Skills to be acquired in this module

After the completion of the module students should be able to

-       critically evaluate and compare two Renewable Energy conversion processes which allow
         continuous power supply on demand (hydropower and biomass energy)

-       confront those systems to a Renewable Energy conversion process with intermittent output
        (marine power)

-       discuss extreme situations in Renewable Energy systems’ source and transfer such situations
        to other Renewable Energy systems

-       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

-      understand the basic chemical background of bioenergy-related materials, systems and
