But one thing I usually don't do is shut my late 2012 27-inch iMac off at night or let it go into sleep mode. We shut off lights when they're not needed, and all of our appliances are Energy Star certified. My wife and I both drive high-MPG vehicles, we keep our thermostat at a relatively chilly 62☏ during the daytime hours in winter, and we don't have air conditioning in our home.
When it comes to saving energy, I think I do pretty well.
