According to this:

The energy efficiency of compact flourescent is 40-70 lumens per watt compared to incandescent
efficiency of 10-17, roughly 4x more efficient.
What is ignored many times is the manufacturing/distribution/other costs. Read: costs=resources.
If a flourescent bulb costs 5x more, it takes 5x more resources to make (given no government intervention). You *may* save a bit of resource here, but you give up more over there.
Its just like recycled materials. In general, they cost more than virgin (I know, I run the numbers nearly every day here at work). The reason for that is that collection/sorting/transportation/cleaning/reprocessing takes more resources than to make virgin from scratch. In many cases, the use of recycled product only looks good as far ahead as the end of one's nose. **this could be fixed with infrastructure, but as of now, the cart is waaaaaay before the horse. Actually, I much prefer "waste to energy" local facilities over recycling, but I digress.....
It does, however, make many people feel better about themselves...
A family friend used to be a big wig at a glass company. By law they had to buy old glass from people but the cost to reprocess it was so high they just took the glass they were forced to buy to the dump. Certain glass they would keep, the blue glass with cobalt added I think it was.
