EKOenergy is a network of 43 environmental organisations from 33 countries. We focus on the promotion of sustainable renewable electricity. EKOenergy is also the only international ecolabel for electricity. We started in 2013 Northern Europe and are now gradually expanding to other countries, in Europe and beyond. A lot of this progress happened thanks to the active participation of volunteers, in particular EVS volunteers based at the EKOenergy Secretariat. In the project 2015-1-FI01-KA105-008597, we focused on promoting renewable energy in France and French speaking countries. It was a follow up project of earlier EVS projects focusing on France. We elaborated partnerships with a French not-for-profit organisation, as well as with a french electricity seller. We also started developing contacts with tens of stakeholders in French speaking parts of Africa and the Americas. The volunteers also did a lot for the general support of the EKOenergy Secretariat, in particular communication (translation of our texts and materials, twitter, LinkedIn...) and the coordination of the selection process for the projects which applied for financial support from EKOenergy's Climate Fund. The volunteers also actively engaged in several renewable energy campaigns (e.g. one focusing on LEED buildings and one focusing on ecohotels). Both volunteers were active members of the EKOenergy team. During their stay, there were about 10 EVS volunteers at the team, 3 employees and some trainees. They also spent a lot of their freetime together, exploring Helsinki and other parts of Finland.
