When working on my computer in a lower level of the house I need more light, I have plants that need a grow light during the day. We also keep a night light on for anyone that needs to get up during the night. Trying to keep the bill lower takes some work, the temperature is set for 68 during the day and about 66 at night unless it is very cold out.
I unplug EVERYTHING when I leave the house. The only thing I keep plugged in is my refrigerator. Everything else is unplugged (including my stove). Yes, it takes time but eventually you figure out a system to simply things. I used to have power strips but realized it still drained energy. I've dramatically dropped my bill from a year ago.
We have lots of lights in our house and it is one of the main contributors of electric charge before. But right now we have change our lights to a much energy efficient led lights to save money. They last longer. We also make sure to turn off the light when we are going to sleep and during morning when we are in the office. We only used them when needed.
I suggest, in saving electricity, we should unplug each appliances because more or less the electricity is still active in 0.5 amount per second. Second is, figure out some alternatives in reducing the electricity such as the "Solar bulb" instead of LED. Solar bulb is much convenient and safer to use but otherwise the best thing to do is have the discipline because if all the appliances are in use, it is obviously not much healthy for you.
Home automation is a great way to save on electricity as well. And it does not have to cost a fortune to automate your home.

Personally, I only keep on about two lights in the house, an outdoor light, and my nightlight on throughout night. I should probably start keeping my computer off too, but I'm so accustomed to keeping it on sleep constantly. I wonder how much is wasted from leaving a television on. A family member does this, and it's irritating.
