I'd like consumers to demand water- and energy-efficient appliances of manufacturers, but that isn't always realistic since there isn't a common platform for us to research and demand those changes. It makes sense that a government agency, like the Department Of Energy, which can study the possibilities and then implement those changes, acts as the catalyst. We have more efficient appliances, cars, and homes as a result.
Is that system of implementing change perfect? Of course not. Manufacturers in a free market system will always opt to meet the challenges of increased efficiency in ways that are the least expensive for themselves. The cheapest way for manufacturers to meet energy-use mandates in washing machines is to lower water temperatures and water levels. Front-loading washers, by the nature of how they work, have proved themselves far more capable of adapting to decreased water and energy usage while still providing excellent results. This is why it has been the dominant format in many parts of the world for decades.
Unfortunately, top-loaders are not as well-suited to decreased water usage. HE top-loaders, often using new (or at least new to us) methods of agitation like impellers have tried, with wildly mixed results, to meet those challenges.
The tipping point of mandates for me: Not being allowed the choice to use truly hot water. As I've said before, I have no problem with machines defaulting to energy-saving settings. I have a problem when a washer dictates that I'm not allowed to use water hotter than 100 (or so) degrees under any circumstances--especially if that washer is a modern front-loader, which uses so little water to begin with.
How do I know if I'm using more resources than are needed?
Washer A:
<span style="white-space: pre;"> </span>> cleans a 12-lb. load effectively using 35-45 gallons of water (about 8 gallons of hot water if using the "warm" setting)
<span style="white-space: pre;"> </span>> leaves enough moisture in fabrics to require 45-50 minutes of time in dryer
<span style="white-space: pre;"> </span>> has a 30-40 minute average cycle time
Washer B:
<span style="white-space: pre;"> </span>> cleans a 12-lb. load effectively using 13-17 gallons of water (about 2-3 gallons of hot water)
<span style="white-space: pre;"> </span>> leaves less moisture in fabrics; requires 30-40 minutes of time in dryer
<span style="white-space: pre;"> </span>> is gentler to fabrics
<span style="white-space: pre;"> </span>> has a 45-75 minute average cycle time
If I choose Washer A, then I am also choosing to use more natural resources than are needed to get the job done. I realize that one's time is also a resource of sorts, but I work all day and often have rehearsals, meetings, or performances in the evening. Still, I manage to get 7 or 8 loads of laundry done in a week without a problem, even though my washer of choice has a longer cycle time. Unless I'm hanging successive loads on a clothesline, a 30-minute wash cycle isn't going to save a lot of time if the dry cycle takes 45-60 minutes.
HAVING SAID ALL THAT...I just purchased a traditional top-loading washer that requires more water and energy to operate than does my front-loader. I enjoy it more for the nostalgia factor than anything else. I see it as a wonderful artifact. It does a great--but not better--job of cleaning a load of fabrics compared to my front-loader. As the novelty of using the Speed Queen abates, I will use it less and less, because the front-loader does the same job using fewer resources, and it treats fabrics more gently. It also handles big, bulky items like queen-sized bed comforters more adeptly. To me, that's just common sense.
