Electricity
It's getting nicer out, and I'll have to go and build a fire some night. I have plenty of downed branches saved up that I need to get rid of anyway. Firelight is nice, especially on a clear night.
Luckily, I don't need to rely on it. I don't use a lot of electricity, even with a file server running all the time. And that's not strictly necessary. Electricity is a great thing when you think about it, light when you want it, without the danger of fire.
When it's there, of course. My power is fairly reliable, with only one really long outage I can remember while I've lived here. Otherwise it's flickered now and then. But, it works. And it works well.
