Barclays sees a $3.6 trillion annual investment opportunity in this sector

Barclays analysts assert the global energy sector could necessitate approximately $3.6 trillion in annual investment by 2027, driven by AI, electrification, and energy-security considerations. The industry encompasses oil and gas, LNG, pipelines, power generation, grids, renewables, storage, and electrification. Spending is projected to expand by more than 5% annually, reaching triple the capital needed for planned AI infrastructure.

The global economy is transitioning into an era of energy addition, where demand for conventional and low-carbon energy escalates concurrently. Global energy consumption is expected to surge at a 1.9% compound annual rate from 2025 to 2050. Data centers alone may contribute around 32 quadrillion BTUs of energy demand by 2040, equating to over 600 gigawatts of capacity, roughly matching Russia's 2025 energy consumption.

AI is exerting increasing pressure on power systems, with global data center electricity usage projected to rise to 565 terawatt-hours in 2026, a 26% increase from 2025, and potentially hitting 290 GW by 2030. Underinvestment in oil and gas has created bottlenecks, with the upstream sector's capital expenditure remaining 45% below its peak.

Over 2,500 GW of renewable, storage, and large-load projects await grid connections globally. Utilities and clean technology present significant investment opportunities. Companies with robust balance sheets, strategic assets, and access to capital are deemed particularly favorable. Among Barclays' favored energy stocks, 2028 earnings estimates average 11% above consensus, with price targets suggesting roughly 30% upside potential.

In Europe and the U.S., oil services show some of the most substantial earnings upgrade opportunities.
