I think we have come to a classic conflict here. Some of us think that mitigating the damage we do to the environment is a high priority. Some of us think it is less so.
To the second group, it is easy to ignore the tons of CO2 dumped into the atmosphere by using the less efficient alternative.
To the second group, they can't be bothered to make a once a year trip to their local recycling facility so they can't imagine it as a responsibility of citizenship (or adulthood).
To the second group, the inability to use a cheap dimmer on a CFL is too great a sacrifice for us to ask. (Dimmers are now available for CFLs, but you will have to replace the one you have now.)
To people who know in their hearts that we should treat our environment better, but find it too inconvenient or the moralizing wuzes (their phrase, not mine) too annoying, they have their excuses. Human beings are very clever, especially when searching for a way of justifying a lesser effort.
I am fascinated with the potential for using LEDs for lighting. They will be more long lasting and less fragile than CFLs, once the price comes down. But let's get real for a moment.
LED lamps are not just expensive. They are $1000.00 a room expensive. We may well be using solar panels to power our homes and hydrogen cars before the price of LEDs come down to the $100 for 1600 lumen (equivalent to a 100 watt incandescent) LED array.
The other excuses have been addressed in other posts. Stop telling me that no one will bring their compact fluorescents to their local recycling center. Start making yourself a good example.
