The

obtained

from two well-known supermarket

groups,

A

The annual energy consumption by

supermarkets

in O n t a r i o

and

Quebec

is reported in Group A

for

t h e

year

1977

whereas

for

supermarkets in

Group

B ( l o c a t e d in Ontario) the annual

is

reported f a r

consecutive years,

1978 and

1979.
