Possibilities of geographical research in the usage of liquid biofuels in transport
Valeš, Jiří ; Netrdová, Pavlína (advisor) ; Šatra, Jan (referee)
At first there is briefly shown the history of usage and present usage of liquid biofuels in transport. The paper describes its regional differenciation in EU and with the help of basic statistical methods researches the development of differences of the meaning of biofuels in Member States. For these purposes there is created a database of shares of biofuels in energy consumption in transport. If we understand the shares of biofuels showing the intensity or the meaning of biofuels usage, we can exemine its differences. With the help of Lorenz curve there is described the development of rate of inequality of biofuels production. There is also evaluated the meaning of biofuels production in Member States by relativising it to the area of arable land. Key words: liquid biofuels, statistical analysis, spatial analysis

Liquid Biofuels in EU: Development of the Usage and Possible Relations
Valeš, Jiří ; Netrdová, Pavlína (advisor) ; Šatra, Jan (referee)
The thesis describes history, context and present situation of liquid biofuels usage in transport in the EU and with the help of basic statistical indicators researches the development of differences of the importance of biofuels in Member States. For these purposes a database of shares of biofuels in energy consumption in transport is created. If we understand the shares of biofuels as indicators of the intensity or the significance of biofuels usage, we can exemine its differences. With the help of Lorenz curve the development of rate of biofuels production inequality is described. Thesis is looking for possible relations to differencies in intensity of biofuels usage in Member states. With the main contribution of literature, there are several characteristics chosen and there are examined their relations to shares of biofuels with the help of Spearman correlation coeficient. In the closure of the thesis their possible influence on biofuels usage is discoussed. Key words: liquid biofuels, useage, share of biofuels, correlation

Energy from Agricultural Land
Šatra, Jan ; Bičík, Ivan (advisor) ; Musil, Ladislav (referee)
Thesis is concerned with relation of usable energy and space as it's widely spread source. For this purpose are introduced not only a few indicators suitable to energy management description, but also principles of environmental assessment thinking are expained, as these help to distinguish the really sustainable ways of deriving energy from space. As examples of energy-from-space extraction are introduced photovoltaics, liquid biofuels and fast growing energy plants. After a brief entry to heat supply problematics, focus is remains on a simple case study: quantifying relationship between local heat demand and local potential production of solid biomass from short rotation coppice. This so far rather hypothetic relation is examined at the municipal level, while Central and South Bohemia regions are the target area. Soil characteristics and population census data (2001) about residental habitats are used.
