New York, New Jersey, Ohio (NY and NJ were affected by the blackout a few years ago, caused by a toppled tree in OH).
California (it bought its electricity from out-of-state brokers, causing the crisis that toppled Gray Davis).

Texas is the lone star state because it was an independent country for a short time, with one (lone) star and two stripes on its flag.
(My appologies if you were insulted before – I was only poking fun at myself.)
