Elementary school tests heating technology novel to Interior Alaska

From The Fairbanks Daily News-Miner, Friday, September 17, 2010:

Large rolls of black tubing sat like super-sized balls of yarn next to the playground outside Weller Elementary School Wednesday. The sun shined brightly on the south-facing hillside, where a bulldozer carved out a 12-foot hole.

The balls, which are actually polyethylene ground loops, were then rolled out and buried in the ditch, where they will harvest heat from underground to use in the school during the winter. In the summer, six solar thermal panels soon to be mounted on the school will replenish heat to the earth through the same tubes. The system will not only reap savings on heat for the school district but also will test a technology that is young in Fairbanks.

“I would like to see a system that would work well in the Interior and that the public can utilize and save dollars,” said Larry Morris, projects manager for the Fairbanks North Star Borough School District.

The project is an experiment to see how well the systems work in tandem and to collect data on ground source heat pumps, which are common in the Lower 48 but rare in Fairbanks.

“What we’re trying to do here is pair that system with a solar system that will recharge the heat you take out of the ground. In warmer climates, the sun can recharge how much you take out,” said Aaron Sirois, an engineer for PDC Engineering. “We were trying to come up with a solution that’s kind of adapted to Fairbanks.”

Wind power company in 'talks' with AVEC

From The Tundra Drums, Wednesday, September 15, 2010:

WindPower Innovations Inc., a wind power infrastructure and smart grid solutions company (PINK SHEETS:WPNV), announced talks with Alaska Villages Electric Co-op (AVEC), a non-profit electric utility, owned by the people served in 53 villages throughout interior and western Alaska, and is the largest service area of any retail electric cooperative in the world.

News of the talks arrived in a written statement from WindPower.

“We are in the second round of talks with AVEC to enhance the efficiency of their 250-500 kW wind turbines with our system optimization and grid-tie solutions,” says John Myers, president and CEO of WindPower Innovations. “Alaska represents a marketplace in the hundreds of millions and soon to be over a billion dollars for wind and other alternative energy sources, and the adaptability of WindPower Innovations’ technology allows us to capitalize on opportunities in extreme and remote environments where others can’t. We will be able to provide AVEC with solutions that help them break through barriers in efficiency and help solve the challenges faced by Alaska’s extremes in climate, geography and distance.”

AVEC is in the process of upgrading and increasing the operating efficiency of its power plant facilities and distribution lines, along with expanding its wind power segment, continuing to move away from costly diesel-generated power.

Parnell signals support for large-scale hydro option

From The Fairbanks Daily News-Miner, Saturday, September 11, 2010:

Gov. Sean Parnell says that if Alaska is to meet the ambitious goal of getting half of its electricity from renewable sources some day, it will have to make a major commitment to big hydroelectric project, such as the Susitna project.

On a visit to Fairbanks today with running mate Mead Treadwell, Parnell said that he is putting a group together to see how a major hydro project could be financed. He said he wants to send a “strong signal” of his support of hydro power as a long-range option.

He also is looking for answers on ways to reduce the cost.

The Legislature and the governor approved $10 million earlier this year to update studies on Susitna and the proposed Chakachamna project.

The state now has an official policy that it will be getting 50 percent of its power from renewable sources by 2025, according to a law approved by the Legislature and governor earlier this year.

It may be impossible to reach that target in 15 years. It will be impossible unless decisions are made soon to get something underway.

Alaska getting $700,000 for energy efficiency

From The Associated Press, Friday, September 10, 2010:

The federal government is giving Alaska $700,000 to take steps to improve energy efficiency in the state by 2020.

The U.S. Department of Energy funding is intended to go toward efforts such as expanding current energy efficiency programs and outreach and creating necessary policy to lead to a 15-percent improvement in efficiency over the next decade.

The department says this is part of nearly $30 million going to 12 states and territories.

LED Lamps Go Where Compact Fluorescents Cannot

From The New York Times, Wednesday, September 8, 2010:

Mention “new lighting technology” and what leaps to mind is probably a compact fluorescent curlicue. Shaped like a soft ice cream cone, it is viewed as a replacement for the ubiquitous 60-watt incandescent light bulb, which looks almost like it did 90 years ago.

But a profusion of light-emitting-diode lamps is about to hit the market, many of them in applications that are awkward or impossible for compact fluorescents.

LED’s are still mostly specialty items sold on the Web. But by the end of this month, the 2,200 Home Depot stores around the United States will stock seven types, including two substitutes for the classic incandescent bulb, one of which my colleague Leslie Kaufman reported on recently.

But those are “not the most compelling use” of LED technology, according to Zachary S. Gibler, chief executive of the Lighting Science Group Corporation, which makes the lamps that Home Depot will stock. Replacing a standard 60-watt bulb, an LED will produce roughly the same amount of light per watt of electricity as a compact fluorescent; its only advantages, he said, is that it is fully dimmable and lasts a lot longer.

Another product his company is marketing is something most consumers can identify, but not name: a round lamp with a face about the size of a silver dollar, with a base consisting of two metal pins, often used for accent lighting in kitchens or retail stores. Called an MR16, it is almost always halogen, which is only slightly more efficient than a standard incandescent. It is much too small to allow for a fluorescent version.

But Lighting Science is selling an LED version. Installed over my kitchen sink, it casts a much whiter light than the yellowish halogen it replaced. It can take a bit of getting used to, but vegetables in the sink seem truer in its light. A 6-watt version can replace a 35-watt halogen, which is a consideration if it’s the light you leave on all night.

Fall harvest teaches horticulture for a cause for Fairbanks students

From The Fairbanks Daily News-Miner, Wednesday, September 8, 2010:

The entrance of the garden at the Tanana Valley fairgrounds smelled like a minty fusion as about a dozen students harvested crops Tuesday afternoon.

“The spearmint needs to be weighed. The kale needs to be weighed,” said Sheryl Meirerotto, who teaches the eighth-grade class from Effie Kokrine that was busy digging, plucking and weighing vegetables.

The class will prepare a portion of the produce for a potlatch dinner during the Alaska Federation of Natives Convention in October.

The garden, which has existed for many years and has been managed by the University of Alaska Fairbanks for the last two years, demonstrates how much can be grown in the Interior.

“The purpose of the garden is to represent the crops grown in the Tanana Valley. People don’t know we can grow things like corn,” said Jeff Werner, a UAF researcher and Alaska Future Farmers of America adviser.

State works with villages to keep them warm

From Alaska Dispatch, Tuesday, September 7, 2010:

A state program designed to ensure that rural Alaska communities have an adequate supply of home-heating fuel is headed into its second successful year, the state reported in a press release.

The Fuel Watch program is an initiative of Gov. Sean Parnell that was implemented by the Department of Commerce, Community and Economic Development through its Division of Community and Regional Affairs.

Fuel Watch came about as a proactive approach to preventing the kind of seasonal hardship that fuel shortages caused in many rural communities in the winter and early spring of 2009.

To date, DCRA staff have made hundreds of phone calls to communities around the state to verify that fuel supplies are in order for the upcoming winter. In the program’s first year, DCRA staff made more than 1,500 phone calls and assisted 200 communities prior to the onset of winter. Alaska villages saw a significantly reduced number of fuel shortages than were experienced a year earlier.

“Fuel Watch is an excellent example of the proactive and supportive relationship our department strives to develop with communities throughout Alaska. Working to prevent another crisis situation is a much better use of state resources than responding to an actual crisis,” said Susan Bell, commissioner of the Department of Commerce, Community and Economic Development. “Alaskans will be better prepared this winter because of the dedication of Division of Community and Regional Affairs staff.”

DCRA officials are also working with fuel delivery companies and rural communities to identify where assistance may be needed. Communities with limited financial resources are being encouraged to apply for financing through state loan programs.

“Ensuring that rural families stay warm in the winter is part of our division’s mission to promote healthy and safe communities,” said DCRA Director Tara Jollie. “It is not too early to start thinking about the coming winter. When we take steps to avoid an emergency, it is a win-win situation for everyone involved.”

Fairbanks Rescue Mission’s Recycling Center celebrates anniversary

From The Fairbanks Daily News-Miner, Saturday, September 4, 2010:

The Fairbanks Rescue Mission celebrates the first anniversary of its recycling center today with a barbecue and open house starting at noon.

Executive director Rodney Gaskins will be available to guide things along. Visitors might get to check out the baler that compacts the cardboard, mixed papers and aluminum the center receives. One bale of cardboard can weigh 800 pounds, while a bale of mixed paper can weigh about 1,700 pounds.

“It’s a mark of success,” Gaskins said of reaching the one-year mark.

The center surpassed its millionth pound of recycled materials in July and expects to hit 1.5 million pounds by the end of this month. The recycled paper is sent to Anchorage to become insulation, and the aluminum stays in Fairbanks where it’s sold to C&R Pipe and Steel Inc.

So far, the program is paying for itself. “A nonprofit is mission-driven,” he said, “we’re successful whether we’re making money or not.”

The plan was for the Rescue Mission to take baby steps at least until it had one year under its belt. Now he believes the recycling center can take the next big step.

“We really wanted to start small,” Gaskins said.

As he put it: “Don’t start a restaurant until you have the capability of managing a hot dog stand really well.”

The center plans to expand in the near future by adding plastics to the list of materials that can be recycled but that can’t now because of insufficient storage space.

“For us, it means that we have been able to build a sustainable recycle program,” said John Lofquist, who works at the center. “It’s allowed Fairbanks to have a recycle option.”

The center will operate at its regular hours during today’s celebration; it will be open to the public from 11 a.m. to 5 p.m.

Clean energy can lessen Native suffering

From The Anchorage Daily News, Sunday, August 15, 2010:

As an Alaska Native veteran, I want to see our country expand our clean energy sources. It will help our planet and our state, it will help Alaska’s Native peoples and it will help our national defense.

I am 69 years old. In my lifetime I have seen many changes connected to global warming. A big part of where I grew up has permafrost. The small village where my mother was born has sunk in and is now part of a large lake. I saw the old village of Kasigluk begin sinking in my short lifetime. The island where my maternal grandparents lived is mostly gone. A new Kasigluk was created almost a mile downriver from the old village. A new school, federally funded houses, post office and airport had to be built at a high cost.

The warming has affected the fall white fish runs on the Johnson River not far from Bethel. People there rarely fish for them anymore. The black fish creeks are almost nonexistent because of the changing river channels due to warming. The Yukon-Kuskokwim Delta has been invaded by beaver, which dam up the many small tundra creeks, disrupting the black fish runs.

Newtok, where my maternal grandmother’s family is from, and the village of Shishmaref need to be relocated at great cost due to erosion. Our elders link the erosion to changing weather due to warming. The melting of the permafrost also increases the cost of constructing homes and public buildings.

In rural villages, the cost of fuel to heat homes is high. So is the cost of electricity, which comes from expensive diesel fuel.
