I agree: make the investment up front.
I guess what comes into the mix is just what is this material that we are 
using for insulation? Where does it come from? What is it true cost?
I also agree that creating a building that requires much less fuel is a 
worthwhile accomplishment; however, what exactly are we using when we use 
standard insulation materials?
and why isn't hemp available?
and what, if anything, can we do to change that?
Thanks for the link to archival fodder, L!

Over the years I have posted my knowledge and hands on experiences with
a number of insulation materials used in construction and how they are
used and installed. I went into a lot of detail in some posts. I have
been there and done that, built the highly insulated buildings.

Make the up front investment and reap the rewards for many years. Build
better, not larger.
Basic materials:

foil and foil-backed insulation, flexible foam panels

rigid foamboard panels

spray on foam insulation, hard-setting, waterproof only

insulating concrete/masonry products
Hebel & Aercon products, blocks and steel reinforced panels

log construction

Heating options:

Russian stoves
Finnish stoves
Masonry Stoves
high efficiency wood burning stoves
Rocket stoves

solar thermal heaters, reflectors and collectors
solar closets (Google Nick Pine)
