Is it better for the environment to switch from incandescent lightbulbs to compact fluorescents? The answer is... not necessarily.

Compact fluorescents are four times more energy-efficient and can last up to ten times longer, but they also contain mercury. The mercury can be released during manufacturig and disposal.

According to a Yale study, the effectiveness of the switch varies by region depending on how heavily each area depends on coal, on the chemical makeup of the coal by region (some coal has mercury), and whether or not recycling programs exist for CFLs. In general, the cleaner the energy environment already in place the more detrimental the switch to CFLs. Who knew?

The US states with the most to gain by switching are North Dakota, New Mexico and West Virginia. The countries that topped the list are China, Romania, Bulgaria and Greece.
