The ongoing climate changes necessitate an effective climate policy. The energy transition is now an important topic and problem, especially in Poland. (1) The undertaken analysis of the problem of energy transition is important for political, social and technological reasons. Political, because it shows the weakness of the implementation of Polish energy policy in regards to climate change. Social, because energy transition will bring about significant social changes in the largest industrial region of Poland. Technological, as the departure from fossil fuels requires the introduction of other sources of energy on a massive scale, for which Poland is not prepared. The aim of the study was to critically analyse the activities to date in the field of energy transition in Poland. The second goal of the analysis was an attempt to answer the question of whether the process of energy transition and achieving the goals set in the EU’s European Green Deal are possible at all until 2050. (2) To achieve the goals, the system method and the decision-making method were primarily used. These methods allowed for an examination of the main determinants of the Polish energy transformation. (3) The main results include the confirmation, contrary to the announcements of the Polish government, that despite the adoption in Poland of the strategy “Poland’s energy policy until 2040”, the effective implementation of the energy transition before 2050 is not only very difficult, but may even be impossible to implement in the assumed time. This is due to political, economic, social and technological conditions. Coal energy is outdated, expensive and ineffective. Due to natural conditions, wind energy is not able to meet the energy demand of the industry. The development of nuclear energy is only in the planning phase. (4) To sum up, in the next thirty years, Poland will not be able to achieve the assumed effects of the energy transition, which is in contradiction with the official declaration of the government.

The European Union aspires to pursue an ambitious climate policy. The energy sector is a key tool to ensure success in this area. At the same time, excessively ambitious targets can be a serious problem for individual member states. The aim of the article is to analyze the possibilities...

The present article presents an analysis of the potential application of 3D printing in the critical infrastructure system. An attempt has been made to develop case studies for selected critical infrastructure areas, particularly with reference to the area of energy supply. The need for 3D printing applications is identified based on expert research in the energy industry. It identifies the application schemes determined by the technical and logistical possibilities associated with 3D printing in its broadest sense. A review of additive technologies with a view to their application in selected phases of critical infrastructure operation, including in crisis situations, is also carried out. Furthermore, a methodology for incorporating 3D printing into the existing critical infrastructure system is proposed. As a result, the following research hypothesis is adopted: the use of 3D printing can be an important part of measures to ensure the full functionality and efficiency of critical infrastructures, particularly in crisis situations.

Polityka energetyczna Unii Europejskiej w kontekście problematyki bezpieczeństwa gospodarczego

Artykuł dotyczy problematyki rozwijania elektromobilności w Polsce na tle planów związanych z kształtowaniem krajowej polityki energetycznej. Pojazdy elektryczne stanowią ważne wyzwanie dla polityki transportowej na świecie. Ich rosnąca popularność jest odpowiedzią na problemy zanieczyszczenia środowiska oraz ma związek z działaniami na rzecz zapewnienia zrównoważonego rozwoju. Polska jest państwem, które zamierza podążać w kierunku rozwijania transportu elektromobilnego. Przygotowano w tym celu odpowiednią strategię oraz ustanowiono prawo i wskazano instytucje odpowiedzialne w tym zakresie. Niestety główna idea, jaka towarzyszy elektromobilności – czyli ekologia, nie idzie w parze z planami w zakresie polskiej polityki energetycznej. Zgodnie z oficjalnymi programami rządowymi, produkcja energii w Polsce do roku 2040 ma bazować na wykorzystaniu węgla. Oznacza to, że pojazdy elektryczne będą zasilane tzw. „brudną energią”. Hipoteza artykułu brzmi: rozwój elektromobilności w Polsce, trudno uzasadnić w kategoriach pozytywnego wpływu na środowisko naturalne i ochronę klimatu w sytuacji, kiedy wytwarzanie energii opiera się na węglu. Bez zmian w polityce energetycznej, elektromobilność „po polsku” jest pomysłem nietrafionym, ponieważ nie spełnia podstawowych założeń – czyli nie przyczyni się do zmniejszenia negatywnego wpływu transportu na środowisko.
