Cutting the Cost of Household Bills? 370

schlumpf_louise asks: "I'm in the UK, and I'm about to move out of university accommodation and live in a house, for the first time. When we move, we will have to pay for water, electricity and gas. We'll still be students renting from a landlord, so we can't make any major physical changes to the property. The house has gas central heating and a gas cooker. Four computers will be running pretty much all the time, in addition to the usual general household appliances. What tips do any of you have for (legally) saving on bills? Are there any technologies that are worth buying for long term savings? What should we not do, or not use?" What other saving tips, and frugal suggestions might you have for a house full of college students?

    Lightbulbs that use Fluorescent tube technology, but screw right into the sockets of regular bulbs.
    - They use ~25% of the power of regular bulbs (for the equivalent light output)
    - They tend to last 5 times longer
    - The electronic balasts of modern CFB don't cause flicker (and thus avoid headaches...)
    - Modern CFBs use better phosphorescents that match the color temperature of typical incandescents.

    The only real downside is that they *are* more expensive than regular bulbs, but the energy (money) you save in the first few months allows it to quickly pay for itself.

    and every day when you leave. better yet, get an electonic thermostat if you can, and program it. turn out lights when you are not in the room. don't run water needlessly. if you aren't actually using your computer at night (uploading, compiling, serving, whatever), let the computer go to sleep or turn it off.

    In the winter months, they sell a clear plastic sheet you can tape along the rim of the inside windowsill. It is amazingly effective at preventing heat loss. Use that.

    What you should all do is work out when your computers actually need to be running.

    Leaking appliances is certainly something to consider. Unfortunately you're stuck with countless bad decisions by your landlord, including inefficient appliances, lousy insulation, poor choices in heating/cooling systems, etc. For those that aren't subjected to a landlord's provisions and can call their own shots, I'd suggest a few options we've learned:

    • Check with your electric utility for peak-demand control options: Ours has a wireless (440 MHz type frequency) way to shut off our water heater and other electrical appliances briefly during peak demand when it is experienced, saving them lots of money. By using this plan, we get a $0.06/kw hour rate vs $0.09.
    • Insulate like heck. Wish I would have learned this trick earlier on. Yes, there's a cost/benefit ratio, but I've yet to meet a rational insulating project that didn't pay back within 1-2 years (or earlier).
    • Vent heat: Got an attic? How well do you get rid of heat? Our last house actually had all the heat bottled up in the attic because the previous owner/bozo thought sealing all the vents was a good thing. Active fans based on attic temp are good things in extreme cases and are cheap to buy and install.
    • Blue-flame heaters. Live in a home older than 30-40 yrs? You probably have enough air exchange to use a blue flame heater, which is 100% efficient. Screw the old furnace or even the new 93% unit, blue flame is 100% efficient and uses no electricity! We got one after a week-long ice storm and discovered it lowered our total natural gas bill by 40%.
    • Get rid of incandescents! They generate waste heat like hell and are expensive to run. Go flourescent as much as you can. We switched out our outdoor lights too (including former mercury bulb yard lights) with this and have seen a noticable drop in electric rates.
    • Design for low cost: Things that must be left on must be cheap: That's my rule. Rather than keep all my systems running, I have a low draw laptop that's hooked up to a flat-screen (tested to make sure it doesn't suck power when off). I like to leave a few lights on when we're not here - they're all converted to flourescent. Anything that has to be left on must be cheap.

    If you have a nice gas cooktop and some cooking skills you can make a lot at home. Uni cafeteria can be a huge money drain if you're eating 3 meals a day. For 4 people, you could probably save 50 pounds a month if everyone chips in and does some food work. Nothing fancy, but stay away from prepackaged food also, it's just as expensive and not healthy either.

    Landlords generally want the property to look good and clean to attract tenants, they don't spend a lot of time or energy sealing up a house.
    A few tubes of caulk to seal up small cracks and some stick-on weather stripping for windows and doors will go a long way toward keeping the temperature more stable. Also there are foam gaskets you can put behind the wall plates of switches and sockets to keep drafts out.

    Drapes open on cold days to get in the sun's heat. Closed on warm days to keep it out.

    Showers are a huge point of waste. A few dollars/pounds will get you a shower valve you screw in-line with the shower head. You can then reduce the water flow when you're not actually needing it and then turn it up again to rinse off. Showers generally cost you 3x, incoming water, heating water, waste water charge.

    If you have access to your water heater and the pipes coming from it, add insulation to them. A water heater wrap and some foam tube insulation will keep the water hotter for longer in the tank and the pipes to the shower.

    If you have a smaller shower room, hang your wrinkled clothes in there, it will help remove wrinkles and prevent you turning on the iron (ha ha, I know).

    Keep the fridge full. The more "stuff" in the fridge the more efficient it is. Air heats/cools quickly and escapes readily when the door is opened. Stuff in the fridge will help the temperature come back to cold quickly and reduce run-time. Also, keep the door closed as much as possible. Standing in front of the fridge with the door open searching for something to eat is a tremendous waste.

    Line-dry your clothes indoors instead of machine drying. On a breezy summer day indoors with open windows the evaporation will cool the air; in the winter the humidity will help make the air feel warmer at lower temperatures.

    When cooking, use lower gas settings on the cooker. High-heat spills a lot of heat past the pan in to the air. Medium-low heat will usually get the job done just as well with only a slight increase in pre-heat and cooking time.

    Find, and keep clean the filer for the central heat if it's forced air.

    Try to cook for the entire house at one time instead of each member cooking their own meals. Economies of scale and all; better to heat the kitchen up once for 20 minutes that 4-5 times 10 minutes each.

    Low-cost 1/2 Styrofoam panels can easily be cut to fit in to windows to block out cold nights, or to fit around the outside of a particularly lame fridge.

    This is the kind of thing that can test friendships.

    Several of these have been mentioned before:

    • Keep the heat down and wear sweaters. Turn down the heat when the house is vacant and when everyone is sleeping (buy blankets rather than gas)
    • Practice zone heating: don't heat rooms that aren't being used
    • Check for drafts around doors, windows, electrical outlets, etc. The landlord would probably approve weatherstripping repairs, or use rags or plastic as nonpermanent seals
    • Unplug tvs, entertainment centers and other devices that have "instant on" or "warmstart" circuitry when not in use
    • Get together and plan your kitchen stove use. When an oven or burner is brought to heat, you want everyone to do their cooking before it is shut off again.
    • Assuming you've got a washer and dryer, pool your laundry
    • Don't use the dishwasher
    • Plan your shower usage. Devise a contract for how many minutes of showering or bathing you will each do every week.
    • Turn off the computers when not in use. If you can't do that, use powersaver modes and at least turn off any peripherals.

    Controlling hot water use is often the hardest part.

    1. Think about replacing your entertainment appliances with a communal computer. A relatively low power PC hooked up to a decent LCD can play just about any sort of media type you can think of. It is also quite a bit more efficient than a bunch of individual devices in "sleep" mode sucking down 10Wh+. Turn off the sound system for such a computer when it isn't in use and place the system itself in sleep mode or hibernate or what have you when not in use.
    2. Convince your house mates that switching to LCDs in going to save everyone even though they're relatively expensive up front. A 19" CRT sucking down 100W will cost a fortune compared to the operational cost of a good LCD. The less power used means the less heat generated which leads to lower home cooling costs in hotter months.
    3. Turn the thermostat up in the summer and down in the winter. In the summer wear shorts and short sleeve shirts, sweaters and thicker pants in the winter. Grab some cheap solar shades to go on the outsides of south facing windows, they keep a good 70% of solar radiation from entering the window and require next to maintenance. Do what you can to seal up the windows in the winter time to keep cold air out and warm air in. There's lots of thermal seals for windows available that don't require permenant changes to the structure of the windows thus being renter friendly.
    4. Get a Watt meter. It's a little device you plug in between an appliance and the wall that can tell you the device's electrical load. Plug everything into one of these to figure out what is sucking down the most power when on and/or off. Grab some power strips or switch adapters for outlets to keep these power sinks from hiking up your electrical bill. You'd be surprised about how much power is used by appliances that look "off". Kitchens and living rooms are huge power sinks.
    5. Replace incandescent bulbs with CF ones. CF bulbs costs a bit more than incandescents but last quite a bit longer and use a fraction of the power to produce the same amount of light. You don't save up front with CFBs, you save months down the road when the power savings and long life have paid for the bulb several times over. CFBs are also getting cheaper so price is even less of an issue than it was just a few years ago. Make sure people in the house get into the habit of turning off lights in unoccupied rooms.
    6. Look into replacing a digital alarm clock with your cell phone. My cell wakes me up in the morning and has a clock that is always set. It works properly after an overnight power outtage.
    7. Cook for everyone at once and pick up some heat trapping storage bags (the sort used for camping and picnics) to keep food warm for latecomers. Try not to cook too much or else you're going to need to store that extra food for later...
    8. Get a small refrigerator and shop for only one or two days worth of meals. A smaller fridge is going to save on your electrical bill. Shopping on a smaller scale is a little less convenient than bulk shopping but can be done by a single person on the way home from work/school more easily than bulk shopping. It also means you tend to have fresher food and don't buy things you forget about that then go bad wasting the money.
    9. Agree on a beer everyone enjoys and buy kegs or mini kegs rather than cases with bottles. Kegs are cheaper than cases and can be reused.
    10. Recycle. I don't know about the UK but overhere in the Estats Unidos you can get a few bucks from every few pounds of aluminum and glass you recycle. This is nice after BYOB parties as you get a bunch of free change just by cleaning up and heading to a recycling center.
    11. Carpool and/or ride a bike. If you're not too far from work or school ride a bike. You save on gas and have better parking options. A good bike will make for a comfortable ride and you'll stay in shape even drinking a college portion of beer.

    Drop a few bills on an LCD monitor. New LCD's draw far less power than CRT monitors. This is especially true if you're using an old 14" clunker that doesn't do any sort of real power saving. Combine this with a VGA switch (or a KVM switch) to cut down on what you'll need to have plugged in.

    Find and eliminate "wall warts", those little black inverters / chargers that are constantly drawing anywhere from 4 to 15 watts. I'd suggest getting a cheap power strip (one that has a switch) and putting it on top of your desk, then taking plugging as many of the warts into that as possible. Phone charger, laptop brick, iPod Charger, PC speaker inverter, and anything you can plug in that has a remote control.

    When you're not using those items, turn off the strip. You can cut out anywhere from 20 to 80 watts of useless power. Multiply that by the hours you save (because hey, your PC speakers need to be sucking power when you're fast asleep...) and you can make a decent dent in your bill. (it's also a bit healthier for battery charged items to not be sucking power all the time.)

    Aside from that? Compact flourescent bulbs help, and not being a dumbass helps more. Don't heat anything with electricity if you can avoid it, don't leave lights on all the time, enable powersave features on the PC's when you can.

    Actually, the small "dorm" refrigerators are so horribly built that they use about as much electricity as a normal sized fridge. The thing that will make a difference, though, is having a new fridge versus an older one. Same goes for old A/C units, don't bother with those.

    This is a common misconception. Modern consumer hard drives are designed for lots of starting and stopping. Where you will actually wear them out is leaving them spun up all the time. You'll normally wear a drive out in (a very rough as it depends on manufacturer) two thirds the time using it in a permenatly spun up server type pattern as apposed to the standard start/stop desktop pattern.

    There is a reason server rated hard drives cost more and it's not just because they spin faster.

    1. Compact flourescents. Been mentioned all over here, but can't be stressed enough. Modern bulbs work on standard sockets, produce a fairly decent color of light, and no flicker. Also, most large stores carry "value packs," which run $2 US or less (imagine prices can't be that much different there). I know where I live the local utility will rebate you for a certain number of these as well. I saw about 75kWh reduction in my bill over the course of a month by replacing every light I could with these. Note: you generally only want to replace lights that you run for at least an hour at a time with these. These will pay for themselves in six months or less.

    2. Programmable thermostats. Run $35 US or less here. Again, many utilities will rebate you, but YMMV. This is also the kind of improvement that landlords generally won't complain about, and it will more than likely pay for itself over a winter.

    3. Shorten your showers.

    Finally, about those computers. I do not know why you need four running 24/7, but you should reconsider this. Assuming they are desktops, you are drawing a LOT of power this way. I would recommend if you are using any of them for general uploading/downloading of "stuff" you should consider picking up a laptop with a broken screen and run it either headless or through a KVM switch. Attach a large hard drive, your printer, etc. and network it. Then keep all the other computers on standby (or hibernate...I'm assuming you want them to come on as fast as possible, though). The power you save over a year will probably pay for the laptop, hard drive, and any networking accessories you end up needing to buy. Look around, and you can probably find a laptop with more than enough power for fileserving, print serving, and P2P for dirt cheap...and it will draw a fraction of what even one of those desktops draws.

    by Anonymous Coward on Tuesday February 07, 2006 @05:38AM (#14658452)
    I've seen several good suggestions in the comments, but many of the commentors do not seem to be taking note of the situation, or are not familiar with the state of most houses rented to students in the UK (e.g. A/C doesnt exist).

    Two principles (1) get rid of the things you don't need (2) reduce the things you need/have no choice about.

    I'll mention energy-saving devices at the end.

    Things you don't need

    - any form of internet access, whether dialup, dsl or cable - if you're still a student, use the university-provided facilities. Annoying, but cheap.
    - and form of subscription tv, cable, sky, etc. Stick to the terestrial channels.
    - you probably don't need a landline phone if *everyone* in the house has a mobile.

    Things you can reduce

    Heating
    - turn the thermostat down to 17C and wear extra clothes. Multiple thin layers are better than fewer thick layers - e.g. tshirt+thin sweater+baggy sweater.
    - make sure every window has curtains. Hang a blanket if they don't. Contrary to what someone else suggested, opening curtains in winter to let the sun in will NOT warm the average UK house unless the window is double-glazed and catches direct sunlight (south-east or south-facing) for several hours. And you still need to close the curtains once the sun moves past. In general keeping the curtains closed will keep more heat in than you gain through sunlight. Exactly when to open the curtains during the day (to save on lighting costs) is a judgement call.
    - turn off the hall radiator and keep room doors closed. You don't live in the hall. Heat the rooms you use and keep the heat in.
    - wear pajamas in bed (!) fleecy ones if necessary.

    Cooking
    - avoid the oven, whether gas or electric.
    - put lids on pans when you cook and turn the heat down once they are at the boil. Even for rice and pasta. Incidentally heating water is energy-expensive, but generally the kettle is more efficient than saucepans, and a gas boiler is more efficient than the kettle. Use hot water from the tap, boil in the kettle, pour into saucepans at the moment you need to use it.
    - if you're house-sharing, share meals too. Separate meals waste fuel.

    Washing/Cleaning
    - dont use a tumble drier if you can reasonably avoid it. Use a clothes line, get a free-standing airer and/or drying racks for radiators.

    Lighting
    - turns lights OFF! (turn anything off when not used. And that's OFF, not standby).

    Energy saving devices.

    Generally, on a limited budget (student), there are few energy saving (E-S) devices worth buying because they're initially expensive and they wont have paid for themselves until long after you're a student. E-S light bulbs take around 5 years. On the other hand if you take the long view, they're only expensive compared to plain bulbs (£5 or less) and you can take them with you after.

    There are a lot of folk on here who don't know a thing about the UK or what a typical student rented house would be like. Advice about A/C is irrelavent.

    Anyway. Assuming no structural changes allowed (so you can't touch wall cavities etc) and assuming you don't have UPVC double glazing etc.

    1. Draught insulation on all doors and windows. Find every draught and stop it. You can get thses strips in Homebase, Do It All etc. They come in different thicknesses so choose wisely. Be prepared to get dirty cleaning all the spaces in the joints where the spiders live otherwise the strips won't stick.
    2. When it's cold, wear more clothes and only heat the rooms you use and keep the doors shut so you don't heat the rooms you're not using.
    3. If you want to heat a room quickly (say you're the first one back after being at lectures all day) get a small desk fan and set it blowing across the radiator in the living room. It will cirulate the warm air surprisingly quickly.
    4. Cook and eat meals together as a group. This is cheaper, you'll eat better and it's relaxing to have everyone sit down together after they have all been out (hopefully) studying all day . Do the obvious like learn how to skin and quarter a fresh chicken rather than buy expensive chicken pieces (hint: kitchen scissors). You don't need to be a great cook, learn to do one simple meal such as a Chilli Con Carne, expand your repotoir later. We had a complicated looking list (it would be a spreadsheet today) of money spent by each person either for the group or for other individuals so we could work out who owed each other what at the end of the term. It saved any arguments and meant the whole 'cooking for the group' thing did work.
    5. Much has been said about computers already. If you can get to a power socket in the library, consider working there. This would obviously require a laptop but you keep warm, have free electricity and hopefully *don't* have a distracting net connection.
    6. If you have big windows, consider that platic double glazing stuff you can get. For what ammounts to some double sided tape and a sheet of clear plastic stuck over the window, then shrunk tight with a hair dryer you do get pretty good insulation.

    One more thing. University is getting stupidly expensive now in the UK, you are going to get into a lot of debt anyway. But you are not there to get a degree as cheaply as possible. You are there to enjoy yourself, to learn about life and yes; to get a degree. So have some fun along the way and don't sit freezing in a room when being warm isn't going to make much difference to the £20k debt you might well be facing at the end. Which is why I don't suggest not drinking beer. You'll be spending more on beer than on food and possibly utility bills as well.

    If you don't watch a lot of TV, and the local cable company is unwilling to sell Internet access to those who aren't cable TV customers, then you can't get cable Internet access.

    if this happens you better ask for the rep's boss on the other end of the line because they will sell you just road runner and no tv. Many cable companies try to bully people into signing up for cable tv along with their roadrunner, but you don't have to have both. If it was actual policy to have buy both time warner would be in the same boat as microsoft with their bundling issues. However, they simply try to make people think that they need to buy tv to get internet, but when you ask around and talk to enough supervisors at your local cable company you will find that this is a lie.

    Most modern water heaters are well-insulated by construction, and do not need the insulation wrap. The best way to determine if you need the wrap is to put your hand on the side of the water heater. If it feels warm, then the heater is not well insulated. Use the wrap; or better yet, replace it with a modern one, which will probably work better and be better insulated.

    Even when you can't make physical changes to the house (if you're renting, no ripping up walls to add insulation), there are a number of ways you can insulate better. Home Depot (or your country's equivalent) sells plastic sheeting that you can put over windows, which eliminates drafts and adds a lot to the insulation of the windows, which are often the worst offender for heat leakage.

    Moving bookshelves to outside walls can help as well; you might be surprised at the insulation factor of six inches of paper.

    Checking outside doors for drafts and eliminating them helps too.

    >The only reason most LEDs use so little power is that they emit so little light.

    Your facts are WAYY wrong. If you want to refute something, at least do a lazy Google search and you could have saved yourself a bad post.

    1) LEDs approach 100% efficiency.
    2) Florescent lights are about 50% efficient (and varies.. compact Edison style bulbs are less efficient... LED doesn't care about the form factor)
    3) Incandescent lights (including halogen) are about 5-10% efficient. That is NOT a typo they are 90% heat waste.

    Not sure where the heck you live, but in most US cities they have begin using TWENTY WATT LED lights to replace TWO HUNDRED WATT traffic bulbs. The LED lamp uses 90% less power but has 100% the same brightness.

    The LED bulbs longer and does not burn out all at once -- lowers the accident rate and requires less maintenance.

    > Not only that, but white LEDs cost so damned much that even if they were more efficient it would be a REALLY LONG TIME before you ever saw return on your investment.

    I'll concede that point.

    It also takes a REALLY LONG TIME to recover the investment in a hybrid.

    It's gonna get cheaper now that China is in the manufacturing game. Their government has "selfishly" decided they don't want to export their newfound wealth to Saudi Arabia they want to keep those energy costs at home (something a lot of Americans would shrug off unfortunately).

    I'd expect something competitive with CF bulbs in 4 years tops.

    Good thing I did not ask you before I bought one. And yes, I only bought one they ARE expensive.. like $35 when I got one and down to like $25 now. The nice thing about it is there's no heat waste. When the cost goes down, I expect air conditioning to be cheaper since you're not fighting waste heat generation.

    The early adopter applications will drive this down... think of all the bulbs running in car lights and RV's and motorcycles. LED replacements for those are just as bright and not much more. Bright LED brakelights are already standard on many commercial trucks.

    I got them where the AC did [slashdot.org], at Home Depot in the $9.99 6-pack package. This offer might not be available on-line, but they're right there at the checkout lanes.
    The CF bulb is 32 times the cost of the incandescent.
    Even at that price, the incandescent burns enough energy to make up the difference in < 2000 hours. I've paid $20 for some 3-way circle-tube CF's. I've gotten my money's worth out of them.

    Several dimmer switched on the site are under $10. A dimmer switch will dim several lights at once.
    Light output of an incandescent is proportional to the 3.1 to 3.4 power of applied voltage [misty.com]. If you run the dimmer down to where the bulb is only taking 25% power (about what the CF consumes relative to the incandescent), you won't have any useful light output; the
    For the cost of 4 bulbs and a switch I can have nearly, if not more, energy savings and better lighting as a single CF bulb.
    You'll be getting many fewer lumens/watt and consuming way more watts overall, and it gets worse and worse the further you dim them [lighting-f...g-fans.com].
