Yah. Thought about firing up the woodstoves, but that's just recycling carbon. Might goose the thermostat all the way up to 65F for the hour, but will have to let it fall back after if I'm going to sleep tonight.
The rest of it, I'll just trip lightly (ha) through the house turning on all our CFLs to produce lots of light at low expense to the pocketbook. (Somehow I don't think this is the purpose, but it's the best I can do.)
