Energy Security Investment Rises as IEA Sees $3.4 Trillion Global Spend

IEA

Energy security investment is accelerating as the war in the Middle East and the de facto closure of the Strait of Hormuz push governments and companies to diversify supply. The IEA expects global energy investment to reach $3.4 trillion in 2026.

Energy security investment is now shifting strongly toward electricity, grids, storage, renewables, nuclear, low-emissions fuels and efficiency. The IEA expects around $2.2 trillion to flow into these areas, compared with about $1.2 trillion for fossil fuels.

Energy security investment also carries direct metals implications. More spending on grids, storage, solar, wind, nuclear and electrification will support demand for copper, aluminium, electrical steel, lithium, nickel, rare earths and other critical materials.

The IEA described the current crisis as the largest energy security crisis the world has faced. It expects decision-makers to prioritise resilience, diversification and trusted energy partners.

Electricity Spending Becomes the Core Security Response

Electricity-related investment is becoming the dominant theme in global energy spending. The IEA expects investment in electricity supply and infrastructure to reach nearly $1.6 trillion in 2026.

That figure rises to about $2 trillion when end-use electrification is included. This shows that energy security is no longer only about oil and gas supply. It is increasingly about reliable power systems.

Power grids will be central to this shift. Grid expansion, storage deployment and electrification require large volumes of copper, aluminium and electrical equipment.

Renewables will also remain a major investment channel. The IEA expects renewables spending to reach around $665bn in 2026, including $365bn for solar, $200bn for wind and $75bn for hydropower.

Annual renewables spending growth has moderated because of lower technology costs and policy changes in China and the US. However, low-emissions sources still account for more than 70% of global power investment.

The metals signal is clear. Energy security policy is reinforcing the same material demand base already supported by decarbonisation. Grid metals, battery materials and renewable energy inputs remain structurally important.

Fuel Supply Shock Keeps Fossil Investment Alive

Fossil fuel investment is also rising in selected areas. Total fossil fuel supply investment is expected to exceed $1 trillion in 2026, returning to 2024 levels.

Oil investment is expected to fall for a third consecutive year to below $500bn. Long project lead times, supply-chain limits, offshore rig tightness and uncertainty over the duration of the price spike are limiting near-term spending outside the Middle East.

Natural gas investment is moving in the opposite direction. The IEA expects gas investment to reach $330bn, the highest level in a decade, supported by LNG export projects and demand from data centres.

Coal investment is also expected to rise to $180bn, the highest level since 2012. Around 70% of that spending is expected in China, while some Asian countries may keep existing coal-fired power plants running longer to protect energy security.

The IEA said past investments in renewables, nuclear, efficiency and electrification have already improved energy security in major fuel-importing regions. It estimated that China, the EU, Japan, South Korea, southeast Asia and India avoided around $260bn in fossil fuel imports in 2025.

The conflict is also forcing a search for new energy export routes to reduce reliance on the Strait of Hormuz. Repair costs for damaged energy infrastructure are expected to reach tens of billions of dollars.

For industrial markets, the result is a more complex energy outlook. Electricity investment is rising fast, but gas and coal remain part of short-term security planning. That mix will shape metals demand, energy costs and industrial competitiveness.

The Metalnomist Commentary

The IEA’s outlook shows that energy security and electrification are now the same investment story. The winners will be supply chains that can deliver grids, storage, renewables and critical minerals at scale while reducing exposure to fragile fuel routes.
