Do a nightly energy sweep
We all have left fans, lights or appliances on at night while we sleep, but doing so wastes increasingly expensive energy.
To save money, do a nightly sweep through the house to make sure all your electric devices are turned off before you go to bed. It may be a pain, but the savings from simply turning everything off can add up quickly. It takes about $9 per year to run just one compact fluorescent lightbulb through the night, $21 for a conventional bulb and $35 for a big ceiling fan on high, according to the energy calculators at MichaelBluejay.com.
