Well, I was born and raised in Nova Scotia in a town with a an aging steel mill and defunct coal mines so I don't have either an Ontario or Toronto centric opinion. I have a clean air issue and if you have to pay $.02/kwh more to get thousands of new jobs and start industries that WILL NOT need to be subsidized in the future, that is a price I am willing to pay. If you want to live in the past while others progress around you, you can still get bags of coal delivered to your door. I had to shovel that stuff into our furnace when I was a kid and it was not fun.
I also had friends with "black lung" and thats no fun either.

Look, I'm not arguing coal is a good idea, an the notion of "clean coal" is a cruel joke.
My point is that the world needs oil, and would prefer to buy it from a secure source not run by a tin pot dictator or have their money support nefarious causes.
Solar is great too, when it works and when it can compete.
You speak of Alberta ranchers with bad wells? What about the people living under wind mills complaining of unexplainable health problems?

TECHNOLOGY. It moves quickly. Truth today becomes inaccurate dogma in 15 minutes. It's really hard to stay on top of current circumstances.
Remember the early Compact Flourescent bulbs? Not very compact, took a long time to fire, and light quality was terrible more often than not. I still get people referring to the experiences they had with bulbs 20 years ago as excuse to hate CFL's.
Solar panels have gotten so cheap they can compete with the power plant in many areas, even without subsidies.Which makes more sense to you?
CONSERVATION - turning your thermostat back and being uncomfortable. Maybe saving 5-10%
ENERGY EFFICIENCY - leaving your thermostat where everyone is comfortable. Saving 30-70%
DO THE NUMBERS! Step on a HOMESCALE.
What is comfort? Well, it AIN'T just TEMPERATURE!
Energy Obese? An audit is the next step - go to BPI.org, or RESNET, and find an auditor near you.

Ain't that the truth. Of course CFL will be starting to be phased out as well soon now that LED bulbs are hitting the market.
Solar has come a long way. With some of the recent break throughs the idea of a decentralized power network starts to become a little closer to reality.

LED's don't have THAT much better lumens/watt than CFL's, so I'm not sure the CFL's will really have a very aggressive phase-out schedule. The also haven't gotten the high-lumen systems out there in any competitive numbers for LED's yet. Just spent quite some time looking for some 100W equivalent dimmable bulbs for my kids rooms, and there is just nothing out there on the led front that can do it yet. Got some 23W dimmable CFL's, and honestly, the color is VERY good on them (3500K, really close to a good halogen bulb). Plus, the UV component of the CFL's really makes their glow-in-the dark stars on the ceiling come to life in a way they never did with the incadescent bulb I replaced... :-)

Is "dimmable" the failure point? I'm seeing a lot of LED's in commercial spaces that IMO look better than CFL or incand.

THe main advantages of LED vs CFL is longevity and lack of mercury. At the moment you are absolutely correct about them. They are to expensive and do not have the output to replace halogen, although I'm sure that will be coming in time. That being said the idea have having bulbs last for decades is appealing.

dimmable is part of the failure point, though that will come. The other failure point, is light density and focus. LED's, having a primary illumination direction, require some extensive lensing/element arrangement to get an even near-360° Light that a traditional incadescent or CFL have. This has been part of the problem in residential adoption - and why companies like Switch have gone with an oil filled light (as well as it's thermal dissipation capabilities) and why phillips is using a remote phosphor surface to emanate light in a more disperse pattern - added complication that still makes their newly displayed 100W equivalent LED household style bulb still use the same amount of power (23W) that the CFL does, but cost 5 times as much. The dimming capability IS better on LED bulbs that support it, being able to got down to near 0% dimming, where CFL's are usually limited to around 15-20% or so.
Commercial spaces, on the other hand, HAVE seen better LED adoption, but that is because they are most likely not limited by the standard household fixture. LED light is perfect for indirect light-bar type applications, and for directional lighting (R20, R30, etc), which are used quite a bit in commercial can lighting. I, personally, have in stalled a lot of LED R20 and LED PAR38 bulbs at work, and I do expect them to last a VERY long time. But, they are directional lights, and are not dimming uses.

I just switched my entire house over to LED lights in an effort to save on our electric bill.
I am pretty disappointed in the light output as a whole compared to CFL's and incandescent.
You do get used to it though. I had to add a few CFL's back in the mix to even out the lack of lighting, especially in the basement.
Technology will get better with LED's and residential lighting.UA LU189
10mm, because it's better than .45acp
