Renewable Energy Sources (geothermal, hydroelectric works)

General

Course Contents

The course aims to provide students with the basic theoretical background for the course ‘ΥΔΡ010
Renewable energy sources (geothermal, hydroelectric projects)’. It includes the necessary material
for understanding: (a) the existence of geothermal energy sources as well as the calculation of the
required technical infrastructure for their utilization and (b) the preliminary design of small and large
hydroelectric projects.
Content of lectures:
• Energy. Basic principles of energy technologies. Energy mix. Renewable energy sources.
Electricity balance. Temporal variation of consumptions. Energy production distinction.
• Introduction to geothermal terminology. Heat sources inside the Earth. Types of geothermal
fields and potential uses. Advantages and disadvantages.
• Hydrothermal deterioration. Sampling of geothermal fluids. Stages of geothermal research.
• Usage of geothermal energy. High and low enthalpy geothermal energy (production of fluids
and energy, networks, impact). Technical problems in the exploitation of geothermal energy.
• Financial – Technical elements of geothermal applications. Utilization of geothermal energy
in Greece. Locating and evaluating geothermal energy sources.
• Principles and fundamentals of hydroelectric technology. Hydraulic losses. Types of turbines
and their mechanical characteristics. Hydroelectric projects (water intakes, intake pipes, generating
stations, escape pipes, spillways, gate barriers).
• Preliminary design of large hydroelectric projects (general layout, technical parameters,
environmental issues, operation, and optimization).
• Small hydroelectric projects (technology, design, water abstractions, pipelines, reservoirs,
environmental issues, hydrological planning).

Educational Goals

Upon successful completion of the course, the student will be able to:
• understand the basic principles of energy technologies and energy mix, and determine the
energy balance
• identify and estimate geothermal energy potential
• calculate hydraulic losses of hydroelectric projects
• plan the general layout and siting of hydroelectric projects
• compose technical-economic reports/studies and explain the performance of geothermal
energy exploitation systems
• evaluate the performance and functionality of small and large hydroelectric projects

General Skills

• Research, analysis and synthesis of data and information
• Adaptation to new situations
• Decision making
• Individual work
• Work in an interdisciplinary environment
• Project planning and management
• Respect for the natural environment
• Promotion of free, creative, and inductive thinking

Teaching Methods

Face to face

Use of ICT means

Learning process support (teaching and communication with
students) through PowerPoint lectures, through the online
course website, through the electronic e-learning platform
and through additional electronic communication with
students (online announcements and comments, emails,
etc.). Additional material (lecture presentations, educational
videos, useful sites, and scientific articles) posted on elearning. Teacher-student collaboration time either in
person or via teleconference.
