People are becoming more aware of energy efficiency, and homebuilders have responded accordingly. While you can find tons of
prefab houses designed to be as green as possible, you dont have to go that far if you dont want to. You can easily choose a
prefabricated house that uses less energy or is better insulated than many traditional homes. That said, if you do decide to build a green home, there are plenty of advantages and only one downside (high initial cost) compared with traditionally built homes.
