Do you love those displays of Christmas (or Hannukah or Kwanza or …) lights? Are you awed by those so impassioned that they string up 1000s of lights in awesome displays worthy of a city center? I once did, pausing on cold winter nights, white clouds issuing from my mouth, enjoying being in the glow of beautiful displays. And, in a way, I was inspired that they would spend $1000s (or $10,000s) on displays and the electricity to power them so that others could enjoy the sight on those cold winter nights.
But … no longer … not for awhile. Far too often nowadays, my winter evenings I can wear short sleeve shirts rather than bulky coats and gloves. And, energy is no longer a question simply of money. I’ve reached the point of feeling like a Scrooge; feeling outrage over the tons of C02 going into the atmosphere via neighbors’ 10,000 light displays rather than feeling ‘joyous’.
But, a compromise does exist; a path to cut sharply those CO2 emissions while still putting out those lights: LED lights. But, far too many are unwilling to spend the money upfront to cut their electricial use, reduce their pollution, and — actually — save quite a lot of money.
Within the home …
My household is dominated by Compact Flourescent Lightbulbs (CFLs) (see Making Energy CENTS — From the Home to the Globe) and light-emitting diodes (LEDs) in recessed lighting (excellent light and dims well, unlike CFLs). When going to dine with friends, in one hand is the bottle of wine and the other carries CFL bulbs (delivered/wrapped in reuseable gift/shopping bags).
The Holiday season brings me to extend this into the domain of decorative lighting — of replacing incandescents with LED Christmas lights.
In the hardware store a couple years ago, I was pleased to see real options for LED lighting; even if there were 20 times as many incandescents as LEDs. While stopping to admire the LEDs, I convinced two people to pony the upfront investment in LED Christmas lights. Those four boxes (what a signal achievement) were overwhelmed by the flow of traditional bulbs. The woman who had to buy 40 boxes for her new McMansion simply said that she couldn’t afford the LEDs.
How many pounds of carbon will go into the atmosphere to support her 4000 lightbulbs?
And, in pure cash terms, how much will she spend for electricity?
And, how many multiples will that be of the LED lightbulbs price?
But, she has the Walmartization issue of the sticker price rather than having any clue as to the long term implications of what she’s bought/buying. (emphasizing the Cost to Buy over the Cost to Own)
Calculating the cost
Hmmm — let us work the numbers and understand what is going on here.
100 old-style incandescents at 5 watts each = 500 watts
12 hours / day for 30 days: = 360 hours
One month of lights on all night: 180 kilowatts
180 kwh @ 8 cents kwh = $14.40
That is the traditional incandescent option, let us try this with ‘mini-bulbs’. which use roughly a tenth of that, or .5 watts each. Thus, that 360 hours of 100 lights would run $1.44.
And, then, there are LEDs, which cut the power required by another 90 percent: 100 LEDs at .05 watts each = 5 watts … (based on this LED lighting). Going through the same calculation …
1.8 kwh @ 8 cents kwh = $0.14 (actually, 14.4 cents)
At 8 cents per kilowatt hour (below the average domestic price in the United States), the incandescents cost $12.24 more per year to own/operate.
Traditional incandescents cost: $3.99/string (before tax)
LEDs: $26.99/string (price at an overpriced hardware store … easy to find online/elsewhere for under $15 and, with a little effort, under $10)
At $14.24 less per string per year, the LEDs would be paid
off in less than 2 years and keep on saving. (Thus, if bought for $15, the electricity savings pays for the LED string in just one year.)
And, if one is going to be putting on lights, traditional incandescents would put out roughly 250-300 pounds of CO2 in that month versus the roughly two pounds from LEDs.
And, of course, all these calculations are just for one string of lights.
The woman buying her 40 strings. That is $600 or so in additional electricity per year. And, perhaps 10,000+ pounds of additional carbon dioxide. Just, of course, for that one McMansion.
Driving around the community, 2500 light displays are not unusual and there are a few that must have over 10,000 lights. And, there are the public displays, including parks with miles of Christmas light displays. Just how much electicity is being burned and how much carbon going into the air to support these displays?
A holistic look at Christmas light options
Considering energy issues holistically, there are three basic areas:
1. Power Source
2. Efficiency of use of that power
3. What we use the power for
Starting with the last, what we use the power for (the desired usage), the objective here is to have Christmas lights, no? To have ‘beautiful displays’, no?
Moving back to the second, efficiency, the traditional path is using incandescents, which are not long-lasting, can cause fires, and use a large amount of electricity — especially when compared to the now widely available LED option. One can use a small fraction (a percent) of the power and achieve not just the same, but better (safer, easier to string, longer-lasting (will to grandchildren)) results
Finally, let’s turn to the power source. Roughly, 50% of US electricity comes from coal. Do we really want West Virginia mountaintops being razed for Christmas light displays? Is that desecration what the holiday is about?
Rational people don’t call for people to live in the dark — but do call on people to use CFLs, as much as possible, as a path to reducing electrical demand. This is a similar call for rationality …
By Jamaica Pond, in Boston, Dominic Luberto comes close to defining excess when it comes to lighting. Having spent over $10,000 on lights, just this year, he will have over 250,000 lights up. Estimated electric bill of $2000 per month (although, to be honest, this sounds like an embarassed understatement of actual costs).
“But, when you see the smiles on the kids … every penny is worth it.”
But, he hoped to cut into those costs. Now, he wasn’t planning to go with energy efficient, with LED lights.
But, does efficiency address excess?
Excess comes in many ways, from executives abusing the shareholders trust to eating far too heavily at a holiday table. We can shop excessively (credit-carding ourselves to debt) as individuals or a society. With some excess, we hurt no one but ourselves; other excess, such as executives, comes egregiously at the expense of others. Some excess, perhaps the executives, comes with a delusional concept that what we are doing is for the greater good. Sometimes that is true … dependent on how that “good” is defined. And, excess often occurs with a focus on the present over any thought toward the future.
How do we rate Dominic’s excess?
His electric bill this month runs $1,900. He claims that NStar may help ease the tab next Christmas, but an NStar person says no, the much-reviled utility won’t be picking up his tab
“Much-reviled”? In other words, NStar get your act together and help subsidize this energy profligacy. In fact, they already are, as they’ve had to install additional electrical equipment to support his light displays.
Every year, the lighting goes on earlier (now Halloween) and stays on longer (through the end of January).
Mr. Luberto says he does it “for the kids.” He believes that the tradition of Christmas lights is dying and he’s out to revive it single-handedly. “They love it” he insists. Not all his neighbors do, however. They complain of not being able to sleep for all the super-bright light pouring in their windows; they complain of not being able to get into or out of their driveways due to the crush of traffic up and down their street all night, they complain that the display is just plain vulgar.
Dominic Luberto is not to be disheartened. His goal is to have a house that can really be seen — from space.
The traffic, of course, is an additive pollution cost encouraged, of course, by all the press. The Boston Globe’s article: The Shining: It’s worth a trip, the light fantastic.
Every evening, families pour out of SUVs and minivans to get a dose of the wonder of it all. The cars, sometimes by the score, pull over to the side of the road, their emergency blinkers on.
From WBUR’s recent story
DOMINIC LUBERTO: I don’t go half way, I go all the way or I don’t do it at all, and that’s the way people should do it, if you’re going to do something just do it right, go all the way and do it right.
One reaction to Luberto’s display, from Boca Raton, Florida,
At the risk of being labeled a Grinch or Scrooge himself, given the urgency of our climate change situation, perhaps it is time to seek moderation and find new ways (or old — candlelight perhaps) to celebrate this magical time of year. Or perhaps people can choose to offset the increased usage through alternative energies or carbon credits. After all, and it seems Luberto has pre-empted me on this one, “it’s all for the kids,” and what world we leave for them and their children.
For a good collection of Luberto stories, see Universal Hub. See Ecomorons for a contest as to the worst Christmas light excesses (and their post on Luberto).
As I walk my overly warm neighborhood, with many homes lit up with 1000s of lights starting to appear and staying on all night, holiday lighting excess is on my mind as per Christmas Lights: melting away a White Christmas.
Sadly, Dominic is not alone in his excess.
Celebrate holidays without desecrating the earth …
A simple question to ask: How much pollution is a string of lights worth?
We will be in a far better situation when people celebrate through taking a deep breath of fresh air rather than adding those tons of C02 with 24/7 light pollution.
If you love Christmas lights, it is time to get rid of those incandescents and replace them with LEDs. They are available on online and in an ever growing number of stores.
By the way, there are even more benefits to LEDs as, due to the lower power requirements, the LEDs can have MUCH longer strings (easily 10x the bulbs in one string), are FAR less likely to cause fires, are nearly indestructable, and last FAR longer (probably would be working 50 years from now).
Thus, again, if you love Christmas light displays, buy yourself a gift and replace your incandescent strings with LEDs.
Your pocketbook will thank you.
Earth will thank you.
As, for me, a true tipping point in the battle against Global Warming will be when I don’t feel like Scrooge and we start pulling the plugs on non-LED lights.
And … some notes
PS: See Making Energy CENTS from the Home to the Globe for a discussion of how I discovered that my CFLs were providing me a 200% Return on Investment (ROI) every year, year in and year out. Considering how my 401k has transform to a 301k and then a 201k, that ROI is pretty good.
PSPS: I don’t want to be advertising, but there are MANY options out there for LED Chrismas lights. Without endorsement, Environmental Lights (”280 LED Christmas light string products to choose from”); Christmas Lights Etc; 35 light sets typically below $10 per string; 1000 bulbs.COM; Inirgee, and, well, so on … They are easy to find, online and in stores, if you’re willing to look. And, if you want to go all out and eliminate that electricity cost while making a statement, there are solar-powered LED Christmas light options (which really pay off if you want to put lights far from an electric plug, “off-grid”, so to speak).
