Nuclear energetics in CR and in the world
Peroutka, Tomáš ; Bartošík, Tomáš (referee) ; Mastný, Petr (advisor)
This work is about a basic principles of nuclear reaction, creation of nuclear reaction and its development. Here is also described contemporary status and its level of progression. The first part is about a history of nuclear energy – its beginnings and further progress. Next the work deals with a nuclear power stations, nuclear reactors etc. The other part of this work is based on a nuclear waste. Then, I will write about a future of nuclear energy. The last point is creating the enegetic conception of our country.

Energy use of biomass
Ošťádal, Michal ; Elbl, Patrik (referee) ; Baláš, Marek (advisor)
The main aim of this bachelor thesis is to search for technologies for biomass conversion with subsequent energy utilization. At the beginning of the work is analyzed the nature of biomass as an energy source. The next part deals with individual technologies. The following section deals with combustion and biogas chains. The penultimate chapter deals with chosen energy sources. The last chapter is statistical processing of emissions, mining, electricity and heat production from renewable sources and biomass.

Renewable energy sources from oceans
Krišková, Mahulena ; Froehling, Kenneth (referee) ; Sedláček, Pavel (advisor)
Obnovitelné zdroje jsou v dnešní době velmi diskutované téma především kvůli vyvstávajícím problémům v rámci ekologie a úspory energií. I přes nejvíce zastoupenou část v této oblasti vodními, větrnými a solárními elektrárnami, se tato práce zabývá méně vyvinutou formou čerpání energie pomocí obnovitelných zdrojů, a tím jsou energie z oceánů. Příbojové a přílivové technologie jsou dvěma základními možnostmi, jak efektivně získat určité množství energie. V úvodu jsou popsány jednotlivé možnosti obnovitelných zdrojů a jejich zastoupení v rámci produkce elektřiny. Především jsem se však zabývala jednotlivými typy elektráren a na jakých principech fungují. Výsledkem je shromáždění informací o využívaných metodách v oblasti oceánské energie, spolu s nejvýznamnějšími elektrárnami světa.

Hydrogen fuels
Tyagunova, Victoria ; Bébar, Ladislav (referee) ; Jícha, Jaroslav (advisor)
This thesis presents a basic review of production and use of hydrogen fuels. The main focus of this paper is the use of hydrogen in industry and power engineering. The first part concerns various industrial production technologies. The next section is dedicated to the description of hydrogen use for energy conservation, fuel cells, power plants and combustion engines. it includes the comparison of hydrogen and classic fuels. The final part focuses on the economy and costs of hydrogen production and use. This paper will evaluate hydrogen as a potencial fuel for future and will estimate it’s advantages and disadvantages in comparison with conventional fuels.

Comparison and classification of ecological impacts of different types of power stations
Kunc, Dominik ; Bartošík, Tomáš (referee) ; Mastný, Petr (advisor)
The main subject of this work is to compare the ecological impacts of different types of power stations, to describe the possibilities how to reduce some of their harmful effects, and to design a cleaner electricity production process. Firstly the summary of this paper structure is introduced and the choice of its subject is explained. The second part describes the structure of energy mix in the Czech Republic in 2009 and in the following subheads there are defined basic principles of the particular power stations’ functioning, harmful effects rising during their operating and their impacts on people and the environment. There is the evalution of the power plants that created the indispensable amount of electric energy in 2009, which are: thermal power stations (mainly coal-fired ones but also the power plants burning biomass and the gas power plants), nuclear power plants, water power plants, wind power plants and solar power plants. Further there is mentioned the economical demand of energy generation from various sources and thein potential in our country in the next years. In the following part is focused on the possibility of reducing harmfulness in present electricity production, to the reduction of carbon dioxide emissions. It briefly describes the influence of this greenhouse gas on warming of our planet, what methods of capture carbon dioxide are recently available, what are the principles of these methods and what are the possibilities of carbon dioxide storage and transportation. Then we sum up economic demands of power production in the relation to useage of these technologies in various types of power plants. Likewise the possibilities of their realization in the Czech Republic are discussed. At the end of the second chapter we estimate the change of energy mix in the Czech Republic as a possible reduction of detrimental effects created by electric power production. In the third part we classify and compare these harmful impacts. Last chapter is focused on the evaluation of our energy mix estimation.

Optimalizace pojištění větrného parku Pavlov I.
Šebela, Miloslav
This bachelor thesis is dealing with the insurance of wind power stations and showing possibilities of the wind farm insurance on a practical example. There are introduced the most common forms of electricity produced from the alternative sources in the Czech Republic in the recherché part. There is an extended section dedicated to the wind energy. The practical part is concerning the insurance of the wind turbines, investigates possible risks and the most common causes of indemnities. There are different offerings of the insurance companies to insure the wind farm Pavlov I. evaluated further. At the end there is chosen the most suitable offer.

Production of electric energy in Czech republic
Skružný, Matouš ; Grosz, Jan (advisor) ; Köppelová, Jana (referee)
This Bachelor thesis deals with the production of electricity in the Czech Republic. The search part is focused on describing the different sources of electricity production and the characteristics of the sources in the Czech Republic. In the practical part is sequentially compared the total electricity production in the Czech Republic and the EU per capita, compared to European countries, according to the sources of production, comparison of electricity prices in Europe for households and industrial enterprises and other comparisons in the field of energy in the Czech Republic, the EU and other European countries. Furthermore there is verification of the renewable and nonrenewable sources electricity by using the correlation coefficient. The last part is the forecast of electricity production in the EU, using time series analysis.
