Stop wasting heat. If your home runs on a central heating system, close the vents in little-used rooms like spare bedrooms or the dining room. By restricting the flow of warm air into unused rooms, it'll be diverted into rooms that need to be heated. The warmer those rooms get, the more you can lower the thermostat.

Buy energy-saving products in bulk to save money. Ask your co-workers or neighbors if they want to buy pricier green products together -- compact fluorescent lightbulbs, surge protectors, outdoor solar lighting -- and then buy them through an online wholesaler to save money. The more you order, the lower the per-unit-cost will be. Be sure to get everything ground-shipped; it uses less fuel than air shipping.

Bonus tip: Countertop convection ovens save even more energy -- the smaller the oven, the faster it'll heat up.
