Global Solar and Wind Power Generation to Grow 20% in 2026 Driven by AI, Energy Security
The International Energy Agency projects global solar and wind power generation will increase by 20% in 2026, with an average annual growth of 15% through 2030 under current policies[1]. China will lead solar growth at 94% from 2026-2030, while Europe faces grid constraints but advances via the EU Grid Package[1]. In the US, AI-driven demand positions renewables as a bridge to gas and nuclear, boosting tech companies’ renewable purchases[1].
Battery Storage Capacity to Surge 31% Annually Through 2030 Amid Renewables Expansion
Battery energy storage systems (BESS) costs have fallen 61% from 2020-2025, with continued declines expected in 2026 to support solar and wind intermittency[1]. Global installed BESS capacity is forecasted to grow 31% annually through 2030, led by China at 46% share in 2026, while US solar developers plan to pair storage with over 50% of projects by 2030[1]. The US will add nearly 15 GW of new BESS in 2026, concentrated in Texas and California[8].
Hybrid Energy Storage System Wins CES Award for High-Efficiency Grid Support
The HESS combines aero and hydro technologies to achieve 80% round-trip efficiency, surpassing traditional CAES (50-70%) and rivaling lithium-ion batteries at 86%[2]. It requires one-tenth the space of pumped hydro, stores over 1,000 MWh for more than 8 hours, and mitigates grid instability from renewables[2].
Energy Storage Shifts to Longer-Duration, Non-Lithium Tech for AI Data Centers
In 2026, battery tech diversifies toward longer-duration storage, safer non-flammable chemistries like flow batteries, and resilient supply chains amid AI and data center demand[4]. Standalone storage gains value for grid stability and data centers, with flow batteries suiting frequent cycling over degrading lithium-ion
