There are quicker and less costly measures that can be taken as well. One way to save money is to replace bulbs with fluorescents(荧光灯). This can result in a saving of more than 50% on your monthly lighting costs. When it s time to replace old appliances, it s wise to spend a bit more for an energy-efficient model, and be sure that you are taking advantage of energy-saving settings already on your current refrigerator, dishwasher, washing machine, or dryer.
