People
began
to
use
the
energy
from
the
sunlight
in
different
ways

We
can
use
it
to
warm
the
house
in

winter,
to
heat
the
water
for
baths,
and
to
produce
electricity.
What’s
more,
we
can
even
use
it
to
run
vehicles
directly
in
the
near
future.
As
is
known
to
us,
the
energy
from
the
sunlight
has
a
lot
of
advantages.
For
example,
it
is
clean,
renewable
and
non-polluting.
Besides,
it
does
no
harm
to
our
nature.
So
we’d
better
use
it
as
much
as
possible.
You
