Motor fuel is an important component of both energy and national security of any country in the world, as it provides civilian transport and military equipment with the necessary energy resource. After the invasion of the armed forces of the russian federation on the territory of Ukraine and the destruction resulted from shelling of a number of oil and gas processing plants in the country, a difficult situation has developed that requires either an urgent restoration or creation of a new production of motor fuel on the country’s own raw material base. The aim of the study is to determine the current status of the raw-materials potential for the production of motor fuel in Ukraine and its regions. To achieve this goal the authors have: considered the combustible minerals of the country; analyzed the distribution of reserves and production of natural gas, oil, coal, and peat; examined the structure of distribution of their balance extractive reserves by regions of Ukraine, and the dynamics of production; computed the total energy potential of combustible minerals of Ukraine; identified sources of renewable resources that can be used for energy production; determined that the first-generation liquid biofuels include bioethanol and biodiesel; calculated the current technical potential of bioethanol production from corn and rapeseed by regions of Ukraine; identified the leading regions in terms of the potential for the production of liquid biofuels in Ukraine; formed the structure of energy potential by types of combustible minerals and biofuels in the country; determined the total energy potential of combustible minerals of Ukraine and formed the structure of the total energy potential of combustible minerals and biofuels in the regions of the country

The purpose of the article is to analyze and evaluate the structures and condition of the Armed Forces of Ukraine and the aggressor country of russia, as well as to develop a methodological approach that will allow to assess and compare the military forces of countries. The article assesses the state and structure of the Armed Forces of Ukraine and the aggressor country of russia by types and branches of the armed forces. Attention is paid to the assessment and comparison of the Armed Forces of Ukraine and russian federation by such indicators as the number of military personnel, the number and quality of tanks, armored personnel carriers, airplanes and helicopters, ships and boats of the Navy, and anti-aircraft warfare systems of the Air Force of Ukraine. The authors substantiate a methodological approach to assessing the military power of countries based on the following provisions: when assessing the military power of the world countries, it is necessary to carry out both a general assessment of the military power of the Armed Forces and the types and branches of the armed forces; when assessing the military power of the types and branches of the armed forces of the world countries, it is necessary to take into account both the number of weapons and military equipment belonging to them and the quality of their structure; assessment of the military power of the Armed Forces should be carried out for countries between which a military conflict or a full-scale war is possible; assessment of the military power of the Armed Forces of the world countries should take into account the possibility of their participation in a particular generation of war. A formula for an integrated assessment of the military power of the Armed Forces of a country is proposed. On the basis of the developed methodological approach and the proposed formula, the military power of Ukraine and russian federation is estimated and compared.

The article is aimed at substantiating the basic technical-economic characteristics of energy plantations of miscanthus and production of solid fuels from the obtained biomass on the example of a particular project. As a result of the study: the analysis of the production volume of solid biofuels on the basis of quantities from a given area of plantation was carried out; net income of the complex was determined, which was calculated on the basis of accepted production volumes and «reasonable» wholesale prices, which were determined in a costly manner and provided for the provision of a sufficient level of profitability of economic activity; the current (operational) costs of economic activity of the complex were determined, calculated according to the standards established by analogues of industrial production of biomass from energy crops and its processing into solid biofuels. Also the economic feasibility of implementing an investment project on laying the plantation of miscanthus and production of solid biofuels from the resulting biomass was assessed. In general, in the presence of adequate State-based stimulation of solid biofuel production from miscanthus biomass, the economic efficiency of the project will be high, and the project itself is commercially feasible. Prospects for further research in this direction are substantiation of the main technical-economic characteristics together with feasibility of creating complexes for the transformation of solid biofuels into commodity energy – both electric and thermal.
