Algeria is a wealthy country with natural resources, namely, nuclear, renewable, and non-renewable sources. The non-renewable energy sources are considered the lion’s share for energy production (98%). Algeria’s efforts to ensure and strengthen its energy security will take an important step in the coming decades by commissioning new energy infrastructure based on intensive use of water, coal, nuclear, non-renewable, and renewable sources. The implementation of new power infrastructure is expected to be operational from 2030. The renewable power realization in Algeria is relatively less compared to other African countries, i.e., Morocco, Egypt, South Africa, etc. The total renewable power installed capacity in Algeria reached 686 MW in 2020, as part of its national energy portfolio, although the Algerian government has spent tremendous efforts on introducing new sustainable technologies to enable the transition towards a cleaner and sustainable energy system. Indeed, the country announced its plan to install around 22 GW of renewable energy capacity by 2030. It will include 1 GW bio-power from the waste, 13.5 GW from solar PV, 2 GW from CSP, 15 MW from geothermal, 400 MW cogeneration, and, finally, 5 GW from wind. The scope of the present research provides general information about the usage of energy resources such as fossil, nuclear, and renewable sources in Algeria and also covers the energy supply outlook. The present effort is the first of its kind which discusses the application of the coal and nuclear as clean energy sources as part of renewable energy transition. Additionally, it also includes the description of the existing Algerian energy sector and information about water and water desalination and their usage in other sectors.

AbstractWind resources present a promising option to be integrated with the conventional energy sources to match the increased demand of electricity. This paper aims to investigate the possibility to set up a wind farm of 10 MW in Adrar, a region located in the south of the country. Using the wasp software, the wind resources of the zone of interest was performed, it indicates that wind speed reach 8.44 m/s at a height of 80 meters. Then, two sites Kaberten(75 north of Adrar) and Zaouia (80 Km south of Adrar) were selected. The wind farm study show that Aouia present the better performance, it can be expected to achieve from this site a production of 40 GW and a full load hours about 4044h.

Abstract Using solar energy for cooling purposes is an attractive idea with good prospects for conventional air conditioning systems. The replacement of compressor cooling systems by solar driven desiccant cooling systems could make an important contribution to environmental protection. The main argument for the applicability of solar energy is that cooling loads are approximately in phase with solar availability. The “desiccant cooling” technology is innovative in the field of refreshing atmosphere using state changes of water and operating with solar energy. The present work involves the study of an evaporative cooling system by desiccation coupled with a solar installation, reducing thereby energy consumption and using clean and free energy. The results show that the system can control moisture and therefore provide acceptable comfort conditions, confirming that it is suitable for wet areas such as coastal cities of our country.

For the study of the phenomenon of the Algerian High Plains turning into a desert, two approaches were used. The first consists of the processing of data measured on the level of weather stations located on the soil and the second by the use of a model allowing the interpolation and the extrapolation of data measured at 700 Hpa towards the soil, taking into account the terrain conditions. The two methods showed that the dominant winds are in the northern and western sectors, suggesting that the wind is not the principal factor in the progress of the sand towards north.
