Terms of Use 
For quick cost cutting on your electricity bill, try this:
Contact your utility company. Many offer a free home-energy audit. You may find that making simple changes like running the dishwasher at night rather than during the day could reduce your electric bill by up to 40 percent. Off-peak rates and other options can save you $100 a year.
Be sure to check out the savings possible under "load management" programs, too. With these programs, you can get discounts on your electric bill just by allowing your utility company to put a device on your water heater and air conditioner that switches them off briefly during periods of high demand.
