Personally I think it's all a lot of nonsense. We have to change our light bulbs when countries like America and China are chucking out vast quantities of carbon emissions? Once again it's the Government trying to take our minds of f what's really important. I'm not saying there's no such thing as global warming, I'm just saying that changing the light bulbs in our tiny island is not going to make a noticable difference! It'll make a difference to us, the consumer, though cost wise ... surprise, surprise! New lamps, new fittings, new switches, an expensive pastime I see coming!
