well it depends on ur electricity habits.do u run ur air conditioners? how about a habit of leaving house lights on? at first i thought it was the fish lights when bill here ran for 417$. i tried my best to turn of lights unused, switched to low watt floursent bulbs instead of reg bulbs and used heavy electric equipment during conservation hours i think here its 9pm-7am.(like pool pump, washer dryer). as well as turned off computers when not in use, no not on standby, either hibernate or shutoff. well the point is when i changed my habits the bills began to decrease even with about a total of 1000watts running for my system (all equipment plus lights). from 417 to 383 to 334 to 284. on an average it goes around the low 300s.
