Learning outcomes:
After successfully completing this module, students will be familiar with and have mastered sound decision-making principles for the selection and operation of decentralized energy generators.
They will understand and be able to evaluate the challenges of and associated decisions by and for the energy system transition in Germany, also in terms of international agreements.
They will have deepened their knowledge regarding the market motivation for the construction and operation of regenerative energy plants, energy distribution networks and energy storage systems, so that they can make reliable statements regarding their use from a technical, ecological and economic point of view

Teaching methods/Media:
Seminaristic lecture. Students must prepare and present at least one topic. The topics will be distributed at the beginning of the lecture and presented after an one-on-one discussion. The lecture will be complemented by lectures from experts and visits to renewable energy production plants. Practical exercises such as recording a solar cell characteristic curve independently or experiments on different heat exchangers will promote a better understanding of the various regenerative energy converters.
