 From that same site, you may want a copy of this PDF from the Food and
Agriculture Organization of the United Nations (FAO):

Some of the scanned graphics are a bit rough, but it looks like a good
reference (and it has six pages of references for additional reading).

As an experiment I learned to live with just a small dorm room
refrigerator that draws 100W. It's old, not Energy Star rated, but the
KAW shows it using only 11.5 KWH a month.

 "Energy Star" is a special label that manufacturers buy stickers for certain
models they want to promote and does not mean the most economical energy
wise units. It's a crock. Many models from the same companies are less
energy to run. Hard lesson for the sheeple to learn sometimes.

Instead of this silly (unless, of course, you want to make a new
full-time career tending a gasifier or digester) crap that has been
recommended in this thread, why don't you do the following:

1) replace the gas generator with a unit optimized for propane.

2) Install a propane tank large enough to run you a full year so you
can buy your gas in the summer when prices are lowest.

3) contract to have to some of that unlimited firewood logged to pay
for said generator and fuel.  Re-plant the areas logged in the fastest
growing, most economically valuable trees available for your climate
and location.  Your local ag extension agent can advise.

Propane is extremely favorable vs gasoline as a generator fuel.  Just
a couple of days ago I bought my year's supply for $.44 a gallon.

Generators optimized from the factory for propane (higher compression,
more spark lead, good clean intake tract, etc) are very miserly.  For
example, the Generac QuietPack 5.5kW LP version is rated at 1 gallon
per hour at half load and 1.2 gallons per hour at full load (shows why
you want to run the generator fully loaded when battery charging).
That's about half the cost of an equivalent gasoline powered generator
feeding on $/gal gasoline.

I have the gasoline version of the QuietPack and cannot recommend it
highly enough.  It's so quiet that you can sit on the thing and carry
on a conversation.  3 wires remote control and capable of 120 only or
240/120.

As another example, I have recently installed a Generac 10kW automatic
standby generator for my cabin.  Propane powered.  It is rated at 1.25
gallons/hr at half load and 1.9 GPH at full load.  It will run at half
load or less essentially all the time.  I had to have the 10kW to
start my central AC unit.

You probably don't need even the 5kW unless you have one heck of a
battery charger so a smaller generator will do the job.  I don't have
any recommendations or experience with smaller LP powered generators.

In any event, going the LP gas route will be the cheapest PRACTICAL
thing that you can do.
