It's simple. A pack of 4 standard bulbs costs about $1.75 (about 0.43 per bulb). ONE twist flourescent cost between $4.50 and as much as $13.00. If the twist bulb goes out before the incandescent (which they do) then the savings of energy costs during the operation of the twist bulb will likely be less than the difference in the cost of the two making the total savings actually more for the incandescent bulb. BTW, the twist bulbs actually are more dangerous because they have a high level of mercury and have been proven to be more harmful to the atmosphere. This was also found by the engineering class in their study. Look, if you are going to make such a strong statement at least do your homework so you don't look any more uninformed and out of touch than you already do.
It took a "engineering class study" to tell you that a product that contains a minute amount of toxic material is "more harmful to the atmosphere" compared to a product that does not contain Mercury.
That is just brilliant.
