In 2001, the EU “Renewable Electricity Directive” together with the “Biofuels Directive” that was signed two years after, set quite ambitious goals for the member states by 2010. Unfortunately, the 21% of renewable electricity production was met only by very few countries (i.e. Denmark, Germany, Poland et al.), however it gave boost to many economies and the sector of renewable energies experienced significant growth with the ‘electricity production’ enjoying the biggest share [3]. In the year 2009 almost 61% of the new electricity generating capacity that was connected to the grid in the EU was from RET [4], while in 2010 the total electricity share in the EU reached 18.5%. This number, even if it is promising, is still far from the 37% that the Member States have set for 2020. Never the less, today the conditions are more favorable for higher and faster growth rates. There is a much more organized research field dedicated to the renewable technologies, better and more flexible legislation framework with number of incentives and support mechanisms and also a more open-minded industry.
