Mobile island photovoltaic system
Zelenka, Petr ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The mobile island photovoltaic system is a technology designed for electricity generation in locations without traditional electrical grid infrastructure. This compact portable device combines solar panels with batteries and other components, such as charge controllers and inverters. Its mobile nature allows deployment in remote locations (isolated houses, military bases, mountain cottages, campsites) and in emergency situations. The first part of the bachelor's thesis focuses on the issue of generating electrical energy through photovoltaic conversion and its storage in batteries, while the experimental part focuses on measuring the characteristics of photovoltaic panels with different inclinations and shading. It also models the utilization of solar energy under various sunlight conditions. The thesis provides an overall perspective on the importance of mobile island photovoltaic systems and their potential in the field of renewable energy and sustainable development.

Obama Administration's Approach Towards Fracking: Environmental Agenda As a Priority or Secondary Issue?
Povincová, Michaela ; Sehnálková, Jana (advisor) ; Pondělíček, Jiří (referee)
Hydraulic fracturing represents a significant part of the growing mining and oil industry. The most significant fracking expansion occurred during the period of Barack Obama, whose statements during his candidacy were directed against the oil industry. Based on this, environmental advocates expected Obama to seek to regulate fracking. Under the pressure, Obama was forced to take some steps against fracking, but they could not be so drastic as to create too much complication for the industry. The present work analyzes the steps and regulations adopted by the Obama administration, along with the reactions of supporters and opponents of fracking to the measures. Based on this analysis, the work points out that despite the Obama administration's efforts to introduce regulations to protect the biosphere and communities around fracking, the measures were insufficient and in some cases did not raise any standards for the oil industry. The work also found that due to the significant impact of fracking on the US economy, Barack Obama could not afford to set stricter regulations and in many cases combined the solution of environmental problems with economic solutions or with national security or energy independence. Based on this analysis, it can be concluded that the Obama administration has prioritized US...

Shale Extraction in the U.S. from the 1970s to the Turn of the Millennium: The Path to Energy Independence?
Záhradníková, Lea ; Johnson, Zdenka (advisor) ; Szobi, Pavel (referee)
Master's s thesis determines potential influence of "shale miracle" observed in the U.S. since the first decade of new millennium on energy independence which has been one of the U.S. policy priorities since the 1970s' oil shocks. Technological development and innovations supported by the government triggered an unexpected and in its way unique boom, which significantly strengthened the U.S. economy. The thesis examines impact of oil crises on the U.S. energy policy, history of unconventional gas and oil extraction, and the federal involvement in energy R&D programs. Energy independence is analyzed in terms of three fundamental pillars (reducing the amount of imported oil, reducing the energy intensity of economy and increasing energy self-sufficiency). All of the models, schemes and calculations cover a period of 1973-2013. Two indicators -- improving self-sufficiency and decreasing energy intensity of the economy -- speak in favor of achievable energy independence. However, deficient energy balance suggests otherwise. In case the need to fill the gap between energy production and consumption by foreign oil imports (which have been at their historically highest values since the 1990s) remains, then a complete energy independence as well as security is just an illusion.
