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.

Oil as energy source
Maršík, Jaroslav ; Hrnčířová, Michaela (referee) ; Pospíšil, Jiří (advisor)
This bachelor’s thesis should give a complex overview about petroleum. The thesis is addressed especially for general public. It is divided into six parts; the first part describes a general introduction into how and where oil arises and what basic types exist. The second part focuses on oilfields; from their discovery through oil wells and their construction to extraction of oil. The third part deals with modes of transport and storage; so it was summed up in the topic The oil logistic. The fourth part describes an oil use, which we understand as an energy source. The fifth part summarizes the present meaning of oil and what oil is able to cause. And the last part is about oil future supplemented by the own comment.

Actual State and Potential of Renewable Sources Utilization in the EU
Kubín, David ; Radil, Lukáš (referee) ; Macháček, Jan (advisor)
This bachelor’s thesis named Actual State and potential of renewable sources utilization in the EU offers a detailed summary of the current and future utilization of renewable resources in each member state of the European Union. The opening chapters briefly introduce the term renewable resources and the legislation relating to this issue. The following chapter is devoted to a detailed background research of actual renewable energy utilization in all twenty seven member states of the European Union. The countries are ranked by their dates of accession to the Union in ascending order, in each chapter alphabetically. All information and data are obtained from reliable sources such as annual energy reports of ministries or institutions which are concerned with energy issues. This chapter contains a great amount of charts and tables taken from annual reports and which are revised for the needs of this thesis. The chapter named Potential of renewable energy utilization in the EU offers an insight into the assumed future utilization of renewable resources up to the year 2020. This chapter draws from so-called National renewable energy action plans (NREAP) in which each member state presents its plan leading to higher renewable sources utilization in the near future. The reader is therefore able to familiarize with plans concerning renewable sources in each member state. The chapter named Complex evaluation familiarizes with some pros and cons concerning renewable sources and their utilization. Further the author presents his point of view on renewable sources and some recommendation leading to a better integration of renewable sources into energetics.

Renewable energy sources: are they always contributive to the environment?
Pelz, Václav ; Jašková, Jana (referee) ; Baumgartnerová, Alena (advisor)
Semestrální práce se zabývá obnovitelnými zdroji energie a jejich využitím. Snaží se přiblížit i laickému čtenáři základní principy fungování obnovitelných i neobnovitelných zdrojů a výrobu elektřiny s tím spojenou. Snaží se zároveň poukázat na mnoho otázek a problémů s obnovitelnými zdroji se kterými se v dnešní době potkáváme, jelikož poptávka po elektřině stále roste, a přírodní neobnovitelné zdroje jako je ropa či uhlí pomalu ale jistě mizí. Nastiňuje základní problémy s obnovitelnými zdroji a uvádí klady a zápory jejich využití i do budoucna.

Vliv vybraných proměnných na trh s kryptoměnami
Doležal, Daniel
Doležal, D. The impact of selected variables on the cryptocurrency market. Diploma thesis. Brno: Mendel University, 2023. The thesis deals with the selection of individual factors and the subsequent identification of whether or not these factors have an influence on the development of the price of Bitcoin. The variables are selected based on scientific articles that deal with this issue and subsequently are subjected to regression analysis. The analysis itself focuses on the period from the last Bitcoin halving, i.e. on those variables that could have potentially influenced the development of the price of our asset in the last approximately three years. The focus is on the general influence of explanatory variables that influence the price of Bitcoin, but also on a comparison of the significance and nature of the influence of individual determinants on the second largest cryptocurrency by market capitalization, Ethereum. The results of the work are critically evaluated with scientific articles and recommendations for investors are made based on the information obtained.

Ropné havárie: vliv na životní prostředí a vývoj environmentální politiky
Pačovský, Jakub
This bachelor thesis deals primarily with oil accidents and the environmental policy associated with them. The aim of the thesis is to analyze oil accidents in terms of causes, consequences and environmental policies. The focus is on policies that try to minimize oil pollution. The partial aim is to analyze and compare these aspects on two specific accidents in the USA: Exxon Valdez and Deepwater Horizon. The first part of the thesis focuses on a general description of the oil industry, to put the issue into context. Next, the thesis comprehensively analyzes oil accidents and established global environmental policies that combat oil pollution. In the second part, the specific aspects are compared within the two mentioned accidents. In these specific examples, the impact of environmental policies is also assessed, according to the evolution of the amount of oil pollution over individual years. In the last part of the paper, the established facts are evaluated, when environmental policies prove to be crucial for combating oil accidents.

South Sudan's border formation process: the case of Abyei
Porubčanová, Lenka ; Mičko, Branislav (advisor) ; Doboš, Bohumil (referee)
The Sudan-South Sudan boundary has been the flashpoint of long-standing disputes between the two states. The most volatile area, however, is the oil-rich territory of Abyei. In the complexity of the localized zone, it is not only oil that forms the basis for the intractability of the two state's territorial disputes. This thesis aims to apply a newly developed theory of boundary formation that conveys broad insights into the possible drivers and factors of the border's state, not only in its technical definition. To this end, the thesis monitors some of the most influential factors compared across chronological periods. In such a mechanism, the thesis concretizes the state of the frontier by the selected structuralist theory. The extract further suggests a bidirectional relationship between the influence of state apparatus and border populations on the final borderwork. Therefore, the reflexivity of the population equally contributes to the border's state. This result demonstrates the theoretical model's broad applicability and a multidisciplinary explanation of the local border dispute fixation. Despite the limited scope, and hence the casual relationships examined, the thesis contributes to the debate on the stimulus for Abyei's territorial boundary tensions to some extent.
