During the last 15 years a renewed interest and growth in renewable energy (RE) processes emerged. It was driven by strong environmental movements, oil dependence/depletion concerns and lately national security concerns. Several RE technologies such as wind, niche photovoltaic and biodiesel are presently very competitive in certain applications versus their oil counterparts especially in Europe and certain locations in the mainland United States. Others are slowly penetrating certain markets such as fuel cells. In the discussion section an overview of the most mature RE technologies will be given focusing on their potential implementation in Puerto Rico. The discussion section will also include findings from an ongoing study at the municipality of Caguas who is becoming the sustainable model for Puerto Rico including energy. The overall analysis includes some elements of social, technical, cultural, political and economic criteria. In the latter capital, operating costs and foot print will be considered. Also sensitivity analyses will be performed regarding the energy generation potential of these processes. The technologies included are photovoltaic, wind energy, fuel cells, concentrated solar power and solar thermal water heating. These are referred to as near term implementation technologies. Other medium/long term ocean energy technologies will be discussed including tide, waves and ocean thermal. The last discussion subsection will briefly consider the area of transportation fuels (gasoline and diesel). In the last section an implementation plan will be presented for these processes including the University of Puerto Rico @ Mayagu¨ez (UPRM) capabilities and potential role in this puertorrican SAGA (Sol, Aire, Gente and Agua).
