The impact of climate change on the economy and environment humans live in has increased, leading to a relatively quick intensification of the effort to reduce the environmental foot-print of the civilisation. The push to establish a sustainable energy economy has become one of the primary challenges today. A sustainable energy economy should ensure energy security, reduce energy poverty, and contribute to lower greenhouse gas emissions. Poland is facing considerable challenges relevant to the objectives of EU policy, particularly the Fit for 55 package, which cannot be achieved without renewable energy sources. The most popular renewable energy source in Poland is solar energy. Apart from its obvious advantages, the use of distributed photovoltaic generation (including microgeneration) entails the need for transmission grid upgrades. The paper’s objective was to assess the RES potential of Poland through an analysis of the steps the state took and the progress of its targets. The empirical part focuses on the assessment of the use of the solar energy potential (in photovoltaic microgeneration) in cities with district rights in Silesian Voivodeship, Poland, from 2014 to 2020. The study employs selected cartographic representation, comparative analysis, in-depth case study, and spatial analysis methods. The calculations involved data from Tauron Dystrybucja SA on the number of microgeneration systems in the cities, Database of Topographic Objects, Local Data Bank of the Central Statistical Office of Poland and Eurostat.

Zmiany klimatu w coraz większym stopniu wpływają na gospodarkę i ludzkie zachowania. W stosunkowo krótkim okresie zmieniło się postrzeganie wpływu człowieka na klimat. Dążenie do zrównoważonej gospodarki energetycznej stało się jednym z głównych wyzwań obecnych czasów. Zrównoważona gospodarka energetyczna powinna zapewniać m. in. bezpieczeństwo energetyczne, niwelować tzw. ubóstwo energetyczne oraz przyczyniać się do zmniejszania emisji gazów cieplarnianych. Przed Polską stoją ambitne wyzwania związane z celami polityki unijnej zwłaszcza tzw. pakietu FIT 55, których nie da się osiągnąć bez wykorzystania odnawialnych źródeł energii (oze). Wykorzystanie energii słonecznej jest jednym z priorytetowych działań. Wykorzystanie fotowoltaiki „rozproszonej” (czyli m. in mikroinstalacji) oprócz oczywistych korzyści wiąże się także z koniecznością modernizacji sieci przesyłowych. Celem niniejszej pracy jest ocena wykorzystania oze, a w szczególności mikroinstalacji fotowoltaicznych, w ciągu ostatnich pięciu lat (2015-2020), w wybranych powiatach. Poddane analizie zostaną także zastosowane instrumenty ekonomiczne i prawne, przyczyniające się do inwestycji w mikroinstalacje.

Increasing environmental awareness, perceived climate change and easier access to information have contributed to changing the perception of the environment and its reserves. Unfortunately, it happens that still misunderstood economic development and urbanization contribute to inefficient management of the city’s resources, such as space. The aim of this paper is the assessment of the impact of unused urban space for widely understood city attractiveness. The research was conducted on the example of Katowice city. The article presents the results of identification of unused urban spaces, made based on information contained in the study of spatial development conditions and directions, and available orthophotomaps and topographic maps using GIS type software. The theoretical aspects connected with the influence of unused areas on the attractiveness of the city and the results of research carried out by the Otodom service were used for the analysis.

One of most common natural catastrophes in Poland are undoubtedly floods. Climatic change contributes to more and more often and violent occurrences of the maximum flow in rivers, which increases flood damage. Inadequate land management and the unjustified belief in the effectiveness of technical flood control measures can also contribute to flood damage. The development of water management (including flood protection) should be carried out in a sustainable way by integrating social, environmental, and economic objectives. In flood protection, those measures that are least invasive to the natural environment should be used first; in particular, non-technical flood protection methods (e.g., flood risk assessment and management, and the proper definition and management of flood plains). One of the bases for the sustainable development of water management is the preparation of models that can help us calculate the likelihood of maximum flow and to identify areas that are at risk of flooding. On this basis, the proper spatial policy and prevention of flood effects will be possible. This article presents the probabilistic analysis carried out on the flood risk dynamics for a selected area of the Odra River basin. The authors based their risk dynamic assessment on the results from the distributions of the maximum values for a selected hydrological characteristic – the flow rate. Based on the daily flow data from the years of 1994–2013 collected at a hydrological station on the Odra River in Malczyce, the 30-day flow maxima were set individually for four 5-year periods. Then, a probabilistic model of the maximum flow was developed based on these peaks for each 5-year period. The resulting models were used to estimate flood risks and for analyzing the dynamics for the studied area.
