You can't make people reduce their electricity usage: "Up to 3 low
energy lamp fittings had been specified in the original proposals for
the dwellings in the sample. The fittings had generally been installed
in hallways, landings and some bedrooms, but few remained in the
completed and occupied dwellings. Most had been removed by the
occupants, and occupants expressed their intention to replace soon
those few that remained." BRE Survey 2004

I found an EU survey on adoption a year or so back, which
broadly agreed. Number one reason given for not using them
was not fitting in lampshades/lightfittings people want to
use or already have.

That will only make a difference if the selling price reflects the
cost of production rather than being based on an assessment of what
the market will bear,

Not helped by the EU slapping import duty on them, so price has
stayed artificially high in the EU for some time (not sure if
this is still the case, as I've seen cheaper ones recently).
