They look sleek, grant you more storage space and are better for the environment, but did you know that using front-loading machines will also save money on your power bill? Front-loading and high-efficiency, top-loading sets that are Energy Star qualified can save you anywhere from $45 to $125 per year on power costs, depending on the model and how often you use it. To qualify for an Energy Star seal, washing machines must use 11 percent less energy than their older counterparts. Also, since energy-efficient models spin faster, they more effectively reduce moisture. This equates to less time spent in the dryer. So unless you enjoy higher power bills, you might want to consider springing for a high-efficiency, front-loading set.
