Standby Electronics a Waste?

gnunick writes to tell us BBC News is reporting that UK citizens waste quite a bit of electricity each year by leaving electronic gadgets on standby or charging. Critics are arguing that standby mode on electronics are completely unnecessary and should be removed for a number of reasons. From the article: "To put it another way, the entire population of Glasgow could fly to New York and back again and the resulting emissions would still be less than that from devices left in sleep mode."

      That's for sure. And there are even more devices where it isn't even standby - they're wasting power when "off" while providing no added functionality at all.

      Anything with an A.C. adaptor feeding it is generally wasting power all of the time it is off. Switching designs help, but most adaptors have transformer core losses being fed all the time. I've found the same thing internally in some devices. Looking around the house, I found that my soldering stations and a table radio had the power switches wired after the transformer. Some things that have transformers or whole power supplies live all the time include doorbells, thermostats, garage door openers, VCRs, CD/DVD players, cable/satellite boxes, printers, and cable/DSL/dialup modems. I remember the shock at discovering that my old electric toothbrush had a stand with a field coil powered all the time. The coil was the powered portion of a motor to wind a spring in the hand-held unit.

      Contrary to what the article says, cable boxes could be designed in a way where they could be shut down. The boxes could designed to handle revalidation only when a box is on. Data when off could be retained by a small amount of CMOS memory and a capacitor, or by using flash memory. Switching on the main power supply could be done by passing power for devices it feeds signal to through the box, and sensing load current to trigger starting the power supply. I don't think we should be paying for energy just to make someone's DRM work.

      Devices with timers could be designed to run from charged capacitors. Small half-Farad capacitors are available. Some devices use lithium batteries, but I prefer to avoid those since they're toxic waste later.
      I reduced the power consumption of an old L.E.D. digital alarm clock from 8 Watts to 1.2 Watts by replacing the transformer with a capacitive voltage divider, and eliminating the series-pass regulator by using S.C.R.s in place of two of the diodes in the bridge rectifier and controlling those. That savings was enough to power a bedroom color t.v. 2 hours a day.

      I'd like to see someone design a cordless phone that was efficient enough to get by with powering the base unit from the phone line. They could at least use a switching supply for the base unit. Few people really need to have their microwave ovens programmed in advance to come on at a certain time. For years I kept my old microwave with a rotary knob mechanical timer. That oven didn't use any power when off. Most U.P.S.es could be designed to use less power once the battery is charged - they'd probably get better battery life too.

      Devices that are powered all the time are at a greater risk of being fried by line surges.

      On my old computer I wired an outlet box to the switched monitor power outlet. Then things like my modem and amplified speakers would have the power cut when the machine was off. If the machine had been designed to control that outlet in sleep mode, consumption could be cut even more. Having those items powered from the computers switching supply instead of transformers would save even more.

      Sometimes when shopping I ask salespeople how many kilowatt hours per year a product uses when turned off. It's entertaining to see the weird looks I get. If a few more of us asked suppliers about these things it might speed design changes. Designers need to be educated about the need for reduced consumption also. Sometimes it seems like many don't worry about it except when too much heat is produced.

      Consumers tend not to think of low power leeches as costing anything, but it adds up over the life of a product.

      The amount of energy consumed by the first coil in the transformer (the one plugged into the wall) is proportional to the amount of energy consumed by the second coil (the one with the switch in it). This is because a coil stores energy like a capacitor. There is a finite amount of energy that the coil can store, so when that amount of energy has been stored, the coil will no longer draw a current (this works very much like a switch). When the stored energy is used, (for example, when a current is induced in the second coil), the coil will draw enough of a current to replace it. So, when you turn off the switch on the second coil, the first coil will cease to draw a current (of course, a small amount of energy will be dissapated in the form of heat, since there is no such thing as an ideal conductor). This is why your power company can put several step-down transformers in the power grid as electricity finds it's way from the generation plants to your house, and yet the load on the generation plants varies based upon the amount of power used, not by the number of transformers in the grid.

      This is also a good concept to remember in the context of this discussion. A CRT uses a very large electro-magnetic coil. When you first power this coil up, it draws an enormous current (if your house is wired poorly, you will see your lights dim). That energy is not dissipated, however; rather, it is stored in the coil as an electromagnetic field. As that field is used to control the electron ray that generates the image on the screen, the electromagnetic field is consumed, and the coil draws a current (much smaller than the initial current) in order to replace it. When the CRT goes into standby, that electromagnetic field is no longer being consumed, and the only current being drawn represents the energy being dissipated as heat -- the more efficient the design, the lower this current will be. Remember, there is a large amount of energy stored in the coil, and a small amount of energy being consumed. When you switch off the CRT, the circuit of which the coil is a part is broken. When this circuit is broken, the entire electromagnetic field will be dissipated at once as an electromagnetic pulse, wasting all of the energy that it was storing. So, depending on how often you use it, standby may waste less energy that repetedly turning the device on and then off again.

Once they're heated up, you can start using them pretty much immediately.

The efficiency of that transfer is far below 50 %. Only if your house is electrically heated, without employing a phase-change heat exchange (a reversed fridge for the air leaving the building, making the outside a little cooler) it's equivalent and one can still argue about how to achieve optimum airflow.

      As a Norwegian living in England, I have to agree... Here in the UK I think it's largely down to mild winters. Insulation is practically non-existent in older buildings here (most new builds seems to be better, thankfully) - just a thin wooden floor with huge cracks and 20 cm or so of air separating you from the ground is quite common.

      Before I'd moved to the UK I hadn't even seen buildings built like that except in museums.

      The lofts are usually equally bad - huge parts of the building mass still have completely uninsulated lofts (though admittedly there is a push to change that, with government grants often available to offset the cost of insulation) and huge cracks everywhere.

      I guess it's a cost thing combined with the fact that the climate lets them get away with it (for those who haven't lived anywhere COLD: Imagine having your walls full of moisture. Then imagine that water freezing and expanding. Now imagine the cracks developing after a few years of that happening on a regular basis...). But it annoys the hell out of me when I see bathrooms built in a way that'll give the people on the floor below a nice shower if you get the floor a little bit wet.

      British builders, though, seems to be in a league of their own, and that is not a compliment. I've never ever had to deal with such a bunch of incompetent twits. Just got to love how they think that it's perfectly fine to just keep pumping more silicone into a flat roof if it's leaking, instead of actually trying to find a fix the massive leaks in the top coating of the roof. Because apparently that's too much work for them.

      The lack of a proper certification system and a proper education is really a problem - to the point where it's not uncommon for people here to hire in German builders to get things done properly even with the extra costs (for larger jobs they'll easily pay for themselves by actually doing things properly, and without the massive delays British builders seems to take great pride in...).

      Really, most new construction in the U.S. is quite energy efficient. Newer houses have greater problems from indoor pollution than from energy inefficiency. The problem in my area of the U.S. is historical preservation. The houses in my neighborhood were built in the late 1800's/early 1900's. They were not intended to be 100 year homes, but they have lasted that long. Now it is against the local codes to make any modifications without undergoing a three-month long historical review process that will approve any modifications.

This makes even the minor task of replacing a hot water heater with an on-demand water heater an onerous process.

      btw, perimeter heating is the label applied to the practice of providing the heat input close the to sources of loss (walls, windows, doors) to avoid aggressive drafts inside the structure.

And, oddly enough, as of five years ago when I finished my mech. eng. degree, the natural gas compressor stations were one of the five largest polluters in the US! That is due to the fact that they were all installed so long ago, before the major emissions breakthroughs of the past 15~20 years. A lot of big money is being made by producing retrofit control packages using pretty cool technology (hydraulic or electric intake valves, for instance) to reduce emissions and increase combustion efficiency.

      Here is one way to think about this statement: If the local electricty is generated by burning oil/propane/gas, then by the time it reaches your TV set or computer, only about 40 percent at best of the original energy is left, the rest is dissapated in the turbines, the smokestacks, wastewater, and resistance losses in the transformers and power lines along the way. Modern oil or gas furnaces are 90% efficient or better, and just about anything less than 30 years old is 80 percent efficient if it has been maintained properly. Even if the local utility gets its boiler fuel at a bulk discount, it will cost them at least twice as much to generate the electrical energy as it would to get that same amount of heat by burning same fuel directly in your own furnace.

      The relative economics of different types of energy sources can skew these calculations. In Central Maryland, electrical rates are relatively low (about 7 cents/Kwh) due to the fact that BGE generates much of its electricity with nuclear, coal, and hydroelectric sources. It is almost as cheap to turn on the electric stove than it is to run the gas furnace this winter. In other areas, electricity is running nearly twice the cost here, due to the fact that the utilities in those areas burn mostly oil and gas to generate their electricity.

      Of course, generating heat by leaving electronics, as well as electric lights and appliances on in the summertime is doubly expensive. You not only pay for the electricity it takes to keep these things powered up, but you also pay the additional cost for the air conditioning to remove the excess heat from your living space.

    17. Re:Believe it or not, Oil companies are to blame. by anthony_dipierro · · Score: 1

      I know you were being sarcastic, but you are almost correct. The real reason they invaded iraq was money. Oil is just the means of making money. Essentially, the war with iraq was nothing more than a business venture to Bush/Cheney. So, using logic, we can derive that lowering the price of oil was never on the agenda. I think all bush/cheney care about is money.

      That's a reasonable explanation, but the way Bush would make money off oil is for the price of oil to go up, not down. In that sense, I think it's misleading to say the war was fought over oil. (I did, however say from the beginning that "he motive clearly wasn't oil either, unless maybe you think Cheney wanted the price of oil to go up to boost his Halliburton stock.")

      So when they get more oil, why would they want to keep the profit margins the same by making it cheaper?

      The thing is, "they" aren't going to get more oil.

      "Everyone is already paying $x.xx, they'll probably continue to pay that much, even though we've now got a larger supply. This way we make more money."

      Oil companies make more money when supply is smaller. This is obvious to anyone who studies either economics or history.

      No. i observed events which, when considered logically, point to the fact that he invaded iraq to make money (indirectly) from selling oil.

      Quite indirectly. But yeah, I can agree with that to some extent.

      And it wasn't tough to come to this conclusion. Mainly because of the lack of any other viable reason to invade iraq.

      There are lots of viable reasons to invade Iraq. Saddam wasn't exactly the friendliest guy, you know. In fact, we've been in an ongoing conflict with Iraq at least since they invaded Kuwait, including through the entire time Bill Clinton was in office. You don't think Clinton was enforcing the no-fly zones because of oil, do you?

      When the only possible righteous reason can be ruled out because it applied to many other countries with greater urgency, you know something is up.

      No, you don't, because having a reason to want to invade a country isn't enough. You have to have a certain level of international support, and a certain level of assurance of victory. When Bush went into Iraq the US had all three of those things, at least in the mind of Bush (in hindsight, as well as in the minds of many including myself he didn't have enough of an assurance of easy victory, but I think it's clear Bush *thought* he was going to win the war fairly easily).

      With what other countries do we have all these things? I'd say none. We're not going to invade China. We already lost the war with South Korea. We'd face a tough battle of questionable international support against Iran. No, I don't think there are any other countries it makes even remote sense to invade (maybe Iran could be argued, though I'd disagree, and if we had really won the war in Iraq as quickly as Bush had hoped we might be losing the war in Iran right now).

      Bush was coming off a relatively successful war in Afghanistan with tons of international support. He convinced roughly half the relevant nations to support a war in Iraq, and he calculated quite correctly that the other nations wouldn't do much other than hem and haw about it. It seems to me, and actually all the evidence that has come out suggests, that he thought the war would be quite quick and relatively casualty free.

      But maybe it's better if I just put it this way: why did Bush invade Iraq for oil when there are many other countries which have more oil than Iraq? Why didn't we invade Canada, or Mexico, or Nigeria, or Venezuela, or Saudi Arabia? Hell, there are plenty of reasons to invade Saudi Arabia that both are oil and non-oil related. Reasons aren't enough.

      Or more simply you use a capacitor and a relay. While the tv is operating the capacitor remains charged. When switched into standby mode, the capacitor will keep the relay closed for a while allowing power to the transformer and the infra red receiver. After being in standby for too long (an hour or two) the capacitor will have discharged and the relay pops open cutting the power on the mains side. Pressing the button on the tv will momentarily reconnect the power (not via the relay) and put the tv back into 'on' mode - the current flowing again will close the relay and recharge the capacitor.

    I have a CRT television set (with a standby button), a VHS recorder (with a standby button), a DVD player (with a standby button), and a digital satellite set-top box (with a standby button). Only one has a real mechanical, circuit-breaking, power switch easily available (the TV).

    In order to even turn all the devices into standby, I need to fumble for four different remote controls, else they all end up heating the living room when nobody is in there. Typically, the TV is the only thing that gets put into standby.

    Given that the VHS has auto-set up and can recover from a power outage (save for timer recording, which many people don't use), I guess it might make some sense to hook them up to one of those master-slave power bars, whereby you set it up so that when the TV stops drawing full current, the other sockets are switched OFF.

    The digital satellite set-top box has a few issues with losing power (it loses EPG reminders, and defaults to some silly promotional channel, which I guess is mostly due to design by BSkyB).

    Here's another thought. Duplicate circuitry. All of those devices have DC transformers. The digital satellite set-top box has MPEG2 decoders, as does the DVD player, yet they are never used at the same time, but the circuitry is probably receiving their full power budget at all times. Likewise, the TV set and DVD player both have audio amplifiers, yet I've never used the speaker outputs on the DVD player.

    If I had one well-designed appliance that had the screen, a DVD transport, a VHS transport (yes, they are still used), and an integral digital satellite decoder, it could use far less power overall. The problem there is obsolecence. In order to get that, I need to either sell, give away, or recycle the existing equipment, which uses energy. It also means that if I decide that High Definition television is going to be good, I'd have to discard the lot of it and replace it, but with something with a HD-DVD, or blue ray mechanism? turns into diminishing returns.

    If all such equipment responded to a standard "enter standby" remote control code, then I bet more equipment would be going into standby rather than remaining on full-power. If they could all go into a mode where they use less than a watt in standby, all the better.

    Example: I drive a car with a small engine and a catalytic convertor. It therefore is (relatively) environmentally friendly, no? Except my previous car had a larger engine yet consistently achieved better fuel efficiency. I suspect the larger engine wasn't being thrashed just to get to 30mph is much of the issue - an engine being driven hard is never as efficient as one idling.

    A catalytic converter doesn't make your car more fuel efficient. It reduces harmful emissions such as carbon monoxide. Therefore it is environmentally friendly, especially to people, animals who have to breath the air and plants who don't have to deal with "acid rain". Catalytic converters undoubtedly save tens of thousands of lives. It doesn't reduce all emissions though and pumps out CO2 which while more "benign" than some emissions is still a greenhouse gas.

    Besides which, it is your own damned fault if your new vehicle is less fuel efficient than your old one. You should have read the specs. As a general rule, smaller engine size does equate to better fuel economy but there is obviously going to be overlap.

    I have read a lot of times in Slashdot that people say "Linux PC's do not need to be turned off", but I disagree, because there is no way I will leave my computer turned on 24/7. That is why I need a fast "turn on" button for those devices. This may sound like a bit off topic rant but, I have never been able to configure properly (of course I do not care reading howtos and modifying .conf files) any Linux distro (I have used Mandriva 2006 ppack or Fedora Core 4) to enable hibernation mode, I do not know how difficult is it to have just a "Hibernate" button like MS Windows, so for me it means each time I finish working I turn off my computer (in fact, I just press the power button, while MSWindows goes to hibernation mode, any Linux distro will kill all the daemons and halt/power off).

    ..... when vacuum-tube valves were all there were, "Standby" was a power mode on a well-built stage amplifier. This provided power only to the heater filaments; the HT was disconnected. The idea was simply to allow the amps to warm up without any danger to the speakers {or an unlucky roadie replacing a defective valve}.

    Modern appliances with a remote control need to draw just enough power to run the sensor and decoding circuitry -- otherwise they would invariably have to be switched on at the wall socket. And since nobody has enough wall sockets, everyone uses multi-way extension leads; but extension leads rarely have individual switches like wall sockets.

    Also, even modern appliances without remote controls tend to have the on-off switch in the secondary circuit of the power transformer. This seems to be something to do with a general reluctance of manufacturers to touch mains. In an ideal world, this would not matter; but in this real world, copper is not a perfect conductor and steel loses its magnetism. So a transformer is not 100% efficient {although it's about the closest anyone's ever built}. By the Principle of Equivalence, we can represent all the losses as a simple resistor in parallel with the primary winding.

    Switched-mode power supplies are becoming more common {laptops, and even most telephones except Nokia, use them for their rechargers}. The basic principle of a switched mode supply is that you rectify the incoming mains to DC; then use a high-power oscillator to turn it back into AC but at a much higher frequency, typically in the 25-50kHz range {you could go even higher but LW radio starts around 150kHz and you have to be careful to avoid interference} which can then be passed through a physically smaller transformer, as the current spends less time flowing in any one direction so the core can be smaller {every iron atom is like a miniature compass needle which tries to align itself with an externally-applied magnetic field, which in the case of a transformer is imposed by the current applied to the primary and opposed by the current drawn from the secondary; when all the "needles" are aligned in the same direction, the core is said to be saturated and the winding is now behaving as a resistor which is not what you want. At 50Hz the current flows for 10ms in one direction, then 10ms in the other; at 25kHz it flows for only 20us in each direction}. In an SMPS it is mainly the leakage current of the input smoothing capacitor which determines the wastefulness.

    If Standby mode is not going away {and it isn't} then the best we can hope for is to ensure through regulation that new appliances are wasting as little power as possible in Standby. And while we're making legislation for new appliances, this would be an ideal time to consider a few other factors; such as minimum standards for product lifetime {I still feel inclined to say "forever" would be an acceptable minimum}, field maintainability, manufacturer responsibility for end-of-life recycling, and whether working standards in the country of manufacture would be acceptable in the destination country.

On a wall wart, that is typically done through some form of diode bridge with a capacitor in there to level off the power.

      Most wall warts are incredibly inefficient (Popular Electronics once did an article on this subject some years ago, and found that they were somewhere in the 50-70% range), and they are consuming power even when the device they power is off or even disconnected.

Diodes that don't rectify properly {even the difference between 50Hz and 60Hz is noticeable with some of the two-terminal devices laughingly described as "diodes" by some Far Eastern manufacturers} and capacitors that leak both contribute to inefficiency. OTOH, running an appliance from even the least-efficient plug-in PSU you can find is still a hell of a lot greener than running it on disposable batteries.

      Also as I said before, part of the problem is that most appliances are not plugged directly into the wall, where each socket always has its own separate on-off switch, but run from an extension lead; and extension leads do not usually have a separate switch for each socket. I don't know why this should be the case, apart from sheer cheapness.

      As for the 7805, that is just a series regulator: a zener diode acting as a voltage reference, and a transistor in emitter-follower mode amplifying the current. The excess energy gets turned into heat. If you feed it with 13.5V and try to draw 150mA, it will drop 8.5V at 150mA, giving over a watt of heat dissipation. In general, the efficiency of such devices = (output voltage / supply voltage) * 100%. There are better devices available. These use a slightly different form of SMPS, in which a capacitor is partly-charged through an inductor to limit the current; this time, the transistor is switched hard off and on, so the only resistive loss is due to the parasitic resistance of the inductor. Unfortunately, they aren't simple drop-in replacements, because the inductor isn't something that can be built on-chip.

      Circuit breakers are there to protect the building's permanent wiring. Plug fuses are there to protect the appliance's flexible cable. Another good thing about our mains plugs is the way the cable exits at 90 degrees to the pins, meaning you have to hold the plug when withdrawing it -- pulling on the cable just tightens it! On the downside, it does mean that they can lie on their backs, pins up in the air, just waiting to spike an unwary bare foot. The purpose of the switch on the socket is to ensure that no current is flowing through the pins of the plug at the moment when they are withdrawn from the socket, otherwise there is a chance of arcing occurring. The live and neutral pins are half-sleeved, and the socket is designed so that the plug will have disengaged completely from the socket before any metal is exposed -- even if you try to use some kind of blade to prise the plug out of the socket, you will only ever catch the protective insulation until the pins are out of contact.

      Every socket outlet in the UK can supply up to 13 amperes at 230V, giving a nominal 3kW. All the socket outlets on each floor of a house are connected together in what is called a "ring main" -- parallel connection with two connections to the consumer unit {fuse box}, one from each end of the daisy chain -- and served by a 30 amp fuse or trip switch. There are two parallel pathways to each socket outlet, so the permanent cable can be a lighter grade {2.5mm2 as opposed to 4.0mm2} since it is effectively doubled-up.

      The fact of there being a 30A fuse at the consumer unit means that if any appliance develops a short-circuit internally, its flexible supply cable might potentially have to withstand enough current to blow a 30A fuse {and such a beast won't even flinch at anything shy of 60 amperes}. That's a lot of energy and there's a good chance of the 30A fuse not being the weakest link in that circuit. So rather than fit an inordinately thick power lead to each appliance, an extra fuse is fitted in the plugtop. Now, if the appliance develops a fault, its flex only has to withstand enough energy to blow the lower-rated plug fuse {and when the filament bulb in my flatmate's table lamp shines its last and takes out the plug fuse, it won't affect the DVD I'm burning}.

      Also, every UK socket is earthed, and every plug has three pins. The earth pin is longer than the live {phase} and neutral, so as to mate first, and is required to be present because it operates a safety shutter covering the live and neutral apertures on the socket when no plug is present. The only power outlets permitted in bathrooms are shaver sockets, and these must be supplied via an isolating transformer {so either one terminal is safe to touch} rated no more than 20VA, fitted with protective devices and mounted as close as possible to the outlet {means less chance of parasitic coupling undoing the effects of the transformer}.

      In the US, in modern construction each room (as opposed to each floor) will have at least one (and possibly more) 15A/120V circuits. (Maximum draw is therefore 1875W per circuit.) Power outlets are duplex, and there must be one for (at minimum) every 6' of wall space. Rooms where additional load is expected (such as kitchens) will be served by multiple 20A/120V circuits. As in the UK, all outlets are 3-prong, with the longest being ground (earth); however, we don't have the half-non-conductive prongs the way the UK does. We also don't do the double-path wiring. In-wall cable for a 15A/120V circuit is solid #14 AWG (2.08mm2); for a 20A/120V circuit solid #12 AWG (3.31mm2) is used.

      I guess this would also mean that there are many more circuit breakers in modern American construction. Current entrance service in new construction is often 200A/240V split-phase, and the typical 'load center' has room for upwards of 40 circuit breakers. High-current devices such as electric ovens or ranges (cooktops, hobs), dryers, air-conditioners, and water heaters will get dedicated 240V circuits; everything else is either 15A/120V or 20A/120V. The wiring is done in a 'star' pattern radiating out from the breaker panel to the rooms or devices protected by each breaker. While I'm sure that 'dual-rail' wiring would be very useful, it's just not done here, probably because of the costs for the additional wiring for every circuit.

      Bathrooms in the US are required to be equipped with GFCI (Ground-Fault Circuit-Interrupting) outlets (or a GFCI breaker for the dedicated bathroom circuit). I guess full-power is used in bathrooms because people here use their hair-dryers far more in the bathroom than in the bedroom. (The hair dryers sold here also have GFCIs built into their cords or plugs.)

      Bedroom circuits are now required (since 2002) to be equipped with an AFCI (Arc Fault Circuit Interrupter) circuit breaker instead of an ordinary overcurrent breaker.

      As to the UK ring main system -- what happens if one of the two hot paths should open? You wouldn't necessarily know it, because all the outlets would still be getting power from the other path. Since the wire gauge is thinner than would be needed in a star-pattern, wouldn't an overheat and fire be more likely? Or is there some device in the breaker to detect this out-of-balance condition?

This monitors the difference between the current flowing out of the live and the current returning into the neutral, and if the difference is more than a set threshhold {30mA is common} the device trips off -- the idea is that if more current is going out of the live than coming back via the neutral, some of it must be taking an unsanctioned path back to earth. ELCB protection is required for showers {bear in mind that 70 watts will make water flowing at one litre per minute just one degree hotter, so a 7kW shower gives you a choice between a lukewarm trickle or a cold gush} and outdoor circuits; but not on lighting circuits, since we use two-contact, push-and-twist fitting lampholders so the metal part of the bulb is isolated and anyway it requires a deliberate act to mess with a lighting circuit. Having the lights unsafe to touch is considered less hazardous than having them fail suddenly under fault conditions.

      UK power distribution is three-phase; domestic wiring is 230V single-phase. At the substation {which usually serves a whole estate}, the three phases are star-wired with the neutral point earthed. Adjacent houses are on adjacent phases; with the co-operation of both neighbours you could run a three-phase appliance. Power enters on a two-core, steel armoured cable, with the neutral and earth joined together just upstream of the electricity meter and then a 60A or 100A fuse. New consumer units {fuseboxes} usually have space for 12 circuit breakers {6 with ELCB protection and 6 without}, but you will still find older ones with just six wire fuses.
      As to the UK ring main system -- what happens if one of the two hot paths should open? You wouldn't necessarily know it, because all the outlets would still be getting power from the other path. Since the wire gauge is thinner than would be needed in a star-pattern, wouldn't an overheat and fire be more likely? Or is there some device in the breaker to detect this out-of-balance condition?
      Not much would happen, really. Even 2.5mm2 cable doesn't cause enough voltage drop at 30 amps to be a fire hazard {and you'd have to be drawing the full 30A from sockets on the same one of the two now-separate paths}. The condition would go unnoticed for years; there isn't any obvious way to detect it. It's difficult to see how it would be caused in the first place, though, unless someone was doing something deliberate that they shouldn't. The three terminals on the back of the socket faceplate {which carries one or two switched 13A sockets} are each designed to accept 7.5mm2 of wire; this allows for the feed from the fusebox, the return to the fusebox, and an additional "spur" connection for another one faceplate, close to the first {so minimising power loss in the single cable} in case the builder did not put in enough power points.

Actally, I think they drill two holes, one low and one high, and when they see the insulation pasing the top hole they know the cavity has been filled. Because there are studs every 16" or so, they have to do this many times across the wall, but that's not that big a deal.

    They also sometimes use expanding foam insulation instead of flecks/pellets, but the approach is the same.

    At any rate, this is a fairly easy way to insulate old homes without tearing apart all the walls...might work for you.

Fiberglass comes in "batts" and you can never fill a cavity as tightly while maintaining the crutial loft as with blown in. Furthermore, rodents LOVE fiberglass. They will make nests in in anywhere they can and in the process, remove large amounts of insulation. Cellulose dosn't seem to have this problem. Cellulose is also a very good "transition" material since it uses a recycled material.

    Most devices only require a few miliamps or mircroamps in standby to run a clock, maybe a LED and a remotecontrol reciever. Most of these devices need a few amps to run motors, backlights, fans whatever in on mode.

    The manufacturer doesn't have the budget to get a power supply built to meet all the legislative requirements about earthing, coupling to mains (capacitive or resitive), RF interference, safety in failure mode etc. They also have to deal with changing supply voltages and plugs types for different markets.

    It is MUCH cheaper to get an approved plug pack (wall wart) or an equivalent internal module that meets this peak power demand for the target market and not worry about it.

    Historicaly these requirements have been met with transformer based powersupplies that have then been run at nothing like their expected output impedence and so very ineficient drawing quite a lot of their expected peak current even when not driving a load.

    Today it looks like switch mode power supplies are taking over. Many of these chipsets have standby features that can detect load and power up when require only consuming very small currents otherwise. For example my newish nokia charger feels cold so it can't be disipating more than a Watt or two.

    There appears to be a few dual power supplies on the market now. The example here is a new ATX power supply that I think uses a linear regulator to power a few mW for standby (very ineficient but only for very small currents) and leaving the big 400W power supply to only run when it is required. i.e. the 400W doesn't need to be able to run in a mW mode so can be more efficient and it only gets run near its peak efficiency. Newer cases don't have the warm spot near the power supply while they have been in standby where as my old one was quite warm.

    I keep my electronic devices (e.g. TV, Sterio, &al.) plugged in through spare surge-suppressors. When I am not using them, I turn off the switch on the surge-suppressor, effectively cutting all power to the devices. My monthly electric bill is generally less than 1/2 of that of most of my friends/family (and, by implication, so is my [home] electricity consumption).


    Last month, it [my electric bill] was <$25USD.


    Now, granted, I don't do things like sleep with the TV on (and I only watch ~5hrs/week, max), I use 40Watt bulbs in most of the fixtures in my apartment, &c., and I have a gas furnace. On the other hand, my computer has a 400W power supply, a 19" CRT monitor, and is usually on. I have an electric stove, which I use to cook at least one meal (at home) per day, and listen to music, on my surround-sound home entertainment system almost constantly, when at home.


    Right now, only my 'fridge, and microwave are drawing power, at my place.

Something like a PIC microcontroller in a low-speed application (lots of sleep mode usage) should use tens to hundreds of microwatts. Converting AC to DC power is somewhat inefficient (thought it was typically 60-70% efficiency for an ATX power supply at moderate load) and I'm sure using a linear regulator like a 7805 will kill your efficiency numbers.

Maybe you could put a battery in the device, which is only used to power a low-current standby circuit...that might avoid inefficient AC/DC conversion.

Redesigning the standby circuit to be more efficient is probably less useful than redesigning the rest of the circuitry...saving 50% of 2W rather than 5% of 100W isn't useful, unless the device is almost never active. (A computer monitor, say, may be active 40 hours out of a 168 hour week) There may (or may not) be additional costs involved...additional circuitry to reduce power consumption may require more power for manufacturing, or produce more pollution. And still, there are more easy targets for conservation...like incadescent lamps, or construction techniques. Not that doing all of these together doesn't help, but if you've got $1M to spend on public service announcements, you might want to make sure you're making the largest impact with what you have.

I'm not talking about the old greenish/blue-white ones, they're pretty disgusting, but the last few "warm fluorescent" ones I picked up at Home Depot are a lot nicer than the incandescent lights I replaced.

If it was actually all incandescent, not only would I be broke from the power bill, but the room would probably be uncomfortably warm. (And possibly it would be a fire hazard as well.)

    But since installing the CFL bulbs I've noticed I'm just a lot less tired, and less dependent on the weather outside -- it used to be that if it was a really dark, overcast day outside that the room would be noticably more dim; with more lighting I can just close the blinds and have basically the same illumination available as if it was a sunny day outside.

    Interesting post, but mostly wrong.

    While the energy going into a transformer increases with the energy taken from the output, small 50/60 Hz transformers are usually far less efficient than large ones and can't be treated as being ideal. Most of these small transformers will waste several Watts or more even with no load.

    Losses in transformers fall into two major categories, copper losses which increase with load and magnetic (core and leakage) losses which are closer to constant. Small transformers, such as those found in AC adaptors, have relatively high core losses. Using too little core area makes it easier to saturate the core. Using too few of turns on the primary (to save copper and space) results in the primary inductance being low, making the current and flux density fairly high with no load. That higher current flowing through fairly thin (high resistance)wire also results in no-load copper losses being higher than they could be. With many of those small transformers the energy consumed under no-load conditions is nearly as much as it is under full load conditions. These losses are what make most a.c. adaptors warm to the touch even when they're not connected to any load.

    You have your monitor coils mixed up. The deflection coils on c.r.t.s are unrelated to any startup surge. There frequently is another coil that actually has nothing to do with normal monitor operation that does operate at a significant current for a short time, but that doesn't amount to much energy because it is brief. I'm talking about the degaussing coil. Typically it is energized briefly when a monitor or television is turned on cold. The combined effect of heating in a thermistor and use of a voltage-dependent resistor is to run a decaying alternating current through the coil for about 10 seconds. The decaying alternating magnetic field demagnetizes the aperture mask inside the c.r.t. and nearby mounting hardware. It's not unusual to hear a bit of a thud/buzz from the monitor at turn-on due to the field from that coil. If you notice a slight shaking of the image just as the c.r.t first reaches operating temperature, you're seeing the end of the degaussing process. The metal aperture mask just behind the screen inside the c.r.t. has the holes or slots needed to properly restrict the beams from the Red, Green, and Blue electron guns so that each only strikes the phosphor coating for the correct color. A magnetized mask typically causes blotches of switched colors, most often near the edges of the screen. Some monitors have a push button for manual degaussing instead (watch the wild colors and image shaking). That saves a little energy under operating conditions since there is no voltage dropped across a thermistor.

    By having the thermistor in series with the main power to a monitor, it can serve the dual function of powering the degaussing coil and reducing the amplitude (but extending in duration) of the startup surge current flowing into the capacitors. That reduces the surge current extending the life of the power switch, and allows use of a smaller fuse which would give better protection against fault conditions. Turning a monitor off and on quickly won't degauss the c.r.t. again because the thermistor takes time to cool off. It has nothing do do with energy storage in coils. From an energy consumption standpoint, the startup surge and energy stored in the capacitors is unimportant. The only time it really matters is when a monitor is running from a U.P.S. If the startup surge is too high, a U.P.S. may shut down when the monitor is turned on. The same U.P.S. might run fine if it kicks in feeding a monitor that is already running.

    When you fire up a monitor and most other electronics the surge is primarily from the initial charging of the filter capacitors in the power supply (in the case of a switcher, the first set after the rectifier). Like light bulbs with filaments, there is a bit of a surge when first applying power to the c.r.t. filament. That's because tungsten has a positive temperature coefficient. Resistance is lower when cold. Many monitors have a small series resistor in the filament wiring to reduce the surge current. That reduces demand and the power supply and lessens the stress to the filament.
