In order to use less energy and develop a better energy use pattern for myself and my family, I'm trying to be very conscious of every light and electrical device that I use. I only turn on a light when it's needed and turn it off as soon as possible. If there's ample light from outside, no need for lights to perform most tasks.
only use the radio or tv while I'm in the room. Unplug devices when not in use.
not sure how much energy it saves but I'm sure it adds up over the course of a year.
