CF light bulbs provide a tremendous energy and emissions savings. They are slightly more expensive up-front but last many times longer and typically pay themselves off within several months, leading to large savings over several years.
The costs and benefits here are a range around the assumed household averages of at least 23 light sockets. A range of 2-6 hours of use each per day is assumed.
The only potential drawback of CF bulbs is the presence of a small amount of mercury, which means they should be disposed of properly. New CF bulbs are coming available that contain less than half the mercury of current models. This concern needs to also be balanced with the reduction in all forms of polution from carbon-based electricity generation with the lower energy requirements.

If everyone did this ...
If every household in the US did this, it could save a collective 211,200,000 tons of CO2 per year!
This would be equivalent to:
- Taking 41,411,765 cars off the road for a year
