“…Una aplicación rápida para alcanzar la zonificación de este recurso se puede conseguir integrando los SIG y percepción remota (Beccali et al 2009). Dan constancia de ello, múltiples trabajos efectuados tanto en Europa, África, Asia y en menor grado en Sudamérica, en donde se han identificado a nivel de prospección zonas de aprovechamiento energético, así como superficies y sitios óptimos para la generación de electricidad a base de biomasa forestal residual (Byrne et al 2007, MacFarlane 2008.…”

SUMMARYLand planning comprises a stage of land management whose aim is to generate proposals from analyzing the information of the territory, which represents multiple variables of the geographic space. Some of the most recent lines of planning are renewable energies and particularly residual forest biomass since this is a non used environmental element but with a high growth potential. For this task, using technological tools like geographic information systems or remote sensing permits to handle these topics and express them in a spatial zoning for decision making. According to this, a prospective work was made in the watershed of Ranco Lake, where optimum spaces were defined to obtain residual forest biomass in four vegetational units (coigüe-raulí-tepa, roble-raulí-coigüe, evergreen and forest plantations). The results showed that there exists an overall potential surface to handle of 45,555 hectares, from which the forest type coigüe-raulí-tepa highlights with a 62.4 % of the surface. Under the assumption of availability of residual forest biomass in the watershed and a scene of energetic crisis, the importance of prioritizing regional policies and research concerning the development of non conventional renewable energies is recognized.Key words: territorial zoning, GIS and remote sensing, residual forest biomass, NCRE. RESUMENLa planificación territorial constituye una etapa del ordenamiento del territorio que tiene por objeto generar propuestas a partir del análisis de información obtenida de múltiples variables del espacio geográfico. Algunas de las líneas más recientes de planificación la constituyen las energías renovables, y entre éstas la biomasa residual forestal, puesto que constituye un pasivo ambiental no utilizado pero con gran potencial de crecimiento. En esta tarea, el uso de herramientas tecnológicas como el sistema de información geográfica y la percepción remota permiten manejar información territorial asociada a la biomasa residual forestal y expresarla en una zonificación espacial para la toma de decisiones. En este marco, se efectuó un trabajo prospectivo en la cuenca del lago Ranco donde se determinaron los espacios potenciales de extracción de biomasa residual forestal en cuatro unidades de vegetación (coigüe-raulí-tepa, roble-raulí-coigüe, siempreverde y plantaciones forestales) bajo las actuales condiciones de cosecha. Los resultados mostraron que existe una superficie potencial total a manejar de 45.555 ha, de éstas el tipo forestal coigüe-raulí-tepa, con 62,4 % de la superficie, representó la mayor proporción. Bajo el supuesto de la actual disponibilidad de biomasa residual forestal en la cuenca y un escenario de crisis energético, se reconoce la importancia de priorizar las políticas regionales y la investigación en torno al desarrollo del sector de las energías renovables no convencionales.Palabras clave: zonificación territorial, SIG y percepción remota, biomasa residual forestal, energías renovables no convencionales.

“…When considering the overall feasibility of small wind turbines across the province, although not assessed within this study, there are also many political and socio-economic influences that can limit/aid the implementation of wind power in more rural communities [32,33]. However, many developing nations have shown the success of wind energy in more remote communities [34][35][36] that lack access to the national grid, owing to a multitude of factors. Small wind turbines not only provide a more reliable power source and free communities from frequent power outages, they also provide a community-oriented approach in the management and procurement of clean energy.…”

Feasibility of Small Wind Turbines in Ontario: Integrating Power Curves with Wind Trends

Micro-scale/small wind turbines, unlike larger utility-scale turbines, produce electricity at a rate of 300 W to 10 kW at their rated wind speed and are typically below 30 m in hub-height. These wind turbines have much more flexibility in their costs, maintenance and siting, owing to their size, and can provided wind energy in areas much less suited for direct supply to the grid system. In the future under climate change, the energy landscape will likely shift from the present centralized electricity generation and delivery system to a more distributed and locally-generated electricity and delivery system. In the new system configuration, the role of relatively small sustainable electricity generators like small wind turbines will likely become more prominent. However, the small wind industry has been substantially slow to progress in Ontario, Canada, and there is much debate over its viability in a growing energy dependent economy. This study seeks to demonstrate the performance of a small wind turbine, and speculate on its potential power output and trend over Ontario historically over the last 33 years using the North American Regional Reanalysis (NARR) data. We assessed the efficiency of a Bergey Excel 1 kW wind turbine at the pre-established Kortright Centre for Conservation test site, located north of Toronto. Using a novel approach, the Bergey optimized power curve was incorporated with reanalysis data to establish power output across Ontario at three-hour resolution. Small turbine-based wind power around the Great Lakes and eastern James Bay increased during winter and fall, contributing up to 10% of the annual electricity demand in some regions in Ontario. We purport that increases in power output are driven by long-term reductions in sea and lake ice concentrations affecting atmospheric stability in surrounding regions.

This research is aimed at designing, implementing, and testing a geospatial database for wind and solar energy applications in the Kingdom of Bahrain. All decision making needed to determine economic feasibility and establish site location for wind turbines or solar panels depends primarily on geospatial feature theme information and non-spatial (attribute) data for wind, solar, rainfall, temperature and weather characteristics of a particular region. Spatial data includes, but is not limited to, digital elevation, slopes, land use, zonings, parks, population density, road utility maps, and other related information. Digital elevations for over 450,000 spot at 50 m spatial horizontal resolution plus field surveying and GPS (at selected locations) was obtained from the Surveying and Land Registration Bureau (SLRB). Road, utilities, and population density are obtained from the Central Information Organization (CIO). Land use zoning, recreational parks, and other data are obtained from the Ministry of Municipalities and Agricultural Affairs. Wind, solar, humidity, rainfall, and temperature data are obtained from the Ministry of Transportation, Civil Aviation Section. LandSat Satellite and others images are obtained from NASA and online sources respectively. The collected geospatial data was georeferenced to Ain el-Abd UTM Zone 39 North. 3D Digital Elevation Model (DEM)-50 m spatial resolutions was created using SLRB spot elevations. Slope and aspect maps were generate based on the DEM. Supervised image classification to identify open spaces was performed utilizing satellite images. Other geospatial data was converted to raster format with the same cell resolution. Non-spatial data are entered as an attribute to spatial features. To eliminate ambiguous solution, multi-criteria GIS model is developed based on, vector (discrete point, line, and polygon representations) as well as raster model (continuous representation). The model was tested at the Al-Areen proposed project, a relatively small area (15 km 2 ). Optimum site spatial location for the location of wind turbines and solar panels was determined and initial results indicates that the combination of wind and solar energy would be sufficient for the project to meet the energy demand at the present per capita consummation rate..
