I learned years ago that the secret to CFL's is that you get what you pay for. If you buy the cheep ones they are extremely fragile, and they don't last as advertised. I replaced the 130w bulbs in the funeral home (36 bulbs) with the CFL rated for the fixture. When I purchased quality ones they lasted several years. The "money man" complained about what I spent, so he went to a place I will not name but call "W" and purchased the supply for me. After getting 3-5 years out of the quality, I was getting 18 months and less out of the bargain CFL's (that is less than I got out of the incandescents).
During my stint, 10 years, on our local Utility Commission, we were constantly pushed by the government to push these things. I am not against conservation, but I asked about the mercury issue. The greenies push the issue of mercury from power plants, but I pointed out that we are now putting mercury in every light socket in the community, and most of those are being thrown into the regular waste stream. I was told I was wrong about the waste stream, because that is illegal - How many people follow that law, or even know about it?
On to another thought - Carbon Sequestration.
Do you want to see an engineer's head explode and a Sierra Club protester jump down your throat? At a public meeting, ask them what possible issue there could be with taking super heated liquid carbon collected from power plant stacks and pumping it into "spent" oil wells. When I asked that question in St. Paul the plan was to pump this liquid carbon from 300 - 500 miles from plants in Nebraska, South Dakota, and Minnesota to oil wells in North Dakota. Wells on the edge of what is now called the Bakken Fields. The only rational response I got was an engineer who said "Hummmmm."
