Technical, economic, and environmental analysis for the installation of a 3MW wind power plant in Libya Abdulhamid Y albas Dept. of mechanical Engineering, Higher Institute of Science and Technology, Cyrene, Libya. ---------------------------------------------------------------------***--------------------------------------------------------------------1.1Energy policy of Libya Abstract - The motivation for the work discussed herein stems from the increasing demand for renewable energy and the declining supply of nonrenewable energy. A growing proportion of global energy production is transitioning to renewable sources. Wind energy is experiencing heightened implementation for power generation owing to its economic advantages. Libya possesses a wealth of renewable energy resources, with an average wind speed of 4.5 m/s at 10 meters and 8 m/s at 50 meters. The economic study of this plant indicates that the wind farm incurs an investment cost of $3,450,000, yielding annual savings of $499,826.70. The payback period was determined to be 7 years, the savings-toinvestment ratio was computed at 3.62, the net present value was positive, and the return on investment was 14.4%.
Libya's energy sector depends more on imported fossil fuel. Increase electricity per capita consumption by an average of 2.7, 5, and 4.7 MWh between 2002 and 2018[2]. Unpredicted costs of this fuel, coupled with an increase in global warming associated with thermal plants, pose a great danger in the energy sector. To complement this, renewable energy sources need to be harnessed for electricity generation.
2.WIND TURBINE PARAMETERS Quantifying several key features of the wind is necessary to effectively map its resource. Primarily, and most significantly, the velocity,
Key Words: wind plant, economic analysis, turbine, greenhouse gases, renewable energy.
We must precisely measure the wind over a minimum duration of one full year. Secondly, we must analyze the origin of the wind's direction. Finally, the variation in wind speed as a function of altitude must be examined to understand how wind speed measurements will be adjusted when interpolated with the wind turbine hub height [4].
1.INTRODUCTION Energy needs have significantly expanded as a result of the world economy's rapid development, particularly in emerging nations. Interest in using renewable energy has grown as a result of the understanding that the resources needed to generate energy from fossil fuels are becoming finite and that carbon emissions into the atmosphere are linked to climate change [1]. The development of a pollutionfree, renewable wind system is essential. North Africa is home to Libya, which shares borders with Algeria, West Tunisia, South Africa, South Sudan, East Egypt, the Mediterranean, and southern Chad and Niger. The population grew by 1.3% annually in 2019 after reaching roughly 637500 in 2018[2]. Libya is the fourth largest country in Africa with an area of 1.75 million square kilometers, and it ranks 17th as the largest country in the world, and most of its lands are shrubs, desert, and semidesert [3]. Generally speaking, the average wind speed in Libya is between 5 and 10 meters per second. In Libya, one of the primary benefits of wind energy is that it can meet the demand for electricity in most areas. Therefore, it is essential to create a new and remarkably amazing technical innovation industry in order to reduce global warming and the pollutants linked to energy use. But wind technology is becoming more and more attractive. There are hourly, daily, and yearly variations in wind energy output. Therefore, direct powering loads that need a consistent and continuous input energy supply is not a good fit for wind turbines.

Wind energy is the second best alternative renewable energy source. The wind speed in some coastal cities is shown in Fig -1. The average wind speed at three different heights in different cities in Libya is shown in Chart -1.
