Trends in renewable sources and in modern energy
Kotas, Tomáš ; Preisler, Lukáš (referee) ; Kudela, Libor (advisor)
The bachelor thesis deals with the issue of renewable energy sources. Renewable energy sources are categorized and extensively described, including the principles of their functions and basic parameters. The thesis further focuses on the development of the position of renewable energy sources over the years compared to non-renewable energy sources worldwide and in the Czech Republic. This development is monitored in terms of both electricity and heat. Statistics indicate that the share of renewable energy sources in both forms of energy is increasing. The thesis also analyzes the origin and course of discussions related to this issue, including climate change and international cooperation. Possible predictions and specific scenarios related to the energy vision are provided for both the Czech Republic and on a global scale within the thesis. All scenarios agree on the same future trend – an increasing share of renewable energy sources at the expense of non-renewable sources. In conclusion, the thesis addresses current trends in technologies in modern energy, with the most significant technological progress in recent years observed in the fields of electromobility, hydrogen, and CCUS. The final chapter discusses methods of energy storage.

Multirotor wind power plant for the Czech Republic
Boršoš, Adam ; Linda, Jakub (referee) ; Škorpík, Jiří (advisor)
As the power of wind turbines increases, the rotor diameter usually increases as well. This complicates transportation and handling. The multirotor power plant concept has the potential to minimise this problem. In this paper, various aspects of multirotor power plants have been described in general terms. The landscape of the Czech Republic has been analysed in terms of conditions for wind power plants and consequently a suitable site for the location of a multirotor power plant has been selected. This was followed by the selection of the wind turbine model for the multirotor design. After calculating the outputs and comparing the key parameters of the three models, the most suitable model was selected. This was followed by the actual design of the structure, which was created according to the results of the strength analysis in SolidWorks. Finally, a calculation of the dimensions of the equivalent single-rotor wind turbine was made and the corresponding model was selected. Also, the designed multi-rotor power plant was compared with the wind power plants surrounding the selected location.

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.

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.

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.

Wind power – the past, the presence and the future
Kučera, Vítězslav ; Klimeš, Lubomír (referee) ; Charvát, Pavel (advisor)
This Bachelor’s thesis deals with the evolution of wind turbines from the past to present and also concentrates on the evolution of wind turbines in the future. In first part the begin-nings of wind energy use are given, and the first wind turbine is mentioned. Further, the parts of wind turbine and its construction are described in next part, where the current state of wind turbines in the Czech Republic and in the world is presented. New concepts of wind energy are introduced. Finally, last part performs wind turbine simulation over the span of one year.

Utilization renewable energy sources inside of EPS Czech Republik
Zmeškal, Pavel ; Procházka, Zdeněk (referee) ; Matoušek, Antonín (advisor)
The purpose of this work was the analysis of current state and further development of renewable energy in the Czech Republic. And next their effects on the electricity system of the Czech Republic. On the basis of established facts has been developed actual state of renewable energy sources. The current situation is only orientation and is still changing at this time. Another objective was to evaluate the various renewable energy sources in terms of their impact on the electricity system and recoverability in the Czech Republic. In more detail were read up the conditions for the wind power plants operation and their connection to the electricity system of Czech Republic. In fine were discuss the impact of renewable energy sources on electricity system and prerequisite for their further development in the Czech Republic.

Center winery Nemcicky
Ondrová, Klára ; Velička, Jaroslav (referee) ; Dýr, Petr (advisor) ; Kalousek, Lubor (advisor)
This bachelor thesis deals with the design of Centre of Winery for the Modré Hory area. The proposed building should respect the surrounding environment, and attract tourists in the same time, by architectural form, urban planning and design. The plot for construction is located near the village Němčičky u Hustopečí on the hilltop of Nové hory. Currently, vineyards are being restored, which almost completely cover the whole area. The object of the wine center includes a canteen for tourists, a tasting room, a cellar for storage of bottles and technical and hygienic facilities. Production component is it's own electric energy cumulator. Using a renewable wind source. Part of the proposal should be the overview tower, making the site more attractive. The object does not process grapevine, it only archives bottles and works as a showroom and stop at a wine-growing cycle path. It has a simple rectangular ground plan with a sloping roof to cover the entry part and to shield the large glazing. On the ground floor there is a café with a background, a tasting room, hygienic facilities, a brick cellar and technical rooms in the basement. The facade of the building is covered with Siberian larch wood. A viewing tower is located at the west side of the building, almost at the top of the hill. The tower has a cylindrical shape and measures almost 14.5 m. It is also clad with wood of the same type. The production of electricity is provided here by 9 vertical wind turbines located along the northern boundary of the building on the artificial wall.
