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."
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.
Smart appliances are a truly dumb idea. What things in your home consume the most power?
Tier 1
Refrigerator.
Stove/Oven/Microwave.
Heating/Cooling.
Dishwasher.
Dryer.
Tier 2
Lighting
Entertainment system.
Hair dryer etc.
Can you wait for off-peak power for any of those? Of those things, what can really be delayed?
The fridge? Not if you dont want you food to spoil.
Stove/Oven. Not if you want to have dinner.
Heating/Cooling. Not if you want to be in your house while you are awake.
Dishwasher. Yes. That one.
Dryer. Maybe, if you are okay with wet clothes sitting around (mold). Not if you have more than one load.
Lighting Not if you want to be in your house while you are awake.
Entertainment system. Not if you want to actually use it.
Hair dryer? No, that's not how it works.
So there was what? Just the dishwasher?
This whole idea sounds like some dumb-ass' PhD topic. Fascinating in theory, doesn't work in reality.
etc, I don't want it done via taking away rights and freedoms and forcing people to not use electronic devices until off-peak hours. I also don't want it done in a way, like cap and trade, that makes energy use so expensive that it costs jobs and forces poor people to go without electricity.
This "Smart Grid" has a way of spying on a home owners (or renters) privacy as well as shutting off devices so that they cannot use them until off-peak hours. Can you imagine your washing and drier being shut off, and you need to get three loads of clothes done, and you are forced to wear dirty clothes until the washer and drier can be turned back on. Not only that but sweating it out during the summer when the A/C is turned off by the grid and possibly dying of heat stroke and freezing to death in the winter when the heater is forced off until it turns back on during non-peak hours. I got a feeling there will be a lot of death by the smart grid lawsuits if this thing passes.
Remember, Slashdot does not have a -1 disagree moderation, and no, troll, flamebait, and overrated are not substitutes.
I don't welcome greater government oversight in my private life but I do welcome a more refined two way grid because it may facilitate a "nano" economics and the necessary infrastructure. I just made up the term nano economics and may I rot in hell if it catches on as yet another catch phrase but the idea of individuals and small groups having the means necessary to incorporate into larger entities and supply small quantities of resources for exchange over a grid or in a larger project has many attractive features. Recently /. ran a story on music indies being under fire from large corporations trying to corner markets. A sort of nano economics could have positive benefits from small business startups to undermining unconscionable copyright laws. One of the things missing is a government interface such as might develop from managing power grids at the micro level and burgeoning into a nests set of systems that would allow for a broader array of nano economic possibilities. Some developing countries have experimented with micro banking wherein community members pool small sums of monies to help startups get going. I think a nano economic revolution is available via the current technology but will require the necessary government infrastructure and a shift in thinking and practise on the part of the public. Perhaps mature, industrial countries with the requisite resources and an educated working class could bootstrap such a micro revolution.

I think the biggest problem is that all these devices are advertised as smart first, appliances second. They focus so much on the benefits of being able to access the "smart grid" or whatever, they don't do enough to tell the consumer that the appliances are good in their own right. I think if they make quality appliances with these features, market them as quality that also has "smart capabilities," they would probably sell better.
I mean, sure, it's awesome that when my local power company rolls out peak and off-peak rates that my appliances can tell me when it's more expensive to use them, but I want them to be good appliances first. I want them to be efficient in the first place so I don't have to manage my usage by the hour. I already do enough to keep my appliance usage to a minimum to save money; I don't want to also manage when that minimum occurs.
"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?
As far as I can see, this whole smart-grid concept is being sold as a money saving move when it's really about convincing the citizenry to freely accept rationing, even ask for it. The whole basis for the smart-grid is the notion that we cannot or more correctly, should not generate more electricity. If this is allowed to continue, we will all be forced to accept a lower standard of living.
why do you need your air conditioner on at all when you're on vacation?
To keep your home's server rack cool. This is /. isn't it?
Ubik, I think, was set in a world were even the doors were 'smart' so you had to pay a toll every time you went in and out of your apartment... unless, of course, you had a screwdriver handy. Somehow I doubt that any 'consumer' really wants to live in a world like that.
That the "Smart Appliance/grid" proposals seem to be skipping the simple, obvious, and substantially less problematic option in favor of a complex mess of remote control crap.
Fact is, the farther from base load you go, the more the marginal unit of electricity costs. No getting around that, barring amazing advances in generation or storage technology. Because of that, there are clear efficiencies to be had if load that can be moved off-peak is moved off peak. Unfortunately, the "smart grid/appliance" setups that involve utilities remote controlling your stuff are invasive, complex, and downright paternalistic.
Far better would be a simple price signalling mechanism. The electricity company's meter would report, every period(could be simple "off peak"/"on peak" could be each hour, could be each minute, could be each second, doesn't matter in principle) the cost of a unit of electricity consumed during that period and the value of a unit of electricity sent back to the grid during that period. The reporting would be via a standardized protocol on a standardized header on the unit and/or over the powerline and/or a standard wireless mechanism(again, details aren't wildly important).
That reporting would be all. If I wished to adjust my usage to save money, I could purchase appliances capable of interpreting the standard electricity price information(either built in to the appliance, or in the form of a smart breaker box, that could turn on and off power to specific outlets). I could then program the device or devices to respond as I wished to price signals("AC: NEVER go above 80c, go to 68 if price is less than 10cents, go to 70 if price is between 10 and 15 cents" "Dishwasher: do not run if price is greater than 10 cents, unless override button is pressed").
This scheme would have three major virtues: First, it would avoid the invasiveness of having somebody else control your home systems. Second, it would allow each individual to set his own priorities on the value of various uses of electricity, rather than a one-size-fits-all approach. Third, it would allow unconstrained innovation/optimization by device manufacturers in what options to provide and how granular to be.
For instance, a computer could be set to manipulate its own ACPI settings according to the current price level, wifi devices could trade off between throughput, range, and power in response, AC could adjust target temperature, etc. Devices that store or generate electricity on site would know their own costs of operation, and only operate when economically viable. If a utility, for whatever reason, was facing capacity problems, they could simply raise the price of a unit sent back to the grid, to encourage local generators to start up.
Obviously, serious configuration of the details in each device would be substantially beyond the interests(and quite possibly the capacity) of a lot of people. For them, manufacturers could simply provide a suitably small set of sane default options(probably the same ones that a one-size-fits-all policy would apply across the board). For complex programmable devices like computers and game consoles, interested organizations could even distribute suggested settings packages over the internet.
I live in Central Florida and we had the "great" box in the garage that controlled A/C, Water-heater and Pool. For a ~$8 saving per month, the power company would send a signal over the wire to turn-off these items to save power on grid.
I had small children that were are home and temperature in house soared to 95+ for hours on end. The A/C cycle time was to at most 80 degrees. We were running the system for 4hrs or more at night to bring the temp back to ~75 degrees.
The pool was constantly green, causing more shock treatments and forcing us to run the filtering all night to catch up.
Finally, had to power company "cut" the connection. Lowered my power bill, 20% since the internal systems did not have catch up.
Also around that time, the power company was also cross connecting the meter with cable. The reason was to improve this control and let them read meter from afar. I had that removed when the power company would not warrant any damage that joining these isolated systems could cause since I was running multiple surge protectors. Lighting strikes were common, one hit the tree behind my neighbor's house taking out the power to back of the house (fried wires). Power Company tired to get me to leave installed after they offered upgrade my wiring to "full house" surge protecting - If I paid them $1000 to install it.
Good luck with that. In Ontario, they've already mandated smart meters by law. Here come higher hydro rates too, we're about to get screwed and they said that it will net us lower rates. They did the same in Quebec, rates jumped by 15-35%. Big shock, there is such a glut in raw hydro here, that they're actually shutting down one of our nuclear reactors for several weeks because of excess power.
Annoying as all piss. There was no input on this, bloody statists.
Om, nomnomnom...
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/note-on-UK-grid-CO2-intensity-variations.html
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).
