Growing up in Saudi Arabia between the first and third decade of the 21st century, I, like most others, was aware of the slow yet noticeable changes in the Saudi climate over the years. The curse of climate change became apparent, with rain getting intense and flash floods ravaging coastal cities frequently. I was in Jeddah during the 2009 flash floods and witnessed firsthand the horrors the locals went through, with 122 dead and more than 350 never to be found again. Such a harrowing change in climate in a short span is concerning for the public as well as the policymakers who have begun to look for solutions, particularly in renewable energy.
The kingdom is part of some of the countries that are most vulnerable to climate change. Saudi Arabia has an acute water shortage issue that poses a threat to its people and the environment. Besides water scarcity, the kingdom is also a potential victim of rising sea levels (a 3mm increase per year), with about 210,000 people at risk of flooding by 2050. Temperature rises are also a concern for the Saudis, studies predict an increase between 3 to 4.2 degrees Celsius of daily surface mean temperature in the long run. According to The Climate and Atmosphere Research Center, about 600 million people in the Middle East and North Africa are at risk of heat exhaustion and heart attacks due to heat waves by the start of the next century. Extreme rainfall is also a potentially lethal impact of climate change on Saudi Arabia, as evident by the 2009 and 2018 flash floods. Precipitation in the kingdom is anticipated to increase by around 23%-41% in the long run due to climate change, which only aggravates existing issues.
Since Saudi Arabia depends on oil for its income, any factors affecting it will affect the economy and the people. Due to changes in trends, oil demand is constantly decreasing due to the increased popularity of green energy, causing oil prices to fluctuate since 2014. Studies show that the kingdom must keep about 68% of its oil reserves and 85% of its fossil fuels untouched to keep warming below 1.5 – 2 degrees Celsius. Moreover, the Middle East must abandon 40% of its oil and 60% of its natural gas reserves. Since the kingdom relies on oil for most of its income, such measures will prove detrimental to its economy and ultimately its people.
Therefore, in 2016, the kingdom announced plans for Vision 2030, which aimed to curtail many of the issues surrounding climate change using renewable energies. For this purpose, the Saudi Green Initiative was launched in 2016 and aimed to eliminate emissions by 2060. The kingdom plans to invest more than $100 billion into the project to achieve its objectives. However, there is reasonable doubt about these goals, which may sound overly ambitious. As the country continues to receive criticism from the Climate Change Performance Index which gives it an average ranking of 62nd. Therefore, there is considerable risk involved as the country is currently not on track with the Paris Agreement’s 1.5-degree Celsius limit.
During the past seven years, Saudi Arabia has invested approximately $400 billion into renewable energy, with plans to invest an additional $30 billion in the next two years. As part of Vision 2030, the government plans to achieve renewable and sustainable energy projects for 9.5 GW of RnSE (Renewable and Sustainable Energy). However, energy demand is projected to rise to 120 GW by 2032, which is much more than what is currently being worked on. The government plans to invest in solar, wind, and hydropower energy to achieve its energy demands and mitigate climate change.
Saudi Arabia has immense potential for solar power, after the government’s testing through 46 weather stations across the country. It has a large surface area and lies in the Global Sunbelt. Through solar power, the kingdom plans to generate 42.7 GW of energy. In 2019, the kingdom connected the 300 MW Sakaka power plant, 10 MW Layla al-Aflaj power plant, and 50 MW Waad al-Shamal power plant to the rest of the country. Furthermore, the Saudis have shown interest in seven additional plants in Madinah, Rafha, al-Qurayyat, al-Faisaliah, Rabigh, Jeddah, and Mahd al-Dahab with a combined capacity of 1.52 GW. In 2020, further progress was made by embarking on four more plants with a total capacity of 1,200 MW. The Saudis have made promising progress in solar energy, as evidenced by the kingdom becoming the 6th largest in solar energy generation, with plans to generate a third of their energy from solar power. However, there are large sums of costs associated with solar panels, along with dealing with external factors such as high temperatures, dust, and humidity that reduce efficiency. It can also backfire and damage the environment by causing soil erosion. On the other hand, it has been argued that the benefits outweigh the drawbacks as it is renewable and produces zero air and water pollution, which is why the Saudi government should continue to explore this option with the same momentum they currently maintain as it provides the opportunity to explore other economic policies such as carbon taxes.
The kingdom has also invested in wind energy to generate 16 GW of energy. A $500 million wind project in Daumat al-Jandal was funded by the government in 2017. ARAMCO also installed two 2.75 MW plants in Turaif and Huraymila in 2017 and 2019. Aiming to exploit its wind potential, the kingdom intends to become one the largest wind energy markets in the next half of the century. However, it requires a constant volume of wind, which is projected to decrease in the kingdom. It can damage the environment by harming the land and killing birds. However, this drawback has been explored by researchers and newer models of wind turbines are more efficient at maximizing productivity and minimizing drawbacks. Moreover, the wind farms often add to the scenic beauty which can come in handy for the kingdom that is seeking to make tourism 65% of its GDP by 2030.
The kingdom currently relies on desalination plants to curb its water shortage, producing around 4 MCM per day. It seeks to increase the number to 8.5 MCM per day by 2025 with its 28 distillation plants to achieve climate objectives. The desalination plants can also be used to produce hydropower, particularly the Ras al Khair plant, as well as others such as the ones in Jubail, Khobar, al-Khafji, Jeddah, al-Shuaibah, Yanbu, and al-Shuqaiq. However, the kingdom faces drawbacks in maximizing hydropower production due to its unfriendly landscape for dams and the lack of water bodies. Moreover, the kingdom is a tribal society at heart in its vast deserts which retains the propensity of social conflicts between the government and the locals, as had happened in the Tabuk region between the state and Huwait tribe due to the construction of NEOM and The Line. Therefore, hydropower may not be a viable option for Saudi Arabia, but it is still a viable substitute.
Renewable energy will provide unsurmountable benefits to Saudi Arabia. Studies show that the GCC region can rid itself of almost one gigaton of carbon emissions and save around $87 billion in reserves. Renewable and sustainable energy will also create many jobs for Saudis, estimated to be 80,000 by 2030. It will also preserve the rapidly depleting oil reserves of the country and reduce carbon emissions by almost 3kgs for every m3 of produced water.
There are certain challenges and risks that the Saudis currently face. There is a lack of coordination between different institutions of the state to execute policies and collect data. This causes a gap in accessible knowledge and data, clouding analysis and making it difficult to measure progress. Professionals and academics must be aware of the intensity of climate change and that is not possible without concrete data produced by trustworthy sources such as government institutions. This could also result in the misallocation of funds and resources which hinder further progress as policymakers would have a low-resolution picture of the cost of operations. Therefore, organizations like King Abdulaziz City for Science and Technology (KACST), King Abdullah University of Science and Technology (KAUST), King Abdullah Petroleum Studies and Research Center (KAPSARC), King Abdullah City for Atomic and Renewable Energy (KACARE), and others, must increase collaboration, coordination, and integration to make data more readily available both to the government and the public. Moreover, it is not possible to counter climate change solely through national programs, neighboring countries in the Middle East also need to cooperate with the Saudis to collectively deal with the issue, however, that is not always possible due to domestic issues such as civil wars, terrorism, natural disasters, and so on. These issues will jeopardize any efforts toward a sustainable future and further worsen the impact of climate change in the Middle East.
