Since I am not usually home until after dark and up for a good portion of the night, converting to CFLs has created a SIGNIFICANT impact on my electricity spending while permitting me to get brighter lighting (what were only 60W incandescent are 100W equivalents now).
Here are the things I read that I want to address:
BEWARE! MERCURY!
True, most CFLs sold have mercury plus a significant amount of plastic because they did not go the ballast + plug-in bulb route.
However, that in and of itself it not bad - don't forget that most of us who drive around have a chunk of lead in our vehicles. However, lead-acid car batteries are one of the great environmental success stories.
The up side to the story is I see more and more places that sell CFLs having recycle drop offs, just as I see more stores having plastic bag drop-offs. With proper recycling, the existing use of mercury can be mitigated while waiting for better alternatives (like the developing LEDs, which I have only seen at my retailer in 40W equivalent accent lighting bulbs).
WHY IS THE GOVERNMENT INTERFERING WITH THE FREE MARKET!
Well, we don't really have a free market - most economist say that would be bad. Most countries have some level of regulation - and the countries in question utilize procedural over substantive regulation (guarantee equal playing field versus equal outcomes).
However, all that aside, a government has a vested interest in maintaining an ailing energy grid while growth keeps increasing demand. While one bulb might not seem like much, when you change every bulb in every home in all the nations of the world then the reduction on the grid will be substantial.
For industry, the extension to the grids life span versus costly upgrades and expansions could be significant. Also, at upwards toward 75% reduced energy, this means the consumer can add other electronic devices to use while still reducing their cost in electricity (and maybe more inclined to spend that money).
THE GOVERNMENT IS FORCING ME TO BUY MORE EXPENSIVE BULBS
When combining the increased lifespan of the bulb with the reduced energy consumption, the government is actually forcing you to put your lighting costs more at the beginning and end of the products life cycle. (The initial cost of the bulb + the unspoken cost of disposal/recycling of the bulb.)
THE CFLs DON'T HAVE DIMMING, WARM COLORS, AND SO FORTH
They are not perfect, but they are far improved from CFLs of 5 years ago and a decade. When manufacturers are forced to abandon incandescent technology, more will be able to put money into CFL and LED research and come up with new and competitive alternatives.
To add anecdotal evidence, I recently purchased dimming CFLs and found they worked just fine. If I want the light any lower, then I can always burn candles (again, with due caution as many slow burning candles also contain metals - but they get vaporized). I also have found a good variety of light spectrum available, and I am willing to put a tint of color on my walls to change the quality of reflected light.
------------------------------------------------
Note, I did not mention global warming at all in the above? When considering infrastructure and energy security, doing away with incandescent bulbs and implementing car-battery like recycling programs make a lot of sense.
Just remember, when discussing alternatives and solutions, realize there is no such thing as "clean energy" or a "clean solution" - only cleaner or different options. Anything we do will be a disruption to the environment, but that does not mean we should not strive to look for ways to minimize our impact.
