One of the only drawbacks to these light bulbs is the fact that they contain mercury. Though this is true, there is only and average of 4 milligrams of mercury in each bulb which is a very minuscule amount, and as long as the bulbs are intact they will not release mercury in to your home.
These particular bulbs are 26 watts that are equivalent to 100 watts of incandescent bulbs and last 5 years.
Another way to light your home is using natural sunlight through windows and skylights. Skylights can be very useful for high traffic areas or rooms that tend to be very dark. Instead of putting up a light fixture you may want to consider a skylight.

One user said he replaced all the light bulbs in the elevators of his business and saved $3,000 a year on electricity!
I too have drank the CFL cool ade to try and save money, but the bulbs I've purchased have lasted just as long as any incandescent I've used. I've already replaced a few and am holding on to the burnt out ones.
In retrospect, I pay more for bulbs now than I ever did, and because CFLs will be the dominant bulb in the very near future there will be more of them in landfills...but I'll save 50 bucks on electricity this year.
We humans are terribly inefficient when it comes.
A dishwasher is a short distance closed-loop water filtering system. It can be efficient and simple because it is not required to filter out body waste, agricultural toxins, oils and the myriad of other things that enter a municipal water treatment plant.
A dishwasher uses a limited amount of water over and over again. Once it is heated it stays hot so it's not constantly drawing hot water from your heater that loses a lot of heat on its way to your sink.
