A tip for if your place is too cold for the rise, and you don't want to run the oven that long: Bring a cup of water to a boil in the microwave, then push it back in a corner of the microwave, put your dough bowl in there, then close the door. It will be warm enough for the dough to rise, and draft-free, without spending so much on power. Of course, make sure everyone in the house knows not to try to use the nuker! You want the door to remain closed the whole time.
