Here in Dardenne Prairie, MO (a suburb of St. Louis; see what WikiPedia has to say about it) our electricity is supplied by the Cuivre River Electric Cooperative. CREC surprised me this month with a genuinely informative addition to the data on the bill: a graph of usage over the last year.
My expectations of utility companies, most of whom operate as monopolies, have not been high. CREC, though, in addition to do a good job supplying electrical power (without the long outages that have plagued the next county over), supplies data which may help me figure out how to consume less of their product!
Of course I already knew we use far more power in the summer than in the winter; but to quantify that amounts I would have needed to sift through a pile of old bills. Seeing this chart, I wonder why our baseline (winter) usage is so high; I’m inspired to get out my Kill-A-WATT and investigate.
