Energy at Home:

What are some ways to conserve our energy or get it from a more sustainable source? Resources: Wellesley’s Power to Choose Program:, Get a Mass-Save Home Energy Assessment:, Solar Panels:

Protect our Resources:

Did you know that we have groups in Wellesley that work together to protect our waterways from litter, chemical runoff, etc? Explain what they do, why it’s important, and how residents can help. The Wetlands Protection Committee:, Friends of Brookside:

Judging Criteria:

Submissions will be scored on a scale from 1-5, based on the following criteria:

  • How well does the project explain the problem and its environmental impact, using data / examples?

  • How well does the project provide a specific solution to the problem, with data or examples on how this organization/behavior/resource makes a positive impact?

  • How compelling, convincing and creative is the project?

  • Are sources cited, does the project meet length requirements, and does it have correct grammar and data?

A winner will be selected by panelists from Wellesley Green Schools from each school level (Elementary (K-5), Middle (6-8) and High (9-12)).

With great disappointment, we offer an update on the fate of some environmental provisions during the 2017-18 state legislative session, which ended on July 31. We expected our State Legislature to act with vision and courage in the face of disastrous effects of climate change unfolding daily, world-wide — catastrophic wildfires, dangerous storms, record-breaking temperatures, animal die-offs, rising sea levels. They did not.

Sadly, the House shot down the appropriately ambitious legislation that passed in the Senate. We saw no leadership or sense of urgency from the governor, who might have influenced the House to act boldly. In the end, only a modest clean energy bill was enacted (H.4857) — a bill that is not commensurate with the climate crisis we face and that includes a shocking provision that allows trash incineration to be defined as a source of clean, renewable energy.

To quote State Senator Jamie Eldridge (D-Acton), “There is a serious problem with democracy in Massachusetts, when the voices of tens of thousands of concerned residents and climate change activists, and dozens of clean energy advocacy groups, are ignored. The battle is not just in DC, it’s here, too.”

So — before we review the results — we want to urge you to VOTE this fall in the primary elections on September 4 and the general election on November 6We have an important race for governor coming up, as well as other state and federal elections. Find candidates who will stand up and fight for our planet and our future — instead of those who step back and stay silent. Go to candidate forums, ask tough questions, and then ask your friends and family to vote with you. We can’t count on national leadership right now, so let’s make sure officials at every level of state and local government are ready to take action on environmental issues.

Here is a quick round-up of a few key environmental measures we were tracking during this session, followed by links for more details:

Renewable Portfolio Standard (RPS): The is the state requirement that specifies the percentage of electricity that utility companies must obtain from qualified renewable energy sources. Under current law, the RPS is 13% and it increases at the rate of only 1% each year. The new law raises the rate of increase to 2% a year starting in 2020, but reduces it back to 1% by 2030. At this level of increase, Massachusetts will fall behind the 2030 RPS mandates of California, New York, Oregon, Rhode Island, and many others. It also means that Massachusetts will reach an RPS of only 36% by 2030, and a 56% by 2050. We note with gratitude that Wellesley’s State Representative Alice Peisch supported a House amendment that would have raised the RPS increase to 3%, but House leadership ultimately forced the withdrawal of that amendment.

Gas Leaks: The clean energy bill that passed included provisions that would require utility companies to provide more information about gas leaks to the Department of Public Utilities (DPU). The new law defines how utility companies should measure “lost and unaccounted” for gas — which is the difference between the amount of gas purchased by the gas company and the amount that is actually delivered to customers or used by the gas company in its operations. Utility companies must also identify and measure the sources and locations of the lost and unaccounted for gas. The new law also allows the DPU to grant waivers for the development of innovative projects that reduce lost and unaccounted for gas in order to reduce the cost to ratepayers and reduce greenhouse gas emissions. (Methane from gas leaks is at least 80 times more potent as a greenhouse gas than carbon dioxide.) State Senator Cynthia Creem (who represents Wellesley Precincts A, C, D, E, and H) was a strong advocate for action on gas leaks. 

Plastic Bags: The House blocked a state-wide bill passed by the Senate that would have banned single-use plastic bags. More than 80 cities and towns in Massachusetts — including Wellesley — have bylaws banning the bags. The state bill would have created a uniform regulation that was intended to reduce plastic litter and the hazard that plastic bags pose to animals and our environment. Both State Rep. Alice Peisch and State Senator Cynthia Creem have supported plastic bag bans in the past.

The Wellesley School Committee recently sent this letter to National Grid at the request of the Natural Resources Commission and Wellesley Green Schools, asking that the utility company take action on gas leaks near Wellesley schools and preschools.

An independent survey by the NRC last year revealed extensive leaks throughout town, including a number of leaks in or near school zones. Click here for a map showing Town-wide gas leak data

Earlier this month, the NRC invited Zeyneb Magavi, Research Director for HEET (Home Energy Efficiency Team), to speak at the Wellesley’s Green Collaborative about the state-wide efforts to address gas leaks. Ms. Magavi spoke about the partnership HEET has formed with gas companies National Grid, Eversource, and Columbia Gas to devise a reliable method to identify the largest volume gas leaks for urgent repair. She also explained HEET’s efforts to help homeowners and builders transition from fracked gas to electricity for heating and cooling, and appliances.

She also addressed the serious issue of fracking – the process of injecting toxic chemicals and high-pressure water into fissures in underground rocks to extract gas. The gas we use in New England is fracked in Pennsylania. With HEET, Magavi is working to build relationships with families in Pennsylvania who have been devastated by the health impacts fracking.
