I generally regard Greenpeace as a bunch of dangerous scaremogering lunatics with a proven record of falsifying the facts to get their message across (like here, here, here, here, here, here, here, here, here, here, here, here, and many more, some of which are summarised here). But this piece shows that at least they have a sense of humour - or the publicity company they hired did, at any rate. I particularly liked the bicycle idea.
(As an aside, the whole business of these low-energy bulbs makes me very annoyed. We keep getting free ones delivered, without asking, from various sources, and I am told that 'proper' lightbulbs will soon be phased out altogether. I don't like the low-energy bulbs: they give a very cold and greenish light, they take ages to warm up, and they are full of very nasty rare-earth chemicals that cause horrible pollution elsewhere on the planet. But hey, they are 'green', right, so stop complaining. It's a shame that they are seen as the solution to the problem, as the technology to produce them is dirty, and in any case they are now outdated. LEDs use far less energy, and produce better light more cleanly. I guess they will be sending us free LED bulbs and making us feel guilty again in about 2020.)
