A 100% green French electricity and gas supplier, Ilek is fully integrated into the energy transition and the fight against global warming. It's in his DNA and his vision.
SirEnergies explains everything to you in less than 3 minutes.
Ilek is a French green energy supplier created in 2016 and based in Toulouse. Its vision is to democratize access to renewable energy for everyone.
The company supplies individuals and small businesses with green electricity and bio gas.
The added value of Ilek is to offer its customers the opportunity to directly choose their producer of renewable energy in a short circuit (energy from wind, hydroelectric, solar and biogas in France).
In 2017, a partnership was signed between Ilek and Enerfip (a crowdfunding platform for the energy transition) for green energy producers. The company was classified as “really green” by Greenpeace at the end of 2018 (alongside 2 other energy suppliers: Enercoop and Energie d'Ici).
In 2020, the company was certified “B Corp”, once again proving its commitment to the energy transition.
As mentioned above, the green electricity offered by Ilek comes from several sources: wind turbines, solar panels and hydroelectric power plants. This electricity comes mainly from French producers spread throughout France.
The company is responsible for buying from these producers and remains completely transparent to its customers.
