    The core objective of this paper is to elaborate on historically implemented promotion strategies of renewable energy sources and the associated deployment within the European electricity market. Hence, at a first glance, the historic development of renewable energy sources in the electricity (RES-E) sector is addressed on Member State and on sectoral level as well as consequently discussed according to available RES-E potentials and costs. The specific focus of this paper, are promotion strategies for RES-E options as they are the key driver of an efficient and effective RES-E deployment. Therefore, the paper depicts the main types of different promotion schemes and their properties. Additionally, several cases studies of different European Member States show an in-depth analysis of the different RES-E promotion schemes. In this context, special emphasises are put on the question of effective and efficient promotion scheme designs of different RES-E technologies. Generally, conducted research led to the conclusion, that technology specific financial support measures of RES-E performed much more effective and efficient than others did. Hence, it is not all about the common question of feed-in tariffs vs. quota systems based on tradable green certificates, but more about the design criteria of implemented RES-E support schemes.

    Currently, a wide range of strategies is implemented in different countries to increase the share of electricity from renewable energy sources (RES-E). A still controversial discussion is whether quantity-driven (like Tradable Green Certificates (TGCs) based on quotas) or price-driven (like feed-in-tariffs (FIT)) instruments lead to preferable solutions for society. The core objective of this paper is to compare the perspectives of quota-based certificate trading systems for an efficient and effective increase of RES-E with FIT. The major results of this analysis are: (i) The success stories of growth in RES-E in EU member states in recent years has been triggered by FIT implemented in a technology-specific manner at modest costs for European citizens; (ii) At present, TGC systems in most countries applied show a low effectiveness with respect to RES-E deployment of less mature technologies such as solar PV (with improving tendencies in e.g. the UK or Italy with respect to certain technologies); (iii) Compared to short term trading in TGC markets the intrinsic stability of FIT systems appears to be a key element for success; (iv) Hence, currently a well-designed (dynamic) FIT system provides a certain deployment of RES-E in the shortest time and at lowest costs for society.
