Especially the ones that don't use DFI or FI, like my engine, which has carburetors, I think I've found a way for you to make up for your sins. Some pennance if you will.
Now, if you believe that greenhouse gasses are killing the earth (actually, they are not, but you'll never convince a Kyoto protocol nutt-case that 98% of greenhouse gasses are water vaper, I digress), you can change one light bulb in your house and if we all did it, changed one lightbulb to a compact flourescent bulb, we could displace the polution made by 1,000,000 stinking, useless gas sucking cars and SUVs.
Now, you must know that everything that Mark does is to the extreme. So it started out small, yeah, one CFL to replace another. I had a pretty good source of CFLs that offered them for way less than market value, so I bought many of them. Now I needed some special application CFLs, like reflectors for recessed fixtures, and I needed some tiny mini ones for my ceiling fans, and I need some big-uns, and little uns and all sorts of 'ems. And some of these little bastards are expensive! The overhead lamps in my shower and bath were 60 watt floods, I replaced them with CFL reflectors that were ten bucks a crack, but they only use a paltry 11 watts to produce roughly the same amount of light.
It cost over 26 bucks to do my one ceiling fan with CFLs that had a covering to make them look like regualar bulbs for cosmetic purposes. I need five more of them to complete the job (I have a fan in the living room where I don't use the lights very often, but I'm replacing them anyway).
The ones that really save me money are the hidden ones that my wife and daughter leave running when we go to work and school. It is so easy to leave a closet light on, or a bathroom light, so I replaced all of those. I personally would never leave a light burning all damn day by accident...

. Still, it was sound strategy to get those in the closets and bathrooms, because those are the ones that will be burning when I get home for lunch. And bitching at my wife just gets me cut-off, so I recommend these bulbs.
My real motivation for the interesting and informative post? OK, I quit dipping a couple of days ago cold turkey and I'm ready to whip some arse. Nicotine withdrawal is like being ill, so I'm self-medicating with these beers here.
Seriously, though, if you haven't considered CFLs for some of your home's lighting, or if they've always seemed too high, the price has come down, the technology has improved and they are more energy efficient than ever. I'm saving 25 percent on my electricity bill a month. That's some dough! Yeah, I spent a couple of hundred dollars swapping all the bulbs and changing a couple of fixtures, but it's gonna pay in the long run. And CFLs last 10 times longer than incandescents. Still, for dimming fixtures and a couple other appliations, standard bulbs might be best.
Good luck bulbing!
