Ennergtic heftiness of storing haylage and silage into the silage bags
JANOUŠEK, Šimon
My thesis focuses on discovering power heftiness of storing harvested material into the silage bags. The theoretical part heeds the basic needs of the procedure of preservative process during preservation of fodder plants. There is a brief characteristic of most widely used technological procedures of storing harvested material into the storage area, structure of technological units, characteristic of individual means of mechanization for harvest and subsequent storage of solid pasturage. The practical part is focused on measuring of power heftiness of storing haylage and silage into the silage bags. There is also comparison of agricultural limits of power drain to other methods of stored material into the storage area.

The effectiveness of subsidies to reduce the energy intensity of enterprises
Navrátilová, Lucia ; Potluka, Oto (advisor) ; Sobotka, Ladislav (referee)
The thesis is devoted to assessing the effectiveness of subsidies spent on improving energy efficiency in the business sector. It analyzes the use of energy resources, international development in energy consumption and legislation focused on energy efficiency. Further, it analyzes two possibilities of obtaining funds for measures improving energy efficiency, subsidies and bank loans. There are given characteristics of the subsidy program Eco-Energy from the Operational program Enterprise and Innovation 2007 - 2013. In the practical part, the effectiveness of subsidies from this program is assessed by comparison of the supported and unsupported companies.

Úspory elektrické energie ve zpracovatelském průmyslu
Pešák, Jiří
This thesis features an overview of technologies that convert various forms of energy into electrical energy, and brings a description of a transmission system. Current energy situation in the Czech Republic is evaluated and views for the year 2014 are predicted. Second part of the thesis is focused on the energy evaluation of the manufacturing enterprise model. On the basis of all the information obtained, possible measures to reduce the final electricity consumption of the factory are suggested.

Energy intensity process to save grass silage volume bags
ONDRÁČEK, Vojtěch
The aim of this work was to measure and evaluate the energy intensity of grass silage during storage in bulk bags. The values were measured on a line consisting of tractor and ma-chinery for storing forage. Further information was obtained from the service line. The results were over-straightened with technical and technological norms for agricultural production and other ways of storing silage.

Biomass processing for direct combustion
MAREK, Jakub
The aim of this work was to create an overview of the possibilities for using biomass for energy purposes, and treatment technologies for direct combustion of biomass. Furthermore, it was assessing the energy intensity of production of wood briquettes and compared the amount of energy supplied to the process, the amount of energy gained by burning the fuel. As the data were used to assess the monthly energy consumption for the years 2009 and 2010. The average value of energy supplied to the manufacturing process is 91.9 kWh per tonne of briquettes produced in 2009 and 89.8 kWh/t in 2010. The amount of energy embedded in the production of briquettes, then 15 450.7 MJ per tonne of fuel. When compared with the calorific value of briquettes, then the result of the manufacturing process has an energy recovery fuel.

Trends and contexts of development of the energy sector
Novotná, Petra ; Czesaný, Slavoj (advisor) ; Munzi, Tomáš (referee)
The world is nowadays dependent on energies, which become scarcer and scarcer. Petroleum reserves are shrinking and it is necessary to find new suitable substitutes. Energy consumption is increasing and energy crises are threatening the whole world. This caused price increased of all energies. Prices and consumption can decrease because of economic crisis, however when recession is over prices of energies are likely to grow again. Economic crisis can cause energy sources are predominantly located in politically unstable countries and other countries are dependent on them. National strategies on energy sector are therefore crucial. The Czech Republic with other countries consumes more energy than actually needed. Savings on energies are becoming more important. The production and consumption of energies have harmful by-products polluting the environment which is not desirable. Renewable resources are much less harmful to the environment but their consumption is still limited. Big potential could be also in nuclear energy and coal power plants with new technologies. The goal of this paper is to analyse individual indicators of energy sector of the Czech Republic and compare it internationally, set the strengths and weaknesses of this sector.
