Bearing in mind the instant innovations in renewables and the pressures to adopt ecological behaviors, companies are pushed to make changes in the energy field as well. Especially companies in the automotive sector have begun to implement sustainable production practices. The Czech Republic is not an exception, suggesting that sustainable actions have begun to be more significant at the local level as well. This article addresses the state of the art of using sustainable energy actions, concentrating on the renewable energy in the automotive supplier network within a selected region in the Czech Republic. Analyzing a broad context of renewable energy utilization at the regional level, the researched company sample shows that it is not yet a common practice. The results confirm that renewable energy sourcing needs to find its economic viability or justification in environmental legislation. Only then it can further spread along the automotive supply chain.
