Incandescent vs Fluorescent Light Bulbs
Which one causes more environmental damage?

Incandescent uses a tungsten filament, who's melting point is 2422 C. Since it is the metal with the highest melting point known to man, it is ideal for light bulbs. The other element with a higher melting point is carbon (actually, it doesn't melt, but it sublimes at around 3700 C)

Tungsten can be considered a semi-expensive metal. More expensive than iron and aluminum.
Unfortunately, no one recycles light bulbs as far as I know.

When you throw a light bulb away, you throw away glass, steel, lead and tin alloy, copper, tungsten and the nitrogen-argon mixture.

Compared to fluorescent, incandescents are safer for the environment.
Fluorescent bulbs contain mercury vapor (chemical symbol Hg). Even those large fluorescent tubes contains mercury.
And for some reason, nobody recycles them. They just gets crushed and the mercury vapor goes straight into the atmosphere. The Compact Fluorescent Bulbs (CFB) contain from 5 to 10 mg of mercury. I don't know how much the larger fluo tubes have.

Some say that fluorescent is better since they consume less energy.
True, they do emit more light per watt.
Unfortunately, during winter, you don't save anything since you have to heat your home anyway.
I live in Quebec, so we have a long winter and so does the rest of Canada, except for British Columbia.
Also, during winter, my power bill quadruples because the water heater and stove and heaters are all electric.
If we can harness solar power, it would help reduce my consumption.

Some say that burning coal releases mercury.
True, but where I live, it is hydro powered, not coal powered. I would be doing a lot of damage if I use fluorescent. It just doesn't make sense to use CFB but the government and some bullshit organizations kep recommending that people use it. Where the heck is mercury mined anyway? Some 3rd world country and we don't care if they kill themselves breathing the mercury fumes?

Some say fluorescent lasts 12 times longer.
False, in my experience it is more like 2.5 times longer, but I had limited experience. The bulbs I used were made in china and in my experience, manufacturer defects are common in everything they make.

Conclusion
1. The best solution might be LED based lighting although I didn't talk about it.
2. Fluorescent has no advantages where I live. They don't reduce my electric bill and harm the environment.
3. For some reason, nobody recycles either type of bulb. I do have a small bottle full of tungsten but what should I do with it?
4. You are coal powered? I suggest switching to hydro, wind or solar. Yes, the cost of building a plant is astronomical but what are you going to do? Use coal forever? The rich people who run those coal companies-oil companies don't give a damn about you and the future.
