Solar surge kept fossil electricity flat in 2025 as China and India made ‘historic’ shift
In 2025, a record surge in clean power met all global electricity demand growth, with solar leading the expansion by meeting around 75% of new electricity demand alone. This shift, largely driven by China and India, outpaced electricity demand growth and led to declines in fossil generation in both countries for the first time this century. The rise in clean generation slightly exceeded demand growth, pushing fossil generation down by 0.2%. UN Climate Change head Simon Stiell emphasized the risks of fossil fuel dependence amid disruptions in global oil and gas supplies due to the war in the Middle East, urging nations to accelerate the shift towards clean energy to enhance national security, economic stability, and reduce exposure to fossil fuel imports and costs. Stiell highlighted that clean energy is cheaper, safer, and faster-to-market compared to fossil fuels, which are causing chaos in volatile energy markets.

The world added 605 GW of new PV capacity in 2025, says IEA
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.

Are long-promised solar perovskites finally hitting mass production?
Perovskites have the potential to significantly improve solar panel efficiency by absorbing more light than conventional silicon cells. Startup Tandem PV is working to bring this technology to commercial manufacturing with a new factory in California, aiming to increase energy production by one-third in the same physical space as regular solar panels. Their innovative approach involves using a smaller lab to test and refine their perovskite formula before scaling up production, with plans to start producing full-size panels in 2028 pending successful real-world testing. The production process of perovskite solar panels involves depositing layers of chemicals on glass, crystallizing the perovskites, and adding additional layers for electron transport and protection, all done in a highly automated manner for faster and more precise manufacturing. The ultimate goal is to produce panels that outperform those created in the lab, offering a promising solution for more efficient and sustainable energy production.

Solar, wind meet 99 pct of new global demand as batteries help deliver “round-the-clock resource”
In 2025, record amounts of new solar and wind generation capacity met 99% of global electricity demand growth, with Australia leading the charge in transforming solar into a "round-the-clock resource." Solar power saw a significant increase, meeting 75% of the net increase in global power demand and growing by 30% from the previous year. Wind energy also had a successful year, with the global industry installing a record-breaking 165 gigawatts in 2025. Together, wind and solar now contribute more than half of all global renewable generation, helping low-carbon sources reach 42.6% of total electricity generation in 2025. Battery storage saw significant growth, with prices dropping to $70/kWh and capacity additions increasing by 46%, surpassing natural gas additions. This shift towards clean energy signifies the beginning of a new era of clean growth, reducing reliance on expensive fossil generation and reshaping energy security by meeting increasing electricity demand.
