First track your meter readings and make sure they match up with your bill. Also look over your bill for "hidden costs". There may be a few fees you can avoid.
Then go thru your home. Things like a tv, computer should be on a surge protector. Make sure items you do not normally use are unplugged if possible. Try to see what things you can do to reduce your energy use. The biggest energy culprits are 1. Heating/Cooling, 2. Hot water heater 3. Fridge/Freezer. Make sure all three are running as efficiently as possible. They make up about 60% of you homes electrical usage.
With spring here, you can put a fan in your windows to keep the house cool. We do this thru the summer. Not only does it save us $ but we seem to be able to breath better. We buy two large powerful fans for about $40 each. $80 a summer is much cheaper than $300 a month elec bill.
A full fridge and freezer work more efficiently. If you dont have alot of food to store fill soda bottles with water and fill up your empty space. These also come in handy on those hot summer days :)
Turn the dryer off, and use the clothes line. Indoors or out doors hang as much as you can to dry.
Some people swear by CFL bulbs. I prefer incandescent for most uses. But we reduce to a 60 watt. When I need light, I need light and I have 100 watts on hand for those occasions ( like sewing).
Turn down your hot water tank, take shorter showers. Also if you can reuse bath water to water plants. ( I plug the tub and wash our cloth diapers while I shower.) Wash dishes by hand using a small bowl of soapy water in the sink instead of filling the sink with water. Rinse with cold water. Or only run the dishwasher when full.
There are many more ways to cut energy costs. What things have you done?
