Communities can benefit on a large-scale from the use of renewable energies (RE), which induce important local benefits due to their decentralized structure. This paper deals with the question, how to quantify the generated effects of value added and employment on a local scale. Value added is calculated as the sum of three components: tax revenues, company profits and wages, which are generated by the involved agents along the value chains of the examined RE technologies. The knowledge of local value added and employment effects can be an important factor concerning the acceptance or RE technologies as well as the further expansion of decentralized and renewable energy generation. The paper was presented at the international conference on “Micro Perspectives for Decentralized Energy Supply” (MES) in Berlin in March 2013 and published in the proceedings of the conference.
