I was communicating with a Finnish State TV commentator
a while back about an EU light bulb ban critical programme he was doing
It turned out pretty good (of course!) though he had little time to take up all my suggestions
It reflects what Halldor will likely say too about CO2 emissions

Professor Matti Lehtonen and his research team at the Helsinki University of Technology’s Department of Electrical Engineering wanted to find out how people adjust their home energy consumption if incandescent light bulbs are replaced by CFLs.
Matti Lehtonen estimates that about 80, maybe even 90 per cent of an incandescent lamp’s “wasted heat” can be captured for heating, if it’s in an insulated room.
Lehtonen’s team figured out how much extra heating energy is needed to replace the wasted heat from incandescent light bulbs after they have been replaced by CFLs. The team was particularly interested in how much effect the switch has on carbon dioxide emissions.
The results might seem surprising.
Lehtonen: “If you have a house with electric heating, the climate benefit is going to be very small.
More or less the same energy is then used to heat the radiators.
And if your house is heated with oil, and we calculate the climate impact of the change, with a conventional electricity generating mix [to power the lighting], we get an increase in carbon dioxide emissions.”
