Course aims:

• Starting from the knowledge of the fundamental physical phenomena, the present course deals with the conversion technologies of the renewable energies into usable forms of energy, considering the current state of the art.
• It will deepen not only the electrical sources, but also other forms of unconventional energy encountered in nature.
• The objectives of the course are related to the familiarization of the students with the types of renewable energy sources: solar, wind, geothermal, biomass, hydroelectric energy and fuel cells
• It also deals with energy capture and actual conversion solutions.
• Describing the technical specifications, installation and operation of equipment on renewable energies.
