Comparison and classification of ecological impacts of different types of power stations
Kunc, Dominik ; Bartošík, Tomáš (referee) ; Mastný, Petr (advisor)
The main subject of this work is to compare the ecological impacts of different types of power stations, to describe the possibilities how to reduce some of their harmful effects, and to design a cleaner electricity production process. Firstly the summary of this paper structure is introduced and the choice of its subject is explained. The second part describes the structure of energy mix in the Czech Republic in 2009 and in the following subheads there are defined basic principles of the particular power stations’ functioning, harmful effects rising during their operating and their impacts on people and the environment. There is the evalution of the power plants that created the indispensable amount of electric energy in 2009, which are: thermal power stations (mainly coal-fired ones but also the power plants burning biomass and the gas power plants), nuclear power plants, water power plants, wind power plants and solar power plants. Further there is mentioned the economical demand of energy generation from various sources and thein potential in our country in the next years. In the following part is focused on the possibility of reducing harmfulness in present electricity production, to the reduction of carbon dioxide emissions. It briefly describes the influence of this greenhouse gas on warming of our planet, what methods of capture carbon dioxide are recently available, what are the principles of these methods and what are the possibilities of carbon dioxide storage and transportation. Then we sum up economic demands of power production in the relation to useage of these technologies in various types of power plants. Likewise the possibilities of their realization in the Czech Republic are discussed. At the end of the second chapter we estimate the change of energy mix in the Czech Republic as a possible reduction of detrimental effects created by electric power production. In the third part we classify and compare these harmful impacts. Last chapter is focused on the evaluation of our energy mix estimation.
Electricity Consumption Progression Analysis
Kunc, Dominik ; Procházka, Jiří (referee) ; Bartošík, Tomáš (advisor)
The aim of this thesis is to briefly introduce the reader to the problem of development of the electricity consumption, to show the possibilities of its prediction, and provide an example of electricity consumption analysis, which may serve as a basis for long-term forecast. The first part of this work is devoted to brief overview of the development of consumption of electrical energy in the Czech Republic and factors associated with that development. The main events of Czech electrification history are outlined, as well as factors influencing the magnitude of the demand for electricity in the recent times. There are described the possibilities of the influence of foreign exchange and price of the electricity, net losses, GDP, the consumption of gas, the number of inhabitants, or the structure of the economy. This work further describes the development of the consumption of electric energy abroad and comparison of the electricity consumption in the Czech Republic to its neighboring countries, in which there are apparently influence by variety of factors that affect the consumption development trend. For more complex overview, the electricity consumption of most of European states is being noted, and near the end of the chapter the development in poorest countries and in quickly growing economies is shown. The fourth chapter mentions methods for short and middle-term prediction of consumption of electricity. There also is more consistent description of possibilities useful for long-term prediction, for which the use of the results of statistics analysis is possible. The description of observed data that are used to find the dependences of different factors is made in the following part. Further the approach of the statistics analysis used in this thesis is shown, and the key terms are explained. The dates concerning the consumption of Czech Republic are analyzed, followed by the states with similar trend of the consumption and finally other European states. Sixth chapter examines the possible uses of the outcomes of statistical analyses for long-term prediction of electricity consumption. The conclusion sums up the knowledge acquired during the research concerning problem of electricity consumption and my own analysis of data.
