Research from the E3G thinktank indicates that the ongoing global shift away from oil consumption will create significant economic and political challenges for nations with limited economic diversification. Countries such as Nigeria, Iran, Angola, and Algeria face particular vulnerability due to their heavy reliance on oil revenues for government operations and public services without sufficient capital reserves or economic alternatives.
Oil demand is already declining in many regions as renewable energy expands, with geopolitical events further accelerating the transition. Global demand is projected to reach its peak in the early 2030s before entering a period of contraction, forcing oil-producing nations to compete for a diminishing pool of buyers. The E3G analysis, developed over two years through scenario planning with more than 100 government officials and experts, projects severe revenue losses for major producers. Algeria faces an anticipated 87% revenue decline, while Nigeria could experience drops exceeding 60%.
These fiscal shortfalls will create significant challenges for state capacity and public service delivery. In Iraq and Libya, oil revenues constitute 70% to 90% of government income, while 17 countries worldwide rely on oil for more than 40% of government revenue. Several nations already struggle with debt servicing, consuming substantial portions of government budgets. The resulting gaps in basic services could destabilize social structures and potentially trigger migration, civil unrest, and regional conflicts.
Experts emphasize that delaying the energy transition poses greater risks than managing it proactively, as climate considerations require continued acceleration of the shift away from fossil fuels. However, addressing the transition’s consequences will require coordinated international action involving the International Monetary Fund, World Bank, financial institutions, and governments. Major economies must better coordinate communication regarding future demand patterns and treat adjustment assistance as part of foreign and economic security policy rather than isolated development initiatives.
China’s oil consumption has already begun declining due to electric vehicle adoption, while India’s consumption trajectory remains uncertain and could prove pivotal in determining overall global demand patterns.
