Electricity, or how I saved over $500 this winter

You may recall in Part 1 on Natural Gas, I outlined how I saved $166 on my natural gas bills over a two month period versus the previous homeowner (standardized against winter temperature differences) with little to no effort and less than $100 in supplies. That number has now increased to over $400 in savings from September 2006 through March 2007…

Now I’m happy to report that I got the electricity data on the previous owner as well, and frankly I’m not sure how she used so much electricity in our little house – she used as much in one month as we expect to use in a whole year. But the data doesn’t lie and over the same 6 month winter time period, i.e. no air conditioners or dehumidifiers to skew the data, we have saved an astonishing $516 over her previous bills in the same 6 months the year before…Our monthly bills are $25-$35 in the DC metropolitan area (we’re paying 13 cents/kWh on average). It’s incredible how easy it is to save electricity, money, and pollution.

As before, your first thought must be that I’m sitting in the dark or bought all new appliances. Nope. The porch light greets us when we come home, we hang out in various rooms in the evening without much thought to turning the lights off, and we haven’t replaced any major appliances (same refrigerator, dishwasher, laundry, etc).

Here are my secrets, not exactly rocket science, which cost less than $100 and only a little effort:

• Replaced all lights with CFLs – Every one. The light is the same. They hardly burn out. Friends can’t tell the difference. The trick? Don’t buy the $2 cheapie and expect it to put out the save amount of light. Pay $3 for the one with the most lumens, i.e. the 100 watt replacement (use these where the bulb won’t be visible), and/or the ones with the fancy cover so it looks like a regular bulb (use these where the bulb is visible). You can get really small ones and specialty ones for vanity lights that work great. Some (not all) may take 5 seconds to warm up and reach full brightness but is that too much to ask? Prioritize the lights that are on the most (not the ones in the closet) if you don’t want to replace them all.
• Light sensor on the front porch – I don’t like to come home to a dark porch. So I paid $10 for a light sensing socket and screwed it into the old socket on the porch. Sun goes down, light comes on, and it has a timer to turn itself off after 2, 4, 6 hours (or the next morning).
• Phantom Loads – There are a lot of things that are “on” even when “off” – anything with a remote control, a fat box for a plug (a transformer that converts AC to DC), a clock, cell phone chargers, printers, monitors, etc. We have 2 or 3 power strips that allow me to shut off 3-4 things at once where it’s convenient, or we unplug them. But it’s not practical to do everything – I don’t like to reprogram the VCR, TV, microwave clock, etc so I don’t bother. I do unplug the clock radio in the guest room when no one’s there (that thing uses $24/yr alone) and the chargers that don’t get used everyday. Get a Kill-a-Watt and use it to go around the house and test different appliances (or better yet, buy one with some friends and pass it around to share costs). You will be surprised how many of these you have…

That’s about it…surprisingly simple. Other things you can do:

• Switch to natural gas appliances – As you replace your old appliances (if they break or you remodel), switch to natural gas. It’s cheaper and cleaner for the most part (even with the higher natural gas prices recently) – stove, dryer, and water heater. After all, electricity production is about 30% efficient and mostly comes from coal. I found a free natural gas dryer on Craig’s List a few years ago at my old house. An electric water heater alone probably costs over $500/yr to operate – that’s more than it costs to buy it.
• Buy Energy Star appliances – As you replace your old appliances, pay a little bit more for ones with the “Energy Star” label. They are more efficient and save more money in the run. Don’t necessarily replace the appliances if they still work (although a new refrigerator over one that is 10 years or older could easily save over $100/yr). The “big four” users are refrigerator, dehumidifier, central air conditioner, and electric water heater.
• Buy a window air conditioner – We haven’t gone through a DC summer yet, but we plan on using the air conditioner at some times…but there’s no reason to cool the whole house at night, so we’ll use a window air conditioner for our room and shut the central air off. Use a fan at night if it cools down – even 4-5 use less than the air conditioner.
• Refrigerator details – Turn off the ice maker. We don’t use much ice and don’t feel the need to have 2 gallons of it available at all times, so I turn it off once it’s filled (and it usually stays off for 2-3 months actually). And if you buy a new refrigerator, the top/bottom door styles are more efficient than the side-by-side doors. Refrigerators can easily use less than 500 kWh/yr now versus 1500+ a few years ago (hurray for federal efficiency standards).
• Don’t replace the windows for energy reasons – As before, do it for aesthetics. Do it for comfort. Don’t do it expecting to save oodles of money and run from anyone who says otherwise.
