Electrical fires caused $1.4 billion in US home property damage in 2021, and the losses do not line up neatly with what people expect from “simple” malfunctions. Faulty wiring, overloaded circuits, and damaged cords drive the residential picture, while switchgear arcing in substations and inverter or UPS failures shift the risk across utilities and critical facilities. By the time you factor in injuries, response costs, and the role of night and seasonal use, the pattern gets much more complicated than most homeowners or facility managers assume.

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
