Discussion of socio-geographic aspects of renewable energy sources in Czechia
Görcs, Jan ; Hána, David (advisor) ; Pulec, Jan (referee)
Discussion of socio-geographic aspects of renewable energy sources in Czechia Abstract Modern society is completely dependent on electricity supplies in every aspect of life and the economy. The task of every developed country is protection and ensuring sufficient energy in the required quality. Otherwise, the lack or interruption of supply may paralyze the country's life and economy. The current energy problem lies on the fact that it is based on non-renewable energy sources with limited quantity. In addition, they have a negative impact on the environment. Renewable energy sources also provide limited solutions to the situation. This bachelor's thesis therefore analyses the assumptions, possibilities and potential of the development of renewable sources in Czech electricity, in relation to the energy position, environment, electricity, society and economy. The aim of the thesis is critical evaluation of the pros and cons of the implementation of alternative energy sources in the energy mix. Key words: renewable energy sources, alternative sources of energy, energy mix, solar energy, wind energy, water energy
Heating with renewable energy sources
Oravec, Jakub ; Vyhlídalová, Karolína (referee) ; Horák, Petr (advisor)
The goal of this thesis is to design heating sytem and hot water preparation system in apartment building with use of renewable energy sources. Theoretical part is focused on solar thermal collectors and their technical attributes. Practical part contains design of heating system and design of domestic hot water preparation system. Transport of heating water is provided by two pipe heating system with forced water circulation. Pellet boiler is usead as a heat source and is also usead as a primary heat source for hot water preparation. At the same time secondary domestic hot water prepartion system was designed through the use of solar collectors.
Evaluation of possibilities of renewable energy sources application in selected objects of the CHMI
Kudela, Tomáš ; Sládek, Ivan (advisor) ; Kůla, Bořivoj (referee)
This bachelor thesis is dedicated to the use of renewable sources of energy in practice, namely in the Czech Hydrometeorological Institute (CHMI) objects, such as professional meteorological stations or observatories. The first part of bachelor thesis deals with the description of the alternative energy sources, the principles of acquisition and processing for the needs of the energy industry. The second part relates to devices already installed in CHMI objects and zooms technological solutions and experiences with the operation of these facilities. The third part presents a proposal for the use of specific devices for selected CHMI objects. Key words: renewable sources of energy, solar energy, wind energy, hydro energy, heat pumps, biomass, meteorological stations
Using solar energy in the framework of the European Union extended by a case study for the region of the Czech Republic
Kosánová, Kristina ; Matějíček, Luboš (advisor) ; Přibil, Rudolf (referee)
This bachelor thesis analyzes the current use of solar energy in the European Union member states, both in terms of photovoltaic systems and in terms of solar thermal systems. The amount of used solar energy is compared with the sum of solar radiation in given area, as the main indicator for the possibility of using solar energy. The thesis is based on the processing of various literary and online sources, which give a comprehensive view of this renewable resource. The second part is focused on the territory of the Czech Republic. The case study is based on maps. The result also contains a map created in GIS, which shows the areas with the highest solar energy income for the entire Czech Republic as well as for the selected part of Prague.

Solar kits and optoelectronic components in physics tuition
Burkovec, Václav ; Drozd, Zdeněk (advisor) ; Kolářová, Růžena (referee)
In my diploma thesis, there was created the summary of solar construcion, toys and another elements, which are available on the market. At first some construction were selected, than there were the experiments were drawn up and at the end the experiments were done by students dutiny the lessons.There is also a short movie including these experiment. The diploma thesis contains my own design of solar construction, the description of its manufactory and its use in teaching physics. There is also the description of accompanying website. On this website i tis possible to download the wokrsheets. These worksheets were tested dutiny the teaching and later than at work evalueted.
System Proposal for the Use of Low-potential Heat
Kučera, Roman ; Bartoň, Jan (referee) ; Mastný, Petr (advisor)
This bachelor thesis deals with the problematics of a low-potential heat from the energetics point of view. It also deals with the sources and subsequent use of the low-potential heat. First of all, the thesis mentions the origin of these sources and also describes where they can be found. Also the technologies, that are able to utilize this heat, like heat pumps and solar collectors, are mentioned in this part of the thesis. In its next part, the bachelor thesis deals with use of the waste heat for heating and production of electrical energy. In the last part, the thesis presents the project that introduces a specific concept of the system for object heating from the waste heat.
Analysis of a Photovoltaic Power Plant Operation
Šidla, Ondřej ; Borecká, Marcela (referee) ; Baumgartnerová, Alena (advisor)
Tato práce umožňuje náhled do problematiky fotovoltaických systémů a jejich využití pro výrobu elektrické energie, která hraje v dnešní době důležitou roli. První část je především zaměřena na charakteristiku vybraných fotovoltaických článků. Dále se práce zabývá legislativou v oblasti fotovoltaiky v České republice. Tato kapitola je pak dále rozšířena o kroky potřebné k realizaci fotovoltaické elektrárny. Závěrem je provedena technicko-ekonomická analýza konkrétní fotovoltaické elektrárny.
Design of Solar Garden Shower
Bajková, Eva ; Bukvald, Jiří (referee) ; Sládek, Josef (advisor)
The bachelor thesis is focused on design of solar garden shower. The work analyses current products, describes basic technical parameters and brings design solution. The aim of this work is to improve estetics with regard to ergonomics and functionality.
Possibile Use of Renewable Energy Sources in a House in the Village of Hovězí
Kašpar, Radek ; Daňhel, Petr (referee) ; Čech, Josef (advisor)
Diploma thesis The possibilities of using renewable energy sources in a family house in the village of Hovězí is divided into two parts. The theoretical part describes the types of renewable resources and the possibilities of drawing up the subsidy program Kotlíková dotace. In the practical part describes the object of the family house. For this house the necessary attachments were made for the possibility of drawing the Kotlýkové subsidy and the most suitable source of heat was chosen with the calculation of the costs of implementation and evaluation of the payback period.
