Making my footprint a little smaller?

Last night I signed up for 'Greenmax', the program where I pay an extra $6.50 a month so that my share of the Alberta power pool comes from wind-generated power. Cool. Here were my questions, if you have any answers I would really appreciate it...

1. why should i pay extra for energy that is free? it just blows around until we harvest it....
   
2. why should people have to CHOOSE clean power rather than dirty (coal/nuclear/...) and
3. shouldn't somebody just say this-is-where-we're-going-so-deal-with-it and we're all going to chip in a bit extra to deal with the investment this is going to take to develop
4. why didn't somebody send me a brochure about this? i signed on for paperless billing *you know, to save the trees* but as a consequence nobody told me i could also save hunks of coal because i don't get those annoying inserts with paperless billing (a pro and sometimes a con)
5. why isn't everybody doing this?
