Wind power plant
Šponiarová, Petra ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
The electricity production from renewable sources is a very current topic. It also includes the electricity made by wind power plants, which the bachelor’s thesis concentrates on. An extensive research study was conducted to provide an overview of wind turbine types. Concerning wind power plants, apart from their visual impact, noise and vibration connected to their operating is an often discussed issue. The construction of a wind turbine stands for the most important role in reducing such unwanted effects. Technical experiments following specific standards and recommendations are performed to assess the impact of wind turbines-emitted noise and vibration on humans. In order to assess noise and vibration of a wind turbine a technical experiment is proposed, which uses different approaches to determine the critical components. The selection of a suitable measuring equipment and the choice of location for its subsequent use are important parts of the design. At last, the use of wind power plants is critically reviewed.

Storage systems for renewable energy
Švácha, Filip ; Kracík, Petr (referee) ; Poláčik, Ján (advisor)
The aim of the thesis is to describe the current possibilities of storing electricity from renewable sources focusing on hydrogen technologies. In the first three parts, the question of energy sto-rage from renewable sources, the current energy storage options and the actual energy storage in hydrogen are discussed in the form of research. The last part is practical and its aim is to compare the current possibilities in designing a system that stores energy in hydrogen. Subsequently, the most favorable option is chosen and compared to other energy storage methods.

Alternative Energy Sources and Their Integration into the Concept of Smart Grids
Kopička, Marek ; Procházka, Jiří (referee) ; Baxant, Petr (advisor)
This work deals mainly with electrical energy. In the first part is focused on alternative energy sources, and describes structure of consumption and production of electricity over the past few years, during which is focuses on renewable energy sources. In this context, assesses the conditions for alternative energy sources in the Czech Republic from the perspective of the legislative, as well as current status and potential of alternative energy sources and tries to predict the development of these issues. The next section describes the Smart Grids as a means to achieve these goals. There are presented the basic features of this system, its goals and challenges, a description of the integration of Smart Grids with other sources of electricity and the benefits of using Smart Grids both from the perspective of user and from the perspective of system. Other parts are focused on distributed control systems in the energy sector, its development and principle. The last part is devoted to consideration of the role of alternative energy sources and distributed generation in Smart Grids.

Modernization of biomass heat plant.
Sedlák, Martin ; Fiedler, Jan (referee) ; Fiedler, Jan (referee) ; Skála, Zdeněk (advisor)
The thesis examines the suitability of a CHP project in Bystřice nad Pernštejnem, a small town in Vysočina region, Czech Republic, which is currently supplied by biomass central heating. It reviews situation and availability of renewable energy sources and opportunities for CHP both in the Czech Republic and in Europe, including the context of current global developments. The opening chapters are followed with the renewable energy project for Bystřice nad Pernštejnem itself. The current technology, availability of biomass fuel for a potential future project, and possible development of energy sources in the town are analysed. Three alternative solutions for the CHP plant are suggested, with proposal for the technology and economic analysis, and possible future steps of the town council are discussed.

Business Project in the Area of Renewable Resources of Energy
Kerndl, Michal ; Kallabová,, Eva (referee) ; Heralecký, Tomáš (advisor)
The aim of my thesis, which is called „Business project in the area of renewable energy resources“, is to analyze business opportunities in the area of renewable energy resources, which have been highly actual and discussed recently, whether in term of benefit for environment or in connection with international problem of shortness in energy resources. Result of this thesis is, on the basis of the analysis, to define recommendations in the form of optimal proposal for realization. The thesis is engaged in description of current state in the area of the renewable energy resources, their utilization in practice and consequential proposals for realization including project financial plan. The thesis is also engaged in possibilities of state budget and EU grants use.

Utilization of renewable energy sources in Czech Republic
Kopička, Marek ; Bok, Jaromír (referee) ; Matoušek, Antonín (advisor)
This thesis deals with consideration of energy facilities structure in Czech Republic. It is depicted in it their evolution from point of: electric energy consumption, structures of energy facilities and electricity prices. Further, is here depicted a production of electric energy for the year 2009, from the point of: produce, sources, consumption and ratio of factories. Of course, the RSE (renewable sources of energy) effect and share of scope on this evolution and structure, is also mentioned here. The next part is pointed to basic description of each sources of electric energy. It is not mentioned here only factories which uses for it´s production renewable primary sources but also another types of factories. Their pros and cons are also summarized. The last part of this work is a thought of realization of fictive project, which could replace a part of steam power plants' share by producing electric energy through renewable sources. It is re-counted and suggested here a few possibilities of this realization from the point of needed installed power and approximate estimation of capital expenditure.

Household cost analysis
Havránková, Denisa ; Aigel, Petr (referee) ; Výskala, Miloslav (advisor)
The diploma thesis deals with the analysis of the cost of a house in the area of peripheral constructions and the effect of thermal insulation on energy consumption for heating and hot water. The theoretical part generally defines renewable energy sources, heat sources, thermal transmissions and structural losses, basics of valuation of construction works and supplies and overview of state subsidies. In the practical part are proposed composition of peripheral constructions, calculation of heat transfer coefficient of all designed perimeter structures and their subsequent evaluation. Furthermore, there is an estimated annual energy demand for heating and hot water and annual electricity consumption in the household. At the end of diploma thesis is a proposal of suitable energy sources and calculation of the return on investment in these sources.

Renewable energy sources for one-family house
Burýšek, Jan ; Špiláček, Michal (referee) ; Fortelný, Zdeněk (advisor)
This Bachelor´s Thesis deals with the topic of Renewable Energy Resources. It is divided into two main parts. The first part is a research on renewable resources of energy which are available in the Czech Republic. The second part is focused on use of particular resources in a chosen object (house) and their subsequent efficiency evaluation.

Passive house
Majer, Filip ; Klubal, Tomáš (referee) ; Brzoň, Roman (advisor)
Bachelor’s thesis is focused on solving project documentation of new building of Passive building. Emphasis is laid on creating „airtight“cover of house which is achieved accuracy solutions to structural details, suitable selection of building and supplementary materials. An important factor in this issue is the massive use of thermal insulation materials. The project also focuses on the appropriate arrangement of renewable energy technologies and their applications.

Up-to-date technology for energy utilisation of biomass and waste
Krňávek, Martin ; Frýba, Lukáš (referee) ; Kropáč, Jiří (advisor)
The bachelor‘s thesis deals with technologies for energy utilisation of biomass and waste. The introductory part is dedicated to biomass, its division and sources of biomass suitable for thermal treatment. The main part describes and compares technological units for energy utilisation of biomass, which is important for the Czech market. Furthermore there is described selected technologies for flue gas cleaning suitable especially for thermal treatment of waste. A basic design calculation of technological unit fired with wood chips for combined heat and power production is included here.
