I actually have been trying really hard to keep our family Sundays, an "unplugged" day (no TV, no lights, no radio, no internet/computers, etc.). It's been nearly impossible to go through the whole day like this, but keeping it as a goal, makes us consciously reduce our use of electricity at home on Sundays and this energy conservation behavior is trickling into the rest of the week.
