Připravenost obcí mikroregionu Moštěnka k posílení energetické soběstačnosti
Hrudíková, Jana
This bachelor thesis deals with the analysis of the preparedness of the municipalities of the Moštěnka micro-region to strengthen energy self-sufficiency. The main objective of this thesis is to find out to what extent the municipalities are currently equipped and what are the prerequisites for the transition to energy self-sufficiency. The theoretical part defines energy self-sufficiency and the conditions that it is necessary to meet for its realization. These are energy-efficient houses and use of renewables. Subsequently, research on the functioning of the energy sector in the Czech Republic is conducted. The analytical part consists of three main chapters, namely the natural conditions that are central to the use of renewable energy sources, the current state of buildings and energy infrastructure. Subsequently, a set of recommendations is included that municipalities can follow in the future to increase energy self-sufficiency.
The Iberian Peninsula's role on the European energy networks as a gateway to the global market
Mineiro Gonçalves, João Pedro ; Doboš, Bohumil (advisor) ; Romancov, Michael (referee)
Bibliographic note GONÇALVES, João P. M. (2023). The Iberian Peninsula's Role in the European Energy Networks as a Gateway to the Global Market. 98 p. Master thesis. Charles University, Faculty of Social Sciences, Institute of Political Studies, Supervisor Mgr. Bohumil Doboš, Ph.D. Abstract This thesis examines the role that the Iberian Peninsula might play within the European Union's efforts for energy integration, while also analysing the potential of this region to produce and export energy from renewable sources and renewable gases through the development of renewable industrial capacities. The research looked at official documents and legislation from the EU, as well as reports from expert groups and international institutions to collect and analyse data regarding energy consumption, production capacity and interconnectivity in Iberia and its neighbouring region. The research showed promising data for a largely untapped renewable potential across Portugal and Spain, accompanied by optimal conditions for a large-scale production of green hydrogen, which allowed us to conclude that the Iberian Peninsula can become one of the main hydrogen corridors in the world in the near future, contributing to the clean energy transition in Europe and the European neighborhood.

The bachelor's thesis is focused on the topic of renewable resources. The first part of the thesis deals with the description of individual renewable sources such as solar energy, wind energy, water energy and energy from biomass. The second content of the bachelor's thesis is the approximation of trends in renewable resources and modern energy. The content includes individual possibilities for non-traditional use of renewable resources that can be applied in the future energy sector. The third chapter deals with the possibilities and limitations of renewable resources in the Czech Republic.
Recycling modern cars
Borik, Matúš ; Charvát, Pavel (referee) ; Štětina, Josef (advisor)
Zem čelí nadmernému prekračovaniu recyklačných limitov organických a anorganických surovín, čo spôsobuje nedostatočnú absorpciu skleníkových plynov. Automobilový priemysel sa v posledných desaťročiach rapídne rozbehol a má na tom svoj podiel. Významný negatívny vplyv na rast výroby automobilov má ťažba zdrojov, ktorá prináša niekoľko environmentálnych problémov, ako je vyčerpanie zdrojov, neudržateľnosť životného prostredia, ktorá vedie ku globálnemu otepľovaniu, a zdravotné problémy spojené s ťažbou zdrojov a výrobou automobilov. Ak sa má udržať úroveň používania automobilov, hlavným riešením je zamerať sa na recykláciu a výrobu ekologických vozidiel. Výskum recyklačných metód moderných vozidiel a ich analýza je zameraním tejto bakalárskej práce, ktorej konkrétnym cieľom poskytnúť náhľad rôznych typov recyklačných postupov. Prvá časť sa zaoberá všeobecnými princípmi recyklácie a recykláciou vozidiel po častiach. Následne práca presúva svoju pozornosť na obnoviteľné zdroje a ich využitie v automobilovom priemysle (elektromobily) a recykláciu moderných automobilov vyradených z prevádzky. Posledná časť prináša bližší pohľad na možnosti skladovania energie z obnoviteľných zdrojov, špecificky na vodíka (H2), jeho využitie v palivových článkoch, recykláciu vodíkových automobilov a budúcnosť pohonu. Práca konzultovaná s expert inžinierom danej oblasti.
On-line calculators for the design of renewable energy installations
Ondráček, David ; Pospíšil, Jiří (referee) ; Linda, Jakub (advisor)
This thesis focuses on the field of renewable energy sources (RES). It focuses on the topic of computational tools that manage the design process of a system using RES. These tools are introduced, their calculation methodology is described and then they are evaluated. As a part of this thesis there is also introduced a design of a unique calculation tool. This tool calculates the energy balance of a dwelling using solar energy and a heat pump.
Seasonal variation in renewable energy supply
Rymešová, Lucie ; Škorpík, Jiří (referee) ; Linda, Jakub (advisor)
This bachelor’s thesis focuses on seasonal fluctuations in energy supply from renewable sources, specifically photovoltaic and wind power plants. It includes a literature review on renewable energy sources and their importance in the energy sector. It further explores the principles and utilization of photovoltaic and wind power plants. The thesis analyses seasonal fluctuations in energy supply by processing data from the ČHMÚ station and examines their impacts on the energy system. The results of the analysis of seasonal fluctuations are presented and compared. It is evident that solar energy has the largest share during the summer months, while wind energy has the highest contribution during the winter months. The results suggest that a suitable combination of photovoltaic and wind power plants could suppress seasonal variations in electricity supply and contribute to its stable production within smaller energy units.
Design of an integrated self-sufficient residential house
Klouda, Jan ; Jaššo, Kamil (referee) ; Libich, Jiří (advisor)
The thesis deals with the design of an integrated island system for control and power supply of a residential house. The aim of the thesis is to develop a design for this self-contained islanded power supply, and to evaluate the proposed system from different perspectives. The thesis is divided into two parts. The first part is made by researching the possible solutions of a self-sufficient power supply for a residential house. This research contains mostly available technologies in the Czech Republic, and deals only with the domestic market. In the first part, different relevant methods of electricity generation, processing and storage are described. Then, the different technologies are described in detail and compared in order to achieve the highest possible economic, environmental and social compatibility. In the second part, the different technologies are implemented on the defined house to create a design for a self-sufficient house. This design includes several simulations and the selection of the most appropriate technologies. The resulting design is also compared with an already built self-sufficient house.

Design of a photovoltaic power plant on an industrial building to reduce energy consumption
Pospíšil, Filip ; Vaněk, Jiří (referee) ; Jandová, Kristýna (advisor)
The master thesis addressed the issue of reducing energy demand. The aim was to design a photovoltaic power plant for an industrial building, which will reduce this energy consumption. During the work, several simulations of different proposed photovoltaic systems were created and compared with each other, and the most suitable design was selected based on the input aspects. The theoretical background of the thesis has been used, which is described in the first two chapters. The thesis is supplemented by the calculation of the energy performance of the building, the project documentation of the chosen design and the analysis of the possibilities of how the surplus energy produced by the photovoltaic power plant can be utilised. Subsequently, an evaluation and conclusion are made.
