A year and a half ago I went on a wall wart power measuring exercise. I concluded that going around unplugging wall warts (8 lbs CO2/yr) wasn’t going to save the planet. If you want to save the planet, you’ll have to do hard things, like hang your clothes out on the line (.3 tons CO2/yr), drive your car half as much (3 tons CO2/yr), or turn off your geeky home server (.3 ton CO2/yr).
For me, saving energy is nothing new. We grew up getting yelled at for leaving the fridge door open, we set our thermostat back before set-back thermostats were fashionable, and in winter we left the water in the bath tub until it had cooled so the heat from the tub water would warm the house instead of the drain (I ain’t paying to heat the $#*&$^ drain!). My dad super-insulated our house before the 1973 oil crisis. We weren’t saving energy to be green though, we were just cheap.
