Address your "standby" habits. Unplug mobile phone chargers and any unused appliances. 8% of electricity consumed at home is from "vampire" appliances that we aren't even using.Now THIS is one of my favorite things: saving electricity by unplugging unused applicances. But instead of physically unplugging things, I use the easy way out: I plug them into power strips. Then I can just flip the switch and effectively "unplug" several gadgets at once.
This has an incidental function of surge protection and also getting my various electronic things nicely organized.
WARNING: there is ONE exception to this rule. My internet connection seems to go fluky if repeated power cycled. It got to the point, a few years back, that after a couple hundred power cycles, it would take several hours for the internet box to restore its connection. A tech finally hinted that I just had to leave it on all the time, or the problem would get steadily worse.
Otherwise, before I go to bed I run a circuit. I check the doors to make sure they're locked. I check the catfood dishes, to make sure they're need. And I flip the power bars "off" so I'm not burning juice all night. It's easy and, in a way, a comforting little evening ritual!
