Why Solar-with-Storage is a Leap Forward

, Senior energy analyst

Falling costs for both renewable energy and batteries has led to amazing offers to build hybrid plants. In regions where utilities seek contract price bids from new plants, renewable-storage hybrids are winning in side-by-side competition with conventional power plants. Understanding energy storage has become all the more important as the current wave of power plant proposals pair storage with renewables. Read more >

Storage Could Catch Up to Wind and Solar’s Quick Growth

, Senior energy analyst

In recent years, the use of renewable energy has grown so much that three states (Iowa, Kansas, and Oklahoma) have over 30% of their electricity production coming from wind power. Presently, solar is the fastest growing energy type, and annual construction of solar is now beating both gas plants and wind farms in some years.

Renewables Will Be 80% of New US Electrical Generating Capacity in 2020

, Senior energy analyst

There’s good news in the latest near-term electricity prognostications from the US government: Renewable energy, the projections suggest, will account for 80% of the generating capacity to be installed in the country this year, with both solar and wind looking set to have record years. And that’s all setting us up to pass yet another exciting clean energy milestone, about renewable energy’s contribution to our nation’s electricity supply.

Residentes of East Boston protesting Eversource's proposed substation GreenRoots

Open Letter Demands Clean Energy Alternative to Risky Eversource Substation

, energy analyst

En español

This is the fourth of a four-part blog series on East Boston, a Controversial Substation, and Opportunities for a Clean Energy Transition.  

In recent weeks via this blog we have explored a proposal from Boston-area electric utility Eversource to locate a risky high-voltage substation in a densely populated neighborhood in East Boston. We have covered the characteristics of East Boston and the range of environmental justice issues it faces, the community’s concerns around the project, and our own analysis of a local clean energy alternative.

This blog post is aimed at the decision-makers who are tasked with determining the wisdom of allowing the project to proceed, or of requiring more information and a more reality-based exploration of risks and opportunities. Below is an open letter from Juan Ramos, a Union of Concerned Scientists colleague and a resident of East Boston, asking the Massachusetts Energy Facilities Siting Board (EFSB) to listen to the people of East Boston; to base their decision on up-to-date, transparent, and sufficient data; and not to approve the current substation proposal from Eversource. Add your name to this open letter! Read more >

Solar Keeps Getting More Efficient, Less Expensive, and More Resilient

, Senior energy analyst

The latest annual data on US solar energy show how the technology options for residential and commercial customers keep progressing. Here are three important dimensions of that progress: photovoltaic (PV) modules keep getting more efficient, PV system costs keep coming down, and batteries are becoming much more a piece of the solar picture.
