I am an engineer as well, not chem, but still I tend to agree, mostly, with
the URL's scenario. I am currently building a new home. It has
SIP (Structural Insulated Panels), Geothermal heat pump (ground source
heat pump), passive solar heating, and, perhaps, solar panels. (My previous
home had a 6KW solar array). I've been driving a Honda Insight for 4 years.
I know this is all just pissing in the wind so far what's in our future,
but it's the best I can do.
