I found it curious that I was given such a hard time for my routine the last time a post like this came up. Well, I'm a glutton for punishment, so here goes! The main theme is temps, but feel free to share recent upgrades, suggestions, etc.
Heat: all electric baseboard, non downstairs (ranch style with semi-finished basement used only for storage, laundry, hot water heater)
Last month, December, we were home the entire month and spent at least eight hours out in the main, large and open space, with the heat set to somewhere between 65-70F. Our bill was around $420 (2250 kWh used). This is unusual for us. We usually maintain:
Master BR: 60-68F all day and all night (we use a space heater with a digital thermostat, since the wall thermostats are ancient and wildly inaccurate!
-----I hate to admit it, but the 5 and 2 year-old sleep in our bedroom with us.
Rest of House: Thermostat remains OFF all day, except ~55-60F when we want to watch a movie on the larger TV or do some chore
-----I'll toss a space heater in the basement during cold weather (negatives F), but mostly the areas that aren't heated stay above freezing all winter long.
-----We have two larger-than-average skylights facing directly south in the living room and one normally-sized sky light in the bedroom.
Right now, the daughter is napping in the warm room, but my wife, son and I are out in the living room @ 51.5F, 49% RH.
-----I've got a hoody, scarf, beanie, and normal socks on
-----My wife is on the treadmill with just a hoodie and sweats on
-----My son and daughter rarely care how cold it is; we have to make them put more clothes or slippers on. My son takes after me most. He asked earlier to go out to get the mail for us barefoot rather than go through the hassle of putting shoes on.

I've found that I can FEEL cold at 70F and, like now, completely comfortable at 51F, depending on the day. I don't make anyone suffer. If any one of us is feeling cold, we turn the heat up. By up, I mean 10F or so to 60F+ which is pretty darned warm to me. I hate it when I come inside after working outside and it's a balmy 65F. I don't usually say anything about it, because I know I'll cool down and might get a chill, but the back of my mind screams, "wasteful!"
The same goes for all of our resource usages. I turn the shower off while lathering and I'm trying to instill in my kids that showers don't need to take more than five minutes. I actually prefer giving them a bath. Our house came with a large spa/tub and we have a smaller china-special tub within it. My kids LOVE baths and it likely uses less water than having them hang out in the shower for more than five minutes.
Actually, the wife and I haven't used the spa/tub even once. Well, that mainly because every time I've tried to clean it, more brown suds and slime come out of the plumbing.

The next step is to get a home energy audit to see what they can do, and what coupons they offer for upgrades. Our hot water heater is likely 20+ years old, though the pipes are all wrapped and I have two covers on it. With basement temperatures in the 50's, I shoved a thermostat down to the tank and it read 20F+ higher, so that's good.
Besides that, I know we need more insulation in the attic, however, the attic is a crawl space, with access only through a tiny square in a small hallway closet. At 6' tall and 200# I was able to scramble my way up there, but it was a tight fit.
