In 2012, American homes captivated 3.65 billion kilowatthours (kWh) annual of electricity—up from 720 actor kWh in 1950—more than bifold per domiciliary than our British counterparts, and added abandoned to China. How did the American home become such an activity hog, admitting so abounding advances in able accessories and construction? Blame the American Dream.
Electricity Burning by the Numbers
That 3.65 billion kWh is just allotment of America's absolute anniversary activity consumption, but it is overwhelmingly active by the residential and bartering sectors. According the the US Department of Energy, the residential area abandoned consumes 37 percent of the absolute electricity production—that's an boilerplate anniversary burning of 10,837 kWh, or 903 kWh monthly. Louisiana association captivated the a lot of electricity in 2012 with 15,046 kWh, while Maine captivated the least, just 6,367 kWh, admitting this is due partly to LA's all-over electrically-driven A/C units and Maine's opposing assurance on heating oil.

In the residential sector, a lot of of the electricity is acclimated for air conditioning, refrigerators, amplitude and baptize heating, lighting, and powering accessories and equipment. You known, all of conveniences of the avant-garde home that the 1950s promised us. Per the EIA, the electricity acceptance of an boilerplate American domiciliary break down like this:

There are some absorbing numbers to agenda in the table above. For one, a ample allotment of our burning goes arise befitting our homes lit and cool. That's anon impacted by the boring growing attic affairs of American homes (which we'll altercate added shortly). Second, televisions and set-top cable boxes abandoned blot down 93 billion kWh annually, added than bifold what we absorb active our home computers (we'll altercate this added in a added as well). But a lot of importantly, about a division of our electricity use goes arise charging carriageable electronics and added assorted gadgets. The adaptable anarchy may accept freed us from ability cords, but abandoned temporarily.
And while US electricity burning has exploded back the boilerplate of the endure century, we arise to be extensive bazaar saturation. Consumptive advance has slowed from 9 percent year over year in the 1950s to just beneath 2.5 percent at the appendage end of the 1990s. Analysts apprehend the bulk to abide to bead down to about 0.8 percent by 2035.
However, even as American burning advance slows, the bulk of electricity burning away is rapidly expanding. In 2008, non-OECD nations (underdeveloped countries not affair to the 1960 UN Convention on the Organisation for Bread-and-butter Co-operation and Development) captivated 47 percent of the world's absolute electricity supply. By 2035, these nations are accepted to absorb 60 percent of the world's accumulation as they advance avant-garde industries and infrastructure.
On the added hand, the boilerplate British home captivated just 4,227 kWh in 2012—less than bisected of the American average. According to the UK Department of Activity & Altitude Change:
Between 1970 and 2012, electricity burning from customer electronics added by 376 percent, wet accessories by 151 percent and algid accessories by 96 percent. Home computing, which had no recorded activity use in 1970, rose to 587 ktoe (11.63 actor kWh) in 2012.
Since 1990 electricity burning from customer electronics added by 77 percent and wet accessories by 26 percent, whilst electricity burning from lighting accessories and algid accessories fell by 14 percent and 21 percent respectively, absorption bigger efficiency. Home accretion rose by 409 percent amid 1990 and 2012.
Overall, the boilerplate electricity burning of British homes grew just 1.7 percent per year amid 1970 and 2012. So how does the boilerplate American domiciliary still administer to use 2.7 times the electricity than the British home admitting a downward trend in absolute and per-capita activity use in contempo years?
How We Got Here

There are a bulk of accidental factors to America's aggrandized home activity use compared the the UK. For one, the British altitude is abundant added balmy than the United States—the UK doesn't accept intolerably clammy acclimate of Florida or the bitterly algid winters of the Northeast—and, as such, UK homes about do not apply home A/C units (which annual for 19 percent of American home consumption). Far beneath British homes own tumble dryers compared to the US, too. According to a contempo analysis by OPower:
Whereas 85% of US homes own energy-gulping dryers, the UK gets by on a 57% dryer ownership rate. And analysis abstracts from Opower's UK-based barter reinforces their about abundance with actual sans tumble dryer: in our abstracts sample, UK barter who embrace adhere dehydration far outnumber those who don't — by a arrangement of 14:1.
And it's not just clothes dryers and A/C units. British accessories are aswell bound outpacing their US counterparts in agreement of efficiency. In the UK, chest freezers now absorb 66 percent beneath activity than they did in 1990, cocked freezers use 59 percent less, and new freezers use 55 percent less. Similarly, wet accessories like dishwashers and abrasion machines absorb 39 percent and 32 percent beneath power, respectively, than they did in the 1990s.
US appliances, while absolutely added able than they were in the 1990s, cannot bout these gains. Activity Star certified refrigerators, for example, abandoned accept to be 15 percent added able than non-qualified models or 20 percent added able than models that artlessly accommodated the federal minimum activity ability standard. As the DoE's National Renewable Activity Lab credibility out:
Extensive abstruse analyses accept approved the ample activity accumulation that aftereffect from the standards, abnormally in afterwards years as bazaar assimilation increases. An American Council for an Energy-Efficient Economy (ACEEE) abstraction estimates agnate savings. Over the 1990-2000 period, net present allowances beat costs by an over three to one ratio. In 2010, absolute standards will save 250 billion kWh (6.5% of projected electricity use) and abate aiguille appeal by 7.6% (ACEEE 2009).
A 2003 abstraction (Meyers et al.) suggests that standards demography aftereffect from 1988-2003 will abduction accumulative reductions in activity use from 1988-2050 of 8%-9% about to a no-standards baseline. The agnate accumulative costs of these standards accept been estimated to be $200-$250 actor (2002 dollars), with a accumulative (through 2050) benefit/cost arrangement of 2.75:1 (Meyers et al. 2003).
A added contempo abstraction corroborates these findings, ciphering 4% and 8% activity reductions consistent from standards in the bartering and residential sectors, respectively, for standards in abode from 1987-2006 (Meyers et al. 2008).
That said, Activity Star accessories can still advance to added electricity acceptance according to the NREL:
One criticism of these types of labeling programs, both for the allusive advice and ENERGY STAR endorsement, is their focus on ability rather than absolute consumption. Articles are absolute by class, acceptance large, upscale, arduous articles to be a abstracted class from agnate articles with abundant abate activity footprints. This enables products, such as refrigerators, to abound abundant beyond and action added arduous appearance afterwards accident energy-efficiency endorsements. A smaller, beneath arduous artefact can be labeled inefficient application the aforementioned activity burning per cubic aggregate metric. Some evaluations of labeling programs accept cited the charge for a cap on absolute activity burning of articles labeled as activity able (Deumling 2008).
The UK's accelerated strides in accretion its activity ability is abundantly due to a concerted civic push. While US efforts are primarily the aftereffect of accompaniment legislation and bounded annual programs, the UK's advancing civic Energy Ability Strategy has helped the country abate its primary activity burning for the endure seven afterwards years. What's more, the UK government is aswell accommodating in a bounded EU accomplishment to abate activity use by 20 percent by 2020.
These advancing accomplish accept no American equivalent. And in one accurate case, it's artlessly because cipher agitated to ask.
Look No Further Than Your TV

Half of all Americans—roughly 160 actor of us—use a set-top box from either the cable aggregation or a unified TiVo equivalent. And for those of us that aswell use a standalone DVR, which can absorb up to 40 percent added ability than the cable box they're affiliated to, the brace can blot down as abundant as 446 kilowatt hours a year. That's 10 percent added than a 21-cubic-foot energy-efficient refrigerator, or about $3 billion in electricity per year according to the Natural Resources Defense Council.
These accessories are such activity hogs because, clashing their European versions which bead into beddy-bye approach (cutting burning by 50 percent) or dawdling approach (reducing their draw by 95 percent), American set top boxes are consistently on, active at abounding ability 24/7. And as the NRDC abstraction found, these accessories are abandoned active—either broadcasting feeds or recording shows—some 33 percent of the day. The added 66 percent of they're just sitting there, boring hiking your electricity bill. Nationwide, these accessories decay added activity than it takes to ability the absolute accompaniment of Maryland for a year.
This always-on accompaniment is in actuality marketed as a affection by abounding cable companies a agency of ensuring that admirers will be able to instantly alpha watching the moment they about-face on the TV rather than delay 45 abnormal for the programming adviser to load.
"People in the activity ability association anguish a lot about these boxes, back they will accomplish it added difficult to lower home activity use," John Wilson, a above affiliate of the California Activity Commission who is now with the San Francisco-based Activity Foundation, told the NY Times. "Companies say it can't be done or it's too expensive. But in my experience, neither one is true. It can be done, and it generally doesn't bulk much, if anything."
However, to date, abandoned 5 cable/satellite providers accommodate Activity Star adjustable set-top boxes in the US, and only in specific markets: AT&T in Birmingham AL, DirecTV in El Segundo CA, Dish Network in Englewood CO, EPB in Chattanooga TN, and Suddenlink Communications in St Louis.
Of course, there is actual little coercion from government regulators like the EPA to beset cable companies and internet providers to apply these energy-saving functions. Instead, the best we get is a autonomous affairs wherein cable companies can become Activity Star "partners" if they advancement amid 25 and 50 percent of their boxes to Activity Star certified equipment. Granted, an Activity Star cable box will consume, on average, 45 percent beneath activity than non-qualified alternatives, but their bound accessible acutely curtails the program's effectiveness.
What's more, these companies accept been apathetic to embrace the added acrimonious Activity Star requirements—which alone from 138 kWh to 97 in September 2012 and afresh to 29 kWh in 2013—or even awning the Activity Star characterization on able boxes.
"The affair of accepting added able accessories is of absorption to us," Justin Venech, a agent for Time Warner Cable told the NYT. But, "when we acquirement the equipment, functionality and bulk are the primary considerations."
Apparently, even advertence activity ability is anathema if it agency dabbling the burning delight that we've been conditioned to apprehend from televisions. In fact, as Wilson told the Times, if he was still on the CEC he would generally ask manufacturers why the accessories never powered down. Their response: "Nobody asked us to use less." Which is absolutely the akin of action we accept appear to apprehend from such monopolies.
The Backlash Effect
It's not just the ability of our accessories and altitude ascendancy systems that's accretion American home activity use. The admeasurement of our homes and the arduous bulk of accessories we backpack into them accept an aftereffect as well. It's accepted as the Backlash Effect.
Energy ability assets are abandoned able in abbreviation activity burning and carbon emissions if appeal for activity casework abide static. Problem is, this doesn't generally happen, with bread-and-butter assets commonly outpacing those acquired from ability improvements. By abbreviation the bulk of activity bare to run, these casework become almost beneath expensive, which increases the appeal for them, thereby adverse the accumulation from the added efficiency.

For example, while Activity Star-compliant A/C units are now commonplace, their activity accumulation don't awning the actuality that their acceptance has angled back 1980. And while stoves and refrigerators are now added efficient, they're now generally accompanied by a ample arrival of added microwaves, dishwashers, clothes washers and dryers, assorted computers and TV sets, gaming systems, and DVRs—not to acknowledgment the assembly of adaptable accessories aggressive for amplitude on your ability strips. It's little admiration why these accessories now aggregate added than 33 percent of our home electricity use.
Even the activity accumulation acquired from new architecture methods aren't abundant to accumulate clip with bread-and-butter growth. Homes congenital afterwards the year 2000 annual for 14 percent of the US apartment market, according to a contempo Residential Activity Burning Survey conducted by the EIA. Admitting getting 30 percent beyond than earlier homes, they absorb almost 2 percent added than their predecessors. That's some absorbing savings—except that a lot of of the ability access comes from bargain amplitude heating costs (21 percent beneath than earlier homes), due to a majority of these new homes getting congenital in the warmer South rather than our arctic tundras.
What's more, these new homes generally appear outfitted with all the accouterment of avant-garde comfort, advice to an 18 percent activity burning access back 2009 for appliances, electronics, and lighting, than that of earlier homes. The backlash aftereffect is accordingly estimated at about 30 percent for new homes—that is, the added acceptance of a added able technology agency that it will abandoned save 70 percent of what is estimated by engineering models—though the aftereffect can ambit from 5 to 80 percent for specific situations.

America's decidedly susceptible; affective into bigger and bigger houses has been captivated up as the American Dream back at atomic the Hoover administration. As Americans accretion wealth, we move into bigger houses and ample them with added stuff. And cipher is traveling to let the new neighbors see them blind their clothes on a band like a abuse agnostic if there's a cast new clothes dryer to do the job. And if that fancy-pants A/C arrangement is so abundant added efficient, why wouldn't you run it 24/7?
So yes, while added activity ability is actual all-important to abbreviation America's carbon brand and our contributions to all-around warming, it can't be the abandoned answer. Because, as the American humans accept shown, authoritative casework almost beneath big-ticket to run abandoned encourages us to run them more.
