THE OCEAN SHIPPING SECTOR (I.E. FOREIGN TRADE) USED 80% OF THE ESTIMATED 2.95 QUADS OF ENERGY USED BY THE MARINE TRANSPORTATION INDUSTRY IN 1974, ACCORDING TO A RECENT STUDY CONDUCTED UNDER AN ERDA CONTRACT (SEE TABLE BELOW).

Table 2.13

OVER

CURRENTLY ONLY ABOUT 19% OF THE ENERGY USED FOR FOREIGN SHIPPING IS
ACTUALLY PURCHASED IN THE UNITED STATES: 81% IS PURCHASED ABROAD.
90% OF THE TOTAL ENERGY IS USED BY VESSELS REGISTERED UNDER FOREIGN FLAGS
BUT ENGAGING IN U.S. COMMERCE (SEE TABLE BELOW). CONVENTIONAL ESTIMATES
OF ENERGY USE BY THE MARINE SECTOR OF THE UNITED STATES HAVE NOT TAKEN
THESE FACTS INTO ACCOUNT.

A CHANGE IN THE BUYING PATTERN INDICATED ABOVE COULD SIGNIFICANTLY

INFLUENCE TOTAL U.S. ENERGY DEMAND AND CONSUMPTION. FOR EXAMPLE, ALL
ALASKAN OIL MUST BE TRANSPORTED ON U.S. SHIPS. THEREFORE, IT IS EXPECTED

THAT DOMESTIC ENERGY USE WILL INCREASE. ALSO, IF THESE U.S. SHIPS "FUEL
UP" (BUNKER) AT U.S. PORTS, THE TOTAL ENERGY USE IN THE U.S. WILL INCREASE.
