The economic dimension of the electromagnetic process : comparison study of costs of repairs of electric vehicles and powered with conventional fuels

The development of electro-mobility in Poland is one of the inevitable processes awaiting the Polish automotive industry. For each potential electric vehicle user, the information on the vehicle’s operating costs therefore becomes an imperative of tremendous importance. The analysis of market prices of passenger cars clearly indicates that the costs of acquiring a new electric vehicle are much higher than conventional fuel vehicles. Therefore, the expectations of customers themselves become fundamentally significant, who in relation to the spare parts in the case of this category of vehicles expect the highest technological and quality standards while maintaining the suitable price parameter. The article attempts to signal the issues related to the evaluation of electro-mobility parameters by presenting the comparative study of the costs of repairing electric vehicles and vehicles fuelled by conventional fuels. Considerations were supplemented by authoritative cost simulations, including the comparison of the same models of vehicles equipped with both the conventional and ecological power units. The aim of the article is to draw attention to the essence of the research problem and to answer the question whether the total costs of operating electric vehicles are in reality significantly lower than that of vehicles fuelled by conventional fuel.

The article aims to assess the economic recovery and recycling of silicon PV cells and the non-ferrous metals contained in them, taking into account the analysis of costs, benefits and factors: legal, ecological, technical, technological and social. The research methodology was based on statistical measures related to the analysis of PV structure and changes in individual years of operation. For the designated structures, the current state of knowledge and legal status in the field of recycling methods of exploited PV installations were defined. In addition, an analysis of the Polish market about selected developed countries concerning the recycling sector was performed, and the identification of key factors and barriers to the development of the analysed sector was presented. On this basis, the possibilities and directions of support for the PV recycling sector were indicated, and a SWOT analysis of possible methods of its support was made.

Celem artykułu jest ocena ekonomiczna odzysku i recyklingu krzemowych ogniw PV i zawartych w nich metali nieżelaznych z uwzględnieniem analizy kosztów, korzyści i czynników: prawnych, ekologicznych, techniczno-technologicznych i społecznych. Metodologię badań oparto na miarach statystycznych związanych z analizą struktury i zmian PV w poszczególnych latach ich eksploatacji. Dla wyznaczonych struktur określono aktualny stan wiedzy i stan prawny w zakresie metod recyklingu wyeksploatowanych instalacji PV. Ponadto wykonano analizę rynku polskiego względem wybranych krajów rozwiniętych odnośnie sektora recyklingu, przedstawiono identyfikację kluczowych czynników i barier rozwoju analizowanego sektora. Na tej podstawie wskazano możliwości, kierunki wsparcia sektora recyklingu PV i dokonano analizy SWOT możliwych metod jego wsparcia.
