Bidmonová, Renata ; Velísková, Eva (referee) ; Hirš, Jiří (advisor)
The bachelor thesis deals with the energetic evaluation of the building in Brno. It is divided into three parts. Part A focuses on basic definitions and division problematics under applicable laws, decrees, and technical standards. Part B provides a more detailed description of the individual relationships and calculation procedures used to process the parts of the building's energy performance certificate. Furthermore, proposals for measures to improve the energy performance of a building, economic and environmental assessment. Part C contains a description of the object, its construction solution and the specifications of the BS (Institute of Building Services) systems. Furthermore, the calculation of energy needs for individual BS (Institute of Building Services) systems. Designing austerity measures for a given object. The main part of the bachelor thesis is experimental measurement and its evaluation.

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. JEL Classification H20, Q20, Q40, Q47, Q48, Q54 Keywords carbon dioxide emissions, electricity price, energy sources, renewable energy...

Energy independence and optimization of energy consumption with use renewable sources and smart wiring in house
Kaděra, Jan ; Hošek, Milan (referee) ; Bátora, Branislav (advisor)
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.

Hydro power station design
Novák, Pavel ; Grepl, Robert (referee) ; Ondrůšek, Čestmír (advisor)
This thesis deals with designing a small hydraulic power plant, where a swirl turbine is conected to a unique synchronous working, which will offer a reliable and easy installation of the hydraulic power plant. As a result a wider potential of energy could be produced from renewable resources. The use of a narrow rottor as a holder of the permanent magnets is the biggest difficulties of this design.
