Recent Advances in Energy, Environment and Development Wind energy potential in Greece using a small wind turbine J. G. Fantidis, D. V. Bandekas*, N. Vordos and S. Karachalios Department of Electrical Engineering Kavala Institute of Technology St. Lucas, 65404 Greece [email protected] Abstract:-The aim of this study is to outline the wind speed distribution in Greece and examine the potential of using this resource for generation of wind power in the country. Long-term wind speed data from 69 stations are analyzed in order to calculate the energy output for a small 2.5 kW installed wind turbine at each site in Greece. The Homer software was used to predict the energy production, the cost of energy and the green house gas emissions reductions. Key-words: - Renewable energy, Homer software, Wind power, Cost Of Energy, GHG Emissions 1. Introduction calculated using Homer software. HOMER (Hybrid Optimization Model for Electric Renewables) is a modelling tool that facilitates design of electric power Energy has played a vital role in the development of systems [6-7]. The assessment criterion of the analysis human being since the industrial revolution of the 18th is the electricity production. The project takes for century. The significance of energy in economic granted a small-micro wind turbine of 2.5 kW, at each development has been recognized almost universally of the 69 locations to calculate the electricity and energy consumption is an index of prosperity and production, the Cost Of Energy (COE), the Capacity standard of living of people in a country. Basic life Factor (CF) and potential emission reduction due to requirements such as water and food are also obtained the wind turbine. and transported by the energy. Hence, supplying high quality and uninterruptible energy with the lowest costs is an essential requirement. Due to climate 2. Global trends of wind energy effects, air quality issues, rapid depletion of fossil fuel resources and increasing of fuel prices national Wind energy technology has developed very fast decision makers increasingly emphasize deployment during the last 20 years and wind is rapidly becoming of less carbon-intensive and more sustainable a practical source of energy for electric utilities electricity sources [1-2]. around the world (Figure 1). The recently data of wind The idea of using wind to produce work is not a new energy development on various continents indicate concept. Wind power was used, inter alia, by that the growth rates is high not only in the European windmills and sailing ships, for water pumping and Union and in the USA but also on developing irrigation and for grinding grain [3]. Wind energy is countries. In 2010 China installed almost half the clean, inexhaustible, environmentally friendly, and global market (16.5 GW) and is the new leader of sustainable source of energy. Technology of the wind power in the world (Table 1) [5]. According to extraction of power from wind with modern turbines the forecasts of the Global Wind Energy Council [8] is a well established industry, at present. According to wind energy will supply approximately the 16% of the Resch et al. the global theoretical potential of wind worldwide electricity demand. energy was estimated at 6000 EJ however the technical potential of wind energy is 600 EJ [4].
