Hydro power station design
Novák, Pavel ; Grepl, Robert (referee) ; Ondrůšek, Čestmír (advisor)
This thesis deals with designing a small hydraulic power plant, where a swirl turbine is conected to a unique synchronous working, which will offer a reliable and easy installation of the hydraulic power plant. As a result a wider potential of energy could be produced from renewable resources. The use of a narrow rottor as a holder of the permanent magnets is the biggest difficulties of this design.

Negative impact of renewable energy sources
Kleinová, Martina ; Lachman, Jakub (referee) ; Sitek, Tomáš (advisor)
The main focus of this work was to delve deeper into the issue of renewable energy. Firstly, we have looked at the different types in general and their characteristics, but in particular we have focused on the negative impacts they bring. Since renewable energy sources are our future, it is necessary to become familiar with their potential, possible shortcomings, the degree of severity of these problems and possible solutions. In the last part of the thesis, we looked at the use of renewables in the Czech Republic and evaluated the current policy and energy market.

Design of industrial boiler with cogeneration
Mička, Radek ; Tvarůžek, Martin (referee) ; Křenek, Ladislav (advisor)
The diploma thesis deals with the design of the industrial boiler for biomass, Which deals with the issue of the energy future of combustion of fuels using current power generation - microcogeneration, designed for larger houses or smaller com- panies. The shape of the device is the interconnection of individual functional and technological parts of the boiler, a view of a new product that re ects its function. It uses modern and timeless materials, color and control technology to achieve overall comfort and time savings and service.

Real potential of renewable energy sources in Czech republic
Tofel, Jan ; Kropáč, Jiří (referee) ; Máša, Vítězslav (advisor)
The aim of this thesis is to present the basic characteristics of renewable energy sources and assess their potential for further use in the Czech Republic. Based on studying literature, statistics, foreign experience and consultation with experts is reviewed which of these resources in the Czech Republic give meaning or how to ensure their effective use. The individual chapters of the thesis describe in detail the characteristics of renewable energy and in the final chapter are reviewed economic and environmental terms.

Electric boiler connection in heat plant for providing ancillary services
Ditrych, Marek ; Příhoda, Martin (referee) ; Wasserbauer, Vojtěch (advisor)
The bachelor thesis deals with using the electric boiler for extension ancillary services in heating plant. The system and support services are described in the thesis, because the ancillary services regulate an energy deflection. The system and ancillary services are described in the thesis. Thanks to these services an energy deflection is regulated. The thesis describes different types of electric boilers and there functions. In the thesis is shown the possible solution of using an electric boiler in heating plant Opatovice. The cable conduction is designed for a power of electric boiler. For this reason, there is calculated the equivalent warming short-circuit current close to the electric boiler.

Office building
Výborný, Vojtěch ; Stránská, Zuzana (referee) ; Struhala, Karel (advisor)
This master´s project deals with design of an office building nearly zero energy standard. My master´s project consists of three parts. In the first one I work on technical design of the office building. It is a three-storey building with partial basement. Vertical load-bearing system is partially made from monolithic concrete walls and partially from clay blocks walls. The horizontal load-bearing structures are made of monolithic concrete slab. All roofs are designed as flat roofs. In second part I design all technical equipment in this building. In the last part I compare three types of roof, photovoltaic power plants and evaluate their environmental impact. First type of PV power plant is made by monocrystalline solar cell, second one by polycrystalline solar cell and last one by monocrystalline solar cell with battery system. Environmental impact of these systems is evaluated in Open LCA software. All structures comply with the valid standards and regulations.

Compare prices of electricity from nuclear power and renewable energy sources
Sláma, Miloslav ; Varmuža, Jan (referee) ; Radil, Lukáš (advisor)
This work deals with the components that that creates price of electricity and the regulation of electricity prices. It explains methods of regulation, setting electricity prices. It examines the factors that affect it. It also deals with the calculation of the price of electricity from various energy sources. It studies Support RES system, the conditions for obtaining and statistical data on development aid. It adds alternative sources of energy and their future and security.

Solar energy storage
Řehák, Pavel ; Pospíšil, Jiří (referee) ; Poláčik, Ján (advisor)
This thesis aims to find solution that deals with excess energy produced by solar systems. Main point in this Bachelor's thesis is to solve off-grid solar power system that is completely self-sufficient. Introduction examines how solar panels works and the best weather conditions of operating. Analytics part of this thesis focuses on basic information about types of power accumulation with their advantages and disadvantages. Practical part proposes system used and also mathematical solution of solar system.

Energy Evaluation of Technical Services Systems
Cap, Petr ; Horák, Petr (referee) ; Vendlová, Lucie (advisor)
This Master’s thesis deals with the energy evaluation of existing buildings sports-recreational company complex in Brušperk. For this purpose provides a comparison of selected fuels as an energy source for the heating in terms of economy and their impact on the environment. In addition, provides an overview of existing legislation for elaboration of an energy audit. To complement shows the calculation of return on investment in solar panels on the roof of one of the objects. Calculation is based on the results of performed experimental measurement. Finally, the thesis presents a comparison of energy performance of buildings simulated in the Bsim software with reality.
