Energy performance of membrane processes
Maršík, Miroslav ; Kubík, Jiří (referee) ; Hluštík, Petr (advisor)
The thesis deals with energy demands of wastewater treatment plants. The content is focused on inclusion of membrane modules to the wastewater treatment process. Two possible options of wastewater treatment are compared; first, convetional mechanical-biological wastewater treatment plants with activation and installable tank; on the other hand, plants with activation with membrane module. In the practical part, three possible options of intensification are suggested. In the first part, new mechanisms for the plant are projected, in the second part, the energy demands of this tecnological equipment are treated, and in the last point, the item bugget is processed. The comparison of investment and operating costs is made in the conclusion of the thesis.

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.

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.

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.
