Erm, I don't think that was preaching.
Just responding with some "Scientific Evidence".

My 987S does 28 (UK) mpg average, which isn't too bad.
Could be worse, could be a huge SUV that does 12mpg or less.

Elsewhere in my life (since you poke the finger) I use energy efficient appliances and bulbs wherever possible, and recycle 70% of our trash. I buy locally sourced food wherever possible. It hasn't affected my quality of life to do that.

I just don't know why some Americans are so keen to shout 'Green is Bad'.
