Consumers May Find Smart Appliances a Dumb Idea

theodp writes "As GE readies appliances that communicate with smart meters in the hope of taking advantage of cheaper electricity rates, CNet asks a big question: Are consumers ready for the smart grid? Right now, most utilities only offer a flat rate, not time-of-use pricing, so the example of a drier that reacts to a 'price signal' about peak rates by keeping one's clothes wet until a more affordable time is pretty much a fantasy. And longer-term, a big question is whether consumers will want to deal with the hassle of optimizing household appliance energy usage themselves, or be willing to relinquish monitoring and control to utility companies — with a concomitant loss of privacy. After all, losing one's copy of 1984 is one thing — losing one's lights and refrigerator is another thing altogether."

  1. How long will peak rates be around for? by DigitAl56K · · Score: 5, Interesting

    As a single guy (rare for Slashdot, I know..) I don't use much energy at home during the day because surprise surprise I'm out at work. On the other hand, I'm sure there are many people who have families where one adult is home part of the day and probably takes care of cleaning, laundry, etc. during that time, probably watches TV and/or uses the computer, has kids to entertain, needs air conditioning in the summer, heating in the winter, etc. It doesn't seem like smart electronics are going to substantially change these behaviors. Great, the dryer wants to wait until off-peak to dry my clothes, but I have 3 loads of laundry to get done..

    What may change things is something that we've discussed here several times: Electric cars that have the ability to return electricity to the grid during times of high demand. Hopefully this or other means of localized power storage will reduce the need for "peak" pricing in future. Hopefully devices will also consume less power in future. For example, if you're spending time online with your notebook you aren't drawing anywhere near the 100-200w you would if you were using a desktop system (my Eee 1000HE netbook draws 9-12 watts).

    I would rather see us find ways to better match power availability to demand instead of a short-lived period of doing the inverse. Electric cars are a great way to do so because it's a natural leverage of developments in our lives that are already taking place with widespread support.

      Tankless water heaters only heat the water when you need it.

      Your refrigerator could apply a colder temperature before peak usage period, to reduce the amount of cooling that should be needed during the peak time, or apply other measures "in anticipation" of approaching peak usage period..

      Australia has had off-peak rates at night for decades, most people use it for their hot-water service.

    "able to tell your home that you are going on vacation. Your hot water heater can chill down and take a break, and your air conditioner can work less hard (keep the house at 76 degrees F, say, instead of 70 (24 Celsius instead of 21)."

    When I was a kid and we were going to go on vacation my mother would turn down the thermostat (you had to leave the furnace on in the winter so the pipes didn't freeze. In the summer the furnace was off anyway, pilot light out), and unplug the TV etc. so a surge couldn't hurt anything. Dad would turn off the hot water heater (which meant when you got home you had to wait for hot water). No need for an "energy manager." Have people gotten that lazy?

    PS: why do you need your air conditioner on at all when you're on vacation?

  3. Selfish/ignorant nonsense by DamonHD · · Score: 5, Insightful

    I love the entirely ignorant and self-absorbed "I'm alright Jack" and "Keep the Gubmint Outta My Fridge" and "I want the right to burn dioxins on my own lawn" comments.

    Goodness.

    For a start there's at least two sorts of appliance smartness that are useful.

    1) For example, load-shifting use until there is low demand on the gird. Sometimes that electricity can be practically free (or even negative price) and reduces infrastructure costs (hardware built to cope with a smaller peak) and reduces use of often dirty and expensive 'peaking' plant. You don't have to subscribe to Climate Change to see this as a good idea. And yes, for the average family home the main candidates are the dishwasher and the washing machine. Just avoiding running your dishwasher right after dinner (until you go to bed or optimally ~3am) in the UK right now saves circa 100g CO2 emissions each time for no inconvenience at all usually:

    http://www.earth.org.uk/_gridCarbonIntensityGB.html

    And indeed right now since the highs and the lows are at fairly fixed times then a simple timer will do a good job: not much Big Brother smartness there.

    But as more intermittent power such as wind comes on line, those 'excess power available' moments will be less predictable. A really smart dishwasher lets you run it just when you want to, but if you're not in a hurry you could set it for "make sure it's done by the morning, but try to pick the time for minimum costs/emissions". I already do this in my house.

    2) Balancing the grid cycle by cycle is a separate issue. In the UK fridge/freezers alone correspond to a base load of ~2GW. If a 'smart' fridge notes that the power frequency has dropped because the grid is struggling then it can postpone restarting the compressor so as to stay within normal temperature limits but coast a little while on its store of 'cool'. It might also suspend any auto-defrost for example. That helps keep the house lights on (yours and everybody else's) without spoiling your butter or denying you any rights at all. Last year we had a major nuke trip out in the UK and 500,000 people across the UK were 'load shed' and lost supply entirely. If all the fridges had been smart they may well have stayed on line without anyone noticing.

    Hyperventilating about "communists" turning off the lights and freezer is so childish I find again /. posts failing to meet the IQ levels that I assumed were necessary to type. %-P

    This is not to deny that such a mechanism can be royally f**ked up by individual governments and utilities, but going purple in the face while ignoring that the alternatives may well include more blackouts or higher prices, even ignoring climate-change issues, doesn't help.

    Note: I already do some of this at home. I still haven't voted communist (though they may have had a local candidate here for the last elections).
