Support of the energy sources construction for households
Stručovský, Aleš ; Radil, Lukáš (referee) ; Bartošík, Tomáš (advisor)
This bachelor thesis deals with the comparison of energy sources used for residential construction. It focuses on photovoltaic power plants, wind power plants, hydropower plants and cogeneration units. Budget cost of energy source is limited to the amount of 550 000 CZK. Every source of energy is defined by its feature, operating principle, advantages and disadvantages. Options of selling the produced energy and its price are specified. Furthermore, the particular building licence applications (construction administration approval, generation of power questionnaire, application for connection to the distribution network, application for the contract of energy production support) including all the necessary enclosures have been analysed. Essential aspect for buying the energy source is its power and it is chosen according to the type of source. Energy source of hydropower systems is flow and gradient, in wind power systems it is wind speed, in photovoltaic power systems it is sufficient intensity of sunshine and in cogeneration units its dependance on annual heat consumption. Specific energy source available on our market is chosen for every group and the calculations of annual electricity production, period of repayment and profitability in 20-year running period are performed.

Possibility of using alternative decentralized energy sources
Pitron, Jiří ; Pěcha, Jiří (referee) ; Mastný, Petr (advisor)
The thesis concerns of the possibility by using alternative decentralized sources of energy. The first chapter describes current energy situation in the Czech Republic and consideration of future electrical energy consumption and the coverage by the renewable sources. Another part of this chapter describes each types of renewable energy with their advantages and disadvantages related to the Czech Republic. In the second chapter are introduced inputs which are appropriate for the plan of energetic system. The following theoretical chapter deals with each types of alternative energy sources using renewable source including the possibility of the installation and plan for the building. These alternative sources are sorted out by the way of using renewable sources of energy. The theoretical-practical fourth chapter concerns of the heating by the heat pump. For the detailed description was chosen the heat pump which is currently denote as appropriate alternative source of heat in household. With appropriate plan, which the thesis deals with, is this alternative source considered as proper investment. In the last chapter was assembled programme for creating models of energetic flux and calculation for the plan of heating by the heating pump air/water. This model is taken for concrete buildings related to exact outdoor temperature from previous years in concrete locality. In the end was realized validation of the software with the real measurement in concrete building.

Barriers of renewable sources expansion in the Czech Republic
Lukášek, Kamil ; Březina, Ladislav (referee) ; Mastný, Petr (advisor)
Currently, there is no publication that concerns the renewable resources comprehensively in the Czech Republic. This publication defines the renewable resources in general meaning. Whereas the physical and legal definitions of the renewable resources are different, text explains the principle of production of electricity according to the legal definition. When the renewable resources are being constructed, it's important to achieve the optimal operating conditions. To achieve these conditions, it's necessary to locate the renewable resource in the Czech Republic. The operations of renewable resources are partly financed by the country, in order to be more interesting for the investors. Further on, the conditions of connection to electrical distribution system are defined. The impact of renewable resources on electrical distribution system. Finally the conception of renewable electrical energy resource for region of East Bohemia is designed.

The Conversion Efficiency of Different Kinds of Energy into Electrical Energy and the Possibility of its Accumulation
Ostruška, Jan ; Bartošík, Tomáš (referee) ; Macháček, Jan (advisor)
The thesis deals with the issues of the conversion efficiency of different kinds of energy into electric energy. Firstly, the thesis presents a brief introduction into types of energy sources and their capacity. Then, conversion efficiency of particular direct and indirect conversion is scrutinized, pointing to factors which affect conversion efficiency. The next chapter deals with the possibilities of accumulating electric energy. These are analysed as far as conversion efficiency is concerned as well and the end of the chapter concludes with comparison of these particular possibilities. Booth parts of the process – power generation and its accumulation – are connected in comprehensive scheme of energy conversions. The thesis develops on this scheme by mathematic description of its components and by designing a simulation programme, which would show the flow of energy in the scheme.

Wind power plants principle
Polcsák, Jakub ; Fialová, Simona (referee) ; Pochylý, František (advisor)
The aim of the bachelor thesis is to elaborate the most extensive search, which deals with the description and function of existing wind turbines / pumps and their use in connection with water tanks. Wind turbines are divided by size. I have dealt with their principle of functioning, economy and properties. Next, I devoted myself to the future of wind farms. I have described their principles of functioning and properties. The last topic was dedicated to water tanks. In the first part I described their placement against the consumer, construction and use. The second part deals with their connection with wind turbines / pumps and their efficient use.

Wind power plant in area North Moravia
Pasírbková, Adéla ; Zmeškal, Oldřich (referee) ; Kotlík, Josef (advisor)
This thesis deals with analysis of wind parks from aspect of EIA, the annual capacity factor and the economy of operation. It shows the utilization of wind power in wind plants, wind potential of the Czech Republic and criteria for selection locations for construction wind plant. It describes the Act No. 100/2001 Coll., on environmental impact assessment, in which is the EIA process regulated. It analyses potential and real possibilities of wind power utilization in the North Moravian Region in connection with the Territorial Energy Policy.

Comparative Analysis of Renewable Energy Sources in the Selected European Countries
Konečný, David ; Borecká, Marcela (referee) ; Ellederová, Eva (advisor)
Cílem této bakalářské práce je poskytnout informace o obnovitelných zdrojích energie v Německu a v České republice, a to zejména z pohledu historického vývoje, energetické politiky, využití a možností dalšího rozvoje těchto technologií. Po shrnutí klíčových událostí a smluv s přímým vlivem na obnovitelné zdroje, práce analyzuje danou problematiku v Německu včetně energetické transformace této země, nazvané Energiewende. Stejná metodologie je použita při analýze obnovitelných zdrojů energie v České republice včetně srovnání finanční podpory obnovitelných zdrojů v obou zemích. Práce je zakončena kapitolou o vlivu, dopadech a možných důsledcích německé energetické přeměny na energetický sektor České republiky.
