GLOBAL REVIEW OF ENERGY POLICY LESSONS FOR RENEWABLE ENERGY TECHNOLOGIES

Governments tend globally to appreciate the advantages of renewable energy production more than conventional energy production. Therefore, supporting the expansion of production capacity of Renewable Energy Technologies (RETs) in many manners, which basically aim to reduce the disadvantages of most technologies for renewable energy production: the cost and the lack of controllability. Also essential are policies that create markets, and ensure a fair rate of return for investors. It's notoriously known wind and solar power are more mature and establish with some competitive costs, taking into consideration the public incentives. Most of the countries with a significant level of RETs in its energy matrix, such as Brazil, Germany, US, China and others have demonstrated that it is possible to create vibrant markets for RETs, and to do so very rapidly; but the results in these same countries also shows that the renewable energy policies have been unsuccessful to date, in some aspect. Most of the renewable energy policies development experienced has been driven by countries with feed-in or pricing approach schemes. In order to adequate the most efficient renewable energy policy instruments most applied by governments to RETs this paper aims to organize a framework to compare and evaluate these instruments (wind and solar power for electricity production) for a different classification as discussed in the specialized literature.
