MOSCOW, July 7 — The International Energy Agency’s projection that global demand for oil, natural gas, and coal will peak before 2030 has renewed attention on the concept of “peak oil,” a theory first advanced by geologist M. King Hubbert in 1956. Hubbert correctly predicted that U.S. oil production would peak around 1970.
His broader theory held that global oil production would eventually reach a maximum and then decline. According to the historical record, global conventional oil production has not yet peaked.
The IEA’s World Energy Outlook 2023 states that oil demand is expected to plateau at around 105 million barrels per day by 2030, up from approximately 100 million barrels per day in 2023. The agency attributed the projected plateau to the growth of renewable energy and electric vehicles. Electric vehicle sales reached 10 million units in 2022, according to the IEA, up from 6.6 million units in 2021.
That increase reflects a broader shift in transportation markets, though oil remains essential for transportation, petrochemicals, and plastics.
Reserves and demand
Global proven oil reserves were estimated at 1.7 trillion barrels as of 2020, according to industry data. That figure provides a substantial buffer against near-term supply constraints, even as demand growth slows. The Paris Agreement of 2015, signed by 196 parties, aims to limit global warming to well below 2 degrees Celsius.
That target would require a significant reduction in fossil fuel use, according to the agreement’s text. The IEA’s demand projections are consistent with that trajectory, though the agency has not stated that the Paris goals will be met.
Strategic context
For Russia, the timing of any peak in global oil demand carries direct implications. Moscow relies on oil and gas exports for a substantial portion of state revenue. A plateau in demand would pressure the country’s budget planning and its energy-sector investment strategy.
Analysts have noted that the shift toward renewables and electric vehicles is driven not only by environmental policy but also by energy-security considerations. Countries seeking to reduce dependence on imported oil have invested in domestic renewable capacity and electric-vehicle infrastructure.
The IEA’s projection does not specify whether the peak in demand will be followed by a sharp decline or a prolonged plateau. The agency has stated that the timing depends on government policies, technological development, and consumer behavior.
What to watch
Market participants will be watching for the IEA’s next World Energy Outlook update, expected later this year, for any revision to the 2030 demand forecast. The pace of electric-vehicle adoption and the trajectory of investment in new oil production capacity will also be key indicators. The question of whether global oil production itself will peak — as distinct from demand — remains unresolved.
Hubbert’s original theory focused on supply constraints, but the current debate has shifted toward demand-side factors. The IEA has confirmed that conventional oil production has not yet peaked, leaving open the possibility that supply could continue to meet demand for years to come.
