or GOOGLE incandescent light bulbs canada for a long list of info
The honerable minister quotes an Austrailian study, while forgetting that the climate in Canada is not very Austrailian like.
Incandecent lamps optimistically produce 20% visible light, 80% heat. So, in a cold climate, during winter-time, they should be considered 100% efficient. During the summer, we get daylight.... lots and lots of daylight, so summertime lighting is a non-issue. In BC, electricity is about 70% the cost of fossel-fuel (per GJ), and is 99% generated by hydro-electric.
re cold climate ... considering that lighting makes up perhaps 2% of total household energy use, and heating over 80%. The politics of an incandecent light-bulb ban boils down to a hollow gesture. An inconvenient truth, but this political act smacks of tokenism.
Perhaps in the future, we can look forward to much more concrete, better researched & sincere political leadership on all green issues. For example Canada exports millions of tons of dirty coal annualy to Japan, Korea & China... perhaps we need to ban that before banning incandecent bulbs. Canada has a lot of dirty coal for sale... (will trade for CFLs)
Appologies for the side-track.
The question remains unanswered : What is the overall carbon footprint of a 60W incandecent (100% efficient during 80% of it's usage span) vs that of a 13W CFL. The answer should account for all materials, manufacturing, shipping, lifetime energy usage, displosal.
