Renewables now provide 30% of the world’s electricity, and 2023 delivered 2,807 TWh of renewable generation that grew faster than overall demand. Solar PV pushed total global capacity to about 1,600 GW with 510 GW of additions, while wind reached roughly 1,000 GW after 116 GW came online and became the second largest source of new renewable capacity. The investment and cost trends are just as striking, including $473 billion spent in 2022 and wind LCOE scenarios dropping to about $0.02 to $0.05 per kWh, alongside the real-world challenge of integrating variable generation.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
