Over 99 percent of the petroleum used by
Pennsylvanians comes from Louisiana and Texas, or is imported from overseas. Approximately
85 percent of the natural gas consumed in the Commonwealth comes from out-of-state North
American reserves. On the other hand, approximately 80 percent of the coal consumed
in the Commonwealth, including that used to generate electricity, comes from Pennsylvania
mines.

1996), a seven percent increase from the proceeding year.
Coal

electric power contributed 22 percent; hydroelectric 13 percent; natural gas 10 percent;
