Ember said the world is on track to add record renewable capacity again in 2025.
The think tank said monthly solar and wind deployment data to September indicate 793GW of additions in 2025, up 11% from 717GW in 2024.
Ember said this builds on growth of 22% in 2023 and 66% in 2022.
The group said solar additions are projected to rise 9% and wind 21%, with solar growing more in absolute terms.
Ember said China is set to account for 66% of global solar additions and 69% of global wind additions in 2025.
The organisation said that after strong growth in 2023 to 2025, additions now need to rise by 12% per year from 2026 to 2030 to meet the tripling goal.
Ember said governments’ current 2030 targets align with only a doubling of capacity and create uncertainty over achieving tripling.
The group said the latest IEA renewables main case points to a 15% capacity shortfall to tripling by 2030 and a 28% shortfall in generation.
