Cutting the cost

For small portions, reheating and single servings, the microwave beats the oven comfortably, because it heats the food rather than a big empty cavity. Cover dishes to trap the steam and heat evenly, and stir partway through. Its standby draw is trivial next to how you cook, so the real win is simply reaching for it instead of the oven on quick jobs.
