When purchasing new appliances, consider the purchase price, the cost to run, and the life expectancy of the appliance. The operating cost can be found on the appliance’s black and yellow EnergyGuide label. This label shows the average annual cost to run the appliance, and how it compares to other models in kWh used per year. A retailer can tell you the appliance’s life expectancy. Then do the math: Consider a refrigerator for $549 that costs an estimated $70 per year to run. Over 15 years the homeowner will spend $1050 in energy costs. A more efficient refrigerator selling for $749 might cost $50 per year to run. The homeowner will pay just $750 in energy costs over 15 years, a $300 savings and an energy-conscious purchase to boot. With energy costs on the rise, those savings could be even greater in the long run.
If your wood gluing work is less than successful, check your blades. If the blade in your saw is getting dull, it can loosen (but not remove) a layer of fibers on the edges to be joined. Later, glue may not be able to penetrate through this debris to solid wood, resulting in weak joints. A signal that this may be the problem is if ruptured joints are coated with fibers.
