Hi Chris, Mar 29, 2010
You are correct re disadvantages of incandescent bulbs in the =
multi-unit commercial setting where excess heat is frequently a disposal =
problem.=20
I had intended to restrict my defense of incandescent to the =
single-unit residential context but forgot to spell this out.

Hi Wayne & All, March 28, 2010
Pogo, in about 1957, said it long before limits to growth and =
said it best, while looking our over a swamp fouled with tires, auto =
batteries, cans, bottles, etc.; "I have seen the enemy and he is us."
These earth hour sessions may have some positive consequences =
but I wonder if earlier sessions are responsible in part for the idea =
that incandescent bulbs are somehow undesirable. [In our latitude nearly =
all of the heat generated by incandescent bulbs is welcome; apart from =
15-20 evenings per year.] In 2007 I calculated our estimated annual =
usage of power for lights as a percentage of average residential power =
use; a whopping 4.5% !
Has the message been corrupted by simplistic interpretation and =
the desire, in some quarters, to finally find a market for fluorescent =
bulbs ?
Out previous government established Conserve NS, partly to push =
fluorescent bulbs and our present government plans to (perhaps has) move =
this function to a private agency. One effective way to conserve energy =
would have been to turn off the lights at Conserve NS and spin-offs; =
permanently.
Rather that pull the main switch for one hour per year, surely =
the message would be more convincing if one were to use power sparingly =
for some 8700 hours per year.
I take your point, however, I wouldn't be so quick to discount the =
importance of symbolic acts. No one associated with Earth Hour pretends =
that turning off/down the power for one hour is the answer to climate =
change. The message is intended to both:
1. Draw attention to the issue of wasteful use of resources (such as =
power) on the part of the public, thereby contributing to making people =
consider (and perhaps even act upon that consideration!) what they could =
do more intelligently and frugally over the remaining 8,759 hours; and
2. Collectively exhibit that broad public support (i.e., translatable =
to electoral support) that will help galvanize or empower politicians to =
take similar policy and legislative steps.
Also, I don't think the energy wasted with incandescent bulbs is so =
easily dismissed (a rather poor way to heat a house, I should think ... =
;->). I recently saw the results of a study commissioned in the USA (New =
York sate, I believe, but it could have been Massachusetts) on the =
savings that would be realized by changing all the light bulbs in public =
buildings (hospitals, police stations, government office buildings, =
etc.) from incandescent to fluorescent. It worked out to the energy =
equivalent of removing several thousands of vehicles from the road (I =
can't put my fingers on the story, and hence the exact number).
As for fluorescent bulbs, when I bought my present house ~ 8 years ago =
I installed them wherever possible throughout the house. I bought 2-3 =
spares as well, to have on hand when they needed replacing. In that time =
I haven't had to change a single one and my spares gather dust in the =
basement ... ;->
Cheers!
