The ELISE association has strongly focused on energy efficiency, renewable energy and sustainable mobility in the Vendée department (85). Today we seek to support all audiences (public sector, private sector, individuals and young people) wishing to undertake THEIR ENERGY TRANSITION journey by leveraging all available tools on which we have developed our expertise. Consequently, our support is structured around 3 complementary areas: - Supporting changes in usage: behaviors and lifestyles, - Supporting structural investments to reduce energy consumption: energy retrofitting, mobility solutions, - Supporting the deployment of renewable energy on land and property assets.
