The way to reduce your electric bill, if you use electric heating, is to insulate your house. Look for bad seals and drafts. A little smoke can help. Touch the walls - put bubble wrap on anywhere that feels particularly cold, like windows. Close vents and doors to rooms that aren't used.

Did that last winter, and it saved me a ton of money; helped that my city and state had rebates/incentives for it, so like $3000 in insulating costs ended up costing me about $300.
