The students will understand the principles and potential uses for biomass as well as the shortcomings of biomass as a renewable energy. The students will develop an understanding of the growth and degradation of every type of biomass, as well as the basics of a balanced ecosystem and the sustainable use of biomass. Students gain basic understanding on biomass processing technologies. In cooperation with the Energy Systems & Society Module, one shall gain an understanding of the connection between man and the function of a healthy ecosystem and its preservation.
Competence:
The students gain competencies with critical discourse of competitive uses of biomass between human consumption, animal feed, raw material and fuel. The students are taught the issues concerning biomass transportation as well as the economic and ecological criteria involving its planning and use. They develop criteria, in order to address the complex relation between the future and a sustainable energy supply. The students gain competence to better the living conditions of rural inhabitants in developing countries through improved applications of biomass for daily energy needs.

Students gain knowledge on:
• the characteristics of components of solar thermal and photovoltaic systems e.g. solar power conversion, charge controllers, storages, miscellaneous components (pumps, cabling, ...), their individual efficiency, their dynamic behaviour, their cut-in conditions.
• the architecture and operation of different solar thermal and photovoltaic systems
• the system characteristics
• the energy balance of systems
• the sensor system for controlling and monitoring of thermal and electric solar systems.
Students gain skills on
• describing properties of solar system components
• monitoring and evaluating solar system components
• describing solar systems in their operation, their efficiency, their performance parameters
Student’s competence will be
• to compare solar thermal systems to solar electric systems in terms of energy output, type of energy output, cut in radiation and dependencies on meteorological input.
• to compare solar systems to other renewable energy systems in terms of energy output, type of energy output, cut in radiation and dependencies on meteorological input.
On the basis of theoretical knowledge students will be enabled to establish measurement procedures to analyse characteristics of grid connected and stand-alone solar PV systems as well as solar thermal systems. They are skilled to apply standard physical and mathematical formulae to evaluate solar systems. At the end of Solar Energy I and Solar Energy II they will have gained understanding in energy transfer paths and energy loss principles for radiative energy. Students will have gained the competence to analyse and critical review data from solar systems – both electrical and thermal.

Lecture Goal and Competencies:
The lecture Hydro Power I seeks to familiarize students with technological, socioeconomic and ecological aspects. Students get acquainted with basics of the technical components of Hydro Power (HP) and Ocean Power (OP) systems: their setup, their operation, their specific challenges and their linkages with one another.
At the end of this unit students may size a HP for given local geographic and hydrological conditions on a basic level. They can describe the entire setup as well as individual components. They are aware of basic challenges beyond the technical problems of HP and OP systems. Students are in the position to list advantages and disadvantages of HP and OP in comparison with other renewable energy technology.
Detailed Content*:
• 2h Theoretical background – general hydraulic terms, Bernoulli Equation, Major Empirical Formulae and their backgrounds.
• 2h Water Resource – catchment area, seasonal precipitation, flow duration curve, dam, & run off river.
• 2h Powerhouse – penstock, water hammer, cavitation, tailrace.
• 4h Turbines – main types of turbines, their characteristics & their components.
