The problem of comparing different sectors, companies, or projects occurs very often. This problem arises of poorly chosen metodics or requirements for results. The results of such comparisons are inconclusive and then useless. The contribution of this work is a practical guide which focuses on using of data envelopment models for evaluation of different options. In this thesis DEA models are presented on renewable energy sources. For proper understanding of the problems it is necessary to define what the data envelopment models (also known as DEA models) are. The purpose of this thesis is to inform about their creation and origins and also the description of their function. There is also an introduction into the teory of renewable energy sources. Renewable energy sources are evaluated based on their input. In this thesis is a comparison of biomass with solar, water and wind energy.

Ecological footprint (EF) is a concept to measure anthropogenic influence of individuals, regions, states and society on environment, which is expressed by units of global hectares (gha). Global hectares are calculated from the equivalent number of hectares of biologically productive area, which ensure the needs of person, cities, regions or states. The calculation includes all the anthropogenic activities using renewable natural resources. EF also examines and quantifies the area needed for carbon sequestration. EF is calculated from six land use types - cropland, grazing land, forest for timber and fuelwood, fishing grounds, built-up land and forest for carbon dioxide uptake. Plants, as participants in a number of important processes on the Earth and the base of the food pyramid, can significantly modify the final EF through the value of their net primary production (NPP). Yield factors and equivalence factors are used to transfer different areas productivity (forest, cropland, grazing land, etc.) to get land use types in global hectares. The aim of the present thesis is to make a review of the concept of ecological footprint and its calculation methodology especially the effect of variability in NPP of plants in ecosystems. The influence of ongoing global climate change can affect NPP of plants and this...

This thesis focuses on energy self-sufficiency of Visegrad countries in the Energy policy of the EU and their dependance on the main suppliers of energy sources, mainly Russian Federation, further more on the role and importance of the Visegrad Group in the energy policy of EU and their energy security.

This thesis is focused on waste made by smal distilleries and utilization of this waste for energetic use. In thesis, there are described physical and chemical properties of each type of waste snd the possibility of their recycling or utilization as a raw material. Current situation and situation in ways of waste destruction were analyzed in a case study made with several chosen small distilleries. Based on this study, distillery waste is used as a raw material for energetic in a limited way. Next chapter describes technology used for separation of waste fraction and technology for re-using its energetic potential. Separate chapter consist from case study which deals with utilization of waste in a one concrete small distillery for energetic use.

Bachelor thesis deals with the impact assessment of introduction of the requirement for processing energy performance certificate (PENB) for buildings in possession of public sector. It inspects in detail Czech as well as European legislative connected with energy efficiency, and it examines the differences in approaches to its implementation between EU member states, and its consequences. Moreover, thesis inspects the impact assessment process of EU legislation. Main part of thesis consists of an evaluation of approach of Czech public sector to fulfilling given obligations. From inspection of sample of municipalities, it shows that the targets set by legislative are not being met. At last, thesis analyzes data on public contracts which indicate that there is no such methodology which would inform the state itself about the real energy performance certification impacts on national economy.

The main content of the diploma thesis is the determination of the influence of the nuclear power plant Dukovany on the landscape character of the solved location. The thesis is divided into two parts, which the first theoretical part describes the general landscape character and its parts and the legislation with landscape protection associated. Furthermore, the issue of nuclear power plants, supplemented by data provided directly from the power plant Dukovany. The last topic of the theoretical part was the description of existing methodologies for landscape character assessment. The second practical part evaluates on the basis of the modified methodology of Mr Vorl et al. the main theme of the work, thus the extent of influence of the construction on the landscape character of the solved area. An important part of the thesis is also a quantitative research on the social perception of the power plant by local inhabitants, which was done in the form of a questionnaire. Lastly, there are practical recommendations on the protection and care of the landscape.

The first chapter of the diploma thesis describes Energy policy of the European Union, especially its development, present state and its goals. This chapter also contains information about development of the single energy market. The second part of the thesis analyses oil and natural gas import dependence of the whole European Union and its Member States as well. It shows its rate and also the structure of suppliers, moreover, it describes total production, consumption and reserves of these fosil fuels. The third chapter outlines the ways how to reduce the import dependence. The last part familiarises readers with the main initiatives of the European Union in the field of environmental protection.

Chosen agriculture farm: Dubné corporation is in South Bohemia region. Analysis of inner structure of agricultural system was calculated for ten-year period 1997 {--} 2006. Data used for analysis: acreage and yield of individual crops, consumption of mineral fertilizers, cattle stock. On the basis of this analysis, using carbon balance principle, variants of agricultural inner structure project have been worked out, aimed at bioenergy production: cereals for production of bioethanol, raps for production of oil, biogas.

Bufka, A. Impact of the Kyoto Protocol on Energy Companies in the Czech Republic. Bachelor thesis. Brno: Mendel University, 2018. The bachelor’s thesis investigates the impact of the Kyoto Protocol on energy companies in the Czech Republic. The thesis is based on previous scientific findings and researches in the investigated area and applies them on energy companies in the Czech Republic. With usage of panel regression analysis with fixed effects, whilst using the Difference in Differences method, thesis leads to conclusions in the area of Kyoto Protocol’s impact on financial indicators of investigated companies. The thesis is able to prove the possible impact of the Kyoto Protocol on investigated financial indicators. Participation on environmental management in a sense of reducing greenhouse gases emissions leads to increase in financial performance of firms.

This work will try to compare lines for forage harvesting for silage, in two farms with a focus on production focus and production method of harvesting. The main value will be calculated in performance, fuel consumption and financial costs of individual work operations. All costs will be converted to 1 tonne of mass. Samples and proven subsequent analysis of the components will be taken from the final product.
