Learn About Energy Efficiency

We're committed to helping you understand the role energy plays in your life, and the practices that can help you use it efficiently and wisely.

Want to discover areas in your home that are wasting energy? It’s easy – just check out an Eversource “Kill-A-Watt” kit from your local CT library.

The kit allows you to explore three types of electric use: plug, lighting, and mechanical. The kits measure and record the amount of electricity consumed, and we provide you with a booklet that gives tips on reducing your energy consumption and costs.

See below for a list of libraries that have the kits in-house:
