Global Investment in Energy to Hit $3.4tn in 2026, Renewables Attract $665 Billion

Global energy investment will reach $3.4tn in 2026, with $2.2tn flowing into clean electricity — renewables at $665bn, grids up 20% YoY to $550bn, battery storage topping $100bn — while fossil fuel capex holds at $1.2tn and oil falls below $500bn for the third straight year. For tech leaders, the AI/data center energy demand cited by the IEA as a key driver means power procurement, PPA strategy and grid proximity are becoming infrastructure decisions with direct budget impact.
