Ilek

Bringing maturity without losing the brand’s charm.

Energy

Where nature, power and people connect

Reposition ilek as a leading force in green energy, without compromising what makes it different.As ilek grew from a challenger into one of France’s leading green energy providers, its brand needed to evolve with it. The company wanted to challenge the perception that renewable energy is fragile, unreliable, or restrictive, while bringing its local producers and commitment to genuinely green energy to the forefront.

We built the brand around the idea of connection. 
ilek connects people directly to the producers and natural sources behind their energy, making renewable power feel tangible, local, and human. Rather than presenting ecology as a constraint, we positioned ilek as a celebration of nature and the people working to harness its power responsibly.

A visual identity that brings the sources of energy closer to people. 
Authentic photography captures French landscapes and local producers, from solar farms and wind turbines to biogas and hydroelectric sites, putting real faces and places behind the energy we consume. Vibrant colours challenge the conventions of green energy, while modular illustrations and a contemporary, tech-driven typographic system balance the natural with the modern. The result is an identity that feels optimistic, credible, and as alive as the energy it represents.
