One thing I haven't seen mentioned elsewhere is that the energy savings of LEDs may not actually be what you expect. We heat our home something like 330 days of the year. If we use LED bulbs instead of incandescents, we just have to run the gas furnace more to make up for the "saved" heat energy.
Add in the fact that LEDs have a much higher embedded energy of manufacture, and the fact that they seem to last a lot less than the 10 years they're specced for, and switching my house to LEDs appears to have increased our carbon footprint. Plus now we're using more heavy metals and such in circuit boards. Aaaaand the light sucks.
