Example :

Circular logo, i.e. reassuring but moving clockwise, i.e. to the left i.e. at least in western countries towards the future. The 5 brushes/touches of orange might represent flames, ie. traditional sources of energy but can also hint at a wind turbine therefore evoking renewable energies. If you have a closer look you might also see a man with a cap, presumably an EDF technician/engineer with his right thumb up indicating success or "problem solved!"The blue colour seems to stand for gas or the colour of a link on the internet which would explain why the "e" is the only letter in lowercase whereas the other ones are in uppercase. This would reinforce the global impression of modernity and a forward-looking approach.
