Interdisziplinäres Unterrichtsprojekt „Regenerative Energien und effiziente Energienutzung
Date du début: 1 juin 2015, Date de fin: 31 mai 2016 PROJET  TERMINÉ 

In the interdisciplinary teaching project „Renewable energy and efficient use of energy“ the participating students from the dual system focused on different aspects of the topic „renewable energies“. Specifically, this meant that they dealt with different methods for the production of alternative energy and its direct, indirect and interconnected usage and storage, the production of biogas for example, the degradation of water with electrical energy from sunlight and the storage of the obtained energy through degradation of water for the production of hydrogen with the aim to operate a fuel cell. One of the main difficulties in using alternative energy is the transport and especially the storage of the electrical energy which was recovered from photovoltaic. The aim of this project was to create an interconnected system consisting of the production of electrical energy, its conversion into hydrogen, the storage of the obtained energy carrier and its use in a fuel cell for example which again transforms hydrogen into electrical energy. By determining the overall efficiency and assessing the energy budget we managed to evaluate not only a qualitative but also a quantitative perspective. A second aspect concerned the direct application of the electrical energy through photovoltaic for the power supply of a mobile phone charging station. The removal and charging of the battery was regulated by a programmed micro controller. The installing and startup operation of the necessary photovoltaic modules was done by the trainees of engineering and electrical engineering. A third aspect was the energy recovery through a chemical approach, especially through electrochemical galvanic processes and the production of biogas from organic substances. In order to apply a higher technical demand the process monitoring was carried out by programmed microcontroller guided sensors and the production of biogas happened in a small pilot plant.This pilot plant was constructed by a group of machine engineering technicians. The construction took place on the basis of a procedural specification which was done by the chemical technician trainees. The success outcome was an interdisciplinary project. All trainees from the subjects chemistry, engineering and information technology worked together in cooperation. Each of the different project groups consisted of the same number of students of Colegiul Tehnic „Costin D. Nenitescu Pitesti“ and the Berufskolleg Uerdingen. The results of the learning process were various: Planning and implementing of different aspects of renewable energies, the evaluation of the effectiveness of each energy production procedure and the comparing among them as well as process implementation under technical conditions including a realistic process monitoring in cooperation of all participating subjects. The project took place in the laboratories and workshops of the partner school „Colegiul Tehnic Costin D. Nenitescu“ in Piteşti/Romania. At the same time of the stay for students a project for the training personnel took place. Participants were vocational school teachers as well as trainers of the dual partners from the fields of chemistry, engineering, and information technology. They developed together with their Romanian colleagues an interdisciplinary teaching project "Renewable energy and energy efficiency". Due to the simultaneous presence of a German-Romanian learning group the specificity of this project was that the didactic and methodological plans could be swiftly transformed into concrete teaching actions. The participants received immediate feedback so that a timely evaluation could lead to the optimization and adjustment. The developed teaching project can be used on both partner schools or the dual partners. The joint work on an action-oriented teaching project manages to set the same standards for a particular module within different vocational training systems. The carried out teaching project is a step to adapt the curricula to international conditions. The Berufskolleg Uerdingen thus makes a specific contribution to a networked European labor market.
