On average, an old refrigerator uses about 35% more energy than a model that has earned the ENERGY STAR label.
The reality is as appliances age, their overall energy efficiency can drop significantly due to aging parts, malfunctioning controlling devices, bad seals, and other components.
Old refrigerators use a TON of electricity, so I wouldn't be surprised at $80 a month extra. It may be running the compressor all the time to keep cold, and using much more than when it was new.
If you swap out old appliances for more energy-efficient new ones, you'll not only save money on your utility bills but also help reduce greenhouse gas emissions. Updating your appliances is but one of many tips the Earth Day Network recommends for those who want to make a difference.
A 20-year-old refrigerator could use 1,700 kWh of electricity every year, compared with about 450 kWh for a similarly sized new ENERGY STAR model. At an electrical cost of 12 cents per kWh, that represents a savings of $150 per year and a potential payback of about 7-9 years.
While your old refrigerator may still look good and work well, if it is more than 15 years old, it's more than likely using a significant amount of energy -- in fact, more than twice the energy of a new ENERGY STAR certified model.
If you have electric heat, heating your home uses the most energy. This can account for more than 30% of your electricity consumption. And if you have air conditioning, this number rises even higher.

What costs the most on your electric bill? Heating and cooling are by far the greatest energy users in the home, making up around 40% of your electric bill. Other big users are washers, dryers, ovens, and stoves. Electronic devices like laptops and TVs are usually pretty cheap to run, but of course, it can all add up.
If there is a problem with your fridge's ability to cool efficiently, it will draw more power to compensate for it. Keep an eye out for faulty lining around the door. If the doors to your fridge/freezer are not sealed properly, cool air can escape and make your appliance work harder than it should.
Yes. Unplugging your appliances can reduce the amount of electricity you use each month and lower your carbon footprint. However, you might not notice much of a cost savings. It depends on how many appliances you unplug and your overall bills.
Consider replacing your old fridge and recycling your old second refrigerator. Refrigerators over 15 years old could be costing you more than $80 per year to run.
Older electric stoves usually consume more power than their newer alternatives. In contrast, energy-efficient stoves consume less and deliver more. If you want to buy an electric stove for your kitchen, make sure it is energy-efficient and supports advanced cooking techniques.
Most people will see that they have a lower tariff overnight, usually between 11 pm and 7 am. This is the best time to do your washing as you'll save money. Saving money on electricity is only part of the equation. In order to get the best possible wash, you also need to use top-quality products.
For most households, electricity rates are highest between 4 and 9 pm. During this time, people are using more energy, gas-powered production typically starts up to meet increasing demand, and the supply sources are more expensive.
December is prime time to find clearance sales on household appliances, especially after Christmas. After the holiday season, stores often slash prices even further to move any leftover stock. This is an excellent time to buy if you're looking for a deal, particularly on floor models and discontinued items.
Which appliances use electricity even when turned off? You would be shocked by how many appliances continue to use electricity even after they've been switched off. Any appliance with an LCD, light, or clock, such as your DVD or DVR player, cable box, television, or microwave, consumes electricity even when turned off.
The Givoni or Woods diagrams show a direct relationship between air speed and the drop in temperature felt by users of the room. In this case, a ceiling fan will consume between 20 and 50 watts (still a long way from the consumption of an air-conditioning system (800 to 1500 watts, i.e. 30 to 40 times more).
Your electric bill is likely to account for the highest expense on your monthly utility bill. Most Americans find their electricity usage is 41% heating and cooling, so that's often the biggest expense.
Room air cleaners are portable, electric appliances that remove fine particles, such as dust and pollen, from indoor air. A standard room air cleaner, operating continuously, uses approximately 450 kWh per year in electricity. This is more than the energy used by some new refrigerators!
