Course abstract

The aim of the study course is to acquire alternative sources of energy. Properties, advantages and disadvantages, principles of renewable energy source application are analyzed, importance of renewable energy sources in Latvia, EU and from global context are discussed. Equipment, and technologies used in energy acquiring process from renewable sources are studied. Main focus is devoted to solar, wind, water and biomass energy aspects. The solar photovoltaic installations and solar collectors, wind turbines and parks, hydro-power plants are observed. Economic evaluation and business activities are covered.

Learning outcomes and their assessment

Knowledge - the types, structure and operation of solar, wind, water and biomass energy equipment and systems, the principles of management of these systems, the methods of technical and economic evaluation – grade with a mark;
Skills - assess the efficiency of the use of renewable resources and the adequacy of use, calculate energy parameters and make the choice of equipment and technologies – grade with a mark;

Competence - to make a choice of alternative energy sources for the energy supply of a specific object, to compare technologies and equipment for the efficient and economically justified use of renewable resources – grade with a mark.

Part time extramural studies:

All topics specified for full time studies are accomplished, but the number of contact hours is one half of the number specified in the calendar

Requirements for awarding credit points

During the practical work, the student prepares a small presentation about a device, within the framework of the acquired material. The grade can be obtained by writing a test, in accordance with the requirements, about the theory acquired in the course, presenting the prepared materials.

Criteria for Evaluating Learning Outcomes

Assessment of study results is based on the student’s knowledge of the acquired subject.
