This is a most excellent place for technology news and articles.
Once you're doing resistive heating any resistive element is just as efficient as any other. Incandescent light bulbs have three advantages: They are cheap, easy to work with, and it's really obvious when one is turned on.
As for your link, it's talking about arguments about which books should be made available at school and local libraries. In no sense is that even related to the federal government banning books.
Well I've never said the US federal government is banning books, but I wish people were as mad when their local schools and libraries do that :-)
