Opis:
Research background: Energy policy is closely linked to economic development. Therefore, its optimization is an important issue especially in the contemporary European environmental conditions.  EU regulations enforce a reduction of carbon dioxide emissions and the abandonment of non-renewable energy resources. Instead, they promote renewable energy sources. In this way, new legal and environmental circumstances are becoming the main reason for the transformation of energy balances, which is a real economic and technological challenge. This transformation requires a strategic and effective approach, especially in those countries which until now have used mainly hard coal in the energy sector. Purpose of the article: According to above justification, the main purpose of the article is to identify the strategies for the transformation of energy balances that were implemented in the years 1990-2017 by chosen European countries and Turkey. Methods: The study period covers the years 1990-2017, and the subject of the research at first applies to all European countries, and then to 7 countries selected due to their high share of bituminous coal in energy balance in the first year of the analysis, treated as the initial point of transformation (1990). As a result of this selection, 6 EU members and Turkey with the largest share of coal in energy production in the year 1990 are examined. Particularly, an analysis of the trends in their energy balances in the years 1990-2017 is conducted. The research uses data on non-renewable energy consumption and renewable energy resources and the total energy consumption. The research methodology includes: analysis of the structure and dynamics, evaluation of trends and comparative analysis and presentation of development strategies. At the end of the article, a comparative analysis is carried out, the economic consequences of identified changes are assessed, and recommendations are formulated aimed at optimizing the structure of the energy balance in the future. Findings & Value added: Generally, there are four theoretical and empirical patterns of transformation strategies of energy balances with dominant coal consumption: 1) using other non-renewable energy resources; 2) replacing non-renewable energy resources with renewable ones; 3) using nuclear energy instead of coal; 4) increasing coal consumption as available and efficient energy resource. It was found that the examined countries implement mainly the strategy in which the decreasing share of coal is made up for by an increasing share of gas. Additionally, we can observe an increase in the share of nuclear energy in France, the Czech Republic and the United Kingdom. In Spain and Germany, despite the use of nuclear power plants for the production of energy, the share of nuclear energy in the energy balances has systematically decreased in time. In all analyzed countries, we can also observe an increasing share of renewable sources in energy balances, however, this growth is very slow.

Opis:
Research background: In recent years, much attention in the literature has been paid to the economic and environmental conditions of energy development as a key sector for the development of national economies. The issue of availability of individual energy resources and related energy security is receding into the background, most often due to the strong globalization of economies and the associated assumption of free international flow of goods and services, and thus practically unlimited possibilities of buying on the international commodity markets and energy exchanges. Nevertheless, the importance of energy security increases significantly in crisis situations. Purpose of the article: Bearing in mind the circumstances indicated above, the main objective of this article is to assess the energy security of European countries carried out in the context of resource and economic conditions. Methods: The article proposes its own methodological approach to the assessment of energy security based on the analysis of the energy mixes of 32 European countries and the availability of their own internal energy sources. In the process of classifying the studied economies into homogeneous groups in terms of resource and economic determinants (GDP per capita), principal component analysis was used. Findings & value added: The theoretical and methodological added value of the article results from the development of the author's approach to the assessment of energy security using individual and aggregated energy sufficiency index. Empirical added value is related to the results of energy security assessment in European countries, which can be used in shaping energy policies. Therefore, most of the 32 European countries assessed have a low level of energy security, which is due to the dominant use of non-renewable energy resources in their energy mixes. Countries with a high level of energy security have their own non-renewable resources or use alternative energy carriers in the form of renewable sources, hydropower or nuclear energy.

Opis:
Currently, the industry of mining machines and appliances in Poland, as a result of considerable economic improvement on the market of energetic resources, gains an incredible opportunity for further development. However, its use is dependent on the intensification of activity internationalization. Polish sales market, due to hard coal mining decrease and financial problems of mining enter-prises, does not guarantee sales increase.Therefore, the basic objective of this article is to assess the currently used internationalization strategies of Polish enterprises performing in the industry of mining machines and appliances. In the article, in the theoretical part literature studies concerning enterprises internationalization are used. Next, the characteristics of the industry of mining machines and appliances in Poland are presented, ending with a SWOT analysis. In the part devoted to a strategy of internationalization, the results of a question-naire research conducted in the group of producers of mining machines and appliances in the 2012 were used. According the research results, Polish enterprises from the industry of mining machines and appliances in the internationalization of their activity use the sim-plest strategies that do not require engagement of capital on foreign markets. Some examined enterprises have been functioning on popular markets, offering the same products. Other ones conquer new markets and/or modify the products in order to adjust them to geological-mining requirements of target markets. Diversification strategy is not used because of high risk. The examined enterprises are not able to use dumping, due to global competitors and Chinese producers. It is not profitable to use direct investments either in exploration and penetration. The reason is mostly a lack of recognition of markets remote geographically and culturally, as well as low domestic production cost which cause that Polish producers choose a focus strategy instead of a diversification strategy.

Opis:
Research background: Due to increasing economic and sector risk coal mining in Europe is treated as a declining industry. In post-transition economies such approach is a threat for energy security and local and regional economic development. Nowadays, coal mining survival in Central-East Europe is additionally threatened by accumulative global risk factors, especially by price differentiation and shale gas revolution in United States of America. Revealed circumstances require deepen research and diagnosis in the area of risk and corporate management in mining enterprises in Central-East Europe. Purpose of the article: The main aim of the article is to assess industrial risk in coal mining in Central-East Europe. The research is divided into three parts. In the first one the situation of coal mining in Central-East Europe is characterized. It is the basis for selection of the countries for the detailed analysis. In the second part the industrial risk factors are assessed and described. Finally, in the third part their influence on financial results in the examined mining enterprises is evaluated. In the summary the international comparison is made and general assumptions for risk and corporate management are formulated. Methods: In the article a risk checklist is used to identify the economic and industrial risk factors. To determine their influence on financial results on the first stage of research Pear-son’s coefficients are used. Than regression functions are developed. The data are collected on the basis of public statistics and financial statements of the examined mining enterprises. Findings & Value added: On the basis of research results it may be stated that there are only a few countries in Europe in which mining enterprises still operate as separate economic units and all of them have experienced serious financial troubles in the last years. Risk intensification contributed mostly to revenues reduction and negative financial results.
