This paper focuses on the issue of energy efficiency management in the region of Prešov self-governing region (PSR), Slovakia, as the energy market is liberalized and the behavior of electricity consumers is influenced not only by conventional but also by alternative suppliers of this type of energy. Based on the statistical evaluation of a questionnaire survey focused on the emotional, behavioral, and cognitive behavior of consumers, a model of optimization of system processes of energy efficiency management at the regional level is presented. A one-way ANOVA and t-test were used to determine statistically significant differences, and Pearson’s correlation coefficient was used to determine a statistically significant relationship. Based on the obtained results, a suitable candidate for efficient electricity management is an employee aged 36 to 50 with a technical focus. The proposed model of optimizing the processes of energy management efficiency at the regional level can also be applied to the supraregional level in the understanding of the geographical division of the European Union, where the same legislative regulations are applied within the liberalized electricity market.

Energy Reform

The Ukrainian energy system is one of the least efficient in the world. In terms of energy intensity, GDP is one of the last places in the corresponding world rankings. The need to reduce energy consumption of production is a key driver of reforming the energy sector of Ukraine's economy. Ukraine's international commitments and strategic course for integration with the European Union set priorities in the country's energy policy. Ukraine's energy strategy reflects key areas for the future development of the industry and is developed in the light of global trends and experience of the European Union. However, the implementation of the strategy requires a number of measures, including the adaptation of national legislation to the requirements of the European Union in order to form a new model of a competitive energy market. In addition, an important aspect of energy reform is the innovative nature of the measures envisaged for implementation. In particular, particular attention should be paid to the application of technologies that will form the basis of the energy system in the medium to long term. Such technologies include, in particular, “smart” grids that require a systematic approach to scale them up. The article deals with the reasons of low energy efficiency of the Ukrainian economy and the dynamics of the energy intensity index of the gross domestic product of Ukraine from the early 90s to the present and its relation with the world average. The structure of the country's energy balance and transformation of the electricity market are considered as one of the key directions of reforming the country's energy system. In addition, the article identifies that the development of "smart" energy networks is today an alternative direction for the development of electricity. The importance of continuous support of energy market participants for the formation of favorable business and investment environment is identified, as well as the potential consequences of state policy fluctuations of energy market actors on the example of solar energy support in Ukraine are identified. Keywords: "smart" grids, energy, GDP, energy strategy.

The process of energy saving and its components in the production sphere is investigated. It is determined, that the national policy of energy saving deals with the increase of fuel-energy recourses extraction, application of non-conventional renewal energy sources, maximum usage of energy saving potential, as well as adapting of the national law system to the EU standards. The need to make alterations in the Energy Strategy of Ukraine till 2030 concerning the increase of importance of energy saving control processes and energy efficiency of different types of recourses during the period of the Fourth energy-package implementation in the European Union is substantiated. It is shown, that successful control of the energy saving processes in the production sphere can be obtained by energy efficiency resulting in the decrease of electric energy consumption per product during production, the cost of the renewal energy sources and noxious substances wastes. It is noted, that according to the law of Ukraine «On energy efficiency» it is expected, that energy efficiency specifies the equipment, technologies, production or system on the whole and it indicates the level of energy resources consumption per product production. The increase of energy efficiency is obtained by the introduction of some organizational and engineering measures in the production process. Energy efficiency and energy saving are interrelated processes, which testify the level of efficiency the fuel-energy resources consumption per final production unit. Energy efficiency describes the quality processes in energy sources application, having both political and social problems, and require the implementation of new society approaches to the application of energy recourses. It is noted that the Energy Union envisages the creation of a single architecture of the electricity market, which should promote the market integration of electricity generated by renewable energy sources (RER) and increase the energy efficiency of the European economy.

The article analyses critera applying to the choice of energy efficient high quality light sources and luminaires, which are used in Russian domestic and international practice. It is found that national standards GOST P 54993–2012 and GOST P 54992– 2012 contain outdated criteria for determining indices and classes of energy efficiency of light sources and luminaires. They are taken from the 1998 EU Directive #98/11/EU “Electric lamps”, in which LED light sources and discharge lamps of high intensity were not included. A new Regulation of the European Union #874/2012/EU on energy labelling of electric lamps and luminaires, in which these light sources are taken into consideration, contains a new technique of determining classes of energy efficiency and new, higher classes are added. The article has carried out a comparison of calculations of the energy efficiency classes in accordance with GOST P 54993 and with Regulation #874/2012/EU, and it is found out that a calculation using GOST P 54993 gives underrated energy efficiency classes. This can lead to interdiction of export for certain light sources and luminaires, can discredit Russian domestic manufacturer light sources and does not correspond to the rules of the World Trade Organization (WTO).

Optimal Bidding

In the recent electricity market framework, the profit of the generation companies depends on the decision of the operator on the schedule of its units, the energy price, and the optimal bidding strategies. Due to the expanded integration of uncertain renewable generators which is highly intermittent such as wind plants, the coordination with other facilities to mitigate the risks of imbalances is mandatory. Accordingly, coordination of wind generators with the evolutionary Electric Vehicles (EVs) is expected to boost the performance of the grid. In this paper, we propose a robust optimization approach for the coordination between the wind-thermal generators and the EVs in a virtual<br>power plant (VPP) environment. The objective of maximizing the profit of the VPP Operator (VPPO) is studied. The optimal bidding strategy of the VPPO in the day-ahead market under uncertainties of wind power, energy<br>prices, imbalance prices, and demand is obtained for the worst case scenario. A case study is conducted to assess the e?effectiveness of the proposed model in terms of the VPPO's profit. A comparison between the proposed model and the scenario-based optimization was introduced. Our results confirmed that, although the conservative behavior of the worst-case robust optimization model, it helps the decision maker from the fluctuations of the uncertain parameters involved in the production and bidding processes. In addition, robust optimization is a more tractable problem and does not suffer from<br>the high computation burden associated with scenario-based stochastic programming. This makes it more practical for real-life scenarios.<br>

The regulation of vehicular CO2 emissions determines the permissible emissions of vehicles in units of g CO2/km. However, these values only partially provide adequate information because they characterize only the vehicle but not the emission of the associated energy supply technology system. The energy needed for the motion of vehicles is generated in several ways by the energy industry, depending on how the vehicles are driven. These methods of energy generation consist of different series of energy source conversions, where the last technological step is the vehicle itself, and the result is the motion. In addition, sustainability characterization of vehicles cannot be determined by the vehicle’s CO2 emissions alone because it is a more complex notion. The new approach investigates the entire energy technology system associated with the generation of motion, which of course includes the vehicle. The total CO2 emissions and the resulting energy efficiency have been determined. For this, it was necessary to systematize (collect) the energy supply technology lines of the vehicles. The emission results are not given in g CO2/km but in g CO2/J, which is defined in the paper. This new method is complementary to the European Union regulative one, but it allows more complex evaluations of sustainability. The calculations were performed based on Hungarian data. Finally, using the resulting energy efficiency values, the emission results were evaluated by constructing a sustainability matrix similar to the risk matrix. If only the vehicle is investigated, low CO2 emissions can be achieved with vehicles using internal combustion engines. However, taking into consideration present technologies, in terms of sustainability, the spread of electric-only vehicles using renewable energies can result in improvement in the future. This proposal was supported by the combined analysis of the energy-specific CO2 emissions and the energy efficiency of vehicles with different power-driven systems.

The main goal of setting energy efficiency priorities is to find ways to reduce energy consumption without harming consumers and the environment. The renovation of buildings can be considered one of the main aspects of energy efficiency in the European Union (EU). In the EU, only 5% of the renovation projects have been able to yield energy-saving at the deep renovation level. No other study has thus far ranked the EU member states according to achieved results in terms of increased usage in renewable sources, a decrease in energy usage and import, and reduction in harmful gas emissions due to energy usage. The main purpose of this article is to perform a comparative analysis of EU economies according to selected indicators related to the usage of renewable resources, energy efficiency, and emissions of harmful gasses as a result of energy usage. The methodological contribution of our study is related to developing a complex and robust research method for investment efficiency assessment allowing the study of three groups of indicators related to the usage of renewable energy sources, energy efficiency, and ecological aspects of energy. It was based on the PROMETHEE II method and allows testing it in other time periods, as well as modifying it for research purposes. The EU member states were categorized by such criteria as energy from renewables and biofuels, final energy consumption from renewables and biofuels, gross electricity generation from renewables and biofuels and import dependency, and usage of renewables and biofuels for heating and cooling. The results of energy per unit of Gross Domestic Product (GDP), Greenhouse gasses (GHG) emissions per million inhabitants (ECO2), energy per capita, the share of CO2 emissions from public electricity, and heat production from total CO2 emissions revealed that Latvia, Sweden, Portugal, Croatia, Austria, Lithuania, Romania, Denmark, and Finland are the nine most advanced countries in the area under consideration. In the group of the most advanced countries, energy consumption from renewables and biofuels is higher than the EU average.
