This diploma thesis analyses issues related to current energy crisis and electrification process in Ghana, in connection with socio-economic impacts on society, and simultaneously presents opportunities of applying alternative off-grid solar technologies as potential solution. The main aim of the thesis is to develop comprehensive project targeted at solution for the lack of light and providing ability for charging small electronic devices, resulting to improving living conditions for inhabitants in non-electrified areas. Solution mentioned in the thesis, was developed on the basis of particular conditions considering the highest efficiency, reliability and simultaneously the lowest initial costs. Significant attention was paid to technological transfer challenge; ensuring long-term sustainability. Valuable information and experience were gained through experimental installation in the village of Akukusu, during Scholarly Internship in Ghana, leading to modification and further technology development. Particular examples of possible applications in cooperation with local subjects, which were achieved within semester study at the University of Ghana, are mentioned in closing part. These examples prove feasibility and simple modification for particular conditions. Subsequent possibilities of extension and further development are mentioned as well.

Today's globalized world is much more vulnerable than we are often willing to admit. We live in a society which is considerably dependent on a stable supply of electricity. Potential large power outage also called blackout may be a very dangerous situation for our community. Usually we don't realize all consequences there can be for our everyday life, people's health, the security and the economy of the country. Despite the efforts of the responsible authorities, the complications for the population can be very serious. The effects of such unfortunate event can be reduced in a variety of ways. An option is to support an informed society that can take care of itself in times of crisis. This text is focused on the current approach to raising and maintaining awareness of the people for masive power outage not only in the Czech Republic. The aim of the thesis is to compare the information environment of the Czech Republic with the situation in neighboring Germany. It is important to keep on mind that many important systems serving under normal conditions to inform the population will not work when such an event occurs. It can be necessary to proceed with alternative solutions and communication channels. In the education context, it's realisic to inform the majority of the population only about the most important measures and appropriate patterns of blackout behavior. With the restoration of energy supplies, the task of informing the population doesn't end. By selecting key information, this work could contribute to the society.
