Global electricity use efficiency improved by 1.5% in 2022 and that translates into big measurable wins, from 250 TWh saved by industry to 1,200 TWh from residential LED adoption reaching 60% worldwide. Yet the same power system still emitted 14.6 Gt CO2 in 2022, so efficiency gains and climate impact are moving on different timelines. This post pulls those tradeoffs and breakthroughs together, with results spanning smart meters, heat pumps, grid losses, renewables growth, and the emissions intensity of every major generation type.

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
