Any suggestions on how to lower my household electric bill?

Turn lights off whilst not in the room
Get energy saving light bulbs
Don't boil a full kettle every time, just boil the amount of water needed
Turn all appliances off standby at night
Wash your clothes on a 30 degree wash
Don't use a tumble dryer at all, dry clothes outdoors or get a maiden (clothes horse, I don't even know what the real name is for it).

By doing all these not only will you save money, you'll help save the planet aswell.

Seal up your house.
Get a programmable thermostat for your water heater or turn it off when not using a lot of hot water for a while.
Shut down your PC as much as possible when not in use. If not, at least turn of your monitor.
If you live in a hot climate, use your appliances at night time.
Use energy saving lightbulbs and don't leave lights on in rooms not in use.
Unplug chargers when object charged.
Turn up the temp in your home when you leave.

turn off all unecessary stuff, turn your heat down, use a clothesline to dry clothes. dont use many lights

Use candles instead

2) "Here are some proven ways to reduce energy costs:
Set your thermostat at 68°F in winter, 78°F in summer. Then adjust the settings as needed. Every degree you're able to "dial back" saves from 2-3 percent on heating and cooling energy.
In summer, avoid adding heat and humidity to your home during the daytime hours. Schedule cooking, laundry and bathing in the early morning or late evening.
Open south, east and west curtains in winter for auxiliary solar heat. Close them in the summer.
Have your heat pump, furnace and central or room air conditioner tuned up prior to each heating and cooling season.
Clean or replace filters monthly. Make sure the outdoor condensing unit for your central air conditioner, window air conditioner or heat pump is clean and unobstructed.
If your home will be unoccupied for more than two or three hours, reset your thermostat to 80°F in summer, 60°F in winter. Or, add an automatic setback thermostat to control both your heating and cooling systems while you're away from home.
Avoid operating your heating/cooling system fan continuously. While constantly circulating air may feel more comfortable, the small benefit may be offset by an increase in your electric bill.
"Tighten" your home with insulation, caulking and weatherstripping.
As older appliances wear out, especially heating and cooling equipment, replace them with new higher efficiency models."

IF you own, or otherwise have permission to make alterations, you might be able to add small windmills and solar cells to your roof to give you some of your power for free.

You can switch to more efficient electrical items, so your power usage is slightly lowered for the same electrical functions.

IF your heat is from electricity, then massive insulation will decimate power usage for heat - raise it up to an "R" rating of R-2,000 from the normal R-15 to R-20 of most homes.

Make an effort to minimize your power consumption ... catagorize all your electric items to one of three lists :

1 - Must use

2 - Should use

3 - Could use

... and go from there ...

Do the washing / water heating at night or in the evening.
Boil one kettle before surise, and put in a flask for the day.
Use candles instead of lights at night.
Use no light at twilight.
Save on showers and baths by using rivers and / or the sea.
Dont have a freezer and eat more fresh food

Switch to gas?

Make sure your home is well insulated. It doesn't matter what sort of climate you live in, it will save on heating in the winter and AC in the summer. Just think, if your home was 100% insulated (impossible I know) you would never have to heat it and all the AC would have to do is remove your body heat and heat from cooking, etc.

Try switching to another provider who is cheaper.

Well...lower the temp on your water heater, turn off lights that don't need to be on, use lower wattage bulbs, don't run the AC all day (althouh in florda that can be hard), maybe look into having a guy come in to make sure you're power is being used efficiently, and hang dry your clothes

Don't use the computer as much :p

Move in with someone else in the winter and turn everything off. Come back in the spring when you won't need heat or air conditioning. Don't cook on your electric stove too much. Eat lots of salads, jello, buy your bread, use your microwave oven. Don't leave any lights on at night, only the 1 watt lights so you don't trip at night. Turn the heat off at night, in case it you have to use heat befor you move out.
