Public on Development of Electricity Consumption, and Possibility to Substitute Conventional Resources in Energy Production - July 2021
Červenka, Jan ; Ďurďovič, Martin
In the July survey the Public Opinion Research Centre focused on the issue of energetics. The survey dealt with a question of the future development of electricity consumption in the country, and whether or not it is possible to replace the production of electricity from conventional sources with alternative sources. Almost three quarters of Czechs expect to increase electricity consumption in the Czech Republic in the future. The Czech public is divided on the question of whether it is possible to replace the production of electricity from conventional sources with the production of electricity from wind energy, solar radiation or biomass combustion.

Energy and Environment in the View of Law
Pokorný, Jiří ; Damohorský, Milan (advisor) ; Smolek, Martin (referee) ; Stejskal, Vojtěch (referee)
The relationships among energetics, environment and associated climatic changes is beginning to be a subject of a complex interest of not just science but also politics and law. The reason for this is the fact that we are now at a breaking point of the development of mankind and our future steps will significantly influence its path. To obtain the energy man cannot live without, we frequently use fossil fuels, producing greenhouse gases that are warming our planet. This situation needs to change. We either find a sustainable solution or we will cause a catastrophe. The energetics must not be the cause, it has to be the solution as well. One of possible solutions for this problem is the law. It is not a stand-alone solution but it is a fundamental one nonetheless. To come up with an effective solution, a large-scale cooperation is necessary in politics, science, economics and in society as well - and there is not much time to come up with it. Keywords: energetics, environment, climate change

Šťastná, Andrea ; Pokorný, Jiří (advisor) ; Damohorský, Milan (referee)
Energy Regulatory Office Abstract Energy regulatory office (ERO) was established in 2001 by Act No. 458/2000 Coll., on business conditions and public administration in the energy sectors and on amendment to other laws as an independent specialized authority of the state administration for the regulation of energy sector and pricing authority in the field of energy. Among its main goals include prices regulation, licenses management, supervision performance over duties observance that licence - holders follow from law regulations and from ACER's resolution, European comittee's and ERO's, controls executions and in case of disharmony between desirable and real behavior of stowing remedy sancitons investigation performance of competition requirements concerning electricity or gas in markets, information providing and dissension decision - making like subject supporting alternative dissension on disputes in power - engineering branch. The aim of this thesis is to present the ERO as a whole with the approaching of its activities with a focus on defining its competence in relation to the environment, because humanity's depedence on energy brings with it negative effects that can lead to the disappearance of civilization. I tis therefore necessary to link the energy and environmental sectors and to direct the...

Energy and Environment in the View of Law
Pokorný, Jiří
Mankind has come to the point where it is fully dependent on energy. Primarily, this means the universally convertable electricity and also the thermal energy. The most widespread technologies for production of the above energies are unfortunately based on fossil fuels which, when combusted, produce greenhouse gases. Even though this is not the sole source of these substances, it belongs among the largest ones. The heightened concentration of greenhouse gases in Earth's atmosphere causes climate change which endangers the environment of the whole planet. To make this process stop or at least slow down, it is imperative to implement a wide range of measures to limit the greenhous gases production. Even though such measures will need to be carried out technically, their basis lies in law. The dissertation thesis "Energy and Environment from the Viewpoint of Law" deals with relationships between energy and environment (mostly energetics) and tools of law which can be releavant in this field. They can be found across different levels from international through European to national - Czech - level. From the perspective of applied tools, they incorporate conceptual, administrative and economical approaches. The roles of the respective means is such that the conceptual determine future progress,...

Energetic costs of tail autotomy and regeneration in reptiles
Píchová, Veronika ; Starostová, Zuzana (advisor) ; Frýdlová, Petra (referee)
Most reptile species have the ability to voluntarily cast off their tail, known as autotomy, followed by tail regeneration, which is used as an antipredatory mechanism. In spite of this being a successful ecological adaptation, the individual with its tail cast off is often influenced negatively, which includes increased probability of predation, lower locomotion capabilities, lower immunity or a change in its social standing. Last but not least, casting off the tail and the following regeneration may distinctively influence the energy of the individual, either directly through the loss of fat reserve, usually located in the tail itself, or because the regeneration of lost tissue demands a lot of energy and often requires relocation of energy at the expense of other processes. Autotomy and regeneration of the tail may thus influence important traits of physiological processes such as body growth or body mass, reproductive capabilities or metabolism intensity. The influence of autotomy on these aspects of an individual's life has been a studies topic in the last few years, but conclusions vary. The goal of this thesis is a brief summary of information about the mechanism of caudal autotomy and regeneration and also summarize contemporary knowledge about energy costs connected to autotomy and...

Environmental aspects of the cultivation of selected energy crops
KOPECKÝ, Marek
This dissertation aims primarily at determining the energy yield that can be produced, if certain species of energy crops are grown (under various regimes of fertilizing and sowing) by the Faculty of Agriculture, the University of South Bohemia, on a university's trial parcel. Zea mays L. is one of the energy crops chosen for the experiment; it is grown on a large area in the Czech Republic nowadays. Perennial crops of Phalaris arundinacea L., Elymus elongatus subsp. ponticus cv. Szarvasi-1 andMiscanthus × giganteus were also chosen for this experiment. Based on the collected data, a risk of erosion provoked by the above-mentioned crops has been determined by using USLE method. The crop stands and the soil have been analysed too. This analysis has focused on the organic matter evaluation, by using a brand new method. Last but not least, occurrence of Carabidae beetles has been studied and evaluated within the research; they are considered bio indicators of the environmental conditions. Our experiment has shown that Zea mays L. is the most high-yielding species. On the other hand, Phalaris arundinacea L. has not produced positive results; the most high-yielding variation of it only made a half yield of Zea mays L. In contrast to Zea mays L., grass species of Phalaris arundinacea L. andElymus elongatus have had an extraordinary anti-erosion capacity. Studying the amount of primary organic matter in the soil, we have found almost double amount of it in Miscanthus × giganteus andZea mays L. crop stands, compared to another two species. Monitoring oxidation reaction kinetics of the primary organic matter, we could count the oxidation speed constant of k. There have been dramatic differences between the individual soil samples. However, the data file is too complicated to draw the general conclusion from. On the other hand, evaluating the data gathered by studying Carabidae beetles and the environmental values of the crops stands, we have found out the crop stands are not too valuable from the environmental point of view. We have found out the perennial species have got an extraordinary anti-erosion capacity. We recommend Miscanthus × giganteus and Elymus elongatus, in particular, as an alternative to corn, especially to regions highly endangered by erosion.
