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.

When cooking a casserole or a yummy chocolate souffle, use ceramic or glass baking dishes; these materials outperform metal and will allow you to lower the temperature of the oven by 25 degrees Fahrenheit. Lower heat means less energy.
