Modal Split in Major Czech Cities: Thorough Analysis and Proposal of Policies Leading to Less Car-Dependent Urban Mobility
Bystřický, Vojtěch ; Ščasný, Milan (advisor) ; Šťastná, Lenka (referee)
This thesis focuses on examining the modal split in the five largest Czech cities. Using data from the first nationwide survey on travel behavior in the Czech Republic called Česko v pohybu, the author identifies the main factors which influence the mode choice of inhabitants of Czech cities. The data were evaluated using multinomial logistic regression. Since modal split studies of a large extent are mostly conducted in Western Europe, the United States or Asia-Pacific region, the main contribution of this thesis is to shed some light also on the travel behavior in the Central Europe, more precisely in the largest cities of the Czech Republic. The author analyzes the impact of socio-demographic variables, such as the respondents' age, education level or household income, as well as the importance of the variables related to the trip, such as trip purpose or trip distance. Further, the author also provides comparison of the travel behavior between the examined cities. Among other findings, the author finds that the entitlement to discounted public transport coupons through the ownership of a discount card does not have a significant effect on the probability of using public transport. Further, the results also show that higher education level does not lead to greater use of ecologically friendly...

Methods and technologies for carbon dioxide capture in industrial plants
Rek, David ; Máša, Vítězslav (referee) ; Sukačová, Kateřina (advisor)
The rising level of carbon dioxide in the atmosphere has negative effects on life on our planet. Humanity is now dealing with the issue through multinational organizations which attempt to motivate the current industry to develop innovative solutions to increase the energy-efficiency while lowering the amount of produced emissions. The most affected are energy-intensive sectors of the industry, such as the ceramics industry. This diploma thesis is based on a thorough research conducted on scientific literature, mainly scientific articles. The theoretical part is to familiarize one with the issue of rising levels of carbon dioxide. Next, methods to capture, store and use the gas are presented. Furthermore, the thesis focuses on one such method – microalgal bioreactors. The practical past weighs the usability of microalgal bioreactors for the purpose of carbon dioxide emissions capture in a production company LASSELSBERGER, s.r.o. belonging to the ceramic industry. Tubular bioreactor with a volume of 2000 m3 would process 3,75 % of CO2 produced by the core production machine – spray drier, during this process 367,92 tons of microalgal biomass would be produced annually.

Analysis of the renewable energy support schemes in the EU: Can be an ECOlogical also an ECOnomical?
Andoková, Senta ; Cahlík, Tomáš (advisor) ; Rečka, Lukáš (referee)
The study compares FIT (Feed-in tariff) and RPS (Renewable Portfolio Standard) as the two most commonly used support schemes for renewable energy sources (RES) in the EU. It examines a relationship of an Environmental Kuznets Curve (EKC) and by a practical experiment for public lighting in Prague the study proposes an ecological functioning of electricity grids in the EU with CO2 emissions reduction effect. The main contribution lies in the recency and originality of the econometric analysis and practical experiment. FIT and RPS analysis demonstrates that both schemes affect demand for electricity and increase its price. The econometric model was tested for 28 EU countries for 1990-2013. The results say that the EU is currently located on the downslope of the inverted U-shaped EKC with a turning point, after which the dependence begins to grow. Nevertheless, for the most of observations the turning point is too far to be a source of concern. Practical experiment has shown that installation of energy saving devices for electricity grids in the EU can bring satisfactory results in reducing CO2 emissions independently of state aid. More efficient use of existing energy sources, however, should rather serve as a complement to conventional support, phasing out with the development of RES technologies....

Does Czech Republic need a carbon tax?
Večeř, Marek ; Špecián, Petr (advisor) ; Máslo, Lukáš (referee)
This bachelor thesis deals with a concept of a carbon tax. It presents the theoretical working of the carbon tax, estimates of the tax rate, possible impacts on the economy and comparison to potential alternatives. In the empirical part of the thesis, there is, based on panel data, analyzed the effect of the size of the carbon tax rate on the amount of emissions of CO2 in selected OECD countries. Results of regression analysis indicate that every increase in the carbon tax rate by $1 per tonne of CO2 will be reflected in the decrease of emissions by 0.57 % in the given country. The thesis thus shows that carbon tax could be quite useful tool for reduction in the amount of emissions of CO2 and therefore a useful tool to reduce impacts of climate change.

Costs of Running a Car Administration Android Application
Dorazil, Jan ; Široký, Vít (referee) ; Kubíček, Radek (advisor)
The bachelor thesis deals with mobile Android platform. The application for administration of costs of running a car was created within this thesis. It describes design and implementation of the application and analyses calculation of car's consumption and carbon dioxide emissions. The application uses SQLite database, asynchronous tasks and modern user interface components.

Kostlánová, Jana ; Balíková, Jitka (referee) ; Zach, Jiří (advisor)
The aim of the thesis is focused on a research of behavior of thermal and acoustic insulating materials on natural base with major importance on fibrous insulating materials. Vital part of the thesis is aimed on monitoring of environmental aspects interrelated with retrieving of raw materials and insulating materials manufacturing. Other types of fibrous insulating materials employed in a civil engineering are presented in the text. The main objective of the thesis is an evaluation of an influence of input fibers quality to the final attributes of insulating materials. The fundamental element of material quality evaluation represents physical and mechanical attributes of examined subjects.

Comparison of the effectivity and the ecological benefits of photovoltaic power stations in different areas of the Czech Republic
SLUKA, Petr
The study is focusing on comparison of efficiency and ecological impacts of photovoltaic power stations depending on their locations in the Czech Republic. The report gives us an overview of photovoltaic power stations efficiency and also their environmental value by minimising CO2 emissions due to replacing conventional energy technologies. The research is based on data taken from energy audits of photovoltaic power stations in Vidov (South Bohemia), in Hodonice (South Moravia) and Lahošť (North Bohemia). The measured data of efficiency and CO2 savings are compared to forecast data from numerical weather prediction models PVSYST, PVGIS and Meteonorm. The project revealed, that photovoltaic power stations efficiency directly depends on their geographic location. Decisive factor was sunlight. Paired comparison showed, that there is a difference between photovoltaic power stations in Lahošť, Hodonice (P < 0,01) and Vidov (P < 0,05). The difference between real and expected datas from each photovoltaic systems was conclusive (p < 0,01). Significant was also factor of month (p < 0,001).
