"Ed Arildson did an ""energy makeover"" at his Bellevue home, including going to fluorescent light bulbs and buying a more energy-efficient refrigerator. The effort didn't save a dime under Puget Sound Energy's two-tiered rate, which encourages switching power consumption to off-peak hours. The Arildsons did save money by lowering their overall electricity consumption. But they would have saved even more if they had not been on time-of-day billing.
