Alternative Energy Sources with Focus on "Solar Energy Sources in Present Practice"

The thesis deals with the problems of alternative energy sources with focus on solar energy sources in present practice. The thesis introduction explains the reasons of the changes in the global fuel-energy balance and their adverse effects, characterizes individual alternative energy sources and their practical applicability. The main focus is on exploitation of solar energy. After explaining the principle of thermonuclear reactions as the source of energy in the Sun, the thesis analyses the question of production of photovoltaic cells and a solar module. It describes the types of commonly used accumulators, charges and voltage transformers. It points out all factors, which must be taken into account when handling solar panels in practice. In the last chapter, it in particular deals with the didactic instructions for teaching the topic of alternative energy sources at elementary schools, as well as the need for introduction of the mentioned topic to teacher colleges
