Transcript of The Alternative Energy Options of Lafayette and Lehigh Valley

Using GIS to Evaluate the Alternative Energy Potential of the Lehigh Valley and Lafayette College By Seamas McGuire The use of GIS for Alternative Energy These systems have become important elements in
identifying ideal locations for renewable energy projects. My Goal for the Study Test GIS's ability to find ideal locations for Alternative Energy Apply this in two Scales: 1- The Lehigh Valley 2- Lafayette College Evaluate the potential of these projects. Display progression of energy development options every 5 years Evaluate how much energy could be produced by 2040. Alternative Energy Types Wind Solar Methane Hydro Analyzing Landfill Methane Locating all landfills and evaluating them by area and tons per day input. Analyzing turbines and current Bethlehem and Pen Argyl plants. Overview of Methane: Great energy potential (Pen Argyl can power 7000 households) Analyzing Wind Breaking down data from National Renewable Energy Laboratory Evaluating Turbines for low wind/ calculating power produced Overview of Wind Power: Even with low wind, power is good (1 powers 200 households) Relative price for technology is low. Has quick pay back times (approximately 2 years) Analyzing Hydro-Electric Power Locating Dams in Lehigh Valley Calculating energy potential Overview of Hydro Power Power generated is good with large rivers Payback times are intermediate (approximately 7-9 years) Power is constant/ maintenance cost low Analyzing Solar (Industrial Park) Calculating average solar output per meter in Lehigh Valley (1250 kwh/y) Finding all industrial parks Finding average industrial rooftop area Evaluating current efficiency (13.75%) with potential future (45% etc) Overview of Industrial Park Solar Lehigh Valley has abundance of large buildings Solar power is EXPENSIVE and inefficient Analyzing Solar (Small Scale) Calculating solar output per individual rooftop Find usuable rooftop area for solar power Overview of Lafayette Solar Lafayette has great potential for solar Still solar is too expensive/ payback is too long As technology improves may become realistic option Has quick payback time (often under 2 years) Analyzing Wastewater Methane Locating waste water treatment plants Evaluating turbines and plant potential (GPD) Overview of Wastewater Methane Constant and plentiful producer of energy Huge difference in payback for Large/ Small Plants Evaluating best locations by analyzing polygons Paybacks are long (approximately 40 years) Identify buildings with greatest potential Conclusion Lafayette Lafayette has several solid options, several with very quick payback time In the future, the potential for Lafayette increases. Especially for solar and hydro Lafayette CAN be completely powered by alternative energy Lehigh Valley Projects of several types can be utilized To power a significant portion of Lehigh Valley NEED SOLAR If all projects were implemented in 30 years: All projects would be paid for (except original solar!) Projects as whole would make profit.
Households powered: 117,381 Creating contour map using DEM to identify gradient and head Running raster calculation to create solar radiation layer Digitizing Lafayette Buildings for Analysis
