Improving energy efficiency and reducing greenhouse gases is a central issue of the Europe 2020 strategy. Today enormous electric energy is consumed by the street lighting. Much of it could be saved through suitable energy-conservation measures (ECMs). The energy audit of the street lighting system in the Pravets municipality was carried out in compliance with the legislation in force in the EU and Bulgaria. Data about the present state of street lighting and electricity consumption for a period of 3 years were gathered and analysed. The baseline electricity consumption was defined. Classification of streets was done and the light class of the different categories streets was determined. The potential for energy savings was identified and a package of ECMs was developed. The annual electricity savings are 680 MWh (or 57,441 €/y) and the annual CO2 emissions savings are 557,640 t. The investment for implementation of the envisaged ECMs is 414,840 €. The expected electricity savings compared to the baseline are 75%.

Abstract Subject and purpose of work: A quantitative measurement of the implementation of the objectives of the Europe 2020 strategy, an assessment of the degree of implementation of the strategy objectives for the individual EU-27 countries, and a ranking of countries in terms of the implementation of the strategy objectives were carried out. Materials and methods: The empirical analysis used EUROSTAT statistics covering the values of the basic indicators of the Europe 2020 strategy in the five main areas of development. The TOPSIS linear ordering method was used. For each country, a synthetic measure was established to express the level of achievement of the objectives of the strategy. On the basis of the value of the synthetic measure, a ranking of the countries was created in terms of the degree of the implementation of the Europe 2020 strategy objectives. A ECONOMIC AND REGIONAL STUDIES STUDIA EKONOMICZNE I REGIONALNE ISSN 2083-3725 Volume 14, No. 2, 2021 ECREG STUDIES Results: Vol. 14, No. 2, 2021 www.ers.edu.pl PDF OPEN ACCESS eISSN 2451-182X quantitative approach was adopted in order to compare the effects of implementing the strategy assumptions. Groups of countries with a similar level of strategy implementation were identified. Conclusions: The research confirmed the existence of a significant diversification of the results of implementing the strategy objectives in the EU-27 countries. The differences were particularly visible between the highly developed Western European countries and the South European countries, severely weakened by the economic crisis of 2008–2009 and the recession of 2012–2013. The values of the synthetic measure allowed to determine the degree of the implementation of the objectives of the strategy and to create a ranking of the EU-27 countries. The adopted approach made it possible to compare the obtained classification of the Member States into groups with a similar level of achievement of the objectives of the strategy and to define measurable effects of the implementation of the “Europe 2020” strategic plan.

Europe 2020 Strategy highlights bioeconomy as a key element for smart and green growth in Europe. Bioeconomy in this case includes agriculture, forestry, fisheries, food and pulp and paper production, parts of chemical, biotechnological and energy industries and plays an important role in the EU’s economy. The growth of key industries of bioeconomy – agriculture and forestry – highly depends on an efficient and productive use of land as a production resource. The overall aim of this paper is to evaluate opportunities for development of the main sectors of bioeconomy (agriculture and forestry) in the EU based on the available resources of land. To achieve this aim, several methods were used – monographic, analysis and synthesis, induction and deduction, statistical analysis methods. The findings show that it is possible to improve the use of land in the EU Member States. If all the Member States reached the average EU level, agricultural products worth EUR 77 bln would be annually additionally produced, which is 19 % more than in 2014, and an extra 5 billion m3 volume of forest growing stock would be gained, which is 20 % more than in 2010.

Didik Ariwibowo, in this paper explain that energy audit activities conducted through several phases, namely: the initial audit, detailed audit, analysis of energy savings opportunities, and the proposed energy savings. Total energy consumed consists of electrical energy, fuel, and materials in this case is water. Electrical energy consumption data obtained from payment of electricity accounts for a year while consumption of fuel and water obtained from the payment of material procurement. From the calculation data, IKE hotels accounted for 420.867 kWh/m2.tahun, while the IKE standards for the hotel is 300 kWh/m2.tahun. Thus, IKE hotel included categorized wasteful in energy usage. The largest energy consumption on electric energy consumption. Largest electric energy consumption is on the air conditioning (AC-air conditioning) that is equal to 71.3%, and lighting and electrical equipment at 27.28%, and hot water supply system by 4.44%. Electrical energy consumption in AC looks very big. Ministry of Energy and Mineral Resources of the statutes, the profile of energy use by air conditioning at the hotel by 48.5%. With these considerations in the AC target for audit detail as the next phase of activity. The results of a detailed audit analysis to find an air conditioning system energy savings opportunities in pumping systems. Recommendations on these savings is the integration of automation on the pumping system and fan coil units (FCU). The principle of energy conservation in the pumping system is by installing variable speed drives (VSD) pump drive motor to adjust speed according to load on the FCU. Load variations FCU provide input on the VSD pumps to match. Adaptation is predicted pump can save electricity consumption up to 65.7%. Keywords: energy audit, IKE, AC

Research background: Economic crisis hit all the European Union Member States hard, with the impact of crisis varying considerably. The low growth performance in the EU has increased concerns regarding an increasing wage dispersion, income inequality at large, and social exclusion in line with poverty. Inequality should be seen as a cornerstone of both sustainable and inclusive growth under the Europe 2020 Strategy. Social inequality in the EU is a real problem, which hampers sustainable economic growth. Purpose of the article: The purpose of this study is to introduce evaluation of social development convergence and divergence trends between the EU Member States in the context of the Europe 2020 Strategy. The study gives an outline of the issues of the labour market and income disparities and poverty. Policymakers must be clear about what social objectives they are aiming to achieve, therefore special attention is paid to headline national goals of the Europe 2020 Strategy. Methods: The main task of this study is to assess social dimension and inequalities problems in the EU27 by applying Data Envelopment Analysis method, resp. time-series dynamic efficiency analysis in the form of output-oriented Malmquist Productivity Index. This study contains changes of key social equality indicators related to the Europe 2020 Strategy and compares objectives and general outlines of period 2010-2015, as well as the impact on national economics and living conditions. Findings & value added: Results contain elements of typology premises of the EU28 and point to a large diversity in inequality patterns, as the Author observes both increases and decreases in inequality at the EU level. Recent changes in social inequality have been associated with the business cycle, particularly with the accessibility of the labour market and, of course, with income inequality. Additionally, the development challenges are discussed for improvement of the socioeconomic well-being of the EU and to avoid social disparities.

The aim of this study was to examine the electric energy consumption of milking process on dairy farms and to evaluate the methods to improve the energy efficiency. The electricity consumption of the milking process was measured on three dairy farms in Southern Finland, and it varied between 37–62 Wh kg-1 milk.  The largest energy saving potential was identified in milk cooling and the heating of cleaning water. Even simple methods, such as placing the condenser of the refrigeration system outside, may reduce the energy consumption of milk cooling by 30%. Efficient milk pre-cooling can reduce the energy consumption of the whole milking process by more than 25%. Even larger energy savings are possible with a sophisticated milk cooling – water heating systems. It was concluded that there is a significant potential to reduce the energy consumption and energy costs of the milking process, and thus to improve the profitability and sustainability of the sector at the same time.

I define first of all the competitiveness in my study „Analysing the competitiveness of the European Union”. After that I turn to the analysis of the competitiveness of the EU. The European competitiveness index and its concept were of great assistance during the analyses. The concept of the European competitiveness index has three main components: creative economy, economic performance, access to infrastructure. It is unambiguous that the European Union can only sustain and increase its position reached in the world economy, when its member states commit themselves for the completion of the knowledge based economic policy striving for competitiveness. The Europe 2020 strategy and the budget period 2007–2013 emphasize the outstanding role of competitiveness and urge to take the necessary measures.

Measuring and monitoring the implementation of the concept of sustainable development is an important aspect of the assessment of the functioning of EU countries. One of the pivots of sustainable development is social order, although the literature analysis indicated that multidimensional empirical research in this area is scarce. The main goal of this article was to present the diversity of indicators characterizing social development in EU Member States in the context of progress made by each of them in implementing the concept of sustainable development between 2014 and 2018. The purpose of this article was also to compare Poland with the other EU countries in the years 2014 and 2018. The research procedure consisted of two stages. The first stage was to analyse and assess the regional differentiation of the values of variables explaining social development in the EU in the context of implementing the concept of sustainable development. The second stage envisaged a multidimensional assessment of the diversity of the thematic areas identified in the first stage, as well as a characterization of social development in the EU in the context of implementing the concept of sustainable development. Based on the obtained results, a conclusion could be drawn that many countries are witnessing positive trends which bring them closer to the successful implementation of the sustainable development paradigm—one of the principal priorities of the Europe 2020 strategy, a long-term socio-economic program of the EU. The multidimensional analysis also showed that the level of social development in the context of sustainable development differs across the EU. Particularly notable differences among EU countries could be observed for the variables denoting labour market and health, with demography being the least diversified of all areas. In Poland, the indicators regarding poverty and social exclusion improved significantly as a result of the implementation of numerous social programs. In addition to that, a positive change in education indicators was also reported in Poland. This favourable trend indicates that some of the goals set out in the Europe 2020 strategy have already been met by Poland while others are becoming increasingly attainable.
