model answer:

The two graphs show that oil was the major energy source in the USA in both 1980 and 1990 and
that
coal,
natural
gas
and
hydroelectric
power
remained
in
much
the
same
proportions.
On
the
other hand, there was a dramatic rise in nuclear power, which doubled its percentage over the ten
years.

Oil
supplied
the
largest
percentage
of
energy,
although
the
percentage
decreased from
42%
in
1980
to
33%
in
1990.
Coal
in
1990
was
the
second
largest
source
of
energy,
increasing
its
proportion
to
27%
from
22%
in
the
previous
decade.
Natural
gas,
the
second
largest
source
in
1980 at 26%, decreased its share very slightly to provide 25% of America’s energy ten years later.
There was no change in the percentage supplied by hydroelectric power which remained at 5% of
the total energy used. Nuclear power the greatest change: in 1990 it was 10%, twice that of the
1980s.
