Geopolitical transformations and their impact on the energy system are closely related to the formation of the modern world order, and the energy factor plays an increasingly important role in international relations. Currently, energy security is regulated not only by the laws of a market economy, but also by geopolitical interests. Recently, it has been observed that subjects of international relations are trying to use the energy and raw materials factor to advance their interests. In the modern world order, fierce competition and the struggle for energy resources have taken a new turn. Leading countries are striving to establish themselves firmly in regions with large reserves of raw materials. Relations in the field of production, transportation and supply of energy to foreign markets are directly related to geopolitical processes. Therefore, under the influence of geopolitical transformations, this form of relationship changes systematically and functionally. The modern international energy system is affected by the forces and factors inherent in the world order, and is becoming increasingly complex. Geopolitical transformations have a significant impact on the international energy regime, creating a new configuration of geopolitical forces. New large consumer centers are emerging in the international arena, and competition between them is growing. The emergence of new centers of power has a significant impact on international energy relations. Energy conflicts between power centers and other actors weaken the foundations of global energy security. At the same time, the lack of effective international legal mechanisms to ensure energy security complicates the energy situation. This article discusses the impact of geopolitical transformations in East Asia on energy security, geopolitical processes in the region, the impact of the geostrategic, geo-economic interests of leading countries on international and regional energy relations, the impact of economic competition and political tension on markets, investment and energy resources of the countries of the region on the total security of the region, the geopolitical situation in the region and the participation of leading states, as well as international and regional political and economic structures. Also highlights problems of energy security in East Asia, the energy situation in the region, current issues of energy in the region, energy policy and cooperation of the countries of the region, the main directions of modern architecture of energy security in East Asia, energy strategies of the countries of the region, the institutional foundations of energy security, the problems facing energy diplomacy of the states of the region, the impact of regional conflicts on energy security and other relevant issues facing today's energy security in the region. It also provides analytical forecasts of the future energy situation in the region and in the international arena. The article concludes with scientific recommendations aimed at ensuring energy security and enhancing the effectiveness of cooperation in the context of geopolitical transformation.

The article discusses the prospects for the development of the heat and power industry in the Republic of Uzbekistan. It was noted that according to the development concept of the Republic of Uzbekistan until 2035, the expected growth in electricity consumption in the Republic will be approximately from 2000 to 3156 kWh/person. This growth in electricity production is planned to be achieved by increasing the production of renewable energy sources (RES) in the structure of generating capacities from 12.7% to 19.7% by 2025, upgrading existing plants, building new combined-cycle gas plants (CCGPs) and further construction of a nuclear power plant (NPP).
Given that in the coming years to 85% of the thermal and electric energy in the Republic is generated in thermal power stations that use natural energy resources such natural gas, coal and fuel oil, and also given the greater depreciation of equipment stations and as a consequence their low efficiency, the authors emphasize the importance of using to generate these types of energy modern combined cycle technology.
It is indicated that currently there is a wide technical and industrial cooperation of the main foreign gas turbine manufacturers in the world. In the world, the main manufacturers of such equipment are three companies - General Electric (USA), Siemens - Westinghouse (Germany - USA) and Alstom (France, Switzerland, Sweden).
Variants of combined steam and gas turbine units (GTU) have been developed. As a result of the GTU operation, the gases used in the installation were proposed to be used in the steam power cycle.
Advantages of CCGP: combined-cycle plants can achieve an electric efficiency of more than 60 %. For comparison, the efficiency of steam power plants operating separately is usually in the range of 33-4 %, for gas turbine plants - in the range of 28-42 %; low cost per unit of installed capacity; combined-cycle plants consume significantly less water per unit of electricity generated compared to steam power plants; short construction time (9-12 months); there is no need for constant fuel supply by railway or sea transport; compact dimensions allow you to build directly at the consumer (factory or inside the city), which reduces the cost of power lines and transportation of electric energy; more environmentally friendly compared to steam power plants.
The disadvantages of CCGP include: the need to filter the air used for fuel combustion; restrictions on the types of fuel used. As a rule, natural gas is used as the main fuel, and diesel fuel is used as a backup fuel. The use of coal as fuel is only possible in installations with in-cycle coal gasification, which greatly increases the cost of building such power plants. This implies the need to build expensive fuel transportation communications - pipelines; seasonal capacity restrictions. maximum performance in winter.
However, despite the listed disadvantages of CCGP, at this stage of development of the Republic, combined-cycle plants can produce electricity with a high efficiency, thereby significantly saving natural gas. Approximate calculations show that the technical re-equipment of the domestic heat power industry using gas-turbine and combined-cycle technologies and environmental protection equipment developed in the world will allow saving natural gas annually in the amount of approximately 1010 m3, which in monetary terms will amount to 3 trillion soums. In General, it is concluded that
1.to solve the country's energy problems, it is necessary to accelerate the introduction of REI, technically re-equip the domestic heat and power industry using gas turbine and combined-cycle technologies developed in the world.
2.in power plants where the fuel balance contains a large proportion of fuel oil or coal, but there is also natural gas, in an amount sufficient to power the gas turbine, it may be advisable to thermodynamically more efficient gas turbine superstructures.
3.to implement the tasks of modernization and reconstruction, involve the private sector in the energy sector on the basis of public-private partnership. Create the necessary regulatory framework and technical infrastructure.

Питание является одной из важнейших составляющих здорового образа жизни человека, обеспечивает организм необходимой энергией. Рациональное питание студентов следует рассматривать как одну из главных составных частей профилактической медицины, как один из факторов здорового образа жизни молодежи. Возраст первокурсников относится к критическому периоду в жизни, что обусловлено наибольшей интенсивностью роста и развития, гормональной перестройкой организма, когда максимальны потребности в энергетических затратах. Организм человека подчиняется законам термодинамики. В соответствии, с чем различают один из принципов рационального питания: его энергетическая ценность должна соответствовать энергетическим затратам организма. К сожалению, на практике этот принцип часто нарушается. В связи с избыточным потреблением энергоемких продуктов (хлеб, картофель, животные жиры, сахар и др.) энергетическая ценность суточных рационов часто превышает энергетические затраты.
This article discusses the latest trends in energy relations in the Middle East, the impact of international and regional events on it, and current issues of energy security in the region. It also analyzes the strategies of the leading countries of the world in the field of energy supply, geopolitical and geoeconomic changes associated with the formation of new energy relations in the Middle East. Energy diplomacy and the foreign policy of the leading oil-producing countries of the Middle East at the world and regional levels are comparatively studied. The most important area in the Middle East today is undoubtedly the issue of energy. This is inextricably linked with the development needs of the countries of the Middle East, and the fuel and energy potential plays an important role in ensuring the prosperity, security and stability of the countries of the region. The Middle East, with its vast reserves, remains a hotbed of conflict in the 21st century. The geopolitical interests of leading countries such as the United States, China, the European Union and Russia clash in the region. In the context of globalization, the energy security of countries becomes the most important task of the global political process. Due to the reduction of hydrocarbon reserves, the intensification of political and economic crises in oil-producing countries, the sharp increase in consumption of raw materials, the problem of energy security is becoming an increasingly important task for international relations. Today, five of the ten leading oil producing countries in the world are located in the Middle East, including Saudi Arabia, Iran, Iraq, Kuwait and the UAE. This group of countries accounts for more than a quarter of world oil production. Energy production in the region affects not only participants in the Middle East, but also non-regional actors, the entire international energy security system. The final part of the article presents scientific recommendations for ensuring energy security in the Middle East, the formation of modern mechanisms of energy relations and constructive dialogue between the countries of the region at the international and regional levels.
The modern energy system is largely based on the use of fossil fuels, which makes up almost 90% of the global energy consumption structure. Intensive production of raw materials has a negative impact on the environment. This in turn creates environmental problems. The depletion of available reserves of the main energy resources of oil, gas, coal, ore and other minerals will worsen the energy situation in the world. Today, renewable energy interest to many countries due to increased dependence on imported energy, climate change and environmental protection, high rates of economic development and population growth. The widespread use of renewable energy sources will create socially and environmentally clean energy structures.
