Energy efficiency in Saudi Arabia Research Paper

Energy efficiency in Saudi Arabia - Research Paper Example The paper tells that Saudi Arabian government has become adequately aware about the need to depend more on renewable forms of energy instead of fossil fuel. Though the nation is abundant in oil that ensures cheap availability of energy; the economic, environmental, and social consequences of a total reliance on fossil fuel have become obvious through various studies. Also, the Saudi Arabian terrain proved itself rich in renewable sources like solar and wind energy. The harnessing of such alternative sources poses various challenges because of their higher cost of production and fluctuating nature. Because of their fluctuating nature, it has become necessary to store them for future use. Thus, the article by Rahman et al looks into the present day energy sector in Saudi Arabia and the geographical and environmental conditions of Saudi Arabia to introduce various storage systems that are currently available. Rahman et al write the article with a complete understanding of the energy sec tor of Saudi Arabia. The article acknowledges the shortcomings of the present day energy storage systems and the need to store renewable energy in Saudi Arabia. Though there are certain advancements in the storage of energy, the growth has not been sufficient to meet the demands. Quoting Lee and Gushee, the scholars point out that if renewable energy has to become an important part of base load dispatchable power; and, it should develop the capacity for massive electricity storage. In order to assess the usability and challenges of using various storage systems in Saudi Arabia, the first factor taken into consideration is the climatic condition. It is pointed out by the scholars that batteries are highly sensitive to weather conditions such as ‘temperature, relative humidity, barometric pressure and wind speed’ (ibid). Saudi Arabia possesses a desert climate with extreme heat during the day and cold at night. Inconsistent rainfall and significant variation in temperatur e and humidity also makes the climate of the region unique. Thereafter, the scholars look into the energy supply and demand in Saudi Arabia. It is found that while Central Operating Area (COA) is considered, the maximum load during the day is 9725MW and the minimum load is 7290MW (Rahman, et al, 2012). Similarly, peak load occurs in the month of July and minimum load occurs in the month of January; and they are 9725MW and 2133MW respectively (ibid). Thus, Rahman, et al (2012) find that the average load remains below 8500MW for 16 hours in a day. So, the suggestion is that if EESS system can supply the load during peak hours, it can be charged during the off-peak hours. After acknowledging the fact that energy storage system in Saudi Arabia needs to meet all these requirements, the work looks into the major energy storage systems that seem useful in Saudi Arabia. The systems are divided into three categories based on their nature: mechanical systems, electrical systems, and chemical systems (Rahman, et al, 2012). The first mechanical system examined by the scholars is pumped hydroelectric energy storage. In this system water is pumped and stored at higher elevations. When required, this water is released onto a turbine to generate electricity. The second mechanical system is the flywheel that can generate uninterrupted DC power supply when coupled with innovative components. The third system is the compressed air energy system in which air is compressed and stored in a vessel during off-peak hours and then
