The International Energy Agency's latest report highlights the significant increase in solar PV electricity generation in 2025, with a total generation of around 2,800 TWh. Solar's share of global electricity generation has surpassed 8%, with solar covering 605 GW of new renewables capacity. Solar met more than 25% of the higher global energy demand, marking the first time a modern renewable source contributed the largest share of energy demand growth. Battery storage is identified as the fastest growing power technology, with lithium-iron phosphate batteries dominating the market and an increasing number of projects being deployed for longer durations to provide flexibility in systems with rising shares of PV.
