Дана стаття присвячена аналізу доцільності використання методу головних компонент для формування математичної моделі електроспоживання карусельної сушарки з метою оцінювання рівня енергоефективності. В результаті застосування методу головних компонент визначено чинники, які мають найбільший вплив на споживання електроенергії. Точність сформованих регресійних моделей електроспоживання оцінювалась на основі визначення середньої відносної похибки, середньоквадратичної похибки та коефіцієнта варіації. Ключові слова: метод головних компонент; регресійний аналіз; математична модель; споживання електроенергії; базовий рівень енергоефективності

The European Union is pursuing an ambitious energy policy to reduce the emission of pollutants into the environment and achieve complete decarbonization by 2050. According to the approved Green Deal, each European state had to introduce its own energy strategy based on its own economic, social, climatic, and climatic conditions. In the process of European integration, Ukraine has developed its own strategies that meet the principles of European government policy. The analysis of the experience of implementation of energy strategies of different member states of the European Union will have a positive impact on the process of implementation of the new energy policy in Ukraine. According to this, a comparative analysis of strategies and the state of the fuel and energy complex of France, Austria, Poland, which have common features with the energy system of Ukraine. As a result of the study, it was found that the process of decarbonization should be gradual. Abrupt changes can lead to negative consequences in economic and social aspects. The information obtained can be useful for energy reforms in Ukraine.

This article presents the results of the proposal describing the conducting collection, reviewing and analysis of the information on existing trainings and training institutions for building energy efficiency in Ukraine. Also this article contents preliminary results of identification of capacity needs of training institutions for building energy efficiency for potential improvement of already existing training. There consider the following issues: 1) short description of the methodical approach and proposing an outline of the study; 2) the main education and training institutes for building energy efficiency in Ukraine; 3) training and qualification measures on energy efficiency that are offered in Ukraine; 4) identification of capacity needs of training institutions for building energy efficiency for potential improvement of already existing training.
