I have a baby buck insert in the fireplace, and can burn either wood or coal. The wood pile is big enough to last a month, but I think this year I will invest in a ton of coal, and break it up and pack it in 5 gallon buckets with lids and stack them in the garage. After reading Jack London's To Build a Fire and having come close to living it, I am determined to not succumb to the energy nazis' insanity.
I'm not much on the idea of cooking over a coal fire, though...
