My first 800 kwh is 6.232 cents/kwh. Then it goes to 9.599 cents/kwh. There is no basic service charge.
If you have an electric water heater, the way to save energy is with a water saving shower head. I have a 35 gallon water heater, and we never run out of hot water. Energy star dishwasher and front loading washer help. All the lights are either CFL or LED, but lighting is a trivial part of our electricity use. Heat and AC use quite a bit, so we installed new doors, windows, upgraded insulation, and honeycomb blinds. Upgrading the insulation, doors and windows made a big difference in the comfort of the home. The furnace ducts, including the big return air duct in the attic, were uninsulated when we bought the place. The plumbing was not insulated. The windows were single pane aluminum frame, and so was the sliding glass door to the deck. There was no subfloor insulation and a plumber had butchered a 12" hole for the tub drain into the crawl space.
Switching to LED TVs and computer monitors run by energy efficient laptops made a big difference. The 500 watt tower went to a 50 watt laptop. Electricity is our only utility bill, and we pump our own water among other things. Our bill runs about $125 a month.
