Mine's $200 per month (level pay plan) but may go up next year. That's for a three bedroom house with a pool.
THAT LIGHT ISN'T GOING TO TURN ITSELF OFF is what my kids hear the most
I've done allot over the years to make the place more energy efficient. Not to save $$$ (the payback usually isn't there) but to make the place more comfortable. Double-pane windows, as patio cover on the back of the house, better insulation, sealing up cracks and drafts, dimmer switches, solar heating for the pool, a high efficiency variable speed main pool pump with a smaller booster pump for the sweeper, high efficiency AC condenser/compressor, etc.
