Commercial and economic comparison of traditional and alternative fuels
Dvořáková, Monika ; Sedláček, Jiří (advisor) ; Kočan, Jakub (referee)
Negative predictions about oil stocks combined with the instability in the Middle East encourage development of alternative fuels, which would reduce dependence of the world's economies on oil. The oil and petroleum derivatives are the main dependencies for vehicular traffic, which contributes to the greenhouse gas emissions by a large part. It is therefore necessary to focus on trying to reduce the fuel consumption of cars used for personal transportation. One way to achieve this goal is, for example, to convert existing cars to run on biofuels, buying a hybrid or an electronic vehicle, or, hopefully soon, hydrogen-powered automobile. Obstacles preventing a wider deployment of such fuels and drive systems are often higher purchase and operating costs. These economic disadvantages are being gradually reduced though, and in the future we can surely expect an increase in the number of alternative vehicles on the roads.

Biofuels and food safety
Štěpničková, Zuzana ; Melichar, Jan (advisor) ; Kaprová, Kateřina (referee)
The aim is to draw attention to an inefficient allocation of resources and capital, which has resulted in rising food prices and the high number of hungry people in developing coutries, which European and U.S. subsidy policy does nt accumulate capital and invest in their production. I focused on the prices of raw materials for biofuel production in connection with legislative obligations and CO2 emissions, including the impact of indirect land use changes (ILUC) and based on searches draw conclusions from primary studies that deal with macroeconomic modeling. This thesis confirmed the hypothesis that the current agricultural policy on biofuels does not comply with the theory of comparative advantage of growing food where it is advatageous both economically and environmentally.

The use of cereals for non-food purposes
PEŠTA, Antonín
The aim of the bachelor thesis was to write a summary about the use of cereals for nonfood purposes. The thesis was written in form of bibliographic search. The thesis deals with the ways of cereals proccessing, manufacturing processes and use of products. Also, there was described national support (subsidies) of particular processing. The issue of energy and industrial use of agricultural crops is getting increasingly actuall and discussed. The problem is not only use of agricultural overproduction, but also use of plant biomass as a renewable energy ressource.

The second generation of biofuels in the real world
Skalický, Michal ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
The diploma thesis deals with the problematics of biofuels as a renewable source of energy in transportation, which has recently gotten under social spotlight. The theoretical part is focused on an explanation of basic terminology, historical development and especially reasons for the need to replace current fosil fuels with respect to an increasing volume of CO2 and shortening oil reserves. The practical part compares characteristics, use, pros and cons of the biofuels of the first and second generation and tries to estimate benefits of the biofuels of the second generation in both economic and environmental area.

Biofuels used in diesel engines
Voborníková, Tereza ; Písař, Pavel (advisor) ; Petrášek, František (referee)
Impaired environment, political instability in the countries which are the main oil producers, development of the local economies and utilization of the agricultural surplus -- these theses are the main reasons for using biofuels as the alternative. Ambiguous results in these areas and publicity of inaccurate information in media give a chance to various groups to try to enforce their own interests in that area. In this paper I discuss the recent situation of "MEŘO", the dominant bio-component adding to the oil, in the Czech Republic. I study the fuel market relations, production capacities, base of raw materials as well as the impacts of new factory in actual area. I try to find the answers to the most controversial questions. I come to the result that present first generation biofuels are the partial solution of the energetic situation, which could be good for economy and does not threaten consumers. However ecologists and economists criticize. My conclusion is that the investments on second generation biofuels and other alternative fuels development should not discontinue.

Effects of the use of biofuels in the fuel prices and food prices
Procházka, Štěpán ; Ryvolová, Ivana (advisor) ; Petrášek, František (referee)
This bachelor thesis deals with the influence of the use of biofuels in the fuel prices and food prices. The theoretical part introduces the concept of biofuels, the grounds for introducing them and try to show some increase in prices of agricultural commodities as a result of biofuel production and their impact on fuel prices. Analytical part provides a method that allows you to calculate the limit price for 1 barrel RME (rape-seed methyl ester) using the change rate of CZK / USD and change in oil prices in USD per 1 barrel. The aim of this work is to assess the impact of biofuel production on food prices and fuel.

Biofuels
Skalický, Michal ; Dvořák, Antonín (advisor) ; Fišerová, Alena (referee)
Práce pojednává o biopalivech, které představují v současnosti se rozvíjející nový trend v oblasti obnovitelných zdrojů energie šetrnějších k životnímu prostředí. Je zaměřena především na situaci v našem nejbližším okolí, tedy na Evropskou Unii a Českou republiku.

The biofuels directive and its impact on the economics
Rollerová, Alena ; Zajíček, Miroslav (advisor) ; Mach, Petr (referee)
Liquid biofuels are supposed to be an alternative way to provide energy necessary for transportation which is in modern economies dominated by oil and oil products so far. Recent policies of the EU are to support the usage of this alternative. These policies were being justified by several arguments -- decreasing of oil-import dependence, support for agriculture, decrease of CO2 emissions etc. In this paper I discuss the validity of these supportive arguments and real and mostly unintended effects of aforementioned pro-biofuel-usage policies. I conclude that none of the arguments used to support the case of pro-biofuel-usage policies is based on sound economic reasoning and none is supported by available data or can be proved on the level of scientific standard. Moreover, unintended effects are mostly harmful for economies within and outside of the EU. Hopefully, there are signs of reconsidering of aforementioned policies.
