They have mandated efficiency standards that can only be met by switch mode
power supplies, effectively outlawing the old linear power supplies. If you
do a search of the forum, you'll find where Andrew Ward asked whether he
should replace the linear wallwart for his alarm system and I gave some
comparisons of the efficiency of a linear PS wallwart vs a SMPS wallwart.

BTW, it would require a very large linear wallwart to waste 5-10 watts -
most waste a very small fraction of that.
