> In terms of total energy use, it’s almost certain that a ten-year refrigerator should be replaced, for example. Argh! This is such BS! I'm so sick of hearing this. My parents had a 30+ year old fridge they replaced recently. The energuide sticker on the old one said it's total annual power usage was only marginally less than their brand new one. You'll almost never make up the cost of replacing something based on power usage alone unless you're starting off really inefficient, or power costs a ton. Refrigerators have gotten better in the last 30 years, but they're not computers, they don't double in efficiency/performance every other year (which isn't true of computers anymore either). The math was probably all worked out in the 60's and it's been marginal gains from material science improvements ever since. Most appliances aren't that complicated. Fridges are insulated boxes with a compressor and a thermocouple. If you read the reliability reports from consumer reports, you'll find that the simple (cheap) fridges all have top marks in reliability. All the fancy ones, it's all their fancy parts that break. I have never understood why people just buy the idea that a major appliance that is 10 years old is so inefficient that you should replace it without consideration. |
