Modern Application for Household Heating
Šoupal, Filip ; Brázdil, Marian (referee) ; Lisý, Martin (advisor)
This bachelor thesis is focused on the research of basic sources, methods, and possibilities of heating modern family houses. The thesis is divided into three parts, the first one is focused on the advantages and disadvantages of individual heating sources in the use of renewable and non-renewable energy sources. The next section thoroughly describes and compares the methods of heating considering current emission standards. At the end, there is a technical and economic comparison of the variant of the current gas boiler with the variant of the automatic coal boiler and the modern heat pump. The comparison in interpreted on a model house through performed calculations. For better accuracy, the thesis is enhanced with pictures and tables.
Budování a provoz bioplynových stanic a jeho dopady na lokální rozvoj z pohledu obyvatel obce – případová studie Velké Albrechtice
Červenková, Ivana
Diploma thesis Building and Operation of Biogas Stations and Theirs Impacts on Local Development from the Perspective of the Municipality´s Residents – A case study of Velké Albrechtice deals with the impact of the operation of biogas stations in the municipality of Velké Albrechtice on local development from a perspective of local residents. As a part of this work, a questionnaire survey and analysis of biogas stations in the municipality were carried out. The theoretical part is based on an identification of energy sources and their division. More attention is paid to renewable energy sources, respectively to secondary energy sources. It also focuses on establishing of the concept of biogas plants, theirs functioning, advantages and disadvantages. In addition, it describes problems and conflicts with the establishment of biogas plants. The practical part of the thesis presents the case locality - the municipality of Velké Albrechtice and specific biogas stations. Additionally, it evaluates opinions and attitudes of the local population towards these stations both before going to production and at present. It also includes an analysis of the results of the questionnaire survey and discussion about it. The output of the thesis is a comparison of the situation in the initial period of conflicts and current problems with the functioning of biogas stations. Moreover, it inquires whether there have been any changes both from the perspective of residents and in the operation of the stations. Reasons of these changes are evaluated at the discussion of the thesis. Next, the most significant positive and negative effects of the construction and operation of the biogas plant on the life of the community and its development are identified. Last but not least, the thesis conclusion formulates recommendations that can improve the future development of biogas plants in the Czech Republic and can prevent conflicts between biogas plant operators and the local population in other locations.

Renewable resources of energy and their use in the Czech Republic
Kohútová, Alena ; Vošta, Milan (advisor) ; Antal, Jarolím (referee)
This diploma thesis is concerned with renewable resources of energy and their use in the Czech Republic. The first charter includes not only basic terms that will be used during whole the thesis but also a short description of non-renewable sources and detailed description of renewable resources of energy. The second chapter informs about the energy industry and it concentrates on the production of electricity and heat by renewable resources. Moreover, this chapter introduces install energy output of renewable resources in the Czech Republic. Third chapter is dedicated to financial aid heading towards renewable resources of energy in the Czech Republic and finally fourth chapter contains the case study, which is focused on the efficiency of investment payback of solar system installed on the roof of family house for gaining electricity. In the case study there is a comparison of several solar panels made by different producers and it is also compared the efficiency of investment payback for each solar panel. The case study is carrying out using method of collecting information followed by several calculations. The result of the diploma thesis is finding that the financial support for using renewable resources is adequate. Furthermore, the second finding is that investment to installation of the solar system to the roof of the family house is efficient in case of obtaining the financial aid.
The Impact of Renewable Energy on the EU Electricity Prices and CO2 Emissions
Čech, Marek ; Janda, Karel (advisor) ; Luňáčková, Petra (referee)
This thesis is focused on the topic of electricity pricing in the European Union connected with the increasing use of renewable energy sources in electricity production and consumption. It provides background information related to the types of energy sources along with the summary of their advantages and disadvantages regarding both the environmental impact and financial costs. Furthermore, it involves fundamental global and European electricity production statistics and a summary of the European Union approach to the support of environment-friendly energy production methods. The core of the thesis is then the econometric panel data model (data collected from 13 member states of the European Union over the period between 2010 and 2013) analysing two relationships. First, the impact of the share of renewable energy sources in the final electricity production on the European consumer electricity prices. Second, whether the replacement of fossil fuels by renewable energy causes a significant decrease in the greenhouse gases (specifically carbon dioxide) emissions. In conclusion, this paper provides suggestions for further research based on the analyses included in it.

This bachelor’s thesis focuses on optimization of electric energy consumption in household and its energetic independence. There is an overview of available energy sources for household and possibilities of its accumulation. Next, the function of system electrical wiring is described and compared with systems in today‘s market. In more detail, the thesis deals with description of FOXTROT control system developed by the company TECO a. s. and with possibilities of its application. The study describes savings optimization from both investment and operation perspective. A comparison of appliances of two energy classes in current prices is done, as well as a comparison of one-way and two-way pricing. Savings opportunities in lighting system, temperature control and appliance division according to their manageability are demonstrated. A calculator for photovoltaic system was created which provides return time of investment upon input parameters. A part of the thesis is a project documentation realized as a stage of a household object study, on which optimization opportunities are demonstrated.
Super Grids Conception
Chodura, Przemysław ; Prokop, Václav (referee) ; Paar, Martin (advisor)
Cílem bakalářské práce “Super Grids Conception” je poskytnout komplexní náhled na problematiku Super Gridů ve smyslu pozadí, konceptu jako takového, dostupných technologií, dosavadních zkušeností a budoucího vývoje, možných zdrojů elektrické energie a konkrétních konceptů a studií. V úvodu jsou osvětleny důvody vedoucí k potřebě elektrických sítí nové generace – celosvětové snahy snižovat dopad výroby elektrické energie na životní prostředí, rostoucí poptávka po elektrické energii a potřeba integrovat obnovitelné zdroje energie. Možné zdroje elektrické energie jsou diskutovány jak v širším kontextu, tak i ve smyslu současných omezení a budoucího vývoje. V druhé části jsou popsány koncepty Smart Gridu, Super Gridu a SuperSmart Gridu s důrazem na přínosy, základní principy a systémové hledisko. Autor se dále zabývá jen koncepcí Super Gridu. Použití stejnosměrných (HVDC) a střídavých (HVAC) technologií je porovnáno z technického i ekonomického hlediska a z něj vycházející typické použití těchto technologií. Dále je podrobně popsána nejlepší dostupná technologie HVDC systémů – základní principy a konfigurace, popis jednotlivých částí, omezení současných technologií, dosavadní zkušenosti a možný prostor pro další vývoj. Následuje zmínka nových výzev oblasti HVAC technologií ve vztahu k Super Gridům a popis problémů souvisejících s hybridními AC/DC linkami a koridory. V poslední části jsou vysvětleny rozdíly v historickém vývoji a současných postojích v různých částech světa. Zároveň jsou představeny koncepce zvažovaných Super Gridů. Zvláštní prostor je poskytnut vizionářské koncepci vytvořené DESERTEC Foundation a technickoekonomické studii OffshoreGrid.
