Objectives and competences:

The purpose of this course is to acquaint the candidates with the characteristics of renewable energy sources (RES), the technologies used to convert these sources into heat, electric power and biofuel, and with the energy policy of EU and Slovenia on the exploitation of RES.

For each renewable energy source, the students learn and master the methods for the evaluation of the potential and the technical potential of the exploitation of these sources. They understand the physical, chemical and biological processes involved in the conversion of RES. The students learn about the use of methods for the modeling of RES conversion processes.

They learn about the methods for the evaluation of efficiency of RES energy conversions, as well as learn to use the software tools for the simulation of operation and for the preparation of feasibility studies for energy systems exploiting RES.

They learn and master the methods for the assessment of environmental impact and for the economic evaluation of RES systems.

They understand the significance of RES in carbon-free societies, the significance of incorporating the RES into energy policies of European policies, and learn about the available financial incentives in different countries.

The knowledge attained qualifies the students for interdisciplinary work on the implementation of RES technologies.

Intended learning outcomes:

Knowledge and understanding

Upon the successful completion of study obligations, the students:

  • know and understands the significance of RES in the production of heat, electric power and fuels;
