look at the energy efficiency of modern dishwashers, refrigerators, and washing machines which can save up to 75% of energy compared to the appliances in the average house (especially if they are older than 20yrs) . It makes plenty of sense to update them taking advantage of the approved rating systems.
Keep in mind that front loader washing machines use less energy that top-loaders, Refrigerators with a top or bottom freezer use less energy than their side-by-side counterparts, and it will aid in the fridge’s efficiency to position it away from the sun or windows. Dishwasher technology is developing in such a way that in order for a current model to gain an approved ‘Energy Star’ it must be over 40% more efficient than the average standard in 2007.
