To start off, I am working on ways to do it without altering your life at all, then I'll work on slightly bigger changes. Let's be honest though, we all live the way we do because it works for us, and we need to maintain a way of life that will still work.
Turn off the breaker to your outdoor plug at night and turn it back on when you get up in the morning, a car only needs to be plugged in for 2 hours
Unplug your laptop when not using it (or when it is in use but fully charged) This will also save money on replaceing the battery
Use a toaster oven when possible (also keeps the house cooler in the summer)
Turn down your furnace at night, you will sleep better and save!
Invest in quality plastic containers for your baking goods and other pantry items. They will last longer then cheap or disposable solutions and keep food fresher longer too
Let your hair air dry a bit before you use the hair dryer
Unplug appliances when not in use (NOT the fridge...) blenders, stereos, coffee pots, etc
Turn off lights when you leave a room
Plan computer usage so you can turn it on once and get everything done
