Dimwits: Why ‘green’ lightbulbs aren’t the answer to global warming

…In addition to this, lowenergy bulbs are much more complex to make than standard bulbs, requiring up to ten times as much energy to manufacture. Unlike standard bulbs, they use toxic materials, including mercury vapour, which the EU itself last year banned from landfill sites – which means that recycling the bulbs will itself create an enormously expensive problem.

Perhaps most significantly of all, however, to run CFLs economically they must be kept on more or less continuously. The more they are turned on and off, the shorter becomes their life, creating a fundamental paradox, as is explained by an Australian electrical expert Rod Elliott (whose Elliott Sound Products website provides as good a technical analysis of the disadvantages of CFLs as any on the internet).


If people continue switching their lights on and off when needed, as Mr Elliott puts it, they will find that their ‘green’ bulbs have a much shorter life than promised, thus triggering a consumer backlash from those who think they have been fooled.

But if they keep their lights on all the time to maximise their life, CFLs can end up using almost as much electricity from power stations (creating CO2 emissions) as incandescent bulbs – thus cancelling out their one supposed advantage.
