Alison Zeuschel
and
her
family
decided
to
move
to
the
countryside.
Their
home
hunting
ended up in a very small town in
Arizona where they purchased a house
on
40 acres that was not only off the grid, but
without access to any
(public)
utilities. Just imagine the challenges facing
them, such as
generating
their
own
power
and
hauling
their
own
water.
However,
they
worked hard and succeeded in making the
adjustment in a few months.
In
addition,
they
benefited
a
lot
from
living
off
the
grid
there.

important
of
all,

came
to
know
the
importance
of
conservation
and
learned how
to
conserve power
and
water and
how
to
reuse things, etc.
In other words they
learned how to live green.
