October 19: Greening the Grid: Preparing for Our Clean Energy Future

Greening grid flyer 2Speakers: Ariel Horowitz, PhD, Synapse and Megan Herzog, Staff Attorney, Conservation Law Foundation, MA.

The electric grid is an essential part of the energy infrastructure that will support increased clean energy sources. In order to successfully transition to clean energy, the grid must be able to handle the increased demand.

The Forum will address:

  • What is the electric grid and who runs it?
  • Why is the grid important as we transition to clean energy?
  • How can the grid be modernized to support the transition?

A Question and Answer session will follow.

This event is part of LWVMA’s Climate and Energy Solutions Series. It is free and open to the public.

#WeAreStillIn – Lexington joins the Paris Accord.


Lexington Board of Selectmen voted to have Lexington join the Compact of Mayors who will adhere to achieving the goals of the Paris Accord!

We have already been on this road through the actions by Sustainable Lexington, Town Meeting and the Town Manager and the employees of the Town of lexington.

This is not just a symbolic gesture (which is important), but by joining the US Compact of Mayors we have agreed to develop an energy and emissions baseline (Done), conduct a climate vulnerability analysis (Done), set emissions targets (Done), adopt a climate action plan (Drafted but not formally adopted yet), and perhaps most importantly to take the actions necessary to achieve our emissions targets (Ongoing).

Finally, we have agreed to report our performance against these goals at least annually to the US Compact of Mayors, who will in turn report our overall performance to the UN as part of our collective commitment to achieving the goals set forth in the Paris Climate Agreement.

Also, the US Compact of Mayors has pledged to give us technical assistance (at no charge) to help us achieve these goals.

The Compact of Mayors was formed by Mayor Michael Bloomberg in September of 2014 at the UN Climate Summit. The Compact of Mayors officially merged with the Covenant of Mayors on June 22, 2016. The newly created Global Covenant of Mayors for Climate and Energy unites more than 7,100 cities in 119 countries across six continents in the shared goal of fighting climate change through coordinated local climate action.

Lexington Leaps Forward on Considering Climate Change!

February 27 was the night the Town of Lexington decided that our next school will not use fossil fuels to heat the building! This is a really important decision for our health and for our future. 

The Town of Lexington also approved the Community Choice Aggregation program – that we hope will move our electricity to 100% renewable energy all at lower costs than Eversource’s basic service rates. 

Thanks to everyone at Sustainable Lexington for bringing these initiatives to our Board of Selectmen and to LexGWAC and Mothers Out Front who supported these initiatives. 

We still have a lot of work ahead of us, but we are making good progress by working together. Thank you!!! 

Why all these actions are so important for all of us – can be explained in part by an article that was published in 2015 – outlining the reasons why we all need to stop deploying fossil fuel infrastructure by 2018.  Here is a short segment from the article:

In only three years there will be enough fossil fuel-burning stuff—cars, homes, factories, power plants, etc.—built to blow through our carbon budget for a 2 degrees Celsius temperature rise. Never mind staying below a safer, saner 1.5°C of global warming. The relentless laws of physics have given us a hard, non-negotiable deadline, making G7 statements about a fossil fuel-phase out by 2100 or a weak deal at the UN climate talks in Paris irrelevant.

“By 2018, no new cars, homes, schools, factories, or electrical power plants should be built anywhere in the world, ever again unless they’re either replacements for old ones or are carbon neutral? Are you sure I worked that out right?” I asked Steve Davis of the University of California, co-author of a new climate study.

“We didn’t go that far in our study. But yes, your numbers are broadly correct. That’s what this study means,” Davis told me over the phone last fall.

Davis and co-author Robert Socolow of Princeton University published a groundbreaking paper in Environmental Research Letters last August, entitled “Commitment accounting of CO2 emissions.” A new coal plant will emit CO2 throughout its 40- to 60- year lifespan. That’s called a carbon commitment. A new truck or car will mean at least 10 years of CO2 emissions. Davis and Socolow’s study estimated how much CO2 will be emitted by most things that burn oil, gas, or coal, and it is the first to actually total up all of these carbon commitments.

Based on their work, I estimated that if we continue to build new fossil fuel burning stuff at the average rate of the last five years, we’ll make enough new carbon commitments to blow through our 2°C carbon budget sometime in 2018.

“Is that really where we are?” I asked Davis.

There was a pause, and I could hear the happy sounds of children playing from his end of the phone. Eventually Davis said “yes, that’s where we find ourselves.”

Lester Brown discussing Transitioning to Solar and Wind

Lexington Approves Community Choice and Divestment!

Lexington’s Town Meeting approved the Community Electrical Aggregation article and the Divestment from Fossil Fuels article taking two more important steps toward sustainability and addressing climate change!

Community Choice Article: 

The largest source of Lexington’s emissions comes from our electricity consumption. How can the Town of Lexington help local residents and small businesses switch to cleaner and cheaper electricity?

The Board of Selectmen is planning to submit a warrant article asking Town Meeting to authorize the Town to enter into a Community Choice program that would consolidate residential and commercial retail electricity demand in order to seek proposals for cheaper and cleaner sources of power on behalf of our residents and businesses.

We are lucky to be living in Massachusetts, one of only 5 states in the country that allows local residents and businesses to collectively choose a competitive supplier by pooling their buying power with the goal of choosing a cleaner and cheaper supplier for our electricity.

All electricity consumers in Massachusetts have the option to select a competitive retail electricity supplier. But only 10% of Lexington’s residential customers have switched to competitive suppliers. It is not hard to understand why so few have taken advantage of this opportunity. Picking a vendor can be complicated and time consuming, and many residents are concerned they might not have enough information to make a good choice.

In contrast, 86% of the electricity consumed by Lexington’s commercial customers comes from competitive electricity suppliers. Large commercial customers have proven that they can effectively obtain lower rates by switching to competitive suppliers. The Town of Lexington has also had great success with our competitive supplier, purchasing electricity for 22% less than the NSTAR Basic Service rate last year. With the recent rate hikes, the Town is looking even smarter. Our long-term supply agreement allows the Town to buy electricity at half the rate of NSTAR’s Basic Service rate and get cleaner energy than NSTAR’s Basic Service!

If approved, the Town’s electricity broker would develop an aggregation plan that would be reviewed and approved by the Board of Selectmen, the Massachusetts Department of Energy Resources and the Department of Public Utilities. Once the plan is approved, the broker would solicit bids for cleaner and cheaper power, all at the broker’s own cost and risk.

Customers would continue to receive one bill from NSTAR and NSTAR would continue to provide electricity delivery, emergency services and customer support. Individual residents and businesses would retain the right to opt-out with no penalty and choose any other competitive supplier or the default Basic Service energy supply provided by NSTAR. Many local governments are achieving a powerful range of objectives for their residents and businesses using Community Choice programs:

• Competitive, often significantly lower, electricity rates

• Transition to a cleaner, more efficient energy supply

• Consumer choice, consumer protection, & local control If that sounds good to you, ask your Town Meeting members to approve the Community Choice warrant article.

Draft Warrant Article: To see if the Town will vote to authorize the Board of Selectmen to enter into a Community Choice Aggregation Program and contract for electric supply for Lexington residents and businesses as per MGL 164, Section 134, or act in any other manner in relation thereto.

Comment: The Commonwealth of Massachusetts, by enacting Chapter 164 of the Acts of 1997, has established a competitive electricity marketplace. The residents and businesses of Lexington have substantial economic, environmental, and social interests at stake and are interested in reducing their electricity emissions and rates. If a Community Choice Aggregation program is implemented in Lexington, individual residents and businesses would retain the right to opt-out with no penalty and choose any other competitive supplier or the utility’s default Basic Service energy supply. NSTAR

Divestment Article

Fossil fuel companies have five times more carbon in their underground reserves of coal, oil and natural gas than can be burned to stay below the internationally agreed upon 2 degrees “safe limit” to curb the worst impact of global warming.  Yet, it is in their business plan to burn it, and they spend 1.6 billion dollars every day exploring for even more. Instead of leading the transition to clean energy, fossil fuel companies have used their tremendous financial resources on lobbying to block political action on climate change and on misinformation campaigns to cast doubt on the science and confuse the public.
Yet some of our Lexington Town funds and state retirement funds are invested in these fossil fuel companies.  Our ownership of these investments carries with it our responsibility for the actions of these fossil fuel companies.  According to Bill McKibben, Lexington-raised author and environmentalist, “If it’s wrong to wreck the planet, it’s wrong to profit from this wreckage.”  In addition fossil fuel investments have become “risky business.”  A resolution on the upcoming town warrant proposes that Lexington get out of fossil fuel investments in its Retirement and Public Trust funds and that town authorities urge the state retirement fund managers to do the same.

People’s Climate March

We said it would take everyone to change everything — and everyone showed up!

We Made History! Now it is Time to Change Our Future!

“We are the first generation to feel the impact of climate change and the last generation that can do something about it.”

We Demand Action – Not Words

We Are Everywhere – And We Are Rising

It is Time To Answer the Call

Leonardo DiCaprio – Opening Climate Summit 2014

“Clean air and a livable climate are inalienable human rights.” – Leonardo DiCaprio

Obama At Climate Summit 2014

“There is one issue that will define the contours of this century more dramatically than any other, and that is the urgent and growing threat of a changing climate.” – President Obama

“The climate is changing faster than our efforts to address it. The alarm bells keep ringing. Our citizens keep marching. We cannot pretend we do not hear them. We have to answer the call. We know what we have to do to avoid irreparable harm. We have to cut carbon pollution in our own countries to prevent the worst effects of climate change. We have to adapt to the impacts that, unfortunately, we can no longer avoid.” – President Obama addressing the UN Climate Summit 2014

Disruption Movie


To view the movie online go to:

The People’s Climate March made a movie.  Disruption weaves together political intrigue, mind-blowing science, and an insider’s view of the largest climate mobilization in history. It features some folks you will find familiar (like Bill McKibben and Naomi Klein), and brings some fresh faces and exciting new stories to the fore.  Disruption built energy and excitement for the big march in New York City on September 21 which attracted 400,000 people into the streets of Manhattan.

Write President Obama to say NO to Keystone XL Pipeline!

Click here for a handout to give to others.

Keystone XL  Update: The EPA has registered concern about the State Dept.’s Supplementary Environmental Impact Statement, together with over a million citizens.  President Obama has the last word on this carbon intensive project.

You can help.

Your comments to President Obama are essential.

Write President Obama: (preferred)
Or:  The White House
1600 Pennsylvania Avenue NW

Washington, DC 20500


Obama should say no to Keystone XL, because doing so would help to limit development of the Canadian tar sands, and because we really wouldn’t get any significant benefit from saying yes; no real oil security, few permanent jobs, and most of the money goes to Canada and to Texas refiners in tax-free zones. Rejecting the Keystone XL permit makes a statement that it is time to stop investing in technologies that lock us into continued fossil fuel use, and it is time to make a strong commitment to energy efficiency and renewable energy.

The U.S. State Department released a 2,000-page analysis finding no compelling environmental reason to block the Keystone XL pipeline, the first direct link between one of the largest oil reserves on Earth and the world’s most advanced refining center on the Gulf of Mexico.  The State Department assessment has a number of serious flaws, that include downplaying the direct and indirect climate impact of the Keystone XL.

Cooler Smarter: A must read

Based on a comprehensive two-year study of hundreds of consumer decisions by the Union of Concerned ScientistsCooler Smarter: Practical Steps for Low-Carbon Living is a new science-based consumer guide that offers the facts on what decisions make the biggest impact on reducing your carbon emissions and what decisions don’t add up to much. The experts at UCS debunk many eco-myths, like the importance of “food miles” or the superiority of all hybrid cars, as they provide the science behind the right decisions that will save money and help save the planet at the same time.

In conjunction with the publication of Cooler Smarter, the Union of Concerned Scientists has issued a 20% Challenge. Their research has shown that by using the more than 20 methods outlined in Cooler Smarter, you can cut your carbon emissions by at least 20% in 20 days or less.

Climate Extremes

The answer to the oft-asked question of whether an event is caused by climate change is that it is the wrong question. All weather events are affected by climate change because the environment in which they occur is warmer and moister than it used to be….

The air is on average warmer and moister than it was prior to about 1970 and in turn has likely led to a 5–10 % effect on precipitation and storms that is greatly amplified in extremes. The warm moist air is readily advected onto land and caught up in weather systems as part of the hydrological cycle, where it contributes to more intense precipitation events that are widely observed to be occurring.
