Stuart at Early Warning has a post pondering if increasing extreme weather events are causing more frequent power outages - Extreme Weather Possibly Increasing Power Outages?.
I'm reading up on the economics of power outages at the moment, and I stumbled across the graph above in this National Wildlife Federation analysis. It shows the number of power outages caused by non-weather related factors, and weather related factors (from 1992-2010 in the US). There has been a material increase in both categories, but much more so in the weather related problems.
