With the passing of the Energy Independence and Security Act of 2007, many thought that incandescent light bulbs were going to disappear, because they could not meet the new efficiency standards. While it is true that many styles of lamps have already gone away, this article I came across appears to give the incandescent lamp some hope for the future.http://www.nytimes.com/2009/07/06/business/energy-environment/06bulbs.html
See, manufacturers can often make more efficient products if they set their minds to it. Unfortunately economics says they continue to produce what they always have, and what they have an investment in. That is, until something happens to make their old standby products obsolete.
Make no mistake. If you are a manufacturer, and you have a huge investment in factories to produce a product, changing those factories to manufacture a new product can be expensive, time consuming, and a bit daunting. We cannot blame a business for wanting to stay viable, and make a profit on their investments. This is one area where reasonable, and responsible, legislation is not only proper, but can force change in a positive direction.

This is a link to the ENTIRE Energy Independence and Security Act of 2007. Good luck trying to read it:
Since the act is, as usual, highly indecipherable, a summary of it's provisions is handy.
