Various governments around the world are banning Incandescent light bulbs in favor of "greener alternatives" such as CFLs. Specifically: Philippines, European Union, Ireland, Switzerland, United Kingdom, Canada, Cuba, Oceania, Australia, New Zealand, Argentina, Venezuela, and the USA.
In the USA, California, Connecticut, and New Jersey have individually enacted their own individual legislation, and the rest of the United States is set to catch up with a federal bill (that has been passed) that requires "minimum efficiency" by 2014.
The ban of incandescent light bulbs is utter lunacy. Not only does the government have no business making such regulation, but the whole purpose is supposedly to be "greener". Yet replacing harmless incandescents with mercury full CFLs is not greener. When the CFLs end in the trash their mercury seeps into groundwater and, as the greenies keep on telling us, causes untold damage to the environment. Mercury was used in a plethora of electronic devices until it was banned exactly because of that. And now it is making a comeback, and not just that, but the greens are banning the mercury free bulbs in favor of the bulbs with mercury.

Not to mention there are health hazards. For example, if you break one you should run out of the room and not return for 5 hours. (and air it out). and what if it springs a leak and you haven't noticed? your health is at risk, the environment is at risk, and all because some ignorant idiots want to reduce the emission of carbon dioxide. Take a deep breath, now let it out. what you breath out is carbon dioxide. A harmless substance that plants require to survive and consume in such great amounts that only 0.038% of our air is made out of it.
You know what this idiocy reminds me of? the great leap forward: http://en.wikipedia.org/wiki/Great_Leap_Forward
where communist pseudo science was enacted into law by china, and instead of a "great leap forward in economic power" somewhere between 20 and 43 million people died of starvation and the economy was utterly devastated.
