La confrontation avec l’urgence climatique et avec le projet de la société zero carbone demande un traitement multiple, à la fois hautement technologique et très attentif aux leçons que la nature aurait à offrir. Cette intervention mettra l’accent sur la compréhension précise et imaginative des astuces, outils et méthodes que l’observation systématique des systèmes biologiques pourra nous dévoiler.

The first civilizations have been developed in geographical areas where they found the resources they needed. Little by little, our cities became disconnected from their substrata. Transportation networks (for goods, liquids or energy) have made it possible to continue to develop the agglomerations by transporting the necessary resources. Today, at the energy level, Geneva depends essentially on fossil resources, which often come from outside the canton. The cantonal energy strategy aims to reduce our consumption of fossil fuels and increase the canton's level of energy independence. Geothermal energy plays an important role in this energy strategy and in order to clarify this potential and allow its development, the canton and SIG have launched the GEothermies program (www.geothermies.ch). This program permits to improve the knowledge of the Geneva subsoil and the resources it contains for a sustainable future. Formatted in a resource management plan, these data allow the subsoil and the resources it contains to be included in a coordinated land use planning dynamic, for the benefit of the ecological transition. Taking this information into account beforehand in prospective approaches offers new avenues not only in terms of energy but also on issues as essential as access to drinking water, irrigation, storage, geo-materials and their mutualized and coordinated management.
