VoIP, PoE & Power Use
"PoE for VoIP is just the first step; you're going to be powering more devices," noted Gary Audin, president of Delphi Inc., who has written extensively on power related to VoIP.
As more and more companies turn to LAN switches to power their VoIP deployments with PoE, Audin said, a good number fail to ensure that the wiring closet and data centers are ready to handle increased power consumption. In some cases, new wall sockets are required in order to power the switches that run PoE. In extreme cases, Audin said, an enterprise may have to rely on its utility company to run more power to the building itself.
Audin estimates that on a simple per-phone basis, running VoIP requires roughly 30% to 40% more power than old TDM phones. Running more equipment in the closet is also going to increase the amount of heat generated, requiring additional cooling, which in turn sucks up more power.

Copper 5 - Global in '06
International Copper Study Group (ICSG) data indicate
that the global refined copper market for the first 11
months of 2006 had an apparent production surplus of
about 108,000 t. This compares with a production
deficit of 263,000 t for the same period in 2005.
Reported stocks at the end of November of 955,000 t
were up by 104,000 t from those at yearend 2005, yet
remained well below the 1.78 Mt held at the end of
2003.
Owing to production disruptions in the first part
of the year, global mine production for the first 11
months of 2006 was essentially unchanged compared
with that in the same period of 2005. Total world
refined production, however, increased by 5.1% in the
first 11 months of 2006 compared with that of the same
period of 2005.
World refined usage increased by
about 2.6% compared with usage in the same period of
2005 (International Copper Study Group, 2007).
Again, these figures include guesses about what's going on in China. That does not necessarily make these numbers "wrong" (or valueless). But the surprises that keep happening in the copper market (in terms of price) are almost certainly attributable to fluctuations (whether stage-managed or caused by need) in Chinese buying and selling.

Copper 4 - '06 Prices
Copper prices continued their upward trend during the
first 5 months of the year, and in May the COMEX spot
price reached a record-high price of $4.08 per pound,
nearly twice the previous record-high price of $2.28 set
in December 2005.
The refined copper production
deficit that had persisted over the preceding 3 years
resulted in tight supplies, limited stock availability, and
concerns over supply adequacy.
Higher metal prices also led to increased speculative
interest in metal markets.
Prices generally trended downward during the
second half of the year, with the COMEX price
averaging $3.07 per pound in December and $3.15 per
pound for the year, an 81% increase from that in 2005.
Given some of the information contained in Copper 1-2-3 -- above or findable in the March 07 archive -- it's hard to believe that copper prices averaged $3.07/pound in 12/06, isn't it?
28 Mar, 2007
Copper 3 - Consumption '06
U.S. reported consumption of refined copper declined
by 6% to the lowest level in 15 years and was down by
30% from peak consumption in 2000. Shipments by
domestic producers of wire rod declined by 5.8%, and
U.S apparent consumption of wire rod declined by
6.1% from that in 2005 (American Bureau of Metal
Statistics, 2007).
Shipments during the fourth quarter
were particularly week, declining by 23% from those
during the fourth quarter of 2005. The sharp decline
was attributed to the weak housing market and high
copper prices that encouraged destocking along the
entire supply chain.
It's hard to correlate the information presented above with copper prices (which are covered in the next item) and the U.S. economy as a whole. Copper consumption was down 30% from 2000? Wowser!
28 Mar, 2007
Copper 2 - '06 Production
Preliminary production data for the full-year 2006
indicate that U.S. mine production rose by 6%
compared with that in 2005: Production of copper in
concentrate rose by 15% while electrowon production
declined by 4%.
Concentrate output rose following a
return to full production at Asarco’s mines in Arizona,
whose production was reduced by a 16-week strike in
2005; increased output from the Bingham Canyon
Mine in Utah; and startup of concentrate production at
the Morenci Mine in Arizona.
Production of electrowon copper at Phelps Dodge Corp.’s mines in
the United States fell to 459,000 t from 483,000 t in
2005, while their production of copper in concentrate
declined by about 3% to 183,000 t (Phelps Dodge
Corp., 2007). Production of copper in concentrate at
Bingham Canyon rose by 20% to 266,000 t owing to
higher mill throughput and ore grades (Rio Tinto plc,
2007, p. 5). The Lisbon Valley Mine in Utah and the
Phoenix Mine in Arizona reported their first copper
production in 2006.
If I read that correctly, copper production in the U.S. rose by 6% last year. That helps explain the end-of-year decline in copper prices, maybe.

Copper 1 - Consumption Drop
Here's the lead paragraph from the front-page article . . . which otherwise contains a lot of info about specific companies and their pet projects.
The average daily mine production of copper in December
was unchanged from that in November, according to data
compiled by the U.S. Geological Survey. Following the return
to full production in November of two smelters closed for
maintenance, the average daily smelter production in December
rose by 60% to the highest level since October 2005.
Downstream average daily electrolytically refined copper
production rose by 21% compared with that in November.
Consumption of refined copper continued its fourth quarter
downward slide, falling by 8% to its lowest monthly level in 20
years.
I don't know what to make of the fact that refined copper consumption in December hit its lowest monthly level in 20 years. One would thing the price would have fallen heavily.

Yellow Alert
It posted 3/26. There's a lot of seasonally adjusted data in here, but the bottom line is in the bottom table on the page (CLICK HERE to see it) -- this is Year-To-Date Construction Starts -- UNADJUSTED. Figures in the table below are in millions of dollars.
WHAT'S IMPORTANT HERE -- of course, your eye is drawn to the 29% tumble in the value of residential construct contract starts. BUT: What you SHOULD be looking at (the EleBlog take) is the 2-month total in the Nonresidential Building column. It's flat. My guess before going to this page would have been that it would be UP.
Adding together the AIA, NAR + MHC reports, and at the very least we seem to have good reason to merit a caution flag.

Here are two recent data points:
American Institute of Architects -- Architecture Billings Index . . . Drops Five Points.
EleBlog take: Both of the releases have a positive spin, despite the negative "news" embedded in the data they report. I believe the NAR is perhaps the single organization most guilty of liberally applying the wrong "spin" to housing data, and therefore I am suspicious of what the org says; if NAR said the sky was blue, I'd be expecting green.

The Yen Carry Trade
Step 1: Borrow yen at 0.5% and convert the yen into $9,000 US dollars.
Step 2: With $9,000 from Japan and $1,000 of your own money, invest $10,000 in US Treasury notes at 5.00%.
Step 3: Collect $500 in interest from the US Treasury, and pay $45 to the Japanese lender.
Step 4: Pocket the $455 difference as a profit, for a rate of return of 45.5% on your original $1,000.
Step 5: Sell the US Treasury note, and convert the US dollars back into Japanese yen to pay off your loan.

Employment - EC Industry
All-time peak year was '01, with 759,400. So we're not all that far from that!
As I just checked, preliminary data was also available for January 2007. Production worker employment in the EC industry was 708,000, as initially estimated by BLS -- or 4.47%. That's the best January since 2002 (which was on the downstroke side of the 1998-2001 boom), and is (again) exceeded only by the Jan figures for 2000 and 2001.
Peak MONTHLY employment during the boom was 784,100 in September 2000, a figure so high that it caused some people -- well, at least ME -- to say . . . "from where did all of these electricians come?" Hey, I've looked into it since, and they were NOT all electricians.
The monthly peak in 2006 came in August, at 728,100.

Rates Go Nuts In Calif.
I have been encouraged to believe a similar rate schedule exists for Southern California -- with the rate on the highest end @ 51 cents/kWh.
Let's take a look at this. If you reach the highest rate below and you have a 60-watt light bulb and leave it on for 10 1/2 hours over two days, you've just tacked on 39 cents to your bill! If you typically use the bulb for 5.25 hours a day, the cost to operate that bulb (the marginal cost, assuming it's a bulb you turn on after all of your other electricity is in use) is on the order of $6/month.
That's for ONE light bulb.
If you are a true believer in Capitalism, Markets, and such, one tenet of your beliefs must be that Price Transmits Information. What information is being communicated here, with Big Users of electricity (on the residential end) getting shellacked with rates like 39 or 51 cents per kilowatt hour?
As the RenewableEnergyAccess article states, the idea is to push "Energy Hogs" off the grid. See the article here. That seems to be the idea, doesn't it?
| PG&E Schedule E-1-Residential Service | ||
| Tier | Rate | Monthly Usage* |
| Baseline Usage | $0.11430 | 480 kWh |
| 101% - 130% of Baseline | $0.12989 | 481 kWh - 625 kWh |

| 201% - 300% of Baseline | $0.32146 | 961 kWh - 1,440 kWh |

- 1.6% of 2006's U.S. electricity generation came from petroleum-fired plants.
- That total was down by 73.4% in December 2006 from December 2005 (that's a one-month reading).

Nuke Status Report
"There are 435 nuclear reactors in operation world-wide, but most were built in the 1960s and 1970s. Finland last constructed a nuclear plant in the late 1970s, and Areva NP, the Areva-lead joint venture at Olkiluoto [Finland], hasn't been a lead contractor since the 1980s.
"Excluding Olkiluoto, 29 reactors are currently being built, mainly in Asia, but all are using old designs that Western European and U.S. nuclear-safety regulators won't allow."

Hot Market: Wireless-Industrial
"The worldwide market for wireless technology in manufacturing is expected to grow an average 26%/year over the next five years." That will take it from $325.7 million in 2005 to more than $1 billion by 2010.
I know most electrical contractors didn't get into the business after looking at the wide world of opportunities -- most contractors started out as electricians. But you don't have to have an MBA to see that there's opportunity here, especially if you're in an area where manufacturing is still being done. Here's a piece of the rest of the HP article:
"A major factor favoring greater deployment of wireless technologies in manufacturing is the ability of wireless applications to enable new and better ways of operating manufacturing plants Process manufacturing stands to feel the greatest impact. Field operations within a process plant are a classic case of the need for more information that can only be delivered wirelessly
" . . . millions of field devices are installed at great cost in process manufacturing facilities. However, because most are not digitally enabled, their ability to share process and maintenance information is extremely limited. This presents a huge opportunity for wireless technology, which can be used to enable these 'stranded' assets to the benefit of operations, maintenance, and business systems across the enterprise."

GE's Incandescent News (2010)
Here's the slice that interested me, from a GE exec:
"We and other lighting manufacturers have been aggressive in developing and marketing CFLs. But consumers want more options and we plan to respond to their needs and deliver environmental benefits, too. It’s important that we offer consumers a full range of products that meet their personal desire to reduce their negative impact on the environment while preserving their ability to pick the best lighting product for their needs. That’s why we are moving aggressively to commercialize these new lamps."
What I did not see -- in the 18Seconds item on the DOE site (referenced in the previous item) or in the GE release -- is anything about LED lamps. I know for a fact that the first generation of "white" LED lamps for general use will be introduced this year.
At some point, we're going to need a chart that compares the energy efficiency AND the user reception of LEDs, CFLs . . . and now the "HEI incandescent" from GE.

CFLs & '18 Seconds'
The gist: "the 18Seconds movement" is behind replacing an incandescent bulb with a compact fluorescent (CFL). Why the strange name? "It takes only 18 seconds" to change light bulbs (is there a joke in this somewhere? 35 seconds for scientists? 2 hours and 11 minutes for Brittany Spears?).
As it turns out, if you go to 18seconds.org, you end up at http://green.yahoo.com.
I've already noted here (on 2/27 -- to see blog entry, CLICK HERE) that fluorescent lighting is not for everybody. I related my personal experience with trying to replace incandescents with CFLs.
As a spoiler, the DOE item noted that "Now that people are learning that CFLs use far less energy than incandescent light bulbs . . . GE is preparing to throw a wrench in the works." See next item.

Home Tech 'Flattens' Out (???)
Here's a link. I'm not sure it will work for you; you might need to register.
"CEA/NAHB: Install Rates Flatten For Some Segments." NAHB = National Assn. of Home Builders. The two associations surveyed home builders on custom-installed electronic system inclusion in houses -- in the 5th "state of the builder technology market study." Two tables were offered in the publication -- and TWICE slapped a copyright notice on each one of them, so I'm not going to reproduce them here . . . altho I gotta say, putting a copyright on data produced by someone else's survey must require the same chutzpah that Pat Riley (a basketball coach) had when he copyrighted the term, "Three-peat."
[Pat Riley's term as coach of the New York Knickerbockers is the reason that I am no longer a Knicks' fan. And I was present at the famous Games 5 & 7 of the 1970 NBA playoffs!]
- - - - -
OK. To get back to the matter at hand, here's what I can WRITE from the copyrighted data:
Structured Wiring installation was reported at 45% of new homes in 2002 and 61% in 2004, but only 49% in '05 and 53% last year.
Multiroom Audio rose gradually from 9% in '02 to 16% last year. But that means 5 out of every 6 homes leave the builder's loving arms without this service.
All of the other techs named -- Home Theater, AUtomated Lighting Controls, Home Automation, and Energy Management -- were in the 6% to 12% range for 2006.
- - - - -
A separate table showed the # of builders who offer the technology (this is, you know, different from the # of homes!!!).
87% of builders offer structured wiring last year, which makes the 53% number above seem sort of pale. 78% of builders offered it in 2002.
Automated Lighting Controls were the big gainer in the table -- while 31% of builders offered that in 2002, the figure last year was 57%. Energy Management had a similar-sized gain, from 31% of builders saying they offered it five years ago to 52% last year.
- - - - -
According to the TWICE story, "CEA concluded that 1.02 million new homes were outfittined in 2005 with structured wiring, fallikng to 960,000 in 2006. Multiroom audio was installed in 310,000 new homes in 2005 but only 290,000 in 2006. Home theater installs fell from 230,000 in 2005 to 220,000 in 2006." Keep in mind these numbers are NEW homes, not ALL homes.
I'm not sure those numbers are related to what's happening in the real world. They are CEA's effort to match up NAHB new-home building figures with the % numbers in the survey. That's not scientific, really. It's a stab in the dark.

From IES's Conference Call
1. Near the end of the prepared company remarks, CEO Mike Caliel said this:
EleBlog take:
a. The way the info appears in the transcript, it appears to be a non sequitir. That's not terrible, but it is kind of weird.
b. This is a case of a CEO stepping on some significant news. Perhaps it doesn't really matter to Wall Streeters and investors, but the launch of a school-to-work program by the biggest "pure-play" electrical contractor in the U.S. is NEWS to most of the rest of the real world (i.e., big news for the electrical industry, construction industry, and school-to-work universe!).
c. I checked the Web site www.ies-co.com and I can't find a release on the school-to-work thing. The company is hiding its light under a bushel basket, in the old adage.
- - - -
2. Later on, in answer to a question, Caliel talked about the company's efforts to "improve the purchasing of the business," in the analyst/questioner's term:
a. At one time, distributors and manufacturers FEARED the prospect of IES getting its supply-chain effort together. This was in 1999-2000, when IES said it would be a $3 billion (annual sales) company by 2003, and when it was using its prospective size as leverage to knock down the prices it paid. Here we go again! However, this time IES is not prospectively a $3B company. IES will top $1B in sales in the current fiscal year -- but not by very much.
b. In the process of scouring the site to look for the school-to-work release, I found a 3/12 item that announced the hiring of Christopher Haas, 41, a refugee from CSX Transportation, as the veep of supply chain management at IES.
c. Earlier in the call, Caliel -- who hails from Invensys, by the way -- said the company was focusing initially on things like fuel purchases and vehicles in its supply efforts. But, clearly, it will get to wire and cable!

China Power
Along with financial info and credit-market news you won't find anyplace else (at least not for FREE), Noland -- a person I do not know, by the way -- provides a roundup of key news you might otherwise miss. A sample is this quote from a 2/7 Bloomberg news item:
"China, the world's biggest energy user after the U.S>, plans to increase power generating capacity by 15% this year to meet rising demand . . . the nation will add 95 gigawatts of capacity by the end of 2007 . . . the nation had a 4th straight year of power shortage(s) last year, when consumption peaked in summer. The nation's total installed capacity increased by 20% in 2006 to 622 gigawatts."
OK -- so China added more than 100 gW in 2006 and is going to add another 95 mW this year. That means from 2005 to 2007, the Middle Kingdom will have gone from around 515 gW to 715 gW. WOW!
Hey - 95 gW = 95,000 megawatts. That's 95 power plants of 1,000 mW each, which is a big power station. This is impressive! But it's also depressing, if you think "man" causes global warming . . . as much of China's power is generated via the use of Coal.

Tony Guzzi, president/COO --
"We like data centers because they're heavy users of mechanical and electrical systems and life safety systems that need to be installed to exact tolerances, and typically they are fast-track projects. They are truly mission-critical facilities with mission-critical systems.
"Our scope for the USDA will include general lighting, power, redundant switch gear, UPS, remote distribution panels, battery pbackup, a 15 kW generator set, fire alarm, security, and telecommunication systems."
I guess Guzzi's comments best explain why data centers are a focus of The EleBlog.

DC Lessons Learned
NwC is supposed to run stories about data centers, so it's no biggie, I guess. But here's the article's lead paragraph: "By next year, fully half of today's data centers will have insufficient power and cooling capacity to support high-density equipment, according to Gartner Predictions. We believe it, based on our own recent tests of the blade servers that are rapidly altering our computing infrastructures and changing how we deal with spiraling heat and power consumption."
While I've read the article, I didn't segregate sections to see how much of it was about Electrical stuff. I would say that, based on my initial reading and a quick scan just now, this article is MOSTLY about electrical and structured cabling considerations for state-of-the-art data center construction.

Cool Air in India + China
The gist is in the subhed: "Demand exploding in India, China for air conditioners that use chemicals being banned here."
Some sample quotes:
- From a resident of Mumbai -- "All my friends have air conditioners now. Ten years ago, no one did."
- In China, ownership soared to 87.2 air conditioners per 100 urban households in September [2006], from 24.4 seven years earlier." This does not take into account that country's huge non-urban population!
- "China . . . is stepping up exports to the United States of air conditioners using [HCFC-22]." Note that production of this substance is banned in most industrial countries by 2020. The U.S. has banned domestic production as of 2010.
- Net-net: "The emissions of things like HCFC-22 -- we had thought they were sufficiently in control," according to a scientist. WRONG.

Market for Protective Relays
- On a worldwide
basis, the annual market for medium and high voltage protective
relaying products and equipment currently exceeds the $1.5 billion
dollar level as we move further into the 21st century. Only a portion
of the total market for protective relays is made up of the world’s
electric utilities directly, with significant indirect sales made to
industrial companies, to OEM suppliers that integrate relays into other
equipment used by utilities and industrial/commercial end-users, and to
independent power producers.
- There are currently at least six suppliers of protective
relays and ancillary equipment that each enjoy a minimum of $125
million in sales into the global market (ABB, Areva T&D, GE,
Nanjing Automation Research Institute, Schweitzer Engineering Labs, and
Siemens). The Spanish firms Arteche and ZIV, the French firms Schneider
and CEE, the Finnish firm Vaasa, as well as the UK division of the
Eaton Electrical organization, are among the important “second-tier”
suppliers based in Europe, with strong export potential. Their
counterparts in North America include Basler, Beckwith, Cooper Power
and NxtPhase, among others. In Asia, four Chinese manufacturers
(including NARI, NAEF, Henan Xuji and Beijing Sifang) are now among the
larger relay suppliers globally, and each is growing based on the huge
and growing “home market” for protection and control of the expanding
Chinese electric power grid. These are joined by some well-established
Japanese relay manufacturers.
- The American firm, Schweitzer Engineering Labs, remains as one of the fast growing companies in the worldwide protective relay industry through year-end 2006, although the company’s growth rate has declined from earlier levels as their installed base and revenues have grown. The company’s global market presence and expanded array of relay-based offerings continue strong into 2007.

No Laughing Matter. But . . .
My attention was diverted from this (while reading about it) by the following headline on a 2/26 Associated Press wire item: ""Downtown blasts bad for business, Waterbury merchants say."
No kidding.
Reading into the piece, there was a quote from a local guy: "People who come downtown may soon start saying, 'Look, there's a manhole. Am I going to get clobbered?'"
Here's the name of the guy quoted (and I really am NOT making this up): Ken Killer.

Guide to DCs
I can answer that, of course. But my answer is going to be something about "because they are important!"
You don't have to agree. But if you need to get "up to speed" on data centers now, or in the future, you might try the Executive Guide to Data Centers, posted (or updated) on Feb. 1. Get to it by clicking here.

You Ain't Green If . . .
I'm not kidding. The Internet is the ultimate Energy Hog. According to an article in Network World (2/15) -- click here to see it -- "U.S. data centers account for 1.2% of the country's electricity consumption."
OK, the Internet is a blessing. It makes us more productive, business-wise and personally. But you have to consider that electricity is NOT very efficient. Generally speaking, the amount of useful energy you suck out of a receptacle is equal to about 35% of what the power company put in (it's a long story, but trust me).
Another factolito from the story: "Energy consumption in corporate data centers doubled between 2000 and 2005."
And another: A research firm, IDC, forecasts that "worldwide server energy consumption will increase 40% between 2005 and 2010" . . . and it could actually be higher.

Electricity Rates in CA
Here are the problems with that:
b. So I thought I misheard the guy. 10-11-12 cents per kilowatt hour, sure. But 51 cents? That means if you leave a 100-watt light bulb on for 10 hours, your bill goes up 51 cents. You could well do that 30 times in a month. Operating a 100-watt light bulb could cost you 15 bucks???
c. My conclusion, then, was that I had to look for a hearing aid.
I'm not kidding.
However, earlier this past week, I ran across an article on RenewableEnergyAccess.com -- "Solar for Energy Hogs." It's a controversial article (and might make interesting reading), but that's not why I'm referencing it (and linking to it).
Page down to the table on that page. Accoridng to the rate listing (for nothern California this time), if you use "200% of baseline" as a residential electric consumer in northern California, you'll be billed 32 cents per kWh. If you hit the 300%+ level, you'll pay 37 cents/kwh.
NOW, I'm pretty certain I don't need a hearing aid. OK, that's not the main point here. The point is that some people in California may well end up paying unreal rates for their electricity.

Long Shot Odds
OK -- so this isn't directly relevant to electrical contractors. But it sure as heck IS relevant to HVAC contractors, people who breathe (100% of us, I would think) . . . and especially to me. In 2000, I came very close to death, thanks to the goddamn Legionella bacteria. I went on a vacation in Spain and came back to the U.S. with Legionnaire's Disease.
According to the article, "European Union estimates of incidence vary from 1 to 20 cases per million people . . . the true number of cases may be 20 times greater than this figure, since only a small fraction of cases are reported to public health authorities."
20 x 20 is 400 out of 1 million on the high end. A given human's chances of inhaling the bacteria and become deathly ill (i.e., what happened to me) are 4/100ths of 1%, then. And that a shaky number. They could be half that, or less.
That's as far as the article goes on numbers; from there, it progresses to discuss why people who operate ventilation systems might pay attention to this disease.
For me, the net result was both horrible and very positive. I spent 25 days in the hospital. On 13 of those days, the doctors and nurses used every trick they knew to bring my body temperature down but -- according to my wife -- it varied between 102 and 104 degrees (F). When they finally brought my temp down, they thought there might have been some brain damage (actually there was, but it was very minor).
Many people who get this disease die. Others lose major portions of their lung capacity. My pulmonogist told me of a patient who retained only 30% of his lung capacity; he was too weak to come to the doctor's office, the doctor said, so the doctor actually made house calls to see him (think about that!). I retained 100% of my lung capacity. So after coming in like a 125-to-1 long shot with the damn disease, I came through with flying colors.
If you're reading this and you own a building, think about having your air-handling system looked at -- regularly -- by professionals. You don't want to be guilty of killing people with the air you provide.
