The IEA’ s Renewables 2025 outlines global clean energy growth and supply chain decarbonisation – calling for market reform and grid flexibility
The IEA Renewables 2025 report sets out clear progress on renewable energy and the decarbonisation of supply chains. Since 2010, the world has added about 2,500 GW of non-hydro renewables, largely in fuel-importing economies, strengthening energy security and resilience. Those additions helped energy importers avoid an estimated US $ 1.3tn in fossil fuel costs between 2010 and 2023.
Procurement strategy is pivotal to this as market-based routes including corporate PPAs and merchant projects now drive a far larger share of growth as policy reforms in China and sustained deployment in Europe bring projects forward.
Supply chains are the pressure point. PV manufacturing has swung into overcapacity, forcing average global module spot prices down to roughly US $ 0.09 / W in 2024 and pushing margins negative. Price fragmentation persists where trade barriers apply.
Integration challenges are also growing. Curtailment and negative prices have become more frequent in markets with high wind and solar shares, exposing the need for storage, flexible demand and the capacity to stabilise systems.
The report links emissions and cost reductions to strategic procurement and grid flexibility while warning that concentrated mineral supply and grid constraints must be addressed to sustain momentum.
“The growth in global renewable capacity in the coming years will be dominated by solar PV”
