The laundry room is an easy place to start greening your home, as it has only three major components: appliances, products, and clothing. Yet this small room greatly impacts the water consumption and energy use of your home.

If you want an energy-efficient replacement for an old tank water heater or if you have limited space for a tank heater, like in a cabin or condo, then going tankless can be a great option. Tankless, or on demand water heaters operate on a simple principle: Heat water instantly and only when you need it. It's a great tool for conserving energy in your home.

Another green cleaner in its own right, and a good partner to baking soda, vinegar is a wise substitute for harsh commercial cleaners.

More than a baking ingredient, this common household product does everything from deodorize to polish. It can even fight fires.
