Mawna, Bangladesh
Here in the Bangladesh countryside, amid the emerald-green rice paddies and farmers threshing crops with their bare feet, are beige cows, giant haystacks… and solar energy panels – 200,000 of them scattered throughout the country.
This clean-electricity source is part of an innovative program conducted by Grameen Shakti, the environmental arm of Grameen Bank, which won a Nobel Peace Prize for its pioneering use of microloans in Bangladesh.
Its projects also include biogas production, improved cookstove technology, and solar power training centers for women.
Grameen Shakti (meaning “village energy” in Bangla) was started in 1996 as a way to bring electricity and better living standards to the country’s rural poor. “At that time, 85 percent [of the total population of 140 million] had no electricity,” says Dipal Barua, the nonprofit group’s managing director.
He’s speaking from his 19th floor office, which is lined with solar panel prototypes and overlooks the country’s capital, Dhaka.
When Grameen Shakti began, about 120 million people in the country didn’t have access to a source of electricity, he says. Most were poor rural residents living in primitive conditions. By providing electricity to them, the organization hoped it would also help increase education rates and economic opportunities.
Now, 13 years after the program’s inception, its efforts reach almost 2 million people in every part of Bangladesh.
Grameen Shakti first focused on solar panels because, as Dr. Barua notes, “Bangladesh has plenty of sunshine.”
And not only are solar panels portable, they are also better for the environment and more reliable than the nation’s present energy grid, which is not only unavailable to most areas outside cities but also prone to frequent blackouts.
Traditionally, most rural dwellers rely on kerosene or candles as energy sources. But they’re costly, give negligible light, and emit fumes.
Following the model popularized by the Grameen Bank, Grameen Shakti used microcredit loans for disseminating the panels. Buyers make down payments of 15 to 25 percent and then pay off the loans in two or three years.
The cost of the panels is offset by the buyers’ lower energy costs. For example, explains Barua, shop owners who purchase a solar panel system no longer have to buy candles in order to stay open at night. Previously, a shopkeeper might have spent $6.50 a month on candles, but for a small solar panel system with a battery, the monthly payment is about half that. And in addition, the solar unit would allow the store to stay open longer, generating more income.
Mawna, a rural village several hours north of Dhaka in the Gazipur region, is a model of Grameen Shakti’s success. Farmers like Mrs. Abdul Kalev can return home after a day of work, turn on the lights, and relax in front of a TV set powered by an 85-watt solar panel perched on the roof.
Kalev says that her six-person household enjoys its new energy source immensely. They’re pleased because it has improved their lives and also helps the environment. Now that they have reliable electricity, the children can study in the evening and don’t have to breathe kerosene fumes.
“Grameen Shakti’s innovative approach is not only providing families in the developing world with clean, regular energy sources,” says Katherine Miller, United Nations Foundation communications director, “it is helping strengthen local communities and providing economic opportunities.”
“Eventually we thought [about] how to maintain the [solar panel] system,” says Barua. And the group wanted to “involve the poor women also.” They realized that when women improve their lives, the whole family benefits.
One issue about the maintenance of the solar panels was that in this Muslim society, and especially in the conservative rural areas, women are home alone during the day and aren’t allowed to let in male technicians unless a male family member is present.
However, having female technicians would automatically eliminate this issue, they realized. So women’s engineering technology centers were created.
Now women like Champa Akter, who works at the engineering technology center in Mawna, learn to assemble home solar systems and also how to install and maintain them.
The technicians live on-site at the regional offices and go out into the field to provide service as needed. So far, the program has set up 20 centers and trained more than 1,000 female technicians.
Down a dirt road in Mawna and behind a large chicken coop of 2,000 egg-laying, red-feathered hens is Mrs. Mohammad Abdur Razzak’s underground biogas plant. It’s another project initiated by Grameen Shakti. The organization realized that individual farmers usually keep two to three cows or chickens, and wanted to help them set up small-scale biogas plants to use the livestock’s waste to their advantage.
Razzak hoses her poultry coop’s waste into the connected chamber, where it ferments and creates biogas, which is released into a pipe that’s connected to her cooking stove.
Since Razzak’s animals produce more gas than she uses, she makes an extra $71 per month by renting 10 cookstoves and the excess gas to her neighbors.
The leftover slurry that isn’t converted into gas is sold to local farmers for use as organic fertilizer.
A 2006 World Bank study found that rural women and children under the age of 5 had the most exposure to indoor pollution from wood-burning cookstoves. To help alleviate this, Grameen Shakti designed a more fuel-efficient stove that produces less smoke and costs less to use.
It burns half the wood of a traditional stove, the smoke is funneled away from the cooking area via a pipe, and the ashes can be used as fertilizer. “It’s very environmentally friendly,” says Barua.
Inspired by Grameen Shakti, the UN Foundation “helped finance a project in India that makes solar power affordable for more than 1,000 families” in 2006, Miller says. “We are also currently working on expanding portable, clean-energy cookstove programs across Africa.”
But can this be a successful model in more urban areas, where energy needs are greater? There is cautious optimism.
“If rural areas are successful in having expanded the generation capacity of renewable energy [and] solar energy,” says Quamrul Islam Chowdhury, chairman of the Forum of Environmental Journalists of Bangladesh, “then it can be replicated in [Bangladesh’s] cities in a gradual manner. If it can be supplied and be guaranteed, then people will go for it.”

Entangled Bank
by Little (
Entangled Bank is a mixed-use plan with residential and retail aspects. It was designed to include a sky pasture to sustain livestock. The building has community garden areas and is powered by vertical axis wind turbines and photovoltaic panels. Glass ponds capture rainwater and provide irrigation for the extensive vertical farm and green roof system. Entangled Bank will have 500 residential units, an Organic Farming Institute, and a Slow Food Restaurant.
Greenways Xero Energy
by David Baker + Partners and Fletcher Studio (San Francisco, CA)
Greenways Xero Energy takes its shape from an abstract, beached naval ship in order to capture solar exposure and rainwater. The design features community gardens, vertical farming, solar thermal energy, and photovoltaics. Shading on the south side of the structure reduces cooling loads and geothermal tubes negotiate temperature swings. Dallasites may notice that this design, particularly with the red touches and box cutouts, plays off the design of

There is growing interest in using crop residues as the feedstock of choice for the production of cellulosic-based ethanol because of the more favorable energy output relative to grain-based ethanol. This would also help provide a solution to the debate of food versus fuel, because less of the grain would be diverted to ethanol production, leaving more available for food and feed consumption.
Crop residues are viewed as a low cost and readily available source of material since more than 50% of crop production is residues. However, crop residues should not be considered simply a waste or benign material. They possess a critical role in sustaining soil organic matter. Consequently, extensive removal of crop residues for ethanol production—or for other industrial purposes—may impact the long-term productivity of soils.
Agriculture and Agri-Food Canada scientists at the Indian Head Research Farm in Indian Head and the Semiarid Prairie Agricultural Research Centre in Swift Current, all located in Saskatchewan (SK), measured the impact of straw removal after 50 years on soil organic carbon (SOC) and soil organic nitrogen (SON) using the Indian Head Long-Term Rotations established in 1958. These rotations included a series of fallow–spring wheat–spring wheat crop sequences where straw was removed through baling on selected plots. In this study, straw removal with baling occurred 2 years out of 3, or 66% of the time. The study was converted to no-till in 1991.
Another 4-year study was conducted to quantify how much wheat straw is actually removed through baling when different harvesting systems are used. The three harvesting/straw removal systems involved (1) swathing-harvesting-baling, (2) straight harvesting-baling, and (3) harvesting with a stripper header-swathing-baling. Both of these studies were funded by Agriculture and Agri-Food Canada, the Panel on Energy Reduction and Development, and the Indian Head Agricultural Research Foundation.
Results from these studies were published in the Agronomy Journal by G.P. Lafond and others. The results were also presented at the annual meetings of the Indian Head Agricultural Research Foundation held in Moose Jaw, SK, on 27 Jan. 2009 and the Saskatchewan Soils and Crops Workshop on 26 Feb. 2009 in Saskatoon, SK.
Guy Lafond, who was the study leader, says, “The results would support the recommendation that some straw could be removed from fields providing that the frequency of removal was less than 66% and that no more than 40% of the aboveground residues other than grain are removed. From a crop management perspective, proper nitrogen fertility combined with no-till would further reduce the possibility of net losses in SOC and SON.”
Research is ongoing at Agriculture and Agri-Food Canada to examine different types of crops for not only their grain and end-use quality but also for their crop residue production and quality. Some crops are being developed as platforms for biomass production.

Green roof by-law with overwhelming support yesterday. The green roof by-law consists of a green roof construction standard and a mandatory requirement for green roofs on all classes of new buildings. The by-law requires up to 50% green roof coverage on multi-unit residential dwellings over six stories, schools, non-profit housing, and commercial and industrial buildings. Larger residential projects require greater green roof coverage, ranging anywhere from 20-50% of the roof area.

We at Greencon feel this is the lead (exscuse the pun) local governement should be making to get Green Building Built:
Officials in Portland, Ore. have proposed a green building incentive program that would be the first of its kind in the United States. Under the program, new commercial buildings, 20,000 square feet or larger, that meet Oregons state building code would be assessed a fee by the city of up to $3.46 per square foot. The fee would be waived for buildings that achieve the Leadership in Energy and Environmental Design (LEED) Silver certification from the U.S. Green Building Council (USGBC). Those that achieve LEED Gold, LEED Platinum or the Living Building Challenge, would receive rebates of $1.73-$ 17.30 per square foot depending on certification level.
Based on the same requirements, multifamily residential properties, 5,000 square feet or larger, would also be eligible for rebates of $0.51-$5.15 per square foot. Multifamily projects, 50,000 square feet or larger, that receive city funding must meet LEED Silver standards.
For new single-family residential construction, the proposed program sets performance targets for the percentage of homes certified through either LEED for Homes or Earth Advantage. These targets increase from 20 percent in 2009 to 40 percent in 2011. If the targets aren't met at any point, the city of Portland will set up a feebate structure similar to that used for commercial buildings.

A new consumer label that would grade all commercial buildings according to their energy efficiency is being developed by the American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE).
Known for its development of commercial building code standards, the society's label would measure both the design efficiency and operational performance of buildings, similar to the government's Energy Star program. ASHRAE said it would eventually like to expand the label to include property types not covered by Energy Star. If that effort is successful, ASHRE indicated it would push for an international expansion.
