We have the intention to let about 150 students and 20 teachers representing 7 vocational schools from 6 countries meet for 1 week in April 2015 in Belgium. The students will have a cultural and professional exchange in order to learn from each others'experiences. They will work in mixed (by nation, culture, sex and ethnic backgrounds) groups on sustainable energy projects, according to their professional training. Regional and national solutions to special challenges in those sectors such as energy sources can be examples of successful parctices for other regions. There is a special focus on geographical and climate conditions which reflects the complexity of the topic in each country.
