There are two situations which do not require you to be heating your home: when it is warm and when you are not at home. Since it is still a bit chilly outside, you may want to consider setting up a routine of turning down the set temperature on your thermostat when you head out in the morning and when you go to bed.
Some large electronics can use as much energy as a light bulb while in "stanby" mode, meaning you should unplug them when you leave the house or know you won’t use them for awhile.

CFLs use 75 percent less energy and last 10 times longer than an incandescent bulb. I know that when I purchased new lamps for my house, they had a whole shelf of incandescent bulbs right next to it, and I had to go search the store for CFLs, so I understand if you are currently using incandescent bulbs. But it’s worth the switch — not only are CFLs equal in light quality, they last way longer and will save you hundreds of dollars over their lifetime.
