For the fourth year in a row, the world is projected to add a record amount of wind and solar. If the growth of these technologies continues apace, countries will reach an international goal to triple global renewable capacity by the end of this decade, analysts say.

From 2023 to 2025, renewable additions grew by 29 percent each year, according to figures from Ember, an energy think tank. To meet the tripling target, analysts say, additions need to grow by just 12 percent each year from 2026 to 2030.

Currently, however, national targets are aligned with only a doubling of renewable capacity by 2030, raising concerns that governments will fail to build the infrastructure needed to bring more wind and solar power online.
