Quantify the scale and pace of global renewable energy capacity expansion projected through 2030 based on IEA Renewables 2024 data, assess gaps between current national policy trajectories and the COP28 tripling target, and identify structural barriers to accelerating the energy transition.

Synthesis and analysis of IEA Renewables 2024 flagship report data (published October 9, 2024), cross-referenced with IEA World Energy Outlook 2024 projections. Data covers installed capacity forecasts, manufacturing capacity analysis, cost trends, and regional breakdowns across 2024–2030 scenarios.

The IEA Renewables 2024 report projects over 5,500 GW of new renewable capacity additions globally between 2024 and 2030 — nearly 3x the increase seen between 2017 and 2023. China will account for ~60% of global additions, holding nearly half of world total renewable capacity by 2030.

Global solar PV manufacturing surpassed 1,100 GW by end of 2024, more than double projected demand, causing module prices to fall over 50% since early 2023. Solar PV capacity in the US and India is forecast to triple by 2030, but production costs remain 3x (US) and 2x (India) those of China.

Key barriers include grid connection queue backlogs, permitting delays, and financing access gaps in emerging markets. Under current policies, the world approaches but does not fully reach the COP28 tripling commitment, requiring accelerated policy action.
