This aim of this work is to analyze, assess and compare the wind power promotion strategies implemented in Germany and Brazil, both qualitatively and quantitatively. This was achieved by calculating the effectiveness and efficiency of each promotion strategy, by means of indicators of effectiveness and efficiency defined in the literature. It can be stated that Germany has implemented more effective and efficient wind power promotion strategies than Brazil. In order to verify if effectiveness has been triggered by high profits for wind power investors in each of the countries, annuities of hypothetical projects were calculated and plotted against effectiveness. While this could be deducted for Brazil, Germany?s promotion strategies make clear that high effectiveness can be achieved with low investors? profits, minimizing ?windfall? or unnecessarily high profits. Considering that wind power promotion strategies are decided and enforced by the governments and funded by the electricity consumers, this aspect is of key importance. One of the plausible reasons of the differences in the effectiveness and efficiency of the promotion strategies between these two countries can be is that Germany has collected more experience than Brazil. Yet naturally, the qualitative differences of the promotion strategies applied in each country lead intrinsically to different results. Feed-in tariffs demonstrate once again their superiority, in achieving renewable electricity generation at relatively low costs to society.
