The EU has set constraining targets within the framework of the energy and climate plan and the French law dated August 17th, 2015 supporting green growth and aiming to increase the share of renewable energies. To insure the energy and ecological transition, the involvement of citizens is crucial and lays the grounds for more radical changes in long-term lifestyle and consumption so as to achieve the great sustainable development goals adopted by the UNO in the 2030 agenda.Each partner has its own identity (ethnicity, history, language, sensitivity) and seeks to preserve its cultural diversity. They all try to reduce their consumption of non-renewable resources, their carbon footprint, the local and global environmental risks and damages related to the development of energy systems. These major issues facing the European territory must be at the core of school education.Through a consortium and 140 pedagogical activities, e4L is created with the aim of respect for oneself, for the others, for the planet and its resources.Diversity is a key theme: it is academic, social, intellectual and linguistic. Each school is responsible for the implementation of the actions described and the dissemination of the skills acquisition procedures, the benefits and teaching files.The choice of a rewarding approach to the conventional learning capacity (formal or not) enables our education systems to innovate by integrating into our training plans the teaching methods used during the project, particularly for young people in a situation of under-achievement or exclusion. (Eurostat 2018, EACEA/Eurydice/Cedefop, 2014).The outcomes will be disseminated and accessible to all on the Internet, whatever their form: articles on the blog, school websites, media, evaluation reports, research work, educational booklets, photos. Everything will be printable in the form of worksheets.The variety of languages used (French, Greek, Slovak and Italian) to deal with a universal and sensitive issue will aim to mobilize the 8 European cross-disciplinary skills and varied scientific knowledge. Our study will examine the future-oriented fields of activity such as energy efficiency, renewable energies production, waste-to-energy schemes, recycling, eco-design, circular economy, research and investment, energy supply...Our young secondary-school pupils' interventions with primary schools or specialists are a key success factor for their future.Depending on the territories, identity anchorage and mobilisation around the issue of energy differ. The school in mainland France will harmonise the participatory exchanges. The aim is to look ahead towards a European dimension, where it is fully recognized that moving from a society of energy quantity to quality involves profound changes in our lifestyles. Through the actions, we will endeavour to achieve 3 goals: Form the citizen, Think and Communicate with foreign languages, Learn with methods and tools.E4L provides:- provision of general education on ecoefficiency-knowledge and active participation in virtual and real-life workshops-transformation of the citizen consumer behaviour-involvement of families and young Europeans.- inclusion of any type of educational establishment and consideration of suggestions.-actors' openness thanks to interdisciplinary work.-extensive, professional, and vulgarised dissemination of reusable outcomes.-informed assessment of the work done.-discussion and sharing of the methods used to deal with the themes.-emphasis on actions aiming to protect the planet and discover cultural specificities thanks to experiences abroad.-awareness on the energy transition to meet the climate challenge.Besides the 8 virtual and 6 real-life mobilities, 2 training sessions will be organized: one on a Greek island (November 2020) and one in Guadeloupe (January 2021). An information and awareness-raising congress (June 2022) will also take place. With the help of lecturers and testimonies, each country will present the energy-related challenge as the driving force of existing and future challenges (climate change, energy scarcity, water resource management, competitiveness and economic performance, employment) and also as a way of giving meaning to everyone's success.We will evaluate the degree of achievement of the scheduled activities. The aim is to show that what helps our diversity is a source of innovation, creativity, education, exchanges, while trying to implement a consumption more able to respect the planet, more resource-efficient for 2030, in accordance with the energy and climate plan and the Sustainable Development Objective n°7.
