10 Questions for . . . Jon Strimling, President of WoodPellets.com

In this installment of 10 Questions for . . ., Associate Editor Gian Trotta speaks with Jon Strimling, president of WoodPellets.com about the pellet market. Strimling also addresses some of our readers' concerns about wood pellets and their delivery.

Jon Strimling WoodPelletsLast year there were reports of pellet shortages. What are the prospects for pellet supplies this winter?
We're clearly in a better position now at the macro level than we were last year, when oil prices shot through the roof in May, June, and July and caused a run on pellet supplies. The industry usually has until November to provide enough fuel for a winter season, but last year many people saw prices going up and thought that they should get their pellets early.

The sudden surge in demand was challenging, and there were times last year when one coast or another would go into back order. But the country has never been short of supply; it was just a case of the product sitting in the wrong place. We were able to keep a flow, but pellets were traveling farther and cost of transport was higher.

A fair bit of additional capacity has also become available. Over past few years 20 new mills have started producing pellets in U.S. and Canada, and new capacity has been added to existing plants. This year, a major boost to raw-material supplies consists of lodgepole pines in Colorado and British Columbia. Because of beetle infestations in recent years, there is an enormous quality of dead standing timber being removed for forest-fire mitigation, and the highest-value use of that resource is pellets.

Will all those factors offset the reduction in pellet raw materials from lumber and wood-flooring production?
Certainly, housing starts are down, and that has reduced capacity of some mills that rely on that stream of dry residual wood. But most of the newer mills can employ "green chips" that enable them to continue to produce premium pellets, and in some cases even superpremium pellets. These clean, debarked chips are cut before wood is dried, for example from the lumber cut from side of logs to square them.

How vulnerable are pellet-producing plants to supply interruptions?
Fortunately, production is dispersed among several areas and companies to reduce chance of shortages. Individual pellet-supply facilities can go down, especially if they are linked to a particular lumber mill. The network of 80 to 100 plants is as a whole pretty robust, so if someone goes down, someone else will pick up that volume.

One of our readers noted that when he began using pellets five years ago, pellets were $110 a ton, now he's paying $265. What is your long-term forecast for pellet prices?

It may be that this consumer got a very unusual deal in 2005 through some sort of a clearance event, because that price is much lower than even typical wholesale pricing was in 2005. If you look at when we started this business in 2006, our retail price was right about what it is now. In 2008, pricing went up about 10 percent.

If you go back five to 10 years ago when crude was cheaper, pellets cost less. Wood and pellets are typically moved by trucks that use diesel fuel, which has gone up since then; so there's no avoiding that pellet prices will rise as oil rises, as diesel fuel is an element of pellets' cost. Normally, when the price of oil doubles, it results in an increase in transportation costs for pellets of about 25 percent.

How do sales of pellet-burning appliances affect your demand forecast?
Last year, sales of pellet-burning appliances were up 180 percent. We won't see sales like that repeat this year—probably not until the next spike in oil pricing. But every heating system sold creates an incremental increase in demand, and people who have systems are continuing to use them, even with oil at lower price levels.

What we're seeing this year is that demand for pellets is coming later. There hasn't been mad rush to go out and buy supply, so we're seeing a later buying season with strong demand. There's not a feeling of panic of everyone this year like last year with the continued growth in the industry. Folks with stoves and inserts are telling friends to go out and buy a pellet-burning stove.

What's the difference between premium and superpremium pellets?

The Pellet Fuel Institute just released a new standard for superpremium pellets and is working out the statistical data around the new methodology. Ash level is a major distinction. Premium has a maximum of 1 percent ash content while superpremium has less than one-half of one percent. That's a big deal to a stove owner because you're cleaning your stove half as often.

Other things tested by the PFI include Btu content, length and diameter of the pellets, and durability. The heating value and ash level are of primary interest to a consumer. The range of variation for the heating value can be 10 percent, but ash level can vary by a factor of three. Moisture level is inversely proportional to heating performance also.

At opening of Florida solar-energy facility, President Obama focuses on smart grid and renewable energy

President Obama DeSoto Next Generation Solar Energy CenterOn Tuesday, President Barack Obama promoted the smart grid and renewable energy at the opening of Florida Power & Light's DeSoto Next Generation Solar Energy Center (shown). The facility consists of more than 90,500 solar panels, making it the largest solar-photovoltaic plant in the country and, according to FPL, its annual estimated generation is about 42,000 megawatt hours.

The president outlined how the federal government is making a $3.4 billion investment from Recovery Act funds to modernize the country's electric grid with a goal of creating a more-reliable, more-efficient system. "But getting there will take a few more days like this one and more projects like this one," said the president. "And I have often said that the creation of such an economy is going to require nothing less than the sustained effort of an entire nation—an all-hands-on-deck approach similar to the mobilization that preceded World War II or the Apollo Project."

If you're interested in using solar power at your home, read our report on solar water heaters from the October 2009 issue of Consumer Reports and look for ongoing coverage of these devices on this blog, such as this testing update from earlier this month.—Daniel DiClerico | | Twitter | Forums | Facebook

Essential information:
The president referred to World War II the other day, and it was during this era that George Löf undertook his first experiments with solar power. Löf, a solar innovator who died earlier this month at the age of 95, is credited with creating one of the earliest solar-heated homes in this country, according to his obituary in The Wall Street Journal. Löf's system consisted of a large glass roof panel that heated a pile of gravel in the basement, which in turn warmed the house.

Latest news on Chinese drywall

Chinese Drywall Investigation CPSC"This is a complicated problem, and we have several studies and other activities underway to help bring the best possible science to bear. The first sets of data released today start to explain differences between Chinese and non-Chinese drywall, but more remains to be learned. We are sharing what we know at this point and are outlining the next steps as we continue to work to answer homeowners' questions about what is causing the effects reported and observed."
 
That's how the U.S. Consumer Product Safety Commission, in a press statement released yesterday in conjunction with the U.S. Environmental Protection Agency, the U.S. Department of Housing and Urban Development, the Centers for Disease Control and Prevention, and the Agency for Toxic Substance and Disease Registry, described its ongoing investigation into Chinese drywall.
 
On its Drywall Information Center, the CPSC says it has received almost 1,900 reports from people in 30 states, Puerto Rico, and Washington, D.C., "who believe their health symptoms or the corrosion of certain metal components in their homes are related to the presence of drywall produced in China." (In the photo, the small gray section directly under the thumb is drywall removed from a home.)

Weekend Project: Weatherize your attic to save money and boost comfort at home year-round

Properly weatherizing your attic can cut 10 to 30 percent off your heating and cooling bills, according to the U.S. Department of Energy. And while you might not want to spend the money (or the time) to do the work, keep in mind that the federal government offers a 30 percent tax credit up to a maximum of $1,500 on weatherization materials, and utilities and states in place like Massachusetts, New York, and Washington offer additional incentives that sometimes cover labor costs.

There are some simple things to remember when weatherizing your attic, such as never using duct tape on, well, ducts. Also know that if some conditions are present, such as if your insulation is wet or there's mold or knob-and-tube wiring, you should hire a contractor to do the work.

Otherwise follow this advice from the DOE's do-it-yourself guide to attic insulation (PDF) and our own Complete Guide to Reducing Energy Costs to seal up your attic and start saving money now. Download this PDF from the book for more details on insulating your attic and/or basement: Insulate Basement-Attic, and watch our video.


1. If you see dirty insulation . . .

It means air is passing through the insulation from the heated space below because most thermal-insulation products are not air barriers. Search for the source of airflow, such as a large open chase or smaller gaps around an electrical wire or junction box or plumbing pipes or vents

2. If you see narrow gaps less than 1/2 inch wide . . .
Seal gaps with the appropriate caulking. If the crack is deep, use flexible backer rod before caulking. (Gaps around heating-system flues, chimneys, or recessed lights should be handled differently to avoid a fire hazards; see the precautions below.)

3. If you see gaps more than 1/2 to 2 inches wide . . .
First, close up large openings using scrap wood or metal flashing that you screw in place. Then caulk all seams and small gaps or seal using expandable, spray-in water- or foam-based sealant. Remember, foam-based sealants can expand to several times their original volume, crush flexible vent pipes, and cause structural damage if too much is applied. Water-based foams expand less; you can also use fiberglass insulation stuffed in a plastic bag. When working, wear gloves, long sleeves, and a dust mask specifically marked as being for fiberglass insulation. And remember, foam-based sealant is also nearly impossible to remove if you get it on your skin, and fiberglass insulation can irritate skin.

4. If you see uninsulated areas around light fixtures or where chimneys and furnace flues penetrate through floors . . .
Most recessed light fixtures that protrude up into the attic should not be covered with insulation, which could cause them to overheat. Instead, use a similar barrier made of sheet metal, wire mesh, or lumber to keep the insulation away from the light housing. These fixtures also allow air to flow, but unfortunately most cannot be sealed directly. You can build a larger box enclosure around each fixture that can serve as the air barrier, or you can have the fixtures replaced with a version that is an air barrier type rated for insulation contact as well.

For chimneys or flue pipes, use a heat-resistant caulking or follow the DOE's instructions to create a sheet-metal insulation dam that will keep insulation 2 inches away from the heat source.

5. If you see joist edges showing above your current attic insulation . . .

Add another layer of roll insulation perpendicular to the joists. Use a piece of scrap wood to push the first line into place under the eaves but don't block airflow from the eave out into the attic space. While the attic floor surface should be insulated, an air gap should exist between the roof rafters so air can flow between the eave and the rest of the attic. Don't use foil-faced insulation. The layer of insulation below should have an existing vapor barrier.

In general, good building practice requires three barriers of protection on the surface that separates the heated and cooled living space of the rooms below and the unconditioned attic space above. These barriers are the thermal insulation to slow the heat loss (or gain), the air barrier to stop uncontrolled air exchange between the two spaces, and the vapor barrier to prevent moisture migration. Typically, the vapor barrier should be on the warm side of this dividing surface, so in a warm climate it would be on the attic side of the thermal insulation, and in a cold climate it would be on the living space side of the thermal insulation. The air and vapor barrier can be provided by one product or separate products or approaches.

Detroit house to be turned into giant ice cube

Ice Dams Detroit Ice House ProjectYou might have heard about or even had to deal with ice dams, those frozen build-ups around the eaves of a home that can damage roofing and siding during winter (see illustration). In Detroit, two artists are taking the concept of the ice dam to the extreme, and perhaps that's appropriate in a city known as Hockeytown, USA.

Architectural photographer Gregory Holm and architect Matthew Radune plan to encase one of Detroit's thousands of abandoned homes in ice this winter, according to this Associated Press report. Through their Ice House Detroit project, Radune and Holm want to draw attention to the staggering number of foreclosures in the city.

(Michigan saw the eighth most foreclosure activity in the third quarter of 2009, says RealtyTrac. And according to the latest Standard & Poor's/Case-Shiller Home Price Index, the August 2009 price index in Detroit is at 71.59,which is the lowest of the 20 cities tracked and 22.6 percent lower than it was a year earlier.)

Holm and Radune plan to spray the house with water until it is gradually covered with ice. Come spring, after the ice has melted, the house will be demolished after crews salvage building materials.

Is this a cool concept or a cold-hearted gesture exploiting a recession-ravaged city? Leave a comment below.—Gian Trotta | | Twitter | Forums | Facebook

Shale gas holds promise, but drilling for it is controversial

As we covered in Buzzword: Shale gas, this natural gas contained within fine-grained, sedimentary rock is a topic of much interest for the energy industry. There are vast reserves of shale gas nationwide, and energy companies are working hard and fast to tap these natural-gas sources through what's called water fracturing, also known as hydraulic fracturing or hydrofracking. (The graphic below details how hydrofracking works. It was created by Al Granberg and is being used courtesy of ProPublica: Journalism in the Public Interest, a site that features lots of coverage of shale gas and gas drilling.)

As you might expect, there's more to shale gas than the promise of abundant supplies of natural gas and lower prices for consumers. There's also concern that the process used to tap into the shale-gas reserves presents serious environmental and health risks.

Today's New York Times features an interesting story, "Gas Company Won't Drill in New York Watershed," on the decision by Chesapeake Energy not to drill for natural gas in upstate New York after the Oklahoma City-based corporation's plans met with strong opposition. If you're interested in the topic of shale gas, give it a read.—Steven H. Saltzman | | Twitter | Forums | Facebook

Want to start a debate? Bring up the subject of drying laundry on clotheslines

Line Drying Clotheslines Right to DryHealth-care reform is an important and hotly debated national issue these days. While certainly not as pressing as health care, the subject of hanging laundry out to dry is something many people seem just as passionate about.

Consider the comments to our June 2009 post "Are Clotheslines Making a Comeback? 'Right-to-Dry Movement' Promotes Their Use" and those in response to The New York Times' recent engaging online debate "Rethinking Laundry in the 21st Century."

Right-to-dry-ers tout clotheslines and the like as tried-and-true energy savers that leave laundry smelling great. Some folks are skeptical about the practice, wondering whether line drying will leave their clothes feeling crunchy and questioning the added time it might take to dry their laundry. Those opposed to clotheslines feel they muck up their neighborhoods.

According to the U.S. Department of Energy, the average American household uses about 11,000 kilowatt hours of electricity annually, with the typical electric clothes dryer consuming about 900 kWh—around what the average washing machine uses and slightly less than a typical refrigerator does.

If you're not ready to dry your laundry on a clothesline or on racks, follow these steps to cut back on dryer-related energy use:
• Use an automatic cycle for drying. This cycle will call on the dryer's moisture sensor, which automatically turns off the machine when the laundry is done. The sensor will work even if you select the less or more dry option.
• Remove the lint from the filter after every load. Built-up lint can reduce air circulation and make your dryer run longer. What's more, lint can clog the dryer vent, where it poses a significant fire hazard.
• Dry lightweight laundry in one load and heavier items, like towels and jeans, in another.—Kimberly Janeway | | Twitter | Forums | Facebook

Inside Consumer Reports Test Labs: Which vacuums make pet-hair cleanup less of a nightmare?

Consumer Reports Pet Hair Pickup VacuumsThe menacing-looking device in the photo (right) isn't a prop from Saw VI or some gruesome Halloween slasher film, though it could play a part in Nightmare in Yonkers: Pet-Hair Perils. The photo is actually a shot of John McAloon, a project leader in our Technical department, holding a new device he and his team created to embed pet hair into the carpeting we use for vacuum testing.

About three years ago, we instituted pet-hair testing, having recognized that so many readers were looking for the best vacuums to deal with their dogs' and cats' (furry) droppings. We decided to use hair from Maine coon cats because it's especially long and provides a rigorous test for the dozens of vacuums we review each year.

We're always looking for ways to improve and enhance our testing. In this case, we're experimenting with a different way to embed it into the carpet.

That’s where the rolling rake above might come into action. Basically a row of washer and spacers attached to a handle, the rake weighs more than 19 pounds, heavy enough to create furrows that are more representative of how pet hair works its way into the carpet fibers in your home. The vacuum testers simply roll the rake back and forth over the pet hair they’ve laid down. 

If you don't own a cat or dog or other furry creature, you might not care so much about pet hair. But as anyone with a shedding animal can tell you—including folks on our vacuum forums—removing hair from carpeting or furniture can be a real nightmare.—Ed Perratore | | Twitter | Forums | Facebook

By the Numbers: S&P/Case-Shiller U.S. National Home Price Index continues upward trend

146.00

S and P Case Shiller Home Price IndexCurrent level of the 20-City Composite Home Price Index, part of the Standard & Poor's/Case-Shiller U.S. National Home Price Index, which tracks residential prices in housing markets nationwide. The August 2009 level marks four consecutive months of improved readings and is up 1.2 percent from July, although it is still down 11.3 percent from it was a year ago. The index is calculated monthly and published with a two-month lag.

"While many of the markets remain down versus this time last year, the relative rate of decline has shown some real improvement," said David M. Blitzer, chairman of the Index Committee at Standard & Poor's, in today's press release. "California, in particular, has seen some real positive prints in recent months." The price index in San Francisco climbed 2.8 percent from July to August, behind only Minneapolis, which saw an increase of 3.2 percent. Charlotte, Cleveland, and Las Vegas were the only three markets whose price index fell from July to August.

The rise in the 20-City Composite Home Price Index comes at a time when the overall economy is expected to show 3.5 percent growth in the third quarter. But, said Blitzer, "We do want to remind people of the upcoming expiration of the federal first-time buyer's tax credit in November and anticipated higher unemployment rates through year end. Both may have a dampening effect on home prices."—Daniel DiClerico | | Twitter | Forums | Facebook
