In the last decade wind power source was the fastest-growing energy source. Technological learning curves for this sector fall down by a 15% a 20% rate each 3 years. Countries which are committed with wind power are running after the target of 12% wind into the worlds electrical production by 2020. The contribution of the offshore wind power (OWP) source is fundamental on covering such target, due to the proximity to load centers, efficiency &scale savings and reduced environmental and visual impact. Although the growth of the Brazilian power generation system in 2006, there is a gap on fulfilling demand in the short run. Nevertheless, Brazil has abundance of winds suitable for power generation, as a previous industrial framework, necessary on developing this sector. Even that a governmental program has come (PROINFA), wind power sector has not risen as expected yet. The goal of this thesis is to reinforce the debate about the importance on diversifying the Brazilian power matrix, towards the strategy of energy security supply as the reduction of greenhouse gases emissions. On reaching such a goal, this thesis states arguments by a generic approach and also by a specific approach. In the generic approach, it proposes a larger share for wind into the Brazilian electrical matrix as one of the options that should be considered in a more relevant manner for the tactics of diversifying the electrical matrix, following the example given by countries with larger abundance than Brazil regarding on natural gas production, as it is the case of the United Kingdom. In the specific approach, this investigation exemplifies possibilities of contributions from the OWP for the tactics of diversifying the matrix, following the example given by a country with higher predominance than Brazil regarding on using large hydropower as the main national power source, which is the case of Norway. The method taken for reaching the thesis goal involves the following steps: (1) to clarify on some aspects regarding energy production and its respective environmental problem related to the greenhouse gases emissions;(2) to clarify some aspects about the development of wind energy systems in Brazil and in the world and also some aspects about the development of OWP projects in selected countries; (3) to explore examples of articulation between OWP systems with offshore fossil energy production systems, in order to argue about the synergy that is possible between them; (4) to analyze and debate about the Brazilian governments proposal for the electrical matrix in the long run; (5) to propose some possibilities of developing OWP systems in Brazil, starting by small-scale pilot projects. If the case the propositions of this thesis come true in the future, the earnings for this country, which a world leader in clean &renewable energy, would be the following: value creation into the offshore fossil energy production; growth of learning about the OWP technologies; the partial relief of power supply for the coastal load centers; rationalization on the use, transport and foreign dependence of natural gas resources; pushing dynamics for Clean Development Mechanisms (CDM), as for industrial markets and employment.
