I haven't read the whole thread, but surely somebody has already written....
Will the last person to leave the UK please switch off the environmentally friendly wind turbines, wave power generators, solar panels, heat exchangers and those dull bulbs; don't forget to collect your personalised hair shirt by the exit.
I love the planet, but my geriatric eyes need help, these new bulbs are not the answer; yes they illuminate, but to a lesser degree than the lights they are replacing, consequently people use more lights. Watch any news interviews from a government department. No power or light shortages there, lights and air-conditioning/heating everywhere. .
Best I stock up on AAA batteries for my reader's light.
