Well the Official Government Line is that we have to lead by example, as in how can the West pontificate about the need for the Far East to desist from belching carbon into the atmosphere if we aren't trying to do so ourselves. Like it'll make any difference. David I'd like to see the figures - what savings from switching from incandescent lamps to CFLs are projected to be, together with the assumptions behind the figures. For comparison, I think the Chinese are building about two coal powered power stations per week (URL:http://news.bbc.co.uk/1/hi/world/asia-pacific/6769743.stm). I suspect there are better ways of achieving more savings than replacing incandescent lamps. For example, I would have thought that improving the efficiency of electric hobs and heaters would save more energy overall. There's an awful lot of resistance coil electric hobs out there, and mandating the use of induction cookers would help on the energy efficiency front. There's also a rather large number of storage heaters - replacing them with air-source heat pumps (aka air conditioners) would be more efficient (but have the effect from moving the load from the night-time to the day, which might not be what is wanted). Banning architectural lighting would help, as someone has pointed out, somewhat acerbically. It's worth pointing out that switching electricity generation from fossil fuel based to non-fossil fuel will reduce carbon emissions - so powering incandescent lamps from renewables or nuclear is carbon neutral. Perhaps one could require those who wish to use incandescent lamps to use a 'green' electricity supplier. Norway generates more power per year by hydro than it uses, so CFLs are not especially popular there. As someone else pointed out, if you really want to reduce consumption, reducing the population is a good bet. Don't have kids. A rerun of WW1 would help, and an economic depression will reduce demand as well. A rerun of the Black Death or the 1918 flu epidemic would also work wonders. Avian flu anyone? The D-I-Y approach would be to commit suicide - catchy tagline there - "Save the planet - kill yourself.", but would be difficult to market. Asking committed environmentalists to lead by example and drop dead might be taken the wrong way. Sid |

It would of course have had no effect whatsoever on the final outcome nor would it have delayed it by any measurable amount. Changing light bulbs has the same order of magnitude of impact as issuing teaspoons on the Titanic would have. If the population of the UK was entirely eliminated next Wednesday it would have no measurable effect on the progress or otherwise of climate change. You don't solve a problem by ignoring its causes and instead playing around with stealth taxes in the margins with pious mutterings of "every bit helps" or "everyone must do their bit" to rally the ignorati. If "something has to be done" then that something must involve massive population reduction worldwide and I don't see any of the greenygroups being brave enough to campaign for that. There is nothing more hypocritical than green evangelists with children. You reactionary old fart! Hooray! There is only one "solution" to the effect we are having on the ecosystem. As you say, that is for 50% of the world's population to die (at random). The developed countries' demand for fossil fuel will collapse and food shortages in the underdeveloped areas will cease. Anything less is tinkering really. How anyone can imagine that banning our incandescent lights is going to have any effect alongside the industrialisation of China and India is bonkers! And to add to that, what about the deforestation of this world? Isn't it that trees remove carbon dioxide from the the atmosphere and turn it into oxygen. That was what I was taught in school. Dave |

Reminds me of a storey someone posted here many years ago. Moved into a new house, only to find the previous owners had packed up and taken all the light bulbs with them, so a quick trip to the shops was required. A couple of weeks later, peered up into the loft, and was surprised to see there was a lightbulb left behind -- they'd missed one. So he carefully removed it, packed it up, and posted it on the the previous owners... -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

It is possible to make dimmable fluorescent lamps by separating the control gear from the tubes. One can see this with larger fittings, but this has been difficult to reproduce with a small lamp that has the control gear and tube integrated in one unit. We had dimmable fluorescents in the lecture theatres at university, back in the early 80s. It's not like it is a new technology, but you are right about it being more difficult to handle over just two wires, when the control gear is in the lamp fitting. I think the ultimate solution would be sending signal and power separately to the bulbs, i.e. full power piggy-backed with a signal to tell the bulb what brightness to set itself to. It would work kind of like those X11 home automation systems, with the receivers built into the bulbs. -- JJ |

We had dimmable fluorescents in the lecture theatres at university, back in the early 80s. It's not like it is a new technology, In the '80s (potentially installed in the '70s) it would have been done using a large saturable reactor, or maybe a large variac. I've never seen one but potentially the size and weight of a volkswagon beetle. but you are right about it being more difficult to handle over just two wires, That can be done easily enough using semiconductor ballasts by varying the AC power input. Our equipment can be dimmed down to about 15% that way. Eventually there is not enough energy going into the tubes to keep the filaments up to temperature, and the tube may not start very well if it's switched on at a low power setting. Lower outputs can be achieved by feeding the ballasts with a seperate feed of full mains power and driving the filaments from this via a filament transformer. when the control gear is in the lamp fitting. I think the ultimate solution would be sending signal and power separately to the bulbs, i.e. full power piggy-backed with a signal to tell the bulb what brightness to set itself to. Eg Osram/Sylvania quicktronic : http://www.sylvania.com/ConsumerProducts/LightingForHome/Products/BulbType/Fluorescent/Quicktronic/ It's a simple 0-10v analogue control system which makes it possible to achieve automatic balancing of light output in display signs as tubes age. It would work kind of like those X11 home automation systems, with the receivers built into the bulbs. I've not seen any addressable ones - yet. DG |

Commuting to and from work in the winter - as of about now requires lights in both directions but only some of which is on unlit roads. I just wish motor manufacturers would stop putting these silly bulbs in their headlights and "fog lights". It seems that we are now conditioned to use lights to announce our presence which increase the difficulty for others to see pedestrians. |

If I reduce the power consumed by light bulbs in my lounge, the central heating switches on, heating my whole house, using more energy. In the UK we heat our houses for a large part of the year, especially when it's dark, why not allow the light bulbs to do it? That is simple enough logic isn't it. Why not drop an email to Hilary Benn about it. Don't exceed two syllables in any word. The person who reads it to him should be able to explain it in a way that most people should be able to understand. It's doubtful that he will though. I trained as an engineer, and for me what I find most disheartening about this country is that a useless tosser of a bloke like that is making technical decisions. I don't know whether or not it's a fundamental tenet of democracy that people who are completely unqualified make the decisions or it's just the way we do it. I don't even imagine the way he got the job had anything to do with democracy, who voted to give him it? DG |

If you only need heat in your lounge then using a local heat source may be more economical, but much less so if you put it a foot below the ceiling! In the UK we heat our houses for a large part of the year, especially when it's dark, why not allow the light bulbs to do it? Firstly, for a good part of the year you're not heating your house, and this includes the times in the heating season when it's up to heat and the thermostat has switched the heating off Bzzt. Heat input from lamps will still contribute to reduced (gas ) consumption by delaying the time when the thermostat energises the boiler again. and secondly electricity is a high CO2 fuel But it could come from renewables or nuclear. then it wouldn't be. so the environmental pressure is to cut the use of electricity - why do you think that electricity is something like 3x the price of gas per delivered kWh? Inefficiency, bad organisation, too many people in the distribution chain (Stood in Sainsbury's with clipboards or walking round housing estates) taking a cut ? DG |
