Simple mindfulness practices around your home can be the starting point to a greener lifestyle. Try monitoring your water and electric light usage.
Water is the soothing backdrop to any type of cleaning, however gallons upon gallons can be wasted for this pleasant accompaniment. Turn the water off while brushing your teeth, and only run your dishwasher once a day or when its full.
If you are not physically in a room then there is no need to have it electrically lit. Turn off the lights when your not using them. Even try omitting electric light altogether during daylight hours.
