Fermentation of biogas plants
Mrůzková, Karolína ; Vičíková, Magda (referee) ; Svěrák, Tomáš (advisor)
This bachelor thesis deals with the study of biogas plant technologies, mainly those based on the wet anaerobic digestion. In the experimental part of the thesis, biogas yield of the substrates (corn silage, corn hominy, pig slurry, poultry droppings, sugar beet pulp) is measured in a fermentation test. Based on the real biogas yields of a particular biogas plant, where the determined substrates are used, the relative error of the fermentation test was calculated.

Alternative energy sources
Stránský, Jaroslav ; Moskalík, Jiří (referee) ; Škvařil, Jan (advisor)
In this work, I tried to summarize the current state of world energy resources that we use to convert into electrical energy. There is solved the question of compensation running short supplies of fossil fuels and reduce discharge of greenhouse gasses. I´m looking for suitable compensation in department of alternative energy sources, among which I included the power of the Sun, water, wind, geothermal energy, using heat pumps, combustion energy, nuclear energy, fuel cells and hydrogen use. About anyone of replacing sources you learn about its history, advantages and disadvantages, the principle of function energy transform devices, and compare the potential that is available in the CR and in the world.

Innovation and Extension of Solar Concentrator system
Vasyliev, Mykola ; Radil, Lukáš (referee) ; Baxant, Petr (advisor)
The bachelor thesis is focused on the innovation and expansion of the solar concentrator system, which was originally created by Robert Hrachiar in 2016 [1]. The description and implementation of the concentrator system is given in the bachelor's thesis entitled Solar applications with concentrator elements. The bachelor thesis contains a description of basic knowledge for the operation of a solar concentrator system, analysis of the original project, identification of deficiencies and the relevant improvement of the concentrator system. The advantages of solar energy over other alternative energy sources and the principle of operation of solar systems with separate mirrors are described in the theoretical part. The analysis of the project and the identification of deficiencies in the section described the identified deficiencies that arose during 2 years of operation of the solar system. Investigation of the causes of deficiencies and negative consequences. The Modernization section contains a description of the relevant improvement of the concentrator system based on the identified shortcomings, innovation and expansion based on the experience of using a similar system in the country and in the world.

Design of a building using alternative materials with respect to the requirements for sustainable development
Dvořák, Jakub ; Remeš, Josef (referee) ; Žižková, Nikol (advisor)
This diploma thesis deals with the design of a small family house, which construction uses alternative building materials. The first part of the thesis is devoted to the world, European and Czech legislation related to sustainable development. The concept of ecological construction, which focuses on the possibilities of reducing the negative impacts of construction production on the environment at various stages of construction and on energy, material, water and waste management, is also presented. The thesis also describes advantages and disadvantages of particular solutions. In the second part of the thesis, which based on theoretical knowledge, is the design of a family house from alternative materials worked out. The design of the study in the scale of 1:100 consists of measured floor plan drawings of all storeys, characteristic measured section drawings, layout plans with displayed furniture and equipment, elevation drawings of particular facades, roof drawings and situation design. The drawing part is accompanied by a text part. The processed design is compared to the reference building and then evaluated from the point of view of functional, economic, environmental and social requirements.

Alternative energy sources in the selected region
NOVOTNÁ, Věra
This bachelor thesis is focused on the use of alternative sources in a selected region. More specifically, it deals with biogas plants in a selected region. The thesis is divided into theoretical part and practical part. The theoretical part contains general information, such as types of biogas plants, their general usage, their strategies, from which they draw material for energy production and where they invest this energy. The practical part consists of an analysis of the activities of biogas plants in the selected region. This analysis works with specific data on activities, strategies of specific biogas plants, their drawing subsidies or their plans for the future. The analysis includes interviews with representatives of selected biogas plants, from which the results of the survey outcome.

Legal regulation of the alternative sources usage in the Czech Republic
Hošek, David Jakub ; Žákovská, Karolina (advisor) ; Snopková, Tereza (referee)
This Master's degree thesis deals with the renewable energy sources regulation in the Czech Republic. It also mentions the European Union legislation on the topic and its development and focuses on the most important Directives and their goals as well as Member States' obligations. It presents Czech regulation in force and the conceptual documents in greater detail. It also points out the system of support available for the promotion in using the renewable sources of energy. Finally it examines the renewable energy sources of the small extent and the decentralized power generation as well.

Design of a photovoltaic power plant for a family house near Olomouc
Juřička, Dušan ; Maule, Petr (referee) ; Vaněk, Jiří (advisor)
The bachelor's thesis deals with the introduction to the components of a photovoltaic system and the creation of a specific photovoltaic system installed in a family house located north of Olomouc. The system is designed to meet the requirements of a family of four. Based on simulations and current market prices, the profitability of the entire system is evaluated. The financial return of the project and the possibility of a subsidy from the state are also considered. In addition, the future possibility of purchasing an electric car is included and the potential impact on the flow of energy within the internal power grid is simulated.
