Energy supply for greenhouse production
Najbrtová, Zuzana ; Poláčik, Ján (referee) ; Pospíšil, Jiří (advisor)
The import of the vegetable has prevailed in the long run over the own production. In connection with this reality and increasing demand for the food with higher quality the production greenhouse is more often built. The providing heat, cold and electricity for the year-round operation is related to the construction and working of these objects. The theoretical part of this theses describes possible ways how to cover energy consumption for the model greenhouse in Kožichovice, Třebíč region. The heat losses and the year-round heat consumption were stated for the selected model and compared with the exact values from Kožichovice. The following method of energy supply was selected based on the calculated energy consumption - the separate cogeneration unit, cooperation of several cogeneration units, a biogas station, a heat pump and central heating system. These methods of energy supply were subjected to technical and economical comparison.

Energy supply of mountain cottage
Flöhsler, Tomáš ; Martinec, Jiří (referee) ; Pospíšil, Jiří (advisor)
The aim of this Graduation Thesis is to devise a system of energy supply intended to provide supply of electric and heat energy to a vacation property. The main feature of this energy supply project stands for a shift from mains power supply to alternative energy supply using renewable resources. The reason for this change is the fustiness of power lines and their negative effect on the surrounding landscape. Due to the fact that authorities did not permit renovation of these power lines, the only way to preserve the functionality of the vacation property is to secure its power supply by employing renewable resources. The vacation property (a mountain cottage) is located in Hrubý Jeseník Mountains, approximately 15 kilometers from the town of Šumperk. The thesis also contains a description of the way outlying settlements are currently supplied with energy, including the possibility of accumulation and a brief description of each electrical appliance’s power consumption. In the design itself, I calculated the necessary collector surface and analyzed the most effective collector placement. As for the wind energy system, I had to found the best spot to place the turbine. Last but not least, the thesis contains the technical-economical comparison of the proposed alternatives.

Energy supply of the ski resort
Turčina, Lukáš ; Skála, Zdeněk (referee) ; Pospíšil, Jiří (advisor)
The environmental targets of the European Union Member States are to achieve carbon neutrality in the next few years by producing green energy. To offset the impact of climate change causalities, it is crucial to increase the share of renewable energy resources as well as to reduce the dependence on fossil fuel imports. The main focus of the thesis is to increase energy sourced from alternative resources in ski resorts. Furthermore, a specific design of a wind power plant located directly in the ski resort together with the storage of the remaining energy is introduced to achieve the thesis’ objective. To select a suitable wind turbine, there is a need to choose a proper construction site that should dispose of stability and good-quality wind conditions. The performed analysis concentrates on the wind speed and frequency on the identified site. As a result, the performance of the selected wind turbine can be calculated. Moreover, given the turbine power and wind frequency, the amount of energy produced can be calculated. The potential electricity production is then compared with the ski resort’s consumption. The findings suggest that with suitable wind conditions and proper planning of energy production and storage, it is possible to cover a significant amount of the resort’s consumption. However, the model is dependent on the speed and stability of the wind, which may be highly volatile over time. Nevertheless, even such small steps can be crucial to achieving the set goals and can indicate the direction in which society will move towards.

Political and Economic Reasons for Energy Cooperation between the EU and Russia
Evgrafova, Elena ; Svoboda, Karel (advisor) ; Romancov, Michael (referee)
In this paper I investigate the energy cooperation between the EU and Russia from the political and economic points of view. The relevance of the issue is due to the growing role of energy sector, the need for security of energy supply and demand and for political and economic balance of power in the region, and closer economic integration. Two theoretical approaches, geopolitical and bureaucratic, guiding the research, explain the behavior of protagonists. To better understand the present level of cooperation I analyze the background and dynamics of EU - Russia energy trade relations. As a case study, I investigate the Nord Stream project as an example of successful cooperation of Germany as an EU member state and Russia in this field. I discuss challenges for the healthy mutual partnership in the energy sector, namely, high politicization of the issue, monopolization of Russian energy sector and low sustainability of Russian economic development, and mistrust between the protagonists. I attempt to identify possible policy changes aimed to improve this cooperation and achieve fruitful partnership, security and stability. Key words: Russia, EU, energy, cooperation, Realpolitik, international relations, oil, gas, energy dialogue, ECT, security, balance of power, geopolitics, interest groups,...
