In its World Energy Investment 2026 report, published on 28 May 2026, the International Energy Agency (IEA) estimates that global energy investment will reach USD 3.4 trillion in 2026, 5% more than in 2025. It stood at USD 2.7 trillion in 2015.
Electricity-related spending already makes up nearly 60% of the total: USD 1.6 trillion for electricity supply and infrastructure, rising to USD 2 trillion when end-use electrification is included. China leads (USD 940 billion), ahead of the United States (615) and the European Union (440). Africa totals USD 110 billion.
The IEA notes that around three-quarters of the investment anticipated in 2026 is based on decisions made well before the Middle East conflict began: as with previous shocks, many impacts will only become visible later.
