Haven't read this entire discussion yet, but I'd like to add my two cents...
I believe that global warming is pretty darn obviously going on. The evidence is there, and the whole debate about it is just like the debate about cigaretts causing cancer. Just like the hole in the ozone layer, this is a real problem and it can be fixed.
In response to this, I read everything that I can to stay informed of both sides. I also primarily commute on motorcycle, I use public transportation whenever possible. Also, I'm planning on buying a truck in the near future, I'll be buying a diesel truck so that I can go the cooking grease route for powering it, or at least biodiesel.
My power bill is also generally under 15$ a month, I turn off everything when I'm not using it.
