With a take-off in the Swedish names of companies within the sector of sustainable energy market, this paper will compare the names of a multitude of European companies in the same sector and try to conclude what can be said about these names. Are they global or local? Do they share a limited set of values? Is there a difference depending on the specific sustainable energetic field, e.g. solar energy, green industry, energy storage etc., or are the names diversified and cannot be analysed as a homogenous group at all? Most of the material will be collected from the catalogue ‘Accelerating sustainable energy innovations’ (EIT InnoEnergy 2020). Hopefully, the paper will find some new thoughts on how sustainability and green energy are expressed through the names of companies and their products.
