Course Description:
The educational objective of the course is to introduce students to wind, hydroelectric and hydrogen
cell technologies, showing their potential, advantages, disadvantages, and limitations. In particular,
the history of wind turbines, their types (horizontal, vertical axis), wind turbine parts and their
operation will be introduced. Students will learn about the calculation of the efficiency and payback
time of wind turbines. The second part of the course introduces the history of hydropower (water
wheel irrigation systems, water mills, etc.), the types of water wheels and water turbines. Students
will be given an explanation of the tidal phenomenon through some examples (estuarine tidal power
plants e.g., Severn, England). The course will also cover the principles of hydrogen cells and the
attempts of car manufacturers to replace the former petrol and diesel cars.

Competences:
− Knowledge of general and specific mathematical, natural, and social scientific principles, rules, relations, and procedures as required to pursue activities in the special field of environment protection. − Knowledge of the learning, knowledge acquisition, and data collection methods of the special fields of environment protection, their ethical limitations and problem-solving techniques. − Comprehensive knowledge of the basic features and interrelations of environmental elements and systems, as well as of the environmentally harmful substances affecting them. − Knowledge of the concepts and tools of economics and environmental economics, project, and environment management in environment protection. − Knowledge of the basics of energy management, options for energy production, their advantages, and disadvantages, as well as the concept and feasibility options of sustainable development. − Able to participate in project and proposal implementation and audit tasks based on their knowledge. − Able to participate creatively in engineering work based on their multidisciplinary skills, as well as to adapt to continuously changing circumstances. − Able to take part in environment expertise, advisory, and decision preparation work. − Efforts to improve knowledge by on-going self-education and continuously update their knowledge of the world. − Monitoring regulatory, technical, technological, and administrative changes related to the special field and enforcing them in their professional work.

Assessment: Attendance: It is compulsory to attend the lectures. The rules of education and exam directory (TVSZ) are the guidelines. Methods of qualification: Requirement of signature minimum result (40%) from written test. Exam mark from written exam test. Total points: 100. Exam marks: 85-100%: excellent (5), 70-84%: good (4), 55-69%: average (3), 40-54%: pass (2), 0- 39%: fail (1). If the student has not met the requirements of obtaining the term mark (e.g. has not written or failed the in-class test, has not submitted the measurement report, etc.), he/she must be given one opportunity to make up for the term mark in the study period. If the student is still unable to obtain the term mark through this opportunity and the requirements of the course give an opportunity for it, then the student can make an attempt to obtain the term mark on one occasion on one of the first ten work days of the examination period against a fee specified in the “Regulations of ÓU on possible benefits for students and on fees and charges payable by them” (hereinafter RBF).

Exam Types:

Written Exam
