You may ‘have seen ‘those
pictures that show heat as if
it were light. This is called
infra-red photography, and
with it you. can:..see' the. heat
escaping from homes in‘ cold
‘weather. A house or a whole |
town filmed from the air will
often look as though it were
going up in flames. That’s

how _ bad the. cheat losses

usually are. 7

As individuals, few of us
wv! can “afford to throw money

away on heavy: fuel bills. As a
mation, we can ’t afford to use
precious energy resources to.

warm up: the sky-:and the
_ show piles around: | our

homes. Thorough insulation
can cut the year’s heating bill
by as much as _ half, and
similarly save resources that
‘produce the heat. The size of
these savings will depend, of

_ things ‘worse by increasing
