Eversource customers in Bethel, Brookfield, and Danbury can check out a “Kill-A-Watt” kit from the local library. State Representative Steve Harding says this will help residents learn more about three types of electric use: plug, lighting, and mechanical. The device measures and records the amount of electricity consumed. The kit comes with a booklet that gives tips on reducing energy consumption and costs. In addition to public libraries in Bethel, Brookfield and Danbury, the kits are on hand at Long Ridge Library.
