Where
in
the
World....
...can
you
use
solar
energy?
You
may
think
that
solar
energy
only
really
works
in
hot
places,
where
the
sun
is
beaming
down
all
the
time.
Wrong.
In
fact,
there
is
enough
"insolation"
(a
fancy
word
for
how
much
solar
energy
reaches
the
surface)
in
most
places
in
the
world
to
generate
substantial,
usable
electricity.
With
just
3
kilowatt-hours
per
square
meter
per
day,
a
highly
efficient
photovoltaic
array,
and
a
properly-engineered
battery
system,
a
single-family
home
can
get
enough
power
to
sustain
most
activities
everywhere
it's
green,
yellow,
orange
or
red
on
the
above
map
--
in
other
words,
virtually
anywhere
in
the
world,
even
the
frigid
Antarctic.
As
Charles
Gay,
noted
solar
energy
expert,
says,
"While
the
amount
of
annual
sunlight
which
falls
between
the
two
arctic
circles
varies
by
as
much
as
a
factor
of
3,
solar
cells
have
a
self-compensating
character
so
that
the
amount
of
electrical
output
varies
by
as
little
as
1/3
between
bright,
sunny
areas
and
hazy,
overcast
locations."
Naturally,
the
more
red
the
map
becomes,
the
stronger
the
insolation,
and
so
the
more
you
can
do
with
solar
energy
in
those
locations.
The
bottom
line:
solar
energy
can
benefit
most
people
in
the
world.
It's
a
matter
of
delivering
the
right
equipment
to
the
people
who
need
it
most,
and
identifying
uses
for
the
power
that
create
economic
benefits
to
justify
the
cost.
That's
what
Greenstar
makes
possible.
The
first
Greenstar
installation
was
begun
on
the
West
Bank
(Palestine)
in
December,
1998.
