Eversource is offering some tips for keeping energy costs down in the winter.  They include switching to LED lights, weatherizing the home by caulking and weather-stripping all doors and windows and insulate or increase the amount of insulation in the attic, basement and outside walls.  Eversource also suggests setting  programmable or smart thermostats as low as is comfortable when at home and awake and lower when sleeping or away from home.  A Home Energy Solutions home energy audit involved a certified technician checking for and doing on-the-spot improvements like replacing old lighting with LEDs, sealing up drafty doors and windows and closing air gaps around pipes.
