Big-screen televisions make a power play

Oct 26 - McClatchy-Tribune Regional News - Rick Montgomery The Kansas City
Star, Mo.

We all scream for flat screens, even in a flat economy.

But the bigger picture, many say, is one of unnecessary stress on the
nation's electricity supply for years to come.

In a culture that resists carbon-emitting power plants but covets the
latest gadgetry -- high-speed here, high-def there and knowing "there's an
app for that" -- well, there's also an electric bill for that.

Televisions, in a sizzling comeback, are leading the pixilated pack
and stirring the most concern among energy conservationists. California is
even poised to require that new models be more efficient.

Since 2000, "we've seen energy consumption from TVs jump from 3
percent (of residential electric use) to 8 percent and climbing," said Adam
Gottlieb of the California Energy Commission.

"If we sat on our hands and did nothing ... we would need to build a
$615 million power plant" just to feed all of the state's hungry flat-panels
by 2020.

Sales of TV sets are through the roof, where the antenna used to be.

"Here we are in a terrible economic time and the demand for TVs of all
kinds has grown incredibly," said Tamaryn Pratt of Quixel Research, which
tracks market trends.

Experts attribute much of the surge -- an estimated 35 million digital
sets shipped to dealers this year, up from 25 million in 2007-- to plunging
prices and the nation's recent switch to digital broadcasting.

Even as polls show television audiences moving to computers for
entertainment, Nielsen numbers show Americans with more working TVs than
ever before (roughly 3 sets per home now, compared with 2.1 in 1990).

And those sets are switched on 8 1/2 hours a day per household, an
hour longer than a decade ago.

connected to the TVs.

Big screens, big bills

HD sets are becoming more energy efficient each year, the industry
notes. But because newer models are sleeker and many pounds lighter than
those bulky analog TVs of old, much larger screens are now practical and
popular -- and that's where most of the energy burns.

Depending on the size and brightness of the screen -- and, of course,
the amount of use -- a flat-panel TV hooked to a cable or satellite box,
plus a digital recorder, eats 5 to 10 percent of a home's electricity,
studies show.

When the sets are on, their energy thirst rivals that of some
refrigerators.

The product review site Cnet.com lists some 65-inch plasma screens
soaking up more than $150 worth of power in a year, although the energy
costs of smaller HDTVs are typically less than $60.

Add to your new HDTV other innovations of the digital age -- your
laptop, Xbox, iPod and cell phone charger.

Now stir in the "phantom load" of 1 to 5 watts simmering all day
through remote-operated devices. All of this gadgetry combined can guzzle 15
percent of your household power, according to the International Energy
Agency.

It's not that a liquid crystal display -- or LCD, the most popular of
the newer TVs -- hogs more energy than an analog picture tube of similar
screen size. But because flat panels are so versatile, larger screens (dinky
ones, too) can easily be placed on walls, desktops and StairMasters
anywhere.

"In health clubs, bars, airports, hotel hallways," even above restroom
urinals, Gottlieb said.

To avoid building that extra coal-fired plant, he said, California has
drafted first-in-the-nation mandates for energy efficiency in TVs. The
energy commission is expected to pass the regulations next month.

The aim is for all but the largest screens sold in the state to meet
standards similar to those encouraged by the Environmental Protection
Agency's Energy Star program, which is voluntary. By 2013, Gottlieb said,
the rules will save enough power to electrify "864,000 single-family homes,
year after year."

In the 1990s, federal regulations on refrigerators and other large
appliances echoed efforts first undertaken in California. Energy-cutting
advocates credit the rules for making today's refrigerators 45 percent more
efficient.

Manufacturers have lobbied hard to keep Washington from enacting
mandates on home electronics -- TVs, personal computers and battery
chargers. President Barack Obama pledges to look into setting some rules.

Jennifer Bemisderfer of the Consumer Electronics Association said
government tinkering would only stifle innovation and undercut "the
flexibility that's needed for a fast-moving industry. ... Regulations just
can't keep up."

Some experts question how much effect the latest products have on
efforts to conserve electricity and curb greenhouse gases.

A typical laptop computer, when churning, uses about 40 watts --
1/100th the power of a running clothes dryer.

And even when a 42-inch TV is illuminating the room at 250 watts,
"it's like having a few extra light bulbs on," said Michael Bluejay, who
goes by "Mr. Electricity" on his Saving Electricity Web site.

Much of the extra juice needed to power our high-tech stuff is offset
by savings we've reaped from increasingly efficient washers, air
conditioners and windows, Bluejay noted.

"Before you obsess about TV consumption in your home, you should
obsess about the heating, cooling and lighting."

College conservation

The Kansas City Star found evidence of his point on some college
campuses -- fertile ground for the latest in consumer electronics.

"Just when you upgrade a building's efficiencies for lighting, here
come more gadgets" that require juicing, said University of Kansas housing
director Diana Robertson.

Then she dug through electric bills for McCollum Hall, which houses
900 students, to check usage going back 12 years.

To her surprise, the power load last spring semester was a few hundred
thousand kilowatt-hours under 1997 levels.

Did weather make the difference? Or was it all those energy-efficient
light bulbs, one fixture at a time?

Lots of students, come to think of it, did trade their 300-watt rack
stereo systems for small iPods and earbuds.

At the University of Missouri-Kansas City, officials reported similar
energy reductions, however slight, in the last 10 years at a residence hall.
Same at the Columbia campus.

Laura Lutz, a conservation accountant for Westar Energy, speculated
that big screens in college common areas may actually benefit the
environment. Like public buses, they serve crowds of students, who otherwise
would tune in alone in their rooms.

As for the meter dials of Westar customers, electricity use last year,
per household, was up a mere 2 percent from 1998 levels.

"What I'd like to think," Lutz said, "is the prevalence of information
out there on how to save energy has made a difference."

HOW TO REDUCE THE JUICE

Here are some ways to cut back on the electricity powering your
favorite stuff:

--Use power strips that you can click off to stop the "phantom"
current flowing into your devices.

--Disconnect chargers as soon as your cell phones and MP3 players are
juiced up.

--Wait before you replace that TV. They'll be more efficient in two
years. Some will even have sensors that turn off the set when nobody is in
the room.

--Reduce the brightness on your screens. HDTVs are commonly set to
"vivid" in the stores. You can live with "standard" in your den.

--Set your computer to "sleep" when not in use.
