Florida is one of the nation's fastest growing states. Therefore demand for energy is growing significantly. Florida ranks nationally among the top 5 states in the amount of energy consumed per capita. As a result of increasingly constrained production and availability fossil fuels and environmental concerns, renewable energy sources are gaining acceptance and are expected to play a key role in sustainable growth and development in the coming future. For this project, suitability of closed landfills for use as power parks was investigated. Based on the orientation, topography, status and cover make up; two landfills were selected in south Florida (North Dade Landfill and NW 58th street landfill). Technical and economic analyses were conducted to assess the site closure and development needs, and design and operational factors to evaluate the suitability of closed landfill sites for capturing solar energy. Compatibility of the closed landfill site conditions with the structural and infrastructural needs of sustainable solar energy capture systems, optimum placement and geographic orientation of the solar capture systems and auxiliary equipment, how much power can be generated and the costs and benefits of using Florida's closed landfills as power parks were analyzed. The solar empirical model results helped to obtain the values of energy yield. At the NW 58th street landfill the solar energy generation potential is 38.33 MW/h and the delivery of energy could reach 20.64 MW/h. At the North-Dade Landfill, solar energy generation potential is 58.50 MW/h and the delivery energy could reach 31.37 MW/h. The Unit Cost of Energy for a gridded PV system on a closed landfill in an urban area would be is about $ 0.100 /kW, which is close to the average cost of energy in Florida $ 0.112 /kW. Wind load analysis on solar panels was conducted for both landfills for wind speeds of 120-150 mph. Analysis performed on North West 58th Street Landfill resulted in wind pressures of 58.02 lbs/sq ft and 44.17 lbs/sq ft and wind forces corresponding to flat and south facing sloped surfaces. At the North Dade Landfill, wind pressures were estimated as 46.40 lbs/sq ft and 38.36 lbs/sq ft for flat and south facing sloped surfaces. The suitability assessment scores were 130.4 point for the 58th street landfill and 127.4 points for the North-Dade landfill 127.4 out of 180 total points (ideal site). This study provides guideline to establish some criteria to implement PV system at Florida Florida's closed landfills to generate electricity and promote solar technology in response to growing demand for sustainable energy sources.
