The main principles of the smart city concept rely on modern, environmentally friendly technologies. One manifestation of the smart city concept is investments in renewable energy sources (RES), which are currently a popular direction in urban transformation. It makes sense, therefore, to analyse how Polish cities are coping with this challenge and whether they are including the implementation of RES facilities in their development strategies. The aim of the article is to analyze and assess the level at which renewable energy facilities are being implemented or developed in the urban space of cities in Poland as a pillar of the implementation of the smart city concept. This goal is realized on two levels: the theoretical (analysis of strategic documents) and the practical (analysis of the capacity of RES installations, questionnaire studies). The study shows that renewable energy installations are an important part of the development strategies of Polish cities, and especially of those that aspire to be termed “smart cities”. Moreover, it is shown that the predominant RES facilities are those based on solar energy.

The paper aims at determining the role played by funds from the European Union in the development of renewable energy sources in Poland in the context of European Union cohesion policy. We have derived data from the official European Funds Portal for the size of projects and the financial support obtained from the European Union for the use of a specific renewable energy source. We have analyzed all (928) projects related to hydro- and geothermal energy, biomass (together with biogas), wind, and solar energy implemented in all 16 voivodships (administrative regions of the second order, NUTS 2). It must be mentioned that, in the programming period 2007–2013, the available European Union funds made it possible to obtain the largest support for all investments in renewable energy sources in Poland so far. The total value of the projects co-financed from these funds has amounted to 2 billion euro. Analyzing the value of investments in technologies based on varied renewable energy sources, an evident disproportion in either the size of particular installations or the costs of investments is observed. We demonstrate that large wind farms constitute more than 60% of the total value of investments in renewable sources subsided by the European Union. Small projects have also been subsided, but mainly those related to solar energy. Generally, the wind energy investments are established in northern and western parts of Poland, including Zachodniopomorskie, Pomorskie, Dolnośląskie, and Łódzkie voivodships, while the solar energy investments are found in the eastern and southern parts of Poland.

This article examines the Polish city of Toruń in terms of the compact city concept. It analyses the theoretical elements of the compact city concept using Toruń as a case study and taking into account the psychological aspects (i.e., social perception) of a compact city. The case study collected primary data during fieldwork in 2013 and 2014. The methodology consists of a literature review, satellite photo grid analysis (250 × 250 m) and social perception of the compact city (n = 128) assessed through questionnaires with representative quantitative data. The research was also supplemented with an analysis of the accessibility of the main sites in Toruń. The results are presented on a map of urban areas and graphs of social perception. The study concludes that Toruń is a compact city from the urban point of view, but it is not perceived as such from the psychological or social points of view

Nowadays, the pace of social and economic development is constantly growing, which has led to many negative effects. In order to stop this negative impact, reference should be made to the assumptions of sustainable development (SD), and young people – Generation Z – should be considered its main promoters. The main objective of this article is to present Generation Z’s perception of sustainable development in Poland. A Computer-assisted web interviewing survey (CAWI, N=1172) was conducted to understand the basic demographics, general issues, SD in a daily context, and SD-related knowledge in 936 cities of Poland. The results have shown that Generation Z in Poland recognises the social and inclusive role of SD. Cost of commodities, social disparities and conflict, and disrupted economic growth were identified as the emerging challenges for Sustainable Development Goals (SDGs) in Polish cities.
