For decades, Saudi Arabia’s vast domestic appetite for crude oil has been a stabilizing force for its petroleum industry. Yet, in a striking twist, the kingdom’s own pivot to renewable energy may now be the factor most likely to disrupt global demand.
The numbers show just how dramatic the change could be. Since 2000, Saudi oil consumption has doubled to around 2.3 million barrels per day, outpacing every nation except China and India. Much of this demand comes not from vehicles or industry but from the power grid itself: as much as one-third of the country’s oil is burned in power plants to keep air conditioners running during blistering summers.
That practice may soon end. Under the umbrella of Vision 2030, Saudi Arabia is targeting 130 gigawatts of renewable capacity by the end of the decade—equivalent to the total solar fleet currently operating in India. If realized, the International Energy Agency estimates, it would represent the single largest decline in oil-fired power generation anywhere in the world over the next five years.
Skepticism has long surrounded Riyadh’s grand pronouncements. The country has a reputation for extravagant but slow-moving megaprojects—from the half-built Jeddah Tower to the futuristic but controversial “Line” city. Commodity trackers such as Kpler still project that only a fraction of the promised solar and wind—around 11.6 GW—will actually be online by 2030, keeping oil in the electricity mix.
Yet recent developments suggest the momentum may finally be shifting. After years of delay, Saudi renewables are now moving from blueprint to reality. Since early 2024, ACWA Power, the kingdom’s leading energy developer, has connected nearly 5 GW of solar capacity and plans to double that by the end of next year. In July, the company signed agreements to deliver an additional 15 GW by 2028, part of a broader goal of 78 GW by 2030—enough on its own to replace all the oil used for power generation in 2024.
The economics are compelling. Thanks to abundant sunlight, Saudi solar electricity costs less than half the current grid average. Compared with the complexities of drilling and refining petroleum, building large-scale solar arrays is a simpler, more predictable engineering challenge—an area where the kingdom’s track record of delivering large industrial projects may finally work in its favor.
The implications extend far beyond Riyadh’s borders. As Saudi Aramco CEO Amin Nasser recently told investors, replacing oil in the domestic grid has the same effect as expanding drilling: it frees up barrels for export. If Saudi Arabia, one of the world’s largest oil consumers, effectively removes itself from the demand side of the equation, global markets could face a fresh glut at a time when supply already outweighs consumption.
That possibility is no longer hypothetical. With ACWA and other developers now executing projects at scale, the burden of proof has shifted. Skeptics must explain why this time Saudi Arabia will fall short—because if it doesn’t, the biggest shock to the oil market won’t come from electric cars in Oslo, San Francisco, or Shenzhen. It will come from Riyadh itself.
