Skills to be acquired in this module

After successful completion of the module students should be able to:

-        critically evaluate and compare three major Renewable Energy conversion processes and technologies: photovoltaics, wind energy and one out of three of solar thermal energy, biomass energy or hydro power.

-        critically appraise various electrochemical storage processes and the respective storage techniques

-        analyse various system components and their interconnections within a complex Renewable Energy supply system.

-        evaluate the Renewable Energy supply systems’ operational size and efficiency.
-        critically evaluate non-technical impact and side effects when implementing renewable energy supply systems

Module contents
