different countries and their own energy sufficiency by gradually changing the structure of energy production. Methods: Studying the experience of increasing the efficiency of the use of energy resources and energy saving as a priority of the state policy of the country. Analysis of production capacity with a constantly forecasted shortage of primary energy resources and insufficient growth of capacity for the production of electricity and heat. Consideration of the possibility of compensating for the shortage by saving energy resources, increasing tariffs for energy carriers, as a stimulating factor for their effective use. Results and their significance: The results of this article will reflect the problems of energy, as the most important driving force of global economic progress. The well-being of the people depends on the state of the country's energy sector, therefore there is an urgent need to solve the emerging problems. The global energy problem is, first of all, the issue of stable and efficient supply of fuel and energy to mankind. Today, the energy sector of Kazakhstan is focused on fuel resources, since the country is provided with hydrocarbons and other energy resources. About 72 % of electricity in Kazakhstan is generated from coal, 12,3 % from hydro resources, 10,6 % from gas and 4,9 % from oil. Thus, the four main types of power plants generate 99,8 % of electricity, while alternative sources account for less than 0,2 %.
