Sustainable Development Goal 7: Affordable and Clean Energy Panel Data Analysis
Křížková, Alžběta ; Cahlík, Tomáš (advisor) ; Moravcová, Michala (referee)
This thesis analyses the seventh Sustainable Development Goal: Affordable and Clean Energy. Four empirical models are built, each for one indicator. They are then evaluated using panel data analysis for all member states of the UN. The research question it seeks to answer is: "What characteristics have major impact on providing electric energy and other energy related benefits?" We found that in most of the cases, the proportion of urban population and the Human Development Index have a major impact on the indicators. Unlike any previous study dealing with similar topics, this paper analyses the whole goal with its four indicators, not just one particular energy aspect. That allows us to look for interconnection and common features between indicators and their influences.

Generation of Energy Using Renewable Resources
Vrbka, Martin ; Langerová, Petra (referee) ; Froehling, Kenneth (advisor)
Tato bakálářská práce se zaměřuje na výrobu elektrické energie za pomoci obnovytelných zdrojů. Existuje nespočet faktorů vztahůjících se k obnovitelné energii. Nicméně na tyto aspekty je většinou pohlíženo spíše individuálně, než jako na celek. Tudíž se tato práce pokouší obsáhnout většinu významných aspektů jež jsou spojeny s výrobou energie za pomoci obnovitelných zdrojů a organizuje je v jeden logický celek. To je uskutečněno představením obecného popisu technologie jako takové stejně jako výsledných dopadů použitých systémů.

Pěstování vybraných druhů rostlin pro energetické využití
ŠVEC, Miroslav
This diploma thesis on the topic "Cultivation of selected plant species for energy use" in the first chapters of the theoretical part deals with Czech and world energy. The chapters on renewable energy sources and the possibilities of using biomass for plants for energy purposes follow. The research also deals with grasslands as alternative energy sources with a focus on direct burning. The last chapters of the research are focused on the cultivation of selected energy crops, such as the Elymus elongatus grass (subspecies Ponticus, Szarvasi-1) and Miscanthus × giganteus. The practical part describes the establishment, nursing and harvesting of small-scale experiments of Szarvasi-1 grass and Miscanthus × giganteus grass varieties, which were cultivated on the premises of the University of South Bohemia in České Budějovice and were grown as energy crops for direct incineration. Experiments with the Szarvas-1 cultivation took place in three types of farming. The first variation was the so-called "extensive" form where the plants were not fertilized with any fertilizer. The second form of farming was the "intensive" variant, in which the fertilizer was fertilized with mineral fertilizers. The last variant labeled "digestate" was fertilized with organic fertilizer. Maloparcelian experiments with Miscanthus × giganteus were carried out only in one variation of cultivation than Szarvasi-1, "intensive". For both varieties of energy crops harvested in spring 2013 and for all cultivation variants, the yield potentials from the last five years of vegetation of these cultures were evaluated after a six-year vegetation period. The evaluated parameters were in particular the yields of fresh matter and dry matter in t ha-1, but also the average solids content in %. These results were recorded and compared with specialist literature. The results of the work show that Miscanthus × giganteus yields on average higher yields than Szarvasi-1, which surprisingly best responds to organic fertilizer fertilization.

Development of the phenomenon of renewable energy sources and their support in the Czech Republic
Hamzová, Kateřina ; Kaczor, Pavel (advisor) ; Noskievič, Pavel (referee)
The introductory part of the thesis deals primarily with the use of energy in the history of human society. The paper presents not only different types of renewable resources but also explains some important facts about these resources. The main objective of this paper is to quantify the level of financial support for renewable energy sources in the Czech Republic by 2016, with a forecast for 2020, and to analyse the impact on the price of electricity for the end customer. The paper shows a clear picture of individual payments of consumers for electricity consumption in Prague using the three most common tariffs of PRE, jsc. A partial objective is to map the historical, legislative and political developments in the field of renewable energy sources in the EU and the Czech Republic. The paper describes different support possibilities for renewable energy sources including related subsidy for the energy sector. The final part of the paper focuses on overall evaluation of the current situation of renewable resources and gives proposals for change.

A family house isolated by heystacks from point of view of ecological impact on enviroment and its residents
ŠOCH, Rostislav
One of the economical growth indexes is building and reconstruction of flats and family houses. Simultaneously with this growth of number of real estates there is effort of the highest possible energetic saving of houses. Goal of this bachelor thesis was evaluation of family house building isolated by heystacks with conventional buildings. For evaluation were used data of power consumption in particular dwellings in years 2013, 2014 and 2015. For idea: temperatures in these years were written down. These very warm years helped saving especially of houses with thermal pumps,which work with the highest heating factor for heating of warm water for normal use in summer months. From comparing of results from different points of view, the best resulted the house isolated by heystackcs. Contemporary development confims this result.

Renewable Energy Sector in The Republic of Serbia: Constraints in Renewable Energy Market Development
Drobnjak, Marina ; Svoboda, Karel (advisor) ; Šístek, František (referee)
This thesis analyzes the challenges associated with the countries in socioeconomic and political transition when on the path of integrating into the developed world unions or on the path of fulfilling projected renewable energy targets. As an example country, or as a study case here, The Republic of Serbia has been selected. The thesis addresses the question of how the Renewable Energy Market in Serbia is developing and how are the challenges being addressed. Thesis reveals that main obstacles come from the ownership of the energy and the power gird assets which are still entirely owned and controlled by the State. Due to this fact it is hard to introduce the planned renewable projects, mostly to be developed and owned by foreign entities, and at the same time to be forced to reduce domestic power production out of the thermal power plants. However, by being on the path to the EU, the renewable energy targets and the RES (Renewable Energy Sources) market have to be accomplished and the government has to show full legislative and policy support. It is also realized that there is a significant discrepancy between the "say and do" in the case of The Republic of Serbia, at least so far. The thesis highlights the important driving factors that, despite of the local resistance and sluggishness,...

Willingness to pay for green electricity
Novák, Jan ; Ščasný, Milan (advisor) ; Gutiérrez Chvalkovská, Jana (referee)
We estimate the willingness to pay for electricity generated from renewable energy in the Czech Republic. Discrete choice experiment is used to elicit preferences for various attributes of renewable electricity support scheme (PM emission, GHG emission, size of RE power plant, revenue distribution, and costs). Original survey is carried with 404 respondents living in two regions - Ustecky (polluted area) and Southern Bohemia (cleaner area). We find that respondents prefer decentralized renewable electricity sources over centralized, local air quality improvements over reduction in greenhouse gas emissions. Estimated marginal willingness to pay for 1% reduction in emission of particulate matter equals to 49 CZK, respectively 3.7 % of average monthly electricity bill. In total, WTP for green electricity is larger than current compulsory contributions to renewable energy support scheme. Powered by TCPDF (www.tcpdf.org)
