The ongoing conflict in the Middle East is reinforcing a structural transformation in global energy markets, with governments and investors increasingly prioritizing security, reliability, and geopolitical trust alongside traditional factors such as cost, pricing, and environmental performance. This is according to the latest World Energy Investment 2026 report from the International Energy Agency.
The agency warns that the disruption is reshaping how countries evaluate energy projects and partners, with long-term consequences for fuel choices, supply chains, and strategic energy independence goals.
Energy security rises to the top of investment decisions
The report highlights that the conflict—and the associated risks to key shipping routes such as the Strait of Hormuz—has triggered a reassessment of energy investment strategies across import-dependent regions, particularly in Asia and the Middle East.
Historically, these regions accounted for around 80–90% of Gulf energy exports, making them highly exposed to supply shocks. The IEA notes that this exposure is now driving a renewed focus on domestic or more diversified energy sources, including renewables, nuclear power, and in some cases coal.
Early indicators already suggest stronger momentum for renewable energy deployment in markets most affected by recent energy disruptions.
Record investment in power systems and infrastructure
Global spending on electricity systems is projected to reach $1.6 trillion in 2026, rising to $2 trillion when end-use electrification is included. Grid infrastructure investment alone is expected to approach $550 billion—an increase of nearly 20% year-on-year—while battery storage investment is set to surpass $100 billion.
IEA Executive Director Fatih Birol said the world is entering a period of unprecedented energy insecurity.
“We are in the midst of the largest energy security crisis the world has ever faced,” Birol said, adding that the shift could reshape global investment patterns in a way similar to the oil shocks of the 1970s.
Global energy investment to reach $3.4 trillion
Overall global energy investment is forecast to hit $3.4 trillion in 2026. Of this, about $2.2 trillion will flow into electricity systems, low-emissions technologies, nuclear power, and efficiency improvements, while roughly $1.2 trillion will go to fossil fuels, including oil, gas, and coal.
The report notes that nearly three-quarters of 2026 investment decisions were made before the current geopolitical escalation, meaning the full impact of the conflict will only become visible over time.
Oil declines, gas and coal shift upward
Despite elevated prices, oil investment is expected to fall for a third consecutive year, dropping below $500 billion. In contrast, natural gas investment is projected to rise to $330 billion—the highest level in a decade—driven largely by new LNG export projects in the United States and Qatar.
Renewables dominate power sector investment
Investment in renewable energy is expected to reach around $665 billion in 2026, including $365 billion for solar power. Although growth in renewables has slowed after years of rapid expansion, low-emissions technologies still account for more than 70% of global power generation investment.
Nuclear expansion and coal resurgence
Nuclear energy investment is projected to exceed $80 billion annually, supported by around 80 gigawatts of new capacity under construction across 15 countries.
Meanwhile, coal investment is set to rise to $180 billion in 2026—its highest level since 2012—with China accounting for nearly 70% of global spending.
