The fossil fuel divestment movement is making progress here in the Commonwealth. Earlier this year, the House has passed HB 4354, a bill that creates a committee to assess whether a divestment plan for the state’s pension systems is feasible. The bill is now in the Senate Ways & Means Committee. On November 17th, the Boston City Council weighed in in favor of divestment, passing a resolution urging the Massachusetts legislature to take action before year’s end to begin divesting state retirement funds. The City Council resolution, sponsored by Councilors Matt O’Malley and Michelle Wu, passed by an 11 to 1 vote.
In sharp contrast to our local and state politicians, federal officials come off rather poorly in a new report by DeSmogBlog and Republic Report about the revolving door between government -- including the Obama administration -- and the fossil fuel industry. The report exposes efforts by the fossil fuel industry to gain government support for exporting fracked natural gas. The report details the efforts of former government officials lobbying on behalf of the fossil fuel industry. The industry has repeatedly claimed that fracked natural gas is intended for the domestic market. Though the climate and the environment will suffer no matter who burns the gas, the industry has garnered support for fracking by claiming that it will lower US energy costs and reduce US reliance on foreign oil.

Solar rooftop map gives you all the numbers
By Eric Smalley
The Boston Solar Map just got a lot more useful. The site has had a high-tech makeover and can give you a detailed estimate for installing a rooftop solar electric system for pretty much any home in the city. Give it a try here: www.mapdwell.com/en/boston. Type in an address – or click on a rooftop on the map – and you’ll be able to see all the numbers, including how many trees worth of carbon you’ll be saving by putting solar on your roof and how long it will take you to break even.
The estimates include carbon offset (in CO2 tons, trees, 60-Watt lightbulb days, air conditioning hours, driving miles and flying miles), cost to owner, years until payback, and a detailed breakdown of credits and revenue. The Boston Solar Map was made by Mapdwell LLC, which licensed the underlying technology from MIT. In addition to Boston, Mapdwell has solar system maps for Cambridge, Wellfleet, Washington DC and Washington County, Oregon.The Boston Solar Map assumes an installed system cost of $5.33 per watt. The map uses a sophisticated model to determine the amount of sunlight that hits each roof. Here’s the company’s description:
The tool uses high-resolution (1- by 1-meter grid) Light Detection and Ranging (LiDAR) data to create a three-dimensional model of the sample terrain that accounts for the shape of building rooftops and structures, existing infrastructure, and tree foliage. The model is later used as the base for evaluating the amount of solar irradiation that falls on each unit of surface – for every single hour of a typical year – and determining its individual potential for solar electric generation using photovoltaic (PV) panels.Mapdwell says that its technology has been validated to a 5 percent margin of error.
Take a look at your house on the map, then consider making it happen. Take the next step here: www.nextstepliving.com/partners/rozziesolar.

Residents say no to West Roxbury pipeline
By Eric Smalley
On the eve of a primary election, more than 100 people turned out for a public meeting at the Dedham Holiday Inn last night held by the Federal Energy Regulatory Commission (FERC) to hear comments about a natural gas pipeline slated to run from Westwood through Dedham into the heart of West Roxbury. The proposed route places the pipelines adjacent to an active quarry that does blasting about three times a week and has heavy truck traffic.
The meeting was called to comment on FERC’s draft environmental impact statement for the planned expansion of Spectra Energy’s Algonquin Gas Transmission natural gas pipeline. The expansion would increase the capacity of the pipeline, which runs from New Jersey to Beverly. The project includes a new, 5-mile spur into West Roxbury.
A near universal concern was the lack of notice for the meeting and for an earlier informational session held by Spectra Energy. Many, including City Councilor Matt O’Malley, State Rep. Ed Coppinger, and representatives for Mayor Marty Walsh and City Counselor Michelle Wu, called for a second meeting. Despite the short notice and proximity to the election, more people turned out than the meeting’s organizers anticipated. Hotel staff put out an additional 30 chairs shortly after the meeting started.
Twenty-seven people spoke, two in favor of the pipeline and the rest expressing concern. Many voiced vigorous opposition. Here’s an audio recording of the hour-and-a-half comment session.
Here’s a sampling of the comments:
Several residents who live near the quarry said they were concerned about having a natural gas pipeline so close to such powerful explosions. “I live about two blocks from the quarry and when they blast in the quarry my whole house shakes like there’s been an explosion in the basement,” said Catherine Arnold, a Boston public school teacher.
Edward Doyle, a retired engineer and Dedham resident, noted that the environmental impact statement doesn’t include a list of structures that would be within 300 feet of the pipeline. “If there’s going to be a pipeline coming into Boston, it shouldn’t be through these high residential areas,” he said.
Doyle also referred to the San Bruno, California gas explosion and 1,000-foot fireball that killed eight people 4 years ago today. The pressure in that pipeline was 386 PSI. The pressure in the proposed West Roxbury pipeline would be 750 PSI.
Judy Kolligian of the Boston Climate Action Network noted that there are 4,000 gas leaks in National Grid’s distribution network in Boston and said that we should get a handle on fixing these before a new pipeline is built.
Several speakers expressed concern that the project could enable more fracking and gas export. And many speakers cited the threats to public health, the environment and the climate. “The cost estimates cited don’t include the health costs, the risk of worsening climate change, the loss of habitat and the deforestation,” said Susan Bergman, a physician from Framingham.
FERC is accepting additional comments until September 29. There are two ways to comment, either through FERC’s eFile system (follow the eFile link on the top right of the Draft Environmental Impact Statement information page) or by printing out this form and mailing it in.

West Roxbury pipeline: health, safety and climate at risk
Source: Spectra Energy
By Eric Smalley
Please take advantage of a rare chance to comment on a natural gas pipeline expansion near our neighborhood. The Federal Energy Regulatory Commission (FERC) is holding a public comment meeting in our area about the capacity expansion of Spectra Energy’s Algonquin Gas Transmission natural gas pipeline. The expansion includes a new, 5-mile spur into West Roxbury.
The public comment period on FERC’s Draft Environmental Impact Statement (PDF) for the project ends September 29. You can comment either in person at the meeting or online using FERC’s eFile system (follow the eFile link on the top right of the Draft Environmental Impact Statement information page).
The meeting is Monday, September 8, at 6:30 PM at the Holiday Inn Dedham, 55 Ariadne Road, Dedham, MA 02026.
Here’s some background on the pipeline and its expansion:
The Algonquin Gas Transmission pipeline begins in New Jersey, where it connects to the Texas Eastern Pipeline, which brings natural gas from Texas to the northeast. The pipeline ends in Beverly, where it connects to the Maritimes & Northeast Pipeline, which runs from Nova Scotia through Maine and New Hampshire. The Beverly facility also connects to a Liquefied Natural Gas (LNG) port 10 miles offshore.
The stated purpose of the expansion, labeled Algonquin Incremental Market (AIM) Project, is to increase the pipeline’s capacity for delivering natural gas to New England, where the current pipeline capacity is blamed for higher energy costs. Much of the gas that flows through the pipeline to New England comes from fracking operations in Pennsylvania and other parts of the Marcellus Shale Region as well as the deep South.
It also looks like domestic natural gas producers, including fracking operators, could use the expanded infrastructure to export natural gas. Here’s an excerpt from an energy industry blog post:
Despite the challenges they would likely face, as many as four companies are exploring the possibility of exporting liquefied natural gas (LNG) from the Canadian Maritimes to Europe, Latin America and Asia... Now there is serious talk of reversing [Maritimes & Northeast Pipeline]. Spectra Energy, majority owner in MNP, in early February initiated an open season on the proposed Atlantic Bridge project, which would expand Spectra’s Algonquin Gas Transmission and MNP systems, and move Marcellus and other U.S.-sourced gas north on MNP into Maine.Exports could increase the demand for fracking and contribute to the continuing increase in the world’s greenhouse gas emissions.
One of several grassroots organizations that oppose the pipeline expansion, Stop the Algonquin Pipeline Expansion (SAPE), is against the project because it threatens to “exacerbate climate change, endanger our safety and quality of life, contaminate water, air and soil, cause harm to domestic animals and wildlife, and threaten farmland and property values.”

Rozzie Roofs Sprout Solar Panels
 |
| Photo: Eric Smalley |
The Rozzie Solar Challenge is making great progress. In less than a year 11 homes have added solar panels to their roofs and 11 more are in progress. If you (or anyone you know) are interested in learning about your options for putting solar panels on your roof, there will be a workshop on Monday, May 19 at 6:30 PM in the community room at the Longfellow House.
If your roof passes an initial online screening for suitability, you can schedule a no-cost assessment to determine if your home can go solar. Everyone who has the assessment will receive $50 in Rozzie Bucks, which can be redeemed at many shops and restaurants in Roslindale.
For more info, contact Josh Lynch of Next Step Living at josh.lynch@nextsteplivinginc.com.

The City and the Rising Sea
The April 4 issue of the Boston Globe Magazine has an article about the city's preparations for climate change: How Boston is — and should be — preparing for rising seas. The article identifies five things Boston is doing and five things Boston should be doing.
Five things Boston is doing now:
- Fostering public-private coordination
- Building with higher sea levels in mind
- Ensuring that the city's emergency services function without grid power
- Requiring developers to plan for sea-level rise
- Flood-proofing microgrids.
Five things Boston should be doing:
- Study a storm surge barrier
- Use its political and economic power to lead the state and the private sector
- Retrofit homes for flood preparedness
- Coordinate with neighboring towns and area universities
- Move vulnerable infrastructure and facilities inland

A Busy Week for Climate Activists
By Pam Sinotte
On Monday, February 3, braving snow and slick sidewalks, about 30 residents of Jamaica Plain and surrounding communities gathered for a “singing vigil” to protest the Keystone XL tar sands pipeline.
We were 30 of over 10,000 who gathered for vigils in 283 locations in 49 states (plus DC and Canada) to call on President Obama to reject the Keystone XL pipeline. As a light snow fell, led by the “Fossil Fuel Follies,” we sang climate action songs from their repertoire as well as songs by the recently deceased Pete Seeger. Responding to our signs, candles and song, simpatico drivers honked their horns.
Organized in just 72 hours by groups including CREDO, 350.org and the Sierra Club, the vigils were a response to the State Departments release, on January 31, of the Final Supplemental Environmental Impact Statement on KXL which states that the pipeline will have minimal environmental impact. The final decision to approve the pipeline, or not, will be President Obama’s.
The proposed pipeline would transport dirty tar sands oil from Canada through the U.S. to Gulf Coast refineries where, most contend, it will ultimately be shipped overseas. Many studies show that building the pipeline will accelerate climate change because of the amount of CO2 that will be added to the atmosphere when the oil is burned.
Five days later, on Saturday, February 8, 400 demonstrators from across the state turned out on Salem Common in Salem, Massachusetts, to protest the building of a natural gas power plant facility on the Salem Waterfront. We carried an array of homemade signs and banners, and sang and chanted our way from the Common to the Waterfront site of the proposed plant.
The new plant would be built by New Jersey-based Footprint Power, owners of the Salem Harbor Station, a 63-year-old coal- and oil-fired power plant that currently sits on the site but is scheduled to close by the end of May. The $800-million 674-megawatt natural gas power plant is slated for completion in 2016.
One rally speaker, Dorian Sosnick Williams, said with passion, “I am 22 years old and climate change is impacting every major decision I make…including the decision of whether or not to have children.” In a recent email, Williams wrote: “If this plant moves forward, it could set the precedent for all future retiring coal plants to be replaced with natural gas, stifling investment in renewables and locking us into decades of continued fossil fuel reliance.” Williams is Climate Legacy Coordinator for 350 Massachusetts and Energy Organizer for Better Future Project.
The rally was organized by 350 Massachusetts, Better Future Project and Salem-based Grassroots Against Another Salem Power Plant (GAASP).
An update: On February 20, State energy officials gave their final approval for the construction of FP’s proposed new plant. For details see New Salem power plant wins final approval.

City of Boston 2014 Climate Action Plan Update
By Pam Sinotte
What would Boston look like if Hurricane Sandy had hit Boston at high tide? This and many similar questions were explored as representatives of the City of Boston presented a draft of the 2014 Climate Action Plan (CAP) Update to members of non-profit organizations and neighborhood environmental groups last month. The new CAP will be completed and released by the end of 2014.
The Climate Action Plan contains a wealth of information; here are some highlights:
Some good news:
- Through community and individual action, emissions per resident and overall emissions in the city are declining.
- We are half-way to our goal of a 25% reduction in greenhouse gases (GHGs) by 2020.
- Boston was recently ranked the most energy efficient city in the U.S. based on our policies and programs, and the fifth best city for biking.
Some bad news:
- By 2047, the coldest years will be warmer than today’s warmest.
- Over 50% of our decrease in GHGs in the past five years came from something Boston doesn’t control – a switch from dirtier coal to cleaner natural gas power plants.
As Nancy Girard, Environment Commissioner for the City of Boston, said, “We’ve gotten all the low-hanging fruit – now we have to push harder. Climate action comes down to individual choices and neighborhood actions.”
Click here to see slides of what the 2014 CAP update will achieve, and how your choices can make a positive difference in reducing greenhouse gases. It’s worth taking a look just to see the dramatic slide of how a storm like Hurricane Sandy would impact Boston today and at mid-century.
One of the city’s goals is to engage 10,000 Bostonians in the 2014 CAP planning process and implementation. The City needs to hear from you! Here’s how you can participate:
- Join the conversation and share your ideas - go to Engage.GreenovateBoston.org.
- Attend or host a Greenovate Boston Meet-up
- Check out the Summit in April - we’ll post further information on this website as it becomes available

Making passive solar space heaters
By Eric Smalley
On November 16th, we were fortunate to have renowned woodturner and GreeningRozzie board member Beth Ireland lead a workshop on making passive solar space heaters. Twenty of us gathered at the Roslindale Community Center and learned to use hand tools.
We made 12” x 24”wooden boxes and we painted aluminum cans black.
We painted the interiors of the boxes black, put the painted cans in the boxes and covered the boxes with Plexiglas.
Placed in a South-facing window or other sunny spot, the heater emits a stream of warm air. The black paint absorbs sunlight, which warms the cans and the interior of the box. This warms the air inside the heater, which rises and exits through a hole at the top of the box. A hole at the bottom of the box lets air flow in, which allows a steady circulation through the heater.
Here’s a how-to video for making similar passive solar space heaters.
Here’s blog post by GreeningRozzie intern Hannah Pullen-Blasnik about passive solar heating.
