Sustaining a City in a Long-Term Power Outage

A few comments on this fascinating study from Pittsburgh (site of Carnegie Mellon, which is a center of excellence at studying critical infrastructure issues).  The key theme that emerges for me is the interaction of the liquid fuel system (particularly diesel) and the electricity system.  In a short outage, lots of critical infrastructure has diesel generator backup, and so the hospitals, 911-call centers, and so on can continue to operate.  However, they typically have limited fuel storage capacity (if for no other reason than that diesel doesn't keep indefinitely), and so in a long outage, the availability of diesel becomes critical to keeping everything together.
