    Electrical energy production is a common concern for society. Conventional energy generation methods rely on chemical processes that use non-renewable resources and can produce dangers byproducts. Renewable energy resources such as Solar power and Eolic energy are becoming of increasing interest. Wind or eolic energy uses the movement of the wind through a rotor system to produce electric current. To assess the potential of eolic energy development, it is necessary to have reliable in situ wind data to understand wind site characteristics and energy potential. The study presented on this report is based on in situ wind data gathered for a period of 1 year, from a meteorological tower located in Isabela, Puerto Rico. The meteorological tower was instrumented with 6 anemometers, two installed at three elevations: 40, 48 and 60 meters, and 2 wind directional vanes installed at 38 and 58 meters in addition to temperature and barometric pressure sensors located at 2 meters from the ground level. The data retrieved from the tower were validated and analyzed to determined wind site characteristics parameters such as the wind shear coefficient (α), turbulence intensity (TI), average wind speed and wind direction. The study also describes the diurnal and nocturnal cycles and its effects on the wind site characteristics and the topography of the surrounding area. From the in situ wind data analysis conclusions and recommendations are presented about the wind energy potential.
