Continue reading Northeast Biodiesel Groundbreaking August 3, Greenfield, MADear Co-op Power Members and Supporters,
Join us Tues., Aug 3rd, 11 am, for the Grand Groundbreaking for Northeast Biodiesel at our land in the Greenfield [MA] Industrial Park – Silvio Conte Drive (at the end of the road near the Coke plant).
After five years of development, everything has finally aligned so that we can build our recycled vegetable oil biodiesel plant and make a clean fuel alternative to diesel fuel that can be used in any diesel engine or oil heat system.

On June 26, at the Cambridge, MA YWCA Emergency Family Shelter, about 30 people from Home Energy Efficiency Team (HEET)
Continue reading Weatherization Barnraising ResultsReduced the leakiness of the building by 12% (reducing the air leakage by 1,500 cubic feet per minute as tested by a pre and post blower door test. Each 100 cfm reduction = 7 therms of gas savings. Thus saving $1,480 for them over the next decade in heating.)
Installed 20 cfls [compact fluorescent lights] (saving probably $11 per year on each one because of the high occupancy of the building)
Installed 3 incandescent exit signs with LED retrofit kits (saving 36 watts per bulb 24 hours a day all year long. Since there were 2 bulbs in each of the 3 signs this will save over $388 in total per year)
Installed 7 low flow showerheads (each saving $42 each in heating the water and $26 in water and sewer charges) $476
Installed 2 programmable thermostats which can save up to 10% on heating if used to turn the temperature down during the winter when no one is home or everyone is sleeping.
We did other work too, but we should save the shelter at least $14,260 in total in energy bills over the next decade.
Thanks for all your work.
Methane (CH4) is a much more effective greenhouse gas than CO2. Methane is also fuel, natural gas. Methane can be made from animal and human dung as well as other kinds of waste.
In Nepal, it is known as Gobar Gas:
“Gobar” is the Nepali word for cow dung. The “Gas” refers to biogas derived from the natural decay of dung, other waste products, and any biomass. In Nepal, villagers use buffalo, cow, human, and other waste products for biogas production. Pig and chicken dung are used in some places, as are raw kitchen wastes, including rotted vegetation….
The Nepalese government built nearly 200 small biogas plants in 1975/6, but decentralized methane digestion truly took off in 1992 when the Dutch group, SNV, launched a large program, including subsidy mechanisms and microfinance schemes, which led to the installation of approximately 204,000 units to date.
Michael Yon wonders if this could also work in Afghanistan.

Thomas Bjelkeman Pettersson on the global swadeshi ning is working on a “flat-pack emergency home” which includes most of what you need for a functional emergency (or camping) home.
Continue reading Global Swadeshi: Flat-Pack Emergency HomeWe intend to actually put together a working demonstration and show that this can be done for under a couple of hundred dollars/euros.
The demonstration will most likely include the following:
Housing / shelter
Hexayurt – our favorite emergency shelter system
Water purification
Siphon filter – an in production unit, costs around $10, made in India.
ChlorinationLight and power
Nova S201 – solar light and mobile phone charger
Sunday, Jun 13th, 12:30-5:00 pm
Last call, we still need at least 20 people!

1. Consistently demonstrate practical, affordable energy efficiency and renewable energy ideas, devices, and systems at the over 4000 weekly farmers’ markets that take place across the USA from Memorial Day to Halloween or Thanksgiving.
The people who attend farmers’ markets are a core constituency for green technology and practical applications that save money, energy, and resources. They are likely to be early adopters who can spread those possibilities into the community. I’ve done energy demos at my local farmers’ market and know that a renewable energy company sometimes participates in the year-long weekly market near Providence, RI. I wouldn’t be surprised if there were more examples out there.
Do energy education weekly at as many of those 4000 weekly markets as possible and over one growing season energy use and attitudes would change significantly. See Mr Franklin’s Folks for one vision of how this might work.

At the NESEA Building Energy Conference in March, the winner of the MA Zero Net Energy House contest was announced. It is the Stephens/Clarke Residence in Montague, MA which was built by Bick Corsa. The 1152 square foot, 3 bedroom house cost $180,000, was monitored from January 1, 2009 to January 1, 2010, and produced two and a half times the energy it consumed. This Zero Net Energy House is actually a Positive Net Energy House.
The house is highly insulated, with R42 walls, R100 ceiling, and stands on an R30 insulated slab. It is powered by 4.94 kW of solar electric panels, solar air and hot water heaters, and passive solar heat gained through U-.17 windows (about R 5.8, according to my calculations). There is a mini-split air source heat pump serving as a furnace and demand hot water heaters as back-up in case it’s needed.
The house used 1,959 kilowatts for the entire year with an annual energy bill for heating, cooling, hot water, cooking, appliances, and lighting of $392. They sold 2,933 kilowatt hours worth $586 back to the grid over that same period.

It was a small group with plenty of time for questions. It turned out that among the other people there were Scott Rasmussen, the pollster, generally assumed to lean Right, Ernest Istook, the former Republican Congressman and present Heritage Foundation and Harvard Kennedy School fellow, and Roger Porter, Kennedy School prof and former Reagan and GHW Bush official (I’m always amazed at how liberal Harvard is).
Broder had a few introductory remarks about the differences between the Clinton attempt at reforming health care and the Obama success. He credited Rahm Emmanuel with understanding Congress much better than Ira Magaziner did and pointed out that Obama made his push in his first year, with all his political capital intact, while Clinton began his health care initiative in his second year.
Then he took questions.

Continue reading Green Building CourseDo you want to know more about green building? Do you know a student who might want to earn college credit to learn about green building?
My name is Ryan Harb. For those of you who don’t know me, I’m a finishing graduate student from UMass and in May I will become the first person in the country to receive a MS in Green Building. I have a strong interest in ecological design and for 4 years I have been transforming my single-family home in Amherst, a college rental property, into a model sustainable residence. One project I’m working on now is a front yard transformation – creating a 5000 s.f. highly productive, food producing, permaculture garden at my home. Designing sustainable (food and other) systems is one of many aspects of green building.
This summer I will be co-teaching a 3-week Sustainable Design and Construction course at Sirius Community in Shutesbury, MA – a model educational and sustainable ecovillage in scenic western Massachusetts. This is one of the few opportunities in the country to receive college credit while learning experientially about sustainable design and construction. All students will receive natural building certification upon completion of this course.
