Turn It Off
It may seem obvious, until you've followed a teenager or absent-minded spouse around the house, flicking off switches. I used to come home and find every light in the place on - with my ex sitting in front of the TV, oblivious to the world. Once he started paying the electric bill, he got over that one right quick!
The rule became, simply: "If you turned it on, going in; turn it off, going out." The cats didn't care if the bathroom was dark. And they could certainly hit the bed without benefit of light.
We probably cut the bill by a good 30% after he started paying attention. The downside? Three of the four cats loved to pounce on unsuspecting feet from the relative anonymity of a dark hallway. Still, peroxide and band-aids were cheaper than the electricity.
Don't Turn It On
This was my personal contribution to the ever-growing electric bill. I habitually had the television on for 'company' or background noise. Silence really bothered me.
It, admittedly, took some adjusting. But with the help of a small radio that I centrally located on top of the fridge, I could have my 'company' and not hammer the electric bill. I even sang along and seriously confused the cats!
You've never lived until you have a cat want to look into your mouth to see where that gawd-awful sound is coming from. {sigh} Everybody's a critic!
Better Bulbs
Currently, we have two lamps and a wall fixture in the living room; a fluorescent unit in the kitchen; a ceiling fan and bedside lamp in the bedroom; and a bathroom fixture with enough wattage to give you a tan. Seriously! The thing actually heats up the whole bathroom!
But mostly, we use little strategically placed nightlights. There's one each in the kitchen, living room, bedroom, and bathroom. They use very little electricity and provide enough light for most purposes.
The rest of the fixtures (bathroom tanning salon, notwithstanding) have CFLs. While these bulbs are more expensive than standard incandescent bulbs, they (as I'm sure you know) last a long time and use a lot less electricity. (60 watts vs. approximately 18 watts, depending on the bulb, for the same amount of light.) We buy a bunch at a time, either at the local dollar store or the corner drug store, when they're on sale.
I'm going to look for some that will fit the bathroom fixture. Before my retinas (retinae?) are completely fried.
Appliances
Refrigerator/Freezer
One thing we noticed, living in a small apartment, is how often the refrigerator turns on. Since apartment complexes don't always go for the latest energy-efficient appliances, it's a safe bet that this puppy is an electricity hog. But, that's easily dealt with.
Ours has a single control for fridge and freezer. Starting just above the middle of the range (1-9 in this case), we adjusted the setting slightly warmer. Keeping a close eye on food in the freezer and milk in the fridge, we continued adjusting over several days, making certain everything stayed frozen, or good and cold without freezing.
Ideally, a freezer/fridge thermometer should be used to verify the temps are no higher than 0° and 35°, respectively. (Do the same for a chest or upright freezer.) Otherwise bacteria continue to grow and you run the risk of food poisoning or simply ruining the food.
Dishwasher
We don't have a dishwashing machine. {sigh} If you do, and I'm pretty sure I hate you, there are ways to reduce power usage. Don't run partial loads. It takes just as much electricity to run a half-empty dishwasher as it does a full one, and you'll be running it more often.
Use a shorter cycle, if your machine has one. There's a huge difference between light load and blast-the-teflon-off-the-pans. Run the dishwasher at night, when rates tend to be lower.
Don't use the dry cycle, if you can avoid it. Letting the dishes air-dry overnight uses, on average, about 1,000 fewer watts. And if you don't have a dishwasher that heats the water, don't get one. They use about 3,000 more watts of electricity per load.
Clothes Washer
Obviously, an EnergyStar-rated appliance is the best bet, with front-loading washers beating out top-loaders. If your budget looks like our budget, trading up is probably not an immediate option. Other than replacing what you have, there are a number of things that will help with these two meter spinners.
Use the coolest water temperature you can. Most of the power needed to wash a load of clothes goes into heating the water. No matter what the wash temp, I always rinse in cold water. Adding a cup of vinegar to the final rinse helps get the soap out, eliminating the need for an extra rinse cycle.
Unless clothes are absolutely walk-to-the-machine-on-their-own filthy, try a shorter cycle. From what I can tell with our machine, most of the time spent (per load) is waiting for the darn thing to fill up. But anything that reduces the power consumption, while still getting the clothes clean (kinda the point, huh?) is good.
Clothes Dryer
When it comes to drying clothes, you're really talking the electricity grabber of the pair. Ideally, hanging everything to dry (like my mom and grandma always did) is the best option. Zero energy use! We don't have the space to do that, so a clothes dryer is a necessity.
With that said, don't overload the dryer. Our apartment-sized dryer is, oddly enough, a little smaller than our washer. To compensate, I don't throw in a whole load. By putting in a few items, pulling out the dry and adding the damp, it actually takes less time to get everything dry enough. (I also try to hang the jeans or towels, etc. that are waiting their turn, so the air starts drying them for me.)
Which leads me to another energy saver. Anything that ends up on a hanger, in my opinion, doesn't have to be dry as dust. As long as clothes aren't crammed and jammed together, the circulating air in the closet will finish drying things before there's a risk of mildew. And overdrying actually contributes to excessive wrinkling in a lot of fabrics.
Unplug It
This one's a toughy, for us. We have a lot of electronics and small appliances. Even when they're not in use, many are still drawing some electricity. (My cell phone actually tells me to unplug the charger when charging is complete to save electricity. Cheeky brat!)
Not everything that plugs into the wall, mind you. But, anything with a clock or always-on light uses power all the time. Just less when it's only sitting there looking pretty. (Mr. Electricity explains it in much better detail than I can.)
Almost all of our 'stuff' is plugged into a surge protector. I have been considering routinely turning off the strips when we shut down for the night. Unfortunately, I'll probably have a few meltdowns when the coffee pot fails to turn on in the morning. (I'm not at my best and brightest when I first wake up.)
Don't Heat/Cool It All
If you wandered over to visit Mr. Electricity, you've noticed that - far and away - the biggest energy hogs are heaters and coolers. That furnace or A/C unit will make the meter spin like a whirling dervish. It's actually rather scary!
We don't heat or cool every room, all the time. During the day, only the living room vent is open; at night, only the bedroom. And keeping the thermostat below toasty or above frigid makes a huge difference.
If you have a bigger place than we do (not difficult to imagine), space heaters and ceiling fans use a lot less power. Just make sure the heaters are off, if you're not in the room. And watch the kids around them. Of course, a few well-placed afghans to throw over your legs or across your shoulders, as well as on the bed at night, keep you nice and cozy without any electricity at all.
(Aw, come on! You knew I was gonna go there!)
