The influence of energy mix on environmental impacts of waste management
Dočekalová, Veronika ; Kočí, Vladimír (advisor) ; Trecáková, Tatiana (referee)
This paper presents energy mix of Czech Republic and its effects on environmental impacts of waste management. Three technologies: landfilling without energy recovery and landfilling and incineration with energy recovery are assessed using LCA. Results for 1 t of mixed municipal waste are compared in 9 impact categories: abiotic depletion, acidification, eutrophication, global warming, ozone layer depletion, photochemical ozone creation, human toxicity, terrestrial ecotoxicity, freshwater ecotoxicity. Landfilling without energy recovery was evaluated as the most harmful technology to the environment, incineration as the most environmentally-friendly one. The use of Czech energy mix made impacts of the energy recovery technologies look lower, contrary to burdens of landfill without energy recovery that resulted higher. The influence of energy mix composition change is discussed further.

Study of the ecology of electric vehicle
Varhaník, Jiří ; Jandová, Kristýna (referee) ; Jaššo, Kamil (advisor)
The first chapter of this bachelor's thesis describes the history of electric cars, their origin, success and decline at the time. The following chapter deals with the clarification of the carbon footprint with regard to the connection to other chapters in the field of ecology of passenger cars. The main goal of this thesis was to study the issues related to the ecology of passenger cars with a focus on electric vehicles in the Czech Republic. The~ecology of vehicles covers all periods of the car's life-cycle, starting with the production, following with utilization, final disposal and recycling of the vehicle. Another goal was to select and describe a suitable methodology for calculating the environmental impact of these vehicles. In the practical part, the relations and calculation methodologies were determined, data sources for individual parameters of these relations were obtained and the calculations were performed. The last part was about processing the obtained data into equations, tables and graphs.

Impact of nuclear power plants decommissioning: comparison of Germany and the Czech Republic
Myslivcová, Kateřina ; Holubcová, Jitka (advisor) ; Kučerová, Irah (referee)
The diploma thesis examines the effect of decommissioning of nuclear power plants on the energy security of two European countries - Germany and the Czech Republic. First, the author focuses on theoretical anchoring of energy security. The practical part then examines both countries from the perspective of their energy mixes and policies and infrastructure interconnection. This is the starting point for the comparison of the effects of the decommissioning of nuclear power plants. Second, the author presents three scenarios to replace nuclear energy, exploring how German and Czech energy security will change. The first scenario is the use of renewable energy only. The second option is a combination of renewable energy and coal. Finally, the third option is again a certain proportion of renewable energy along with natural gas. Last but not least, the author concludes in the presented paper that, despite the various possible combinations of how to replace nuclear energy, both countries would be worse off within the framework of energy security.

Vývoj emisí skleníkových plynů a znečišťujících látek z veřejné energetiky a výroby tepla v ČR v letech 1990–2012
Rollerová, Miluše ; Mertl, Jan
The impact of public electricity and heat production on the environment in the Czech Republic has significantly declined since 1990. Nevertheless, the public electricity and heat production in the Czech Republic has remained the category with the highest share on the total aggregated greenhouse gas emissions and also have a significant influence on the state of the environment. The positive trend of pressures on the environment from public electricity and heat production during the last 25 years was influenced by investments on the environment, by implementation of new measures aimed at decreasing the level of pollution and by dynamic technological development. On the other hand, there has been no significant decline of the consumption of brown coal for electricity and heat generation; therefore, the current efforts aimed at decreasing carbon intensity of the economy by means of increasing the share of “green” alternatives (especially renewable energy sources) in the energy mix can be seen as ineffective from environmental perspective. Moreover, the Czech Republic has a significantly negative and growing balance of international trade with electricity, which is an exception amongst European countries. In the consequence, the additional burden on the environment is caused by electricity generation.

Discussion of socio-geographic aspects of renewable energy sources in Czechia
Görcs, Jan ; Hána, David (advisor) ; Pulec, Jan (referee)
Discussion of socio-geographic aspects of renewable energy sources in Czechia Abstract Modern society is completely dependent on electricity supplies in every aspect of life and the economy. The task of every developed country is protection and ensuring sufficient energy in the required quality. Otherwise, the lack or interruption of supply may paralyze the country's life and economy. The current energy problem lies on the fact that it is based on non-renewable energy sources with limited quantity. In addition, they have a negative impact on the environment. Renewable energy sources also provide limited solutions to the situation. This bachelor's thesis therefore analyses the assumptions, possibilities and potential of the development of renewable sources in Czech electricity, in relation to the energy position, environment, electricity, society and economy. The aim of the thesis is critical evaluation of the pros and cons of the implementation of alternative energy sources in the energy mix. Key words: renewable energy sources, alternative sources of energy, energy mix, solar energy, wind energy, water energy

Comparison of Nuclear Phase-outs in Germany in 2002 and 2011
Štichová, Patricie ; Nigrin, Tomáš (advisor) ; Mlsna, Petr (referee)
The work deals with the two German nuclear power phase-out plans (ie. Atomausstieg) conducted in 2002 and 2011. The aim is to compare the nuclear policies of the red-green (governed 1998-2005) and the black-yellow coalition (governed 2009-2013) in relation to the abandonment of nuclear power as an energy source and to find differences in the aspects of policies that these governments implemented. Comparison of elected political decisions of the government is examined on the basis of several criteria like the method which have been the applied on the abandonment of nuclear energy, the speed of the phase-out, the motivation for this step and short-term impacts of governmental policies in the field of nuclear energy on the structure of electricity production in Germany. In this work it was found that despite some differences, such as (non)cooperation with energy concerns, the motivation for the nuclear power phase-out, the speed of switching off of the nuclear power plants, or the legal implications, final form of a phase-out done by the black-yellow coalition is in its basic essence very similar to the original intention. This can be explained by Angela Merkel's emphasis on pragmatic way of conducting politics that leads to a prolonged centrist position and popular support of her party CDU/CSU.

Environmental Security in the Czech Republic: An Analysis of the energy mix
Šumavský, Ondřej ; Binhack, Petr (advisor) ; Plechanovová, Běla (referee)
This thesis examines the concept of environmental security in regards to its historical development and current classification in the security studies discourse. It analyzes its relationship to the concept of energy security and explains some other relevant concepts used in this study. It then carefully chooses four determinants of environmental security which are most relevant for assessing the energy mix of the Czech Republic. The evaluation of the current energy mix is then compared to the state and composition of the country's energy mix in 2040 as outlined in the New State Energy Concept (NSEC) of 2013. Reflecting on the changes of the energy mix presented in NSEC reveals the actual impact of the future version of the energy mix on the environmental security in the Czech Republic. The thesis further identifies other important factors to consider when making strategic decisions about the composition of the energy mix and energy policy in general. To conclude, a reflection on the implications of this study both on the concept of environmental security and the Czech energy decision-making is offered.
