Global clean energy investment surpassed $2 trillion in 2025 for the first time, outpacing fossil fuel investment by 2:1. This analysis examines the key investment trends, policy drivers, and market outlook shaping the energy transition in 2026 and beyond.

Investment Highlights

1. Solar Dominance

• Solar PV investment reached $450B in 2025, 380GW installed (new annual record)
• Module prices stabilized at $0.10-0.12/W after 2024 oversupply correction
• Utility-scale solar LCOE: $0.02-0.04/kWh in optimal locations — cheapest electricity source ever

2. Battery Storage Boom

• Grid-scale storage deployment: 120GWh in 2025 (3× versus 2023)
• LFP cell prices reached $55/kWh, system-level LCOS approaching $0.05/kWh for 4-hour
• Solar-plus-storage becoming default configuration for new utility PV projects

3. Offshore Wind Acceleration

• 30GW of offshore wind under construction globally across 15 countries
• Floating offshore wind moving from pilot to commercial scale (>100MW projects)
• Turbine sizes reaching 16-18MW for fixed-bottom and 15MW for floating platforms

Policy Drivers

2026 Outlook

Analysts project 420-450GW of solar, 130GW of wind, and 180GWh of storage deployment in 2026. Key risks include grid interconnection bottlenecks, permitting delays, and trade policy uncertainty around solar module tariffs. Opportunities lie in emerging markets, repowering aging wind farms, and long-duration energy storage commercialization.
