MEETING THE MAJOR CHALLENGES OF OUR TIME

The climate

Climate change is a reality.
We have an opportunity to build a new economic model around renewable energies and self-consumption.

A global challenge

The climate is everyone’s responsibility.
Energy must be accessible to all.
This responsibility and accessibility must be local commitments to secure and provide territories, individuals and businesses with virtuous energy.
We need to store renewable energies cleanly and sustainably, while responding to our uses with a new approach: producing locally for local use, serving and supporting globally.
