RES Efficiency Indicators for Portugal, Spain and Germany

F. Martins and C. Felgueiras
Abstract—Nowadays one of the most important strategies in the European Union and in the World to solve energy problems is RES energy production. Many investments and financial supports are being done and implemented in many countries. However it is very relevant to have parameters and merit figures that help to evaluate the investments done and solutions implemented and that can be useful in the definition of future pathways and energy systems. In this work are calculated efficiency indicators to RES technologies for three EU’s Member States, namely Portugal, Spain and Germany that are internationally recognized to have a significant role in RES implementation and integration.

Index Terms—Energy, RES, efficiency indicators.
