Renewable energies carry political and financial significance in all EU countries. Their importance is translated into a major research and innovation
trend, particularly in relation to the achievement of sustainable resources
(Walz; Schleich & Ragwitz, 2011). Solar and Wind Energies offer the biggest potential for energy production, as it has been highlighted in the last decade (Sanz-Casado; García-Zorita; Serrano-López; Larsen & Ingwersen, 2012). Within he overall conglomerate of renewable energies, Germany has a bigger production than Spain, although the increase is higher for Spain in the case of Solar Energy production (2560 versus 2734 of increment), measured in tonnes of oil quivalent (during 1995-2009).
