Spectral House

So usually I am a big fan of ultra modern houses, but this one might be a bit much, today we have a 215 square foot house out of Paris France.  The renovation was done for about $50k and instead of paint, they decided to bring in color with different light bulbs.  The sodium light-bulbs bring in a really interesting architectural quality, with it being such a raw mechanical element contrasted against the stark white.  The designer noted:

The apartment is designed in a simple and neutral expression, without color or particular detail, annihilating any architectural expressiveness or narrative to leave only the logic of composition generated by light.

EU No Longer Selling 100w Light Bulbs

Apparently today the EU is banning the production of 100w light bulbs.  While I rather like this idea, it has been met with much opposition for various reasons.  However, there was quote by EU commission which was rather startling about how effective this change will be.    lightbulb-idea

The EU Commission projects the ban on the energy-inefficient bulbs will save about 40 terawatt hours of energy in the EU per year — enough to meet the energy demands of a small country.

Ya folks that is Terawatts.  Just to kind of wrap your head around that, the typical home today uses about 26 kilowatts a day.  There are a thousand watts in a kilowatt, a thousand kilowatts in a megawatt, and a thousand megawatts in a gigawatt and a 1000 gigawatts in a terawatt, in the end a terawatt is 1,000,000,000,000 watts!  (thanks for the correction Grant :)  ) Times that by forty and it is seriously astounding!  Treehugger wrote this article about how people are hoarding these bulbs and its their point counter point against these bulbs.

1) Compact Fluorescents have Mercury in them, and that’s bad for the environment

Mercury is bad stuff when it gets into the environment, but the main source of environmental mercury is from coal burning power plants. As Pablo showed in Should I Worry About Deadly Mercury In My CFLs?,

Over 5 years (the life of a CFL) it may be responsible for 2.4mg of smokestack mercury emissions, so a total of 6.4mg of mercury over the life of the bulb. By comparison the incandescent bulb is responsible for almost 10mg of mercury emissions over 5 years. But CFLs can be recycled to recapture the mercury. Smokestack emissions can not be recaptured after they enter the atmosphere.

2) If you break a bulb you will need to call a Hazmat Team to clean it up.

The two to five milligrams of mercury (smaller than the nib on a ballpoint pen) will evaporate quickly; open the windows and ventilate the room. See Ask TreeHugger: Is Mercury from a Broken CFL Dangerous?

3) Incandescents put out useful heat in some parts of the country.

Electricity is a very expensive way to heat, and the bulbs are not putting out the heat where you need it. Even if this were not the case, it is only true for half the year. More: Study Shows Incandescent Bulbs Are Warm and Toasty

4) I don’t like the quality of the light.

The Energy Saving Trust in the UK set up a sort of Pepsi challenge to see if people really could tell them apart. Smart Planet reports “Although 70 per cent of the 761 shoppers that were asked to step inside the booths thought they could spot the difference, 53 per cent got it wrong or admitted they couldn’t see any difference. A whopping 64 per cent of the guinea pigs said they preferred the light in booth A, which was in fact the energy-saving lightbulb.Last Post Ever on Compact Fluorescents, It’s Settled


5) I am waiting for LEDs.

So am I. But right now most have lousy colour balance, are not bright enough and are still very expensive. They have a long way to go before they will be competitive. Meanwhile, if you wait five years for them, you will have paid a lot for electricity, contributed a lot of CO2 and added 3.6 milligrams of mercury to the environment.

6. They give me headaches.

Um, join the line and stock up on incandescents, and hope that LEDs are available before you run out. Or, try different brands; some people react differently to different types.
