During the past 30 years, home appliances have steadily become more energy efficient. A microwave oven uses 90 percent less energy to cook a meal than a conventional gas oven, and compact fluorescent light bulbs can offer light similar to incandescent bulbs but use 75 percent less electricity to do so. Refrigerators now use less than half as much electricity as those built in the 1970s. So when you decide to purchase new appliances, make sure they're high efficiency. The higher up-front price will save you money in the long run.
Is your refrigerator running? Well, you better go catch it. And when you do, test its vitals.
Sure, microwaves are fine for Hot Pockets, but sometimes, you just can't beat the stove.
The best thing you can do to reduce your electronics energy use is it to turn off equipment
