How does this compare with the mercury emitted producing the extra

Quite badly if compared with sensible generation methods such as
nuclear.

To advocate nuclear, which generates highly toxic waste which needs to
be kept out of the biosphere for orders of magnitude longer than the
pyramids have been around, while criticising the Hg in CFLs, is definitely
one for the Mote & Beam department.

The question concerned the amount of mercury emitted in generating
the electricity. However, like it or not unless there is some
serious depopulation there is not a cat in hells chance of windmills,
CFL's and the like making a significant difference to the worlds
emissions of CO2 in the next 100 years. The only current technology
which might is nuclear and the one which should be attracting money
is fusion not greenwash.
