They say that energy saving bulbs (like the ones you can buy everywhere now - with small flourescent tubes) consume less than 20% of the power of normal bulbs. This is great from an environmental point of view - apparently. But doesnt anyone ever stop to think about the energy processes gone into making them? The chemicals used and the resources needed to manufacture them? Surely making a PCB, assembling the components, manufacturing the tubes, coating them with phosphor etc. etc. is far more damaging to the environment than using a spherical blown bulb with a bit of tungsten in it? I'd like to do some research into this to find out exactly how much energy these so called energy saving bulbs actually save???
