   Refrigerators and freezers are supposedly better insulated, use less water in washing machines blah, blah, blah………..The ones I’ve used don’t get clothes as clean I’ve found and drying takes forever using less heat so I don’t see how running the dryer longer cooler is any better than drying faster with more heat. Those two speed swimming pool pumps are a joke, they run at half speed so you have to run them twice as long.

   In Australia, they are tested for their consumption over a year so they are pretty reliable and the newer, more tecknologikally advanced are more energy efficient. In Australia, we have them on fridges, washing machines, dryers, and TVs with a special Star Rating system out of 5 – the more stars the more energy efficient. We also have a rating system for water usage using Drops instead of stars for washing machines and dishwashers – the more Drops the more water efficient. Most fridges save energy by being better insulated and can blow air inside without the compressor on to help even out the temperature and having better coils like a clean back and use higher compressors for more energy efficiency. Washing machines can have more direct drives to save mechanical losses and water level sensors to fill to just the right hieght, dryers can have sensors to stop as soon as the clothes are dry rather than run for a set amount of time, TV’s can have lower power consumption in standby mode and special energy saving features to reduce the back light and also have LCD rather than plasma.

   We also get the international energy star sticker on things like printers and computer equipment, It’s a different kind of sticker and they save energy by using less energy in standby modes and power down when not in use or when not actively being used.
