Here in Cambridge, MA we’re all too familiar with frigid winters. We may consider ourselves all-star thermostat programmers, but how many of us know in detail where the heat comes from? Most of us, knowingly or not, count on electric resistance baseboards, oil furnaces, or gas boilers to warm our homes and occupy our heating bills.

With increases in renewable generation and advances in battery technology, the energy storage market has begun to take off, especially for small-scale batteries.

The final numbers are in, and the results are impressive. Final 2015 assessments indicate that both Massachusetts and Rhode Island surpassed their electric energy efficiency savings targets. Once again, these efficiency leaders push the perceived limits of efficiency programs—demonstrating that energy efficiency programs can achieve electricity savings above or near 3 percent of sales.
