Better in terms of reliability, I'm sure – but what about efficiency?

I recently was in the market for a new dishwasher.

I compared the EU eco labels (which are based on water and energy use).

Buying the worst possible eco label currently on the market, and comparing it against the best two:

A label dishwashers cost almost twice as much (up to €400 more)
ombined energy and water costs saved over the lifetime of the device (which I optimistically set for 10 years at three cycles a week) is less than €100 euros
If you're not into money, but more concerned about the planet, think about it this way: how much damage could €100 in energy and water spread over 10y really be causing our planet?
These savings are only achieved if you use the most ecological program, which fails at it's primary job, which is cleaning dishes.

If I could find a decent 90s model for which parts were still widely available, I'd buy that instead. I truly doubt that burning through these poorly made newer devices are sufficiently more ecological than just using a old machine for a longer time.

In my experience it cleans just fine? Maybe your dishwasher just sucks

Efficiency is a double-edged sword manufacturers will manipulate how efficient their appliances are to make it look as though they're compliant.

For example new washing machines for clothing advertise to use very little water which technically they do. The problem is that they will drain and rinse several times throughout the cycle. Which in turn makes the cycle significantly longer.

A washing machine from the '70s used about 15 to 20 gallons of water per cycle but the cycle itself lasted for about 30 minutes.

Now a washer will use 5 to 10 gallons of water per cycle but the cycle is almost 2 hours long. The savings in water compared to the usage of electricity cancel each other out gaining you absolutely no increase in inefficiency.

A refrigerator from the mid to late '90s used about 40 to $50 a year in electricity new refrigeration uses $30 a year in electricity the increase to efficiency is so small that it's completely negligible.

And keep in mind modern appliances are nothing more than convenience. Aside from refrigerators of course, things like dishwashers clothing washers clothing dryers we don't actually need any of those we can do all that stuff by hand.
