I. Overview Africa is one of green power. The continent has "one of the world's best renewable energy potentials, combined with comparatively low energy consumption", by Frans Timmermans, Vice President of the European Commission 1. He aims for the continent to triple profits by expanding its renewable energy capacity. This would benefit citizens a...

This paper investigates the costs that can be avoided by using wind energy in the central coastal area of Libya. The investigation of the capacity credit was performed in a previous work. The analysis included Fuel saving, capacity saving and emission reduction (NO, SO2 and CO2) to the atmosphere. The avoided costs were translated into equivalent e...

Energy-efficient technologies provide chances for money savings and reducing environmental damages related to energy use. This paper aims to assess the energy efficiency in Libya and tools to promote its implementation. In addition, it seeks to present measures and programs that could be foreseen in the transformation sector and some end users. Dat...

Atmospheric stability conditions have a pronounced effect on velocity profiles and therefore on power density at a site and energy produced by wind turbines at these sites. So, accessing this effect is the main issue to be tackled in wind energy resource assessment and feasibility studies of any wind energy projects. In this paper wind speed observ...

The purpose of this study is to analyze the wind energy resource potential at Hun. Wind data was analyzed using diffrent statistical models and calculations were performed to forecast wind energy & power density at the site. Energy production was estimated using diffrent wind turbines which were selected according IEC standards criteria and perform...

Abstract- Based on the available data at three elevations associated with Libyan “Magroon” city, surface boundary layer wind speed profiles were obtained using power law, classic logarithmic law and corrected logarithmic law for the three atmospheric stability patterns. The daily, seasonal, and overall atmospheric stability status were estimated. W...

The residential load is one of the largest consumers of the electric energy in Libya that could be supplied by renewable energies. Renewable energy technologies and systems can be a good solution to build “Zero Energy Buildings”. A zero-energy house is proposed for Maqrun city. It is intended to use wind turbine with batteries as a storage system t...

The lowest portion of the atmosphere is vital to lives, infrastructure, and activities. It means air quality, air motion and momentum, solar and wind energy, and weather safety measures. Wind speed observations at three different heights for three Libyan coastal sites; Magron, Musrata and Darnah, were documented and analysed. Wind speed profiles we...

Life Cycle Assessment (LCA), is a technique to assess environmental impacts associated with all the stages of a product's life from-cradle-to-grave (i.e., from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling). Wind energy is one of clean energy forms during the...

The operation of wind turbines has an impact on the power quality of the electrical grid. The term power quality refers to voltage stability, frequency stability, and the absence of various forms of electrical noise (e.g., flicker and harmonic distortion) on the electrical grid. The power quality will vary from location to location, depending on th...

The Libyan energy policy makers should be aware of two aspects; the first one is the best combination of fuels that would be most beneficial for Libya. The second is the improvement of the energy system efficiency. The main objective of this study is to highlight the options of alternative energy sources and technologies suitable for Libya that cou...

This study deals with the modeling of the wake effect on the energy extracted from the wind farms. It covers the wake effect of the interaction of the upstream wind rotor with/without the upstream right and/or upstream left wind rotor. A mathematical model representing a single wake model based on the linear description of the wake is developed in...

This paper presents the results of a study that evaluated the wind potential at the central region of the Libyan coast and estimated the capacity credit of wind power in the national network. Several sites were investigated to choose the most suitable sites for wind farm establishment. Different sizes of Wind Energy Converter Systems (WECSs) were s...

تستهدف هذه الدراسة إجراء تقييم لمصدر الرياح في ليبيا، وهي تمثل المرحلة الثانية من أطلس الرياح لليبيا، حيث تم في المرحلة الأولى إعداد أطلس رياح للمناطق الساحلية والذي شمل عدد تسعة محطات أرصاد واقعة على الشريط الساحلي. ستتناول هذه الورقة خلاصة المرحلة الثانية لأطلس الرياح حيث ستشمل بقية محطات الأرصاد الموزعة على المناطق الوسطى والجنوبية. تشمل الدراسة...

n Libya the wind potential, in-land, probably is not very high. The wind speed on the coast ranges between 5.5 am/s and 7.9 am/s at 10am agl in regions of roughness class 1. The wind potential offshore is not assessed yet. Unfortunately, there are no real measurements at sea. WAsP software was used to assess the wind potential at the Mediterranean...

This paper presents a pre-feasibility study for a proposed demonstration wind farm of about 6 MW in Zwara, 125 km west of Tripoli. This study is based on previous work, which will be modified according to the latest developments in wind energy converter system sizes. It includes an economic evaluation for this project based on different assumptions...

World-wide energy consumption in the transportation sector accounts for about one quarter of the total energy consumption. This implies that thousands of tons of pollutants are emitted each year. The total pollutants include CO, CO2, HC, NOx, SO2 and soot particles. In Libya, the transportation sector counts for a big share of the total energy dema...

Wind Energy potential in the northern part of Libya (the coast) was assessed in order to develop an atlas for this region as a first step of an atlas for the whole country. Wind data for 10 years, 3-hour readings for nine meteorological stations covering the North part of Libya was evaluated.

Libya is an oil producing country, yet it is trying to develop its renewable sources of energy such as solar and wind energy. Libya has a reasonable wind potential that should be harnessed and exploited to contribute, partly, to the total electric energy demand. The Center for Solar Energy Studies is undertaking a pilot project of a small wind farm...
