Though there might be an element of misuse. My machine warns in the manual to do a 60or 90 degree wash with no clothes every couple of months to clean the machine. I suspect most people don’t do this.
Front-loaders are vastly different between the North American market and Europe or Korea. I remember my friend's brand new LG in California would run an eco-friendly cycle in 40 minutes. A similar model in Europe takes 4h30!
If anyone is looking for ideas on how to make the world a better place, look into figuring out how to shift the culture so that air drying becomes more common. Also composting toilets.
Edit: Drying clothes uses 56 billion kWh of energy in the US.[1] Another related area that needs work is standby power.[2]

Socially, improving commuting infrastructure so people waste less gas would easily have a larger benefit and you are not going to fight nearly as hard.
Etc etc, this might be top 50 but it's not a top 10 and it's hard.
People waste so much energy without thinking about it and for reasons that aren't particularly more convenient, like using disposable dishware instead of just rinsing off your plate when you're done. I look around at my peers even here in Mexico and see a shift, like asking for no straw when ordering a michelada.
So focusing on the specific energy usage of dryers begins to sound near-sighted. Nobody suggested that dryers alone cause all waste.
PS: For manufactured products cost is often a reasonable first approximation of environmental impact. When you get 300 paper plates for 2 cents each they really can't take many resources to manufacture. Further, by ending up in a landfill they actually act as a carbon sink.
Washing a few dishes by hand just takes a moment.

That's not true of modern front-load washers. At my old (UK) flat we had an old Beko front-loading clunker. It worked perfectly well but was very noisy and took a long time (not 4 hours though! maybe 1.5 - 2 hours).
At my current place we have a much more modern one where a fast/economy cycle takes 36 minutes. It's nice and quiet too.
Edit: here's an example: http://www.lg.com/uk/washing-machines/lg-FH4A8TDN2#
- 60°C full load 297 minutes
- 60°C partial load 244 minutes
- 40°C partial load 239 minutes
I have no idea why it does that.
I have no idea what the difference between the cotton and the mixed load settings is, but I usually do the shorter cycle if I have a lot of loads to do.
And for the comparison to be correct you need to compare an eco mode quick wash - normally a light load.
I'm trying to. The standardized annual power consumption that is advertised on the energy rating is only accurate if you use the default settings for 40 and 60°C cotton cycles. And that is effectively 4 hours at 40°C for a partial load. I saw the advertised "turbowash" cycle, however while it's supposed to be energy efficient, you have to take LG's word for it.
In the US, while models differ in size, if you look at a similar price range and load capacity, you'll see that numbers used for the energy rating are pretty similar (around 100 kWh or less). But, to my knowledge, the default cycles are fairly short. Sadly neither Samsung nor LG seem to publish cycle length in their manuals.
Slow wash cycles are more efficient. Loosening the dirt by soaking means that less agitation is required. Manufacturers cheat the mandatory efficiency tests by making the default cycle very slow, but offering faster cycle settings. My washing machine takes nearly four hours for a standard cotton cycle, but has a "speed perfect" button that reduces the wash time to under an hour. I always use the fast setting.
It is, perhaps, a little deceptive if people believe their machines are more efficient than they really are on the commonly used cycles.
The way to solve this would be to improve the efficiency tests so that they test the efficiency of a fast cycle as well as an economy/long cycle.
I guess if you're setting it running in the morning and then heading out for the day, 4-5 hours isn't a problem. But often I end up doing all the laundry on one day: clothes as well as towels, bed sheets, etc, in multiple loads, and don't want to be waiting around too long for each load to finish...

These cycles take longer. AIUI it's to compensate for reduced temperature (saving the bulk of the energy) and reduced water usage.
None of this is news.
Of course, people used to use actual (chlorine) bleach with laundry more often, rather than colorsafe “bleach”, and chlorine bleach does kill germs, so that's part of what happened.
I've been trying to just use vinegar. Hope it helps.
As for the driers, if your coloured clothes have that whitish undertone that suggests they've been through a good drying in your drier, then I think you're doing it wrong. I was so disappointed how much my clothes would wear out in the American driers that I'd always make sure to only use them on the lowest setting possible, even for jeans and such. Definitely not missing any old non-HE driers; you're not really supposed to kill the bacteria with the heat of the drying anyways, and using hot water is much more efficient for that.
My washer is sitting next to the kitchen sink and I just manually add a huge load of water every time I turn that damn thing on. I installed a faucet with a hose just for that reason.
Most of the washing machine purchasing decisions must be based on the marketing fluff. I don't think there are many publications even on EU level which run and publish comprehensive tests for these machines. Without such objective tests, it is pretty much impossible to base the purchasing decision on hard facts (except those mandated to be reported by EU).
I remember reading that some washing machines actually did not even obey the request to use high temperatures, because the manufacturer had noticed that they can match the EU target for wash efficiency also with lower temperatures. Can't find any reference for this, so take this with a grain of salt.

Cape Town will likely be out of water by July 15.
High efficiency dryers and washers have their place; just maybe not where water is prevalent.
The lack of water meters is a legacy thing. Water companies all over the UK (including the North) are trying to migrate consumers away from unmetered tariffs. For example: https://www.nwl.co.uk/your-home/your-account/considering-a-w...
And in case you think the water companies are just as happy if you're on an unmetered tariff: https://www.chroniclelive.co.uk/news/north-east-news/water-m...
The rainy season is starting, and Cape Town is unlikely to run out of water this year. It was touch-and-go until a few months ago, though, and there's still a risk for next year.
In my experience the newer energy efficent washers/dryers are almost total garbage compared to the older ones. I would love to see this experiment repeated with an older 90's kenmore or whirlpool or really any brand from the 90's or before.
I love the idea of saving energy, and energy efficient laundry sounds like a great idea on the surface, but what I think happened was the government put regulations in place without really considering the actual impact this would have on the quality of the washers/dryers.
