The energy-saving/low water-use appliances I have perform excellently.
Frigidaire FL Washer: uses 13-14 gallons to wash a large load of clothes. No problem with cleaning. I've adjusted to seeing no water in the tub. As long as clothes are cleaned and rinsed and spun dry I just let it do its job. I've given it several tough cleaning tests (you'll recall the mud/oil muck test I posted here a few months ago) and I'll bet it performs as well as or better than any top-loader, vintage or new.
LG 9810 Dishwasher: uses 3.5-5 gallons for a normal load. The machine cleans better than any I've had, including KitchenAid, Whirlpool, Frigidaire and Maytag (the Maytag was the cleaning champ before the LG).
2007 Frigidaire Top-Freezer Refrigerator: uses substantially less energy than even my 2002 Frigidaire refrigerator, with no loss in performance.
Gerber Power-Assist Flushing Toilet: uses 1.6 gallons per flush. Never fails to do its job on one flush.
CFL Bulbs: I switched my entire house over to these about five years ago. Quite by accident, I purchased them all at Home Depot, whose 'house brand' bulbs produce a better quality of light, and achieve full brightness faster than many others (according to subsequent test results in Consumer Reports). Having said that, I believe LED "bulbs" will usurp the CFL, as they use even less energy and will have no mercury/disposal issues. I will concede there are some really awful CFL's out there. My local utility gave each household one to try. It produced a weird greenish light and was quite dim for the first 20 seconds. I returned it, and told them they weren't going to convert anyone with those lousy examples of CFLs.
1994 Geo Prizm LE Sedan: 240,000 miles on it and it still gets 39-41 mpg. on the highway. It's by far the most reliable vehicle I've ever owned. I've saved thousands in repair bills as compared to GM and Ford autos I've owned in the past in addition to fuel savings. (The Geo Prizm is a rebadged Toyota Corolla, for those not familiar with the model.)
I'm sure there are crappy energy saving appliances out there, just as there has always been crappy energy hogging appliances. But to contend that all energy/water saving appliances are inferior in performance is simply not true.
Buy appliances that perform well and save energy/water. I don't understand this knee-jerk reaction against energy savings. Does it feed our egos or make us feel more powerful/dominant to use more energy/fuel/water than is necessary to maintain a comfortable existence? Part of this mentality comes from having had subsidized, cheap energy available to us all our lives. That will change in our lifetimes. There's going to be a very tough, expensive period in the gap between the "tipping point" of fossil fuel reserves and the growth of alternative sources of energy---again, because there's little rush to acquire new technologies when fossil fuels are still relatively inexpensive.
Back to vehicles: Don't forget the automobile lobby has the oil lobby as its ally. Together, they are far more powerful than any appliance lobby could possibly be. As China and India raise their standard of living and thus consume more oil, prices for fossil fuels in this country will rise to heights we've never experienced. There is already talk of $4.50-5.00 gasoline within a couple of years. I can assure you that many people driving a 14-mpg Chevrolet Tahoe will quickly reassess their vehicular needs. On the other hand, when fuel prices climb that high, and wages for workers in Mexico/China/India/Korea increase, some manufacturers may be forced to move their production centers back to the US.
