I just posted the first part of a two-part feature about America's electric grid and the risk of blackouts. If this is something you're interested in, though, there's a New York Times piece from last week that you should really read.
When we lose our access to electricity, there's usually more than one thing that went wrong. But, one of the common things that does go wrong, especially in recent years, is extreme weather. The way the grid was built, and the way we manage it, was set up with predictable weather and climate norms in mind. When those things start to drastically shift—as we've seen over the last 10 years—the grid becomes vulnerable.
And electricity isn't the only infrastructure affected.

On a single day this month here, a US Airways regional jet became stuck in asphalt that had softened in 100-degree temperatures, and a subway train derailed after the heat stretched the track so far that it kinked — inserting a sharp angle into a stretch that was supposed to be straight. In East Texas, heat and drought have had a startling effect on the clay-rich soils under highways, which “just shrink like crazy,” leading to “horrendous cracking,” said Tom Scullion, senior research engineer with the Texas Transportation Institute at Texas A&M University. In Northeastern and Midwestern states, he said, unusually high heat is causing highway sections to expand beyond their design limits, press against each other and “pop up,” creating jarring and even hazardous speed bumps.
The frequency of extreme weather is up over the past few years, and people who deal with infrastructure expect that to continue.
